100th upload! Hot damn that's a lot of videos... Support that channel and help it grow through checking out my new merch: teespring.com/search?q=auto%20autopsy

[@rasgum7]

Loving your videos. I have a 05 9-3 ARC 2.0T. I bought a new turbo to replace the leaky one. Have you had to replace your turbo? If you any guidance would be appreciated. Keep the vids coming.

[@AutoAutopsy]

I have not; I would assume it's not terribly difficult since it's the same part as before. I bet there's DIY guides online for it. Good luck!

[@rasgum7]

Thanks for the quick response. I am searching but cant seem to find anything as far as DIY. Surely it's on the web somewhere. Any recommendations as far as a Plug n Play Tuner?

[@AutoAutopsy]

I think most Saab tuning companies sell handheld tuners. Try out sites like Maptun, Brew City Boost, JZW tuning, etc. They're all slightly different and it really boils down to personal preference

[@urbanjentry222]

I love your your enthusiasm for a understated brand

[@harisjaelani2531]

I have a 2003 9-3 2.0t and noticed it can turn sharp corners really well and is really stable to make sudden turns like to avoid a collision. I once narrowly avoided a high speed collision. Not sure how to describe it but it felt like the car was extremely stable and 'glued' to the road. It didn't feel like it was about to flip. Where I want the car to go, it will go there with ease. Comfortably. Excellent stability. Maybe this is where the ReAxs really helps?

[@AutoAutopsy]

Yep, it's mostly a safety and stability feature

[@albanitlondon4147]

Yeah and they also have anti roll bars meaning the car will not lean when cornering

[@ryangarner8124]

I love this feature on my 08’ Saab 93, 2.0T Not a waste, it saved my life while driving at a fast speed on expressway, and had to brake and swerve around an animal and the Stability control system on this car held the road like glue… and I didn’t have an accident or spin out of control. Thankful for Saab technologies

[@AutoAutopsy]

🙌🏼👊🏼

[@bryanswenson1452]

I would say aircraft engineers know a lot more than regular car mechanics. So hats off to Saab.

[@AutoAutopsy]

It's quite impressive!

[@bryanswenson1452]

Auto Autopsy It was almost $50,000 new. That impresses me.

[@Harrington_35]

And mechanical engineers know more than both of them 💁🏽‍♂️

[@xxdfoster]

Easy to assume but , yes most airplane wrenchers may have started out with a old Honda four wheeler/beater car!

[@doitall8877]

Oh my god, this is what saved my life on my 54 plate model 9-3. I got cheap tyres for the first and last time. The car skidding going around the corner, next thing the car turned all the way and faced the opposite direction which was the safest thing otherwise I would have slid into a bus stop and onto people. Thank you Saab. It was raining and the road was wet. If you save a life, it's money well spent. They were definitely different and that's why I love them!

[@AutoAutopsy]

Wow, that's scary! Glad you're okay

[@doitall8877]

Auto Autopsy Yeah, this was about 3 years ago. I felt totally safe and the people on the stop thought it was a special move as the car perfectly steered onto the opposite side. If it aqua planed it would have smashed into rail and if it lost control or under-steered, it would have collided into people. I'll never buy budget tyres again.

[@rainbowboii9512]

You did a great job,of explaining Saab's ReAxis technology.I've never heard of it,before.I kinda think,it was a waste of money that could have been spent on trying to save the company instead.I wish they were still making cars.Congrats on,your 100th video!.Keep em coming.

[@AutoAutopsy]

Thanks, I appreciate it!!

[@AlexLester1]

I’ve noticed it! Along with the many cars, 440i’s, e46 and e90 m3’s, my friends fully built e36 gcams, bilstein coilovers, sway bars, stripped interior, roll cage, m3 brakes, carbon body panels, etc) that I have kept up with and or left them behind on tight back roads. It’s funny to give ride alongs when I am going 100% because the comment I receive the most is “how the hell is it not understeering”. The only downside to my car handling so well is that I have to stop and wait every few minutes for my friends to catch up when we go race the backroads 😂

[@AutoAutopsy]

Lol damn, like seriously dude.

[@one2nd1]

The only way I can describe it, and I've never experienced it with any other car throughout my driving history, is this, you go into a unknown surprising sharp turn, your mind is working out what's going to happen, a strong sense that your gona come off the bend, while your still processing your next reaction within a split second, the car has "mysteriously" done the job and got you through it safe out of the bend, I came out in total confusion when that happened because the mind was still trying to workout the next evasive response which was skipped by the car doing it and your there safely out of the bend.

[@AutoAutopsy]

Hmm...where I live, roads are pretty much completely straight, so I don't really get to experience it!

