2021 Mercedes S580 Mechanical Review // Tech I Didn't Know Existed!

[@admiralfloofz658]

Mercedes tech here. Had the opportunity to drive one of these a while ago (still havent broken down so we havent seen these in the shop yet). But all I can say is that this thing is on a level of its own. I have never in my life driven anything like it, its an experience you have to experience to understand. One thing Sarah forgot to mention that is really cool on these is that the whole instrumentcluster is 3D, which is especially cool if you have the nagivationscreen selected, feels like looking into the screen.

[@harbingertheheretic3541]

3:15 - Those dimples serve the same purpose under the car that they serve on the golf ball. They create a boundary layer of air around the surface, allowing for smoother airflow around that boundary layer. On the golf ball, that gives the ball greater aerodynamic efficiency to allow the ball to travel farther. On the underside of the car, it will allow the car to experience less drag due to the way that air is made to flow underneath it. The Ferrari F12 has air channels that run from the grille to the center of the hood, and from the upper-outer sections of the hood to the sides of the car just below the A pillars. Those channels help to create a similar aerodynamic boundary effect on the top & sides of the car.

[@Trifler500]

Mythbusters did an episode where they clad an entire car with dimpling to see if it improved the car's aerodynamics.

[@jaydub5515]

Didn't Bugatti add some of those on the roof of the Divo, or one of their other one-off or limited builds?

[@afcgeo882]

The new WRX actually has that texturing on the ugly wheel arches.

[@robertevans6481]

I remember a mithbusters show and they did this in clay on top of the car. Very interesting.

[@Chris-fo9rf]

[@alsnow3582]

There's a lot of tech in this car but the head-up display is something else. A great review Sarah!

[@garyworokevich2524]

Love the sparky things when you tap the chassis. I know I can't afford a MB, but seriously appreciate the crazy engineering. Absolutely love your way of describing a beautiful machine such as this. Ruffles at the bottom of your pants are neat and unusual.

[@DiscoR53]

The dimples act exactly like the surface of a golf ball for aerodynamics it actually smooths out the boundary layer air flow for sound reduction.

[@offroadaddiction2073]

I agree 100%, I was going to make the same comment

[@wilgarcia1]

Ya they are great on a curved surface, like vortex generators. Not sure how much of an improvement it is on a flat service. I bet they did the math though.

[@jasonbbb5000]

But will it improve my driving distance, pun intended 😉

[@tomy8339]

You beat me to it, I was going to say the same thing.

I've been working at an independent MBZ shop for 25 years. This is the kind of POS that will finally make me move on to something else in life. Recently bought a 2020 TRD Pro 4Runner because it's such a "dinosaur". I want a car to work for me...not the other way around. The mere thought of the conversations I will be forced to have with customers about these cars makes me want to retire right NOW! Thanks for the review Sarah!

[@oruwatching]

"2020 TRD Pro 4Runner" Well done! Should last the rest of your life. :-)

[@gottliebdee263]

Posts like this are so disingenuous. "I want a Fred Flintstone car", great - go by one. The only thing that is constant is change. Modern manufacturers are forced to make cars like this due to cost and regulation.

This is the first mechanical review ive seen and I love it! Im a diehard mercedes fan, but I never get to see a review of one of these newer cars from a mechanic's point of view. It was insightful, thanks!

[@Joe-co4sq]

The golf ball dimples are for aerodynamics. There's a video of The Myth Busters that tested that theory on a cars outer body panels and it was shockingly impressive. Definitely worth watching.

[@ivaneberle3972]

You're completely on the money giving it the lowest wrench score ever. I've logged a lot of miles in high- mileage examples of MB S550s as a professional driver. The massage feature kept me from having to visit a chiropractor in 80 hour weeks behind the wheel. There is a reason why these tend to be leased, and why they lose >$100K in value by the end of a lease. They are extremely fun to drive right up until they're not. Too often they've become so mechanically crippled that to fix the components only MB has the diagnostic workstation to reflash or reset, you would be way ahead by parting it out. So they stay broken. I'd wager 95% of the black car service MB sedans are limping along with some major feature or several being broken.

[@Ferretts89]

Golf ball pattern is for aerodynamics... Myth busters did an episode about it with successful results.

[@mostcom]

Did they use the Mercedes Benz?

[@jamesredman1263]

The panel dimpling: on a golf ball, it reduces overall air resistance. So I expect this application has the same purpose. The skinny antisway bar maintains more compliance on rough roads, but seems inadequate, yes. The difference in lateral resistance to body lean is taken care of by the "E-Active Body Control" system on a constantly adjusted thousanth-of-a-second analysis basis, per the MB site.

[@TivonSanders]

It's amazing how far car technology has come. With the Augmented Reality navigation, if the car has active assist technologies like lane assist, collision prevention controls, etc, it could teach you how to drive without an instructor in the car. Amazing car.

[@stephenmoxley3004]

Another great review, Sarah. I'm glad that you brought up the complexity and cost of servicing a vehicle like this. Lots of people don't figure that into their buying decision and end up having a heart attack when they take it in for service.

[@Tempsho]

That's why most people lease high end cars and dump them after a few years. Car companies still get their sales numbers, it's the 2nd or 3rd owner that's going to have a nightmare of a time maintaining them

[@Torsee]

It will be difficult for you to give up ICE technology, but some fine electric cars are here. Please spend a week, or so, with the Merc EQS 580 and compare it to the 580 in this most excellent video.