[@0510wa]

iv done that recently, back end gripss 💯👍

[@alexd4437]

Hey man, I appreciate the video. I got a 2007 9-3 (pre-facelift) and I got into a situation on the highway where I had to swerve sharply right and left at high speed to avoid a crash. I was surprised how well the car handled but never thought of it much after. It saddens me that Saab's marketing didn't advertise all the features, some which were ahead of its time. Audi A8 only now has dynamic all wheel steering, there's videos about it too. Maybe Saab's steering works in similar fashion? Perhaps it could be seen with a gopro attached to the side of the rear bumper.

[@AutoAutopsy]

Great idea! I hadn't even considered that. Something I'll definitely try out

[@ashtoncovington7504]

Hell yeah I've noticed, I've taken 30-50mph turns at 135mph+ and felt like I was going under the speed limit. I loved my 06 9-3areo sooo much but sadly it got Tboned very bad. Saved my life tho. I loved that car!!!

[@AutoAutopsy]

Lol that seems a bit exaggerated but they definitely handle well

[@0510wa]

Lmfao 😅🤦‍♂️ behave lad, i know its a Saab but c'mon mahn, its not happening at 135 😆😄.. you probably have a faulty speedo clock, its a common Saab issue😁👍

[@elijahbarr9581]

In my 03 9-3 it is definitely noticeable, but its not a linear change in rear toe. It is more like once the car reaches a certain degree of lateral force the rear tires will toe out to the outside of the turn. You have to corner the car harder than normal to engage it. It happens suddenly, and probably is only there for sudden sharp turns to avoid collisions and such, not there to assist in every turn.

[@AutoAutopsy]

Yep, it was for safety only really. Thanks for the info!

[@markteague8889]

I have never noticed it on 04 9-3 Aero. But then again, I can't ever remember having to corner that hard.

[@RobinI92]

Once you start to push it to its limmits its really helps but scared the shit out off me the first time 😂

[@SeikGames]

Now I need to check it :D

[@jamesgravier]

Oh yeah when I'm hooking off ramps or the sharp bends on i95 north of Providence I can feel the rear turn. You can almost feel like the cars turning from the center or something it's hard to describe but when it happens you definitely know

[@thezaalls]

This is one of my favorite features of saab, yet this is one more thing that modern cars are proud of, but saab used it already more than 10 years ago. Last week I was on a track day, short track with many corners, and there was this BMW m235i and Impreza STI, they both were trying to catch me, but when I pushed my precious to her limits, they didnt stand a chance, so for such a heavy fwd car it is fantastic!

[@AutoAutopsy]

Nice!

[@markteague8889]

Interesting!

[@truballr32]

I wonder how these cars would do in the snow???? I live in New England

[@bilaltariq7819]

porsche did this in the 80s

[@corbingreiner9879]

I know Saab spent a lot on steer by wire. It was to ahead of it's time and freaked people out in the 90's. You've out Saab geek-ed me with ReAxs tech. I tip my classic Euro car magazine to you. lol

[@AutoAutopsy]

LOL :)

[@Jandejongjong]

i drove like over 20 cars in private, but the saab can do easy cornering with his heavy body. its amzing how easy it goes.

[@AutoAutopsy]

It is!

[@Harrington_35]

Cannot express how much I appreciate this video. I'm starting a build on my 99 9-5 arc with a td-04 tuned to 223kw on the b235 This is exactly what I was looking for, I'm going to fabricate this into the rear axle Great stuff 🍻

[@AutoAutopsy]

yeah, it's not a 9-5 feature, but good luck!

[@tonyimusic]

Thank you, good to know as never aware of this since 2004!

[@AutoAutopsy]

You bet!

[@viktorwarhola1525]

Good video. Decent explanation. I’ve never heard of it and I’m pretty familiar with SAABs, not necessarily the GM> versions but nonetheless a great video!!

[@AutoAutopsy]

Thanks Viktor!

[@markettlinger6842]

Thanks, I didn't know about this but it explains my observations regarding a newly purchase 2008 9-3 CombiSport. I've owned 900s and presently selling my 2000 9-3. The elder 9-3 handles so...SAAB...you turn the wheel and the car goes there; on turns it's always stable no matter the road condition. While taking some recent long trips with the 2008, I noticed that steering was tight but different. At high speeds >80 mph, maneuvering was very responsive - almost intuitive and I needed to stay on top of it but still in control. Now that I know about this feature I will make sure to be aware of it to anticipate any control issues.

[@AutoAutopsy]

Yeah it's great!!

[@TheHell666yeah]

Cool feature. I drive a 9-3 almost a year and never noticed or feel it while driving. But it's very very good in the corners. Hirsch performance car :)

[@AutoAutopsy]

Nice!

[@Spike20101000]

The difference is most notable when the ball joint on the toe in arm gets any damage. Then depending on the direction of the corner it becomes frightening. But also have to note other cars with no such adjustment I find just have that lurch around corners as the suspension does the corrections rather than the wheels.

[@AutoAutopsy]

Interesting..

[@SidewayZ.garage]

I have noticed when you go 100 miles an hour into a corner and go really really hard into the brakes it just takes the corner really well

[@AutoAutopsy]

lmao nice

[@RLBscoring]

Super late to this video, but thought I'd comment anyway. I just got an '06 2.8 9-3, and so far I am very much pro reaxs. I've owned pretty much all front wheel drive cars, including two '90s Saabs. I wasn't really looking to feel the rear wheel steering when I took it on some windy roads as I expected it to be more of a gimmick, kind of how you described it. I was surprised to find that this car moves through turns more fluidly than I'm used to in front wheel drive sedans. There's less resistance in the turn than I even had in an all-wheel drive Volvo. I think there's something to be said for the performance aspect of reaxs.

[@AutoAutopsy]

nice! happy to hear you like it

[@neilhallam8028]

In the uk we have roundabouts if you go in hot lift and turn you can then stay on the power and you feel the rear not slide but drive around the corner, good system, on fast twisty roads all you have to do is get the initial turn and the rest is history, you will find yourself almost over turning as it reduces the angle you need to make a turn 😉

[@AutoAutopsy]

Lol nice!!

[@mmm4638]

Bought mine last month on the way back took a 40mph corner at 100mph on dry garbage tires it turned so well and stable i was amazed, i come from car racing background now on 1000cc sbk, point being i can notice slightest feedback and when i took that turn i felt as if the rear turned perfect amount i was amazed, now i find it has rear steering yes i did feel it ive driven anything u can imagine first time i felt the rear but u have to be real fast smooth and agrassive, id imagine if u doing 60 80 100 and something is on the road be it object or dog when u break the steering hard it will help u dodge it without losing control, its very organic feel tho not everyone coule notice it

[@AutoAutopsy]

Wow! Yep :)

[@carlthellama223]

I had a ‘03 9-3 and never honestly noticed it. Granted still the best driving and handling machine I’ve ever owned so maybe it played a role and I didn’t even notice

[@AutoAutopsy]

True, that's possible

[@CardboardSliver]

I've noticed it when I take my '06 2.8 Aero thorough a twisty mountain road. The car just digs into the corners, and feels rock solid, even at higher speed turns.

[@AutoAutopsy]

Nice!

[@yhird]

I will give SAAB engineers the benefit of the doubt on whether or not ReAxs was a waste. As a current owner of three SAABS and a past owner of a SAAB 9000 CSE, I can't put a price on safety, unlike General crappy Motors. If during testing, the SAAB engineers felt that the 9-3 was too demanding under certain driving conditions and needed ReAxs to enhance stability, it's well worth the time and money. Thank you SAAB. Good video.

[@AutoAutopsy]

I definitely agree, and think they should've advertised it more at least; thanks for sharing!

[@codyschulte967]

Yea I know exactly what that whole set up is about. Def love the outcome of it. And almost def. The best engineered setup. Makes handling well and easy to go around tight spots without any worries. I have a 05 Saab 9.3 ARC

[@AutoAutopsy]

Nice :)

[@codyschulte967]

Auto Autopsy but unfortunately I must have pissed off some mustang gt owner... my car got vandalized. And I'm in the process of redoing it. I need alot of parts but it's worth it to me. I love the car

[@AutoAutopsy]

Wow, sorry to hear. Hope you can find who did it!

[@xxxDlewisxxx]

Recently I was given the chance to drive my dads 2005 9-3. I daily drive a 06 9-5 & imo the ReAxis tech makes a good difference. There's definitely a sharper response to steering input in comparison. I especially noticed this on highway ramps. It really makes it feel like the rear is more willing to follow the front. Nothing too crazy, but enough to wish SAAB incorporated similar technology into the 9-5s of that gen as well.

[@AutoAutopsy]

Nice! :)

[@stephenmccallan3159]

I didnt know my 9-3 aero had this but i do know when i hit an off ramp off the hiway and downshifted to 3rd and matted it the car felt like it just hugged the corner the whole way around it surprised me i thought i was going to fast and had maybe misjudged the turn and thought i was for sure going off the road bit no it just stuck right thru the whole corner. It definitly felt way different to me than any other car iv owned.

[@neri14]

wow, I have 9-3 of this generation for over 4 years and didn't know about it

[@AutoAutopsy]

Lol, I didn't really notice it at first either

[@OhBriney]

I didn’t notice the reAxis steering on my first Saab. However, the bushings were shot in the rear end of my second Saab and I noticed THAT. Taking my first off ramp in that car, I could feel the driver rear tire really hunting for its point of stability.

[@AutoAutopsy]

Jeez

[@RaphaelHebert]

We have tight back roads here. I can brake later and corner way faster while still being safely on the grip than with the majority of other cars I've driven with the same FF layout and weight (and I have the combi) and way less under steer. The back always seems to place himself nicely without too much body roll for a stock wagon.