[@habsom1406]

Very interesting, informative, intelligent and sassy review. Rarely see reviews where the underside and the engineering is so closely scrutinised. Many valid and astute observations Sarah. Whoa all that plastic is scary and looks very cheap and flimsy like it won't last very long. Yeah Sarah sure will be challenging when diagnosing electrical gremlins in 20 years time! Had a friend with a 6 month old E320cdi and Mercedes could not pinpoint the fault so they ended up just replacing all the ECUs and a range of other components, crossing their fingers that they'd managed to rectify it.

[@rayschoch5882]

Mercedes engineering has been superlative for decades. But, as Sarah noted at a couple places in her review, service can be insanely expensive because some of the components are very difficult to access, and some require partial disassembly of other components before you can even get to them, not to mention the specialized tools needed for actual service. Finally, note that Mercedes is NEVER on anyone's list of "most reliable" vehicles. With a lot of TLC ($$), they can last a very long time, but the cost per mile can get ridiculous. No thank you, especially at this price point.

[@kirkchapman80]

Friends don't let Friends buy German

[@epbrown01]

Well, to be fair Mercedes-Benz made very reliable, durable cars up until the 90s, when leasing became the norm. Their customers don't need the cars to last as long, so they don't bother.

[@slasher9883]

If you have owned or worked on any Mercedes in the last 20 years you would know that the engineering has been anything but superlative. Lots of flashy, gimmicky tech for sure, but at the expense of getting the fundamental engineering right.

[@jdantigua1999]

I own an E Klasse and definitely a maintenance hog and I do the work myself using $300 of Mercedes specific tools for my car. LoL

[@rasch19785]

There is a difference between robust and reliable, both will last, one will feel the same after 20 yrs, the other wouldnt require alot of maintenance but will feel like it had t been maintained.. So

[@fresnokidsr]

Mercedes made a beautiful S class inside and out. I was really on the the edge of my seat for the wrench score.

Great review Sara. Thank you 😊 for talking about the Audio Systems between the Lexus and the Mercedes. It’s hard to find people that talk about the differences when it comes to audio. In most cases poor audio is a dealbreaker unless were speaking about an exotic car where performance is the up most concern

[@wesleycoulter3346]

You made me feel all kinds of warm inside. Talking about the seats.

[@cnorton1us]

Amazing amount of tech in this car, most of which seems to be designed to isolate the occupants from any driving sensations. Obviously, this isn't intended to be M-B's driver's car, nor is this the kind of car people would keep for many years and hundreds of thousands of miles. M-Bs in general are known to become money pits as they age, due in part to the expensive parts and all that complex engineering which requires mechanics to disassemble half the car to get at things that only require removing a few bolts on "lesser" cars. Great review, and it's nice to see a car like this reviewed from a more "regular person" reviewer than typical for something like this.

[@JayLepisto]

Wow, what a next level driving experience you conveyed from the front seat! All the info and comfort tech there will not be commonplace for years. However, I saw the most joy on your face when you found the pillow in the back seat. Loved that!

As said, the golf ball dimples increase aero dynamics, it can also be done to inlet manifolds to increase air flow and can now be found on fan blades, again to increase air flow and reduce noise.

[@eefneleman9564]

Hair New Year, best wishes, health and peace! The dimples in golfballs are supposedly for aerodynamic purposes: the air would cling less to the ball. The nuts or bolts in the ball joints look like Torx to me. Glad to hear the seats were... Pleasing. There's probably a separate cooling circuit for the e-motor.

[@dimkongtoranin3521]

One of the points that car reviewers fail to highlight when testing cars is RELIABILITY. This is clearly a time-dependent aspect, therefore difficult to estimate when testing a new car for a few hours or a few days. But it is also one of the most important points for those looking at reviews. This is precisely why many of us enjoy your videos and especially the sessions where you lift the cars and analyse them from below. When you show the bottom of the car, many are interested in the technology, but many also try to understand whether the quality of the materials and technical choices will allow the car to last for many years. A tip: you could introduce a score (Ants? Camels?) to estimate the reliability of the car. We all know Lexus are the most reliable cars, but these are beliefs developed over the years and they are not immutable. For example, many reviewers like the Lexus NX 2022 but argue that the Genesis GV70 is better. It would be interesting to see if Genesis is improving reliability and the GV70 can be expected to last as long as a Lexus NX or if it's just a nice car to keep for the first 70,000km.

The version with the 10⁰ rear steer makes these so easy to put on my hoist at work. Love these cars... depending on the version, there are over 110 individual modules. The ball joint nuts are technically single use and must be replaced every time they come off. The front anti roll bar end links bolt right through the upper knuckle... these will be an issue in the rust belt... tons of cool tech in this car too

The golf ball dents on the plastic shield is to artificially create low air pressure under the car at high speeds. It helps push the car lower at speed. Of course I just made all that up.

Amazing resolution on the camera aimed at your face while behind the wheel (and no, no pores were visible)

[@ToolsOutsideTheBox]

I’m sure you’re going to get a thousand different explanations for the dimples. My version is hopefully simpler. The dimples create less surface area for the wind to interact with. On a golf ball, the dimples help the ball go further, faster and straighter!