[@AutoAutopsy]

Wow, cool!

[@gazerzgarage9487]

So is there some type of electric control unit or a physical steering link from the column to the rear part of the car? I’d like to know more about how it functions if you’ve got the info to share

[@AutoAutopsy]

I'm not sure honestly, sorry!

[@0510wa]

I own a 2006 saab 93 aero convertible 2.0t. Iv lost the back end a couple of times by coming in to hot into the corner, i definitely noticed the back end doing its magic. The car some how grips and corrects the error.

[@AutoAutopsy]

lol nice

[@meek_meek1942]

I'm pretty late. But if I'm not mixing it up the rear axels saab had a hybrid between individual wheel and dual wheel suspension system in the back. I'd say that it helps in highway mergers with pretty sharp turns. But most importantly it keeps a good balance of comfort and stability. Which means you get the best of both worlds. For example. A brand new Mitsubishi outlander ev could top out at 60Km/h before getting unstable in the merges. But my saab 9-5 2003 which has also been lowered for some reason can take the same curve at 100km/h no problems.

[@AutoAutopsy]

yep! really helps at high speeds

[@valentin-paulmoise6381]

Please, HELP! I have one Saab 9-3, 2008, 2.0turbo, petrol, automatic. Not start the engine when is cold. I change many parts, i was in 4 garage. Nothing. I had the ideea to connect one webasto and now will heat 10min before to start the engine. After heat the engine, start normally. Please, any ideea can to help me. Thank you. Paul.

[@AutoAutopsy]

intake valves i believe is the name. common issue on 07-09

[@NegativePlane]

Isuzu did this on the 1990 Gemini and Piazza/impulse. They called it nishiboric passive rear wheel steering. Isuzu were also part of GM at that time so there may not have been as much research done as you might have thought.

[@AutoAutopsy]

Saab definitely developed this on their own, and wouldn't really put someone else's system in their cars. They only want the best of the best, and it's part of the reason GM shut them down

[@leechristopher5403]

Money we’ll spent I think handles like it’s on rails well done Saab

[@AutoAutopsy]

👊🏼👍🏼

[@MrSmartDan]

I've only noticed it on roundabouts if I hit them hard it's a strange feeling like a rwd car that's just about to loose the arse end but then all of a sudden it points you in the direction you want to go even more

[@AutoAutopsy]

Lol!

[@charleswilson9802]

I love it I have an exit ramp that the speed is 15 around it. it is a complete circle and I can do about 60 65 mph around it I do it a lot on my way home love my 06 9-3

[@AutoAutopsy]

:)

[@edoputrawijaya8772]

Similar technology found on Peugeot 306 and 406 back in late 90s and early 00s. The rear wheels would turn 5 degree max. There are some rods connected diagonally on the rear wheels. And when the car turns, the body roll pulls the rods causing the rear wheels slightly "steer". You might not notice the different because there is no on/off button since it is purely mechanical. But I'm pretty sure the handling is better than the competitors.

[@AutoAutopsy]

Nice!

[@mikejautosandstuff3349]

Hey it been awhile, as I kinda remembered? Didn't Nissan 300zxtwin turbo 1990-1993 have some thing like that? 🙄

[@AutoAutopsy]

Yeah, Saab certainly wasn't the first to use rear wheeling steering, or some variation of it

[@nicks.6341]

Older Preludes had it as well.

[@markteague8889]

Practically all modern vehicles exhibit some degree of rear wheel slip angle variation as the rear suspension is loaded. I suppose Saab's marketing point was really that they spent more time and care tuning it for safety?

[@MyCatInABox]

Mike J I think what you may be referring to is what Nissan called "Hi-Cas" or, in other markets, "Super Hi-Cas". I know it was implemented on North American S14 240SX's and Z32 300ZX's.

[@mikejautosandstuff3349]

MyCatInABox YES!!! Ur right I forgot what it was called lol. My bad, but you really couldn't tell if the wheels where turned by sight. For bad in the day, the Z car was way ahead of its time in my opinion. Probably way more technical then today's z car?🤔

[@extrachannel7457]

I can hit the boost red line in my 04 9-3 with the manual side up and down shifter instead of all auto

[@SimbianMinistry]

2008 9-3 Aero - I did know about this feature, but can't say I've ever felt any 'steering' from the rear... However, the car does feel more 'planted' when cornering at speed, than almost everything else I've owned (apart from a 4WD Impreza I had back in 2012-'13)

[@AutoAutopsy]

that might be it!

[@xxMAGnaniMOxx]

Is this similar to camaros having open differentials? Its not really adjusting the angle of the rear wheels but rather it adjusts how much power is being but to each side. Turning right and your left rear wheel gets priority. I could be completely wrong here but that's what I was told 80s camaros had

[@AutoAutopsy]

No, because these cars are FWD so no power is being sent to the rear wheels where this system is. The XWD 9-3's though, like my Turbo X, have something similar to this!

[@xxMAGnaniMOxx]

@@AutoAutopsy Yea I didn't think about it that way. You are right

[@AutoAutopsy]

👍🏼

[@efrazier0217]

Was this also on the 2003 9-3 convertible?

[@AutoAutopsy]

Unfortunately not, since that was on the older platform :( Good question though!

[@anthony0johnson]

I have a 2003 Saab Vector 2.0t convertible and it has it on mine. notice it when changing the brakes

[@nicks.6341]

Does this feature also exist on a 2007 9-5 Aero?

[@AutoAutopsy]

99% sure it's not.

[@kenziec394]

Does the 9-5 that year also come with Saab's ReAxs?

[@AutoAutopsy]

I'm 99% sure it was only on the 2003+ 9-3.

[@bengtmowitz5012]

No, the 9-5 OG, did not have it. Totally different rear axle, 4-link.

[@pctshooter]

I have a Lincoln LS with passive rear steer and it makes all the difference in the world.

[@AutoAutopsy]

Nice!

[@neilhallam8028]

Only down side if you tow like a trailer it will toe each wheel out slightly and your rear tyres ware out quicker but you have to have weight on the rear all the time for this to happen

[@AutoAutopsy]

🤔

[@kitseros]

Cool

[@AutoAutopsy]

4 sure

[@SheedSoprano]

U should do a video on how to upgrade a Saab like making it faster what's the best methods

[@AutoAutopsy]

Good idea!

[@nicks.6341]

And maybe a video on how to help make your Saab more fuel efficient. (I have an auto 9-5 and if pushed hard she can guzzle.. Huge difference to my manual 9-3!))

[@helloukw]

Drive slowly.

[@london20102011]

Add a Hirsch logo. Problem fixed.

[@rodddrake]

Buy a 1.8t and get it derestricted. 😋

[@richs1357]

I haven’t noticed that or knew that but that’s awesome and why I love Saab’s but someone pulled out in front of me at 55 MPh and they were going like 15 they were in the right lane I was in the left and at the last second they whip they’re car into my lane so I have to slam on the brakes and cut to the right and back left I think if it wasint for that I could have flipped I slammed my brakes on and I stopped so fast I will always keep my 2003 Saab 9-3

[@AutoAutopsy]

Wow!

[@nelsonjaneiro2825]

Nice i have a 93 2.0t and is berry good at high speed👍

[@AutoAutopsy]

Nice!

[@Bootysmoothie]

My car has just over 300k on it now ,it's an 06 but it runs much better than expected lately, i have only noticed it driving too fast on the coastlines in Michigan where i live. My mother is a bit of a car nut as well and drives it pretty hard and can manage pretty high speeds like say 75 in a 35 set of sharp continuous short turns by waters edge or some rocky area. And it performs just as it should but apparently much better than anything she's driven but the be fair these cars are all quite short too in length so I'm sure that bit of give can be exaggerated easily in shorter turns

[@AutoAutopsy]

nice! and yeah it is

[@maxxwong1597]

Most of the researchs must have one or more purpose(s), and I believed that there is a sound reason for Saab to do this. It might not be significent but could do lots for future safey issues !

[@AutoAutopsy]

That's true, but it's not even something they really promoted or advertised with, which I think could've helped

[@jumpmansuprax3825]

🔥🔥🔥🔥

[@RaisingLionsNotSheep]

Saab stands for safety and perfection

[@AutoAutopsy]

;)

[@louiemalvessi]

Yes, i can definitely notice it. Noticed something 'funny' even before I knew about it. Get to a large roundabout and throw the car as hard as you can. You will notice the rear kick out, whuch is very similar to the sensation of a rwd losing traction. Another way to force it is to get into a turn with the power on, in a range where torque is very high, anf then take the foot off while holding the wheel in its position. As the weight shifts to the front you will feel that rather than lose traction, the rear will point the car into the exit of the corner. Cheers.

[@AutoAutopsy]

Thanks for that tip, I'll have to try that out when I get the chance!

[@CarSteve]

I believe it was worthwhile. It wasn't unique to Saab though. Nissan advertised this under their own name "Super Toe Control" in the mid-90s. Mercedes, BMW, etc. also have very advanced suspensions, but they don't necessarily advertise or put a brand name on the feature. Saab had spent a lot of money on this, to improve the GM based car, felt proud of it, and wanted to use it in marketing. I think it helped make a heavily GM car a Saab.

[@AutoAutopsy]

agreed! Lol, I think "Super Toe Control" is a bit too literal of a name and a little goofy

[@Jandejongjong]

i knew this:)

[@AutoAutopsy]

Genius!

[@markteague8889]

Have owned an 04 9-3 Aero for a little over a decade now. I don't think I've *ever* consciously been able to notice the effects of the ReAxs rear wheel steer feature. However, practically all modern cars with suspension demonstrate this behavior to some extent with suspension load. Maybe Saab just spent a little more time tuning it for safety (I guess) and used it as a marketing point. Vehicles with greater slip angle on the rear wheels than the front exhibit unstable characteristics at speed requiring more constant input for the driver to the front wheel steering mechanism to correct. (i.e. Corvair) Just watch NASCAR drivers whipping the steering wheel back and forth to correct for the rear wheel slip angle in turns on any given Sunday.

[@AutoAutopsy]

Yeah, I definitely think it's for safety first

[@richardburchett]

Is this part of the "stability control" feature? I get an error message.

[@AutoAutopsy]

My guess would be yes. If it's somehow broken, I don't really think it's worth fixing

[@richardburchett]

I think so, thanks for the response. I was told there is a sensor in the steering column that is bad on my, he thought from some work that was done before. It would be a big deal to replace it. This sounds like a highly technical feature that, like you said, may not be very noticeable. I've never found any problems with the traction and control. The car feels like it handles well and is stable.

[@larsjrgensen5975]

Without knowing for sure I think it is purely mechanical and a passive system not connected to the electronics. If you build in a "weakness" in the suspension on purpose and at the right spot, the rear wheels will change direction, when the suspension has a high load due to hard cornering. Under normal conditions the wheels will have the correct directions for optimal driving under normal conditions. If it was an active system with motors or sensors, this system would not have remained as unknown as it appears to be.

[@s3nsimilla193]

is this technology exist in 9-3 FL 2008+? :O

[@AutoAutopsy]

Yes, I said 2003+ :)

[@panaintecalin6123]

I did notice a different steering feeling on my NG from driving other cars, thought it's the XWD 🙃🙃🙃 now the mystery is solved 🤓

[@AutoAutopsy]

I don't think the XWD 9-3's have this

[@panaintecalin6123]

You mean XWD in general or specifically 9-3's? I have a 2011 9-5 NG Aero, takes turns very firmly, different from other XWD cars I was driving occasionally. Do you think this car might have this feature?

[@MrHeHim]

One of the reasons noted by firms that went into the books of Sabb after their closing was that they were over engineering a lot in both R&D and materials. But it might not have been a contributing factor. Also, the 2008 market "crash" helped kill a company that was a low volume by comparison in the "premium or niche manufacturer" space. Didn't hurt that the 2008+ cars looked both dated and worse than any other premium car on the road, and you can say the same about Pontiac lol. Too bad they had great concept cars. I currently have a 2004 9-5 ARC, but a fully loaded 2005 S60 2.5t i had before would get me compliments and people thought it was a 2010+ that had 60k miles at the most (it had 201k when it was totaled). People can easily guess my Saab's age although it has less miles. Honestly, it's like they were stuck in the late 90's BUT definitely had a modern interior if you don't count the 70's dash. Which I've been in a lot of cars, and that's the first feeling i got.. super advanced 70's.

[@AutoAutopsy]

Yeah I certainly wouldn't say the 2008+ cars were outdated, the 9-3 and NG 9-5 both look new by today's standards.

[@tylerswartz8671]

2008+ 9-3, 2010+ 9-5 and the 9-4 all looked good for their market and i would've said modern until 2016. Course the new maxima to me looks a decent bit like the ng 9-5...

[@alldone00]

Saab's mistake was not using "ReAxs" as a selling point. Not many cars had this technology in 2003 so they could have easily made 9-3's look like the safest production cars on the road if they had only let the world know about this technology. They certainly missed the boat on that one.

[@AutoAutopsy]

Yeah, it’s really a very little known feature :(

[@9some]

luuuv passive rear steering

[@AutoAutopsy]

yeee

[@brabus5775]

9-3 1.8 linear have reaxs ?

[@AutoAutopsy]

All FWD NG 9-3’s have it.

[@SchwinnStraight8]

My 07 2.0t Sportcombi the REAXS system is noticeable when driving aggressively, Others tires are squealing with understeer and SAABrina just hugs even with sudden braking or power application. So YES the system IS noticeable but only by driving it hard.

[@AutoAutopsy]

I agree :)

[@kuraryuX]

Useful as fuck! This shit took a 70 mph turn...my boosted Acura rsx type S couldn't do it!

[@AutoAutopsy]

Nice!

[@candykendrick3530]

🤣😂u know what u should do? Make a video of how you fell head over hills in love with the Saab vehicles 😆because you love those car's😉a Saab is the absolute love of your life! 😂tell us the moment u fell in love with the Saab and when u first drove it 😁they are nice car's I could see you really liking it I can't wait to hear this story, as for your question I think it's very useful yeah 👍

[@AutoAutopsy]

I already made a video on that, it's called "why did I buy a saab?"

[@user-lj4ds5rm7r]

My father had a saab 93 aero 2002 rwd

[@AutoAutopsy]

no saabs were rwd..

[@zachtong5985]

Since people spend time INSIDE a car not outside the 9-5 is definitely more comfortable and roomy.

[@AutoAutopsy]

This video isn't about the 9-5...?

[@brianrobinson5661]

Alarm keeps going off. Any ideas?

[@AutoAutopsy]

You'll have to be more specific; I'm not sure

[@keithsymons5708]

You may have a speed warning alarm on it can be taken off your display computer

[@pbutter237]

Sorry to burst your bubble, but Saab discontinued this feature only after two or three model years. The newer 93 models do not have ReAxs.

[@AutoAutopsy]

I don't think so, everywhere I read about it said 2003-2012, meaning every year of the new 9-3. Can you point me to where you found that information?

[@pbutter237]

When the new 93 came out, I was in the car business. I loved this car and did a lot or reading about it. I even got to take one home overnight while my antique Saab was in for service. I read up on the changes to new model years by picking up the dealer brochures and reading reviews online. I remember specifically reading that the ReAx system was dropped only two or three model years for either technical or cost issues. Most likely it was cost as GM typically reduces the standard options on a car the longer it is out on the market as it did with some Saturn models. So, I cannot cite a specific source without spending a day searching my old 93 library and/or the internet. If I find some time, maybe I will get back to you on this! 8^)

[@pbutter237]

If you are in the UK, the same 93 there may have had different standard equipment for the same model year. The 900s had differences in the US market compared to those sold in Europe for example.

[@waverunner7063]

To be honest my 2008 9-3 is one of the best handling front wheel drive cars and I attribute that partly to the ReAxs system. I have no proof my 9-3 has it but it feels, especially when corner on long ramps, like it can be pushed to high speeds.

[@markteague8889]

I owned a '95 Audi A6 FWD model for about 5 years. My 04 9-3 Aero may have a higher skid pad rating. But honestly, I preferred the handling characteristics of the A6 in normal highway driving conditions (clover leaf exits / entrances and such). I just always felt like the 9-3 was; perhaps, more unpredictable. It had more of a go-kart style of feel / feedback through the foot pedals, seat and steering column. The A6 felt more predictable in the sense that I *thought* I could determine where the traction limits were. And, the 95 A6 is a much larger touring sedan as compared to the 03-12 9-3 midsize sedan.

[@stevenlopez6682]

Hey

[@AutoAutopsy]

STEVE!!

[@williamhubbard114]

I have a oil leak and don't know what to do5

[@AutoAutopsy]

fix it.

[@urbanjentry222]

And this was Saab’s design before ford claimed to have “developed” there knuckle suspension

[@AutoAutopsy]

Interesting

[@dickn.ormous1064]

Citroen Zx had a suspension with very pronounced passive rear steering.

[@urbanjentry222]

Matsu Ma same setup or similar?

[@dickn.ormous1064]

The rear suspension set up was independent torsion bar with specially designed compliance bushes.For many years it was considered the best handing car of its segment.

[@Antoni13061953]

👍✌️🙏

[@AutoAutopsy]

:)

[@Ethankeenan02]

Money we'll spent id say if it means I can avoid a high speed collision and saves a life from an accident

[@AutoAutopsy]

good point!

[@charlescaltrop725]

Like many things that SAAB did this one for sure is something they did not sell to people buying the cars nor there was any effort from the dealers to sell. SAAB ads were really bad, in Mexico they advertised the car as it was only for rich and pompous people who liked the idea of - - "Looking down at people".

[@AutoAutopsy]

Yeah they could've done better advertising and showcasing their technologies :(

[@boogeymanb3748]

There is no diferences, in my opinión that technology does't gave better performance, but anyway SAAB must differentiated from competition if they had Focus on that technology..

[@AutoAutopsy]

Yeah, as I said, it's more for safety and control

[@jetjazz05]

I mean really... I think Saab failed in the 80s because of their small size and their inability to profit. They were sold in 89 to GM I believe, they kept making the 900 until 93 and in 94 implemented the new 900 which was based off a GM platform. If it wasn't for GM Saab would have been dead then realistically. Throughout ownership during GM's period they were always doing side projects that kind of scoffed at GM's requests, like for instance they were told to just use GM airbag tech in the 90s but they said no way and developed their own. In the GM lineup they were just butting heads with Cadillac, and GM didn't need to own so many overlapping companies, Chevy, Pontiac, Saab, and Saturn all had cars in the same segments which was really a bad idea from a money making standpoint. That's why they sold Saab (even though they wanted to liquidate but the fans were furious). Pontiac and Saturn however were liquidated, and actually Buick was spared because Buick sales in China are really high (highest of any GM product) so they kept it knowing China was about to explode in market size. After their sale to Spyker who wanted the distribution network and the factory abilities of Saab things didn't really go well, they hired Jason Castriota to design a hideous piece of shit concept car and poured a ton of money into R&D for a modern platform of their own, but after so much fighting from the Swedish government for securing money they finally said enough is enough and sold it AGAIN to "NEVS" who so far hasn't sold a single product and have abandoned the Saab name and are looking to sell electric cars to the Chinese government for use as taxis and such. They insist the Swedish engineers are pouring their Saab soul into the new NEVS vehicles, but it's clear they're just saying that to satiate the few real Saab fans left wondering what will happen at the Swedish factory.

[@AutoAutopsy]

Yeah, I've made 3 or 4 videos going over this stuff if you're interested lol

[@thexXxvictorxXx]

Jesse Crandle they didn't abandon the saab name, they couldn't use the name saab just because it was illegal for them.

[@Swedish_John_Wick]

U have to drive a 9-3 aero the chassi is much better.

[@AutoAutopsy]

They're both on the exact same chassis

[@Swedish_John_Wick]

Forget about it. Maybe in the us. In Sweden the aero has lowered chassi and harder shocks. Harder Bushings and swaybar. I had 9-3 whitout sportshassi and aero whit standard sportshassi. Differens like night and day.

[@AutoAutopsy]

Okay, that's different then what you were originally saying

[@Distracto76]

I have a 2003 9-3 Vector and my wife has a 2006 9-3 ARC. I can tell you that it is a very noticeable difference

[@per6605]

Everybody knows this existed! At least, it was big part of the marketing when the car was launched. Construction is similar to that of Alfa GTV (916), so it wasn't something new. Except that on Alfa, it is focused on making the car stable at high speeds, but on SAAB focused on making the car nimble and agile on curvy roads (something we have a lot of in Sweden). I had both cars at the same time. The Alfa Romeo is great at high speeds, but we ended up selling it because the SAAB was more fun to drive, and substantially easier to drive fast on twisty roads. Another difference: The Alfa could be somewhat "exciting" on winter roads when provoked. The SAAB on the other hand is quite predictable on both snow and ice, but can be quite treacherous on dirt roads, even when driving straight forward. I have absolutely no idea how this comes.

[@per6605]

Oh, I should maybe add: Definitely worth it! Without it we wouldn't have bought our 2nd SAAB 9-3!

[@AutoAutopsy]

i hadn't known it existed until after i bought mine lol

[@1aikane]

Seems to be not worth the microbenefit. I would rather have had interior control buttons that didn't fade

[@AutoAutopsy]

Blame GM for that one :(

[@shaheenfly]

It was definitely worth as the scientist would have been sitting and drinking coffee in those time. However, SAAB lovers and all car loving people should make moves and take initiatives to make a rebirth of Saab Cars. If KIA, Hyundai, Tata, Dacia, and othe Chinese cars can survive, it's a BIG INJUSTICE to kill Saab!

[@AutoAutopsy]

very much so!

[@h4mk3]

I think it is just marketing. The whole platform is identical with Cadillac BLS, Opel/Vauxhall Vectra, Fiat Croma and so on. Nothing special. A rear axle is always flexible this way due to rubber bushings.

[@AutoAutopsy]

It wasn’t just marketing, but go off!

[@h4mk3]

​@@AutoAutopsy Why doesn't the Cadillac have ReAxs with the identical chassis? Don't get me wrong, I love my 9-3 and I love your videos. But ReAxs is nothing special.

[@George241312]

Fuck its too late for saab to come back

[@AutoAutopsy]

[@Swedish_John_Wick]

Gm destroyed saab buy making saab use qeap plastis and cutting corners in quality. U know att one time gm vant saab to just rebage opel vectras. Thnak god saab didnt listen. Saab hade problems from time to time but always managed to get back somehow. But gm relly fuckt saab totally. Thas my personal opinion.

[@AutoAutopsy]

😔😔

[@paulwharton1850]

Interesting video. Unfortunately SAAB went down the toilet in Europe because BMW & Mercedes expanded, improved and made their model ranges more affordable coupled with vast dealer networks. Oh yeah, and also their use of GM parts and bits from various models didn't help their image ! They're also responsible for annihilating Volvo too. Please get rid of the much lower volume but still horrible back ground music. Thank you.

[@AutoAutopsy]

Background music is kept to a minimum and a very low volume; helps the video quality

[@tylerswartz8671]

Annihilating volvo...?

[@robsilveri8953]

Is this feature included on SC models or just SS ??

[@tlperdue99]

Get rid of that annoying background music!!

[@AutoAutopsy]

Haven't been using it in more recent videos :)

[@shadowwars1896]

This technology is not why so I went bankrupt. It went bankrupt because GM refused to hand over the patents to the technology to the new owners. Since they did not have the technology they did not have a car so they just had a name and that is it. GM is responsible for Saabs downfall

[@AutoAutopsy]

There's so man different opinions on this topic, it's really funny. I'm with you on it, although many would argue that Saab killed itself and GM saved them
