Admiral Ackbar Yes, but right now is the perfect time to buy a g37/q40 (rwd please) as you can pick up 35-60k mile clean examples for $15k or less. A used Honda civic/corolla or a 328hp sport sedan for $100 bucks more a month in fuel and insurance? You only live once and if you're a car guy the answer is easy.

[@WarWolfAngel001]

So ideally what I got from this video is Infiniti focused in styling and the engine for the Q50 and the G37 was more of a well rounded car for it's time, being a sports luxury sedan with good quality for the time, simplistic engine bay yet still fairly powerful, etc. I love the Q50's look and hopefully the VR can hold up to reliability as it did replace the VQ which other than the water pump being a pain (they dont fail often though, they seem to last when you maintain the cooling system), the engine was fairly easy to work on if you have the mechanical ability. G37: more bang for the buck, good engine, owner can work on it with a little know how, timeless design (no other car looks like it), reliability, decent MPG and a good transmission (it really is, just.. the software is kinda stupid sometimes). Good sports sedan. Q50: newer look, new potent engine for tuning, reliability in question (it's only been around like 3 years?), more of a lease car unless you feel experienced and confident enough to own it and work on it. Probably more reliable then a BMW. New features. Decent MPG for what you're getting. Good Sports sedan. I'm more of a G37 guy. I own one and find it good to work on myself. And I guess I'm somewhat biased towards it because I do love the car. But I wont look at the Q50 as a non potential car to own as I feel I can learn to work on it and keep it running. Itll be more expensive to run it but to me, it's still a really good car. But I'll be honest.. I think that if I ever went Q, I'd get the 3.7 model as I already know the engine pretty well. Who knows, I should test drive and look at the VR before I make opinions on it. Great video btw!!!

[@speedkar99]

Thanks for your opinion as a G37 driver. My brother likes his.

[@clee6746]

Great video you made on comparing the two cars. I have the G37x and I prefer the simple set up. I believe in a long run, the twin turbos and the steering clutch in the Q could definitely be the sources of trouble. The cramped arrangement in the Q could also be troublesome, not all mechanics are like you with a lot of experience and if they have to take off a lot of components to get the source of trouble, chances are they would mess up along the way and ended up causing more problems. Usually the owner will not be able to prove that and eventually the owner will be paying for the mistakes.

[@speedkar99]

I agree. I'd take the naturally aspirated engine for it's simplicity long term.

[@TheCamaro1987]

Wow. I've driven my 6MT G37 from 110K to 236k and this video really makes me see why I consider my 37 to be easy(ish) to work on. Hope to see the VR in the new Z for sure!

[@kuro4321]

I have a 1996 I30 with the bulletproof VQ30 engine. So easy to do the maintenance yourself. It would be a sad day when I have to say goodbye to this engine seeing all these newer designs. Even the Nissan mechanics hates these newer set ups. You should start a rating system 1 to 10 on ease of maintenance for the cars you review. Great job on all of them!

[@speedkar99]

Thanks. Maxima with the OG VQ are good reliable cars

[@Kyle-qc2vn]

Your mechanical reviews are enjoyable. I have the same 2013 G and they're reliable, fun to drive, good bang for the buck. Reading alot of comments that the newer Q has less horses. The amount it lost in horses was gained back in torque. I test drove one and it feels faster 0-60, but decided to keep the G anyway

[@speedkar99]

They are the same underneath. Can't stand the interiors though

I really like the styling on modernness (kinda) of the q50. Definitely prefer the power of that naturally aspirated V6 in the G37 but the engine inside the Q50 is pretty fun.

Idk why they decided to change to a small less powerful engine 😣. Seeing how compact the new Q50 engine bay is I'll buy a 300ZX TT before the new Q50 😉

The v6 TT is detuned to 300HP so they could sell a pricier 400HP version

[@M56x11]

I've been driving Infiniti's for over a decade. I personally love the brand. I actually had the G37 and owned a Q50's without the turbo's. And never realized the mechanic difference. This was an outstanding informative video. Thanks for taking the time to do it. I learned a lot. I agree with the comments of the interior. Infiniti needs to pick it up or they are going to loose customer's. Which is happening if you looks at overall sales. Again, good job!!

[@speedkar99]

Thanks and I agree, Infiniti has alot of work to do. This Q50 is still the 10-15 year old car underneath besides the engine.

[@chriss4169]

As a G coupe owner who recently did the valve cover replacement and had the engine half apart, and recently tore down the interior when doing a double din and repainted most of the interior, I still love my G. Put about 5k miles a year on it, its garaged.... it is timeless. Was recently tempted to pick up a Q and maybe one day I will but looking at the engine, it makes me think twice.. The G is timeless and still a very, very fun car. Just wish it had push to start and may do a suspension upgrade in the spring. Car has 110k miles on it now. Have had it for nearly 14 years. On a side note, was looking at some of the Lexus a few years ago.. 80k for some of them and you know what, I said this looks worse than my G. It's going to be hard to get me to go buy something new. It really is. Although I do like the iPace and even the Murano.

[@speedkar99]

Great to hear from another owner. I guess most G35/G37 owners get bored or tired of repairs and eventually give in after enjoying the car for the first 10 years or so.

[@chriss4169]

speedkar99 I guess it depends how many miles you put on it a year. I have found them to be pretty reliable though. (Knock on wood). I mean they have their quirks like the drivers side rip tear that needs reupholstering over the years and the valve covers eventually all go on these engines but other than that just a battery. But yeah I can see people wanting the newer tech and nicer gauges and fancier interior if you will but ehhh even when the day comes that the new “daily driver” comes wishing will probably be a Jeep Murano or IPace the G will always have a parking spot in the garage or driveway. Glad to see you have a love of the G and Q series as well. They are and always will be a very nice car. Happy New Year!

Love the video. My 2011 G37 just hit 100,000 miles, and being in south texas there isn't much rust at all. In my experience (F150 EcoBoost) turbos are dramatic failure points. I noticed the Q50 is an S model. Did they stop upgrading the brakes to the larger rotors and 4 piston front, 2 piston rear calipers on those models? Anyway, thanks for the video.

[@speedkar99]

I'm not sure what the S means anymore...I thought it would include the drive by wire steering Infiniti had but this seemed pretty basic to me.

[@blicce9597]

So from all the comments and your input the G37 is better engine wise, reliability and long term. What about the Q50 early models with the same 3.7 L engine? It’s the same as the G?

[@speedkar99]

Yes. Same. If you can stand that interior.

[@KO-pk7df]

The older ones for sure. I used to have a 78 280Z 2+2 that was wonderful and so easy to work on. The service manual I bought with it was incredible. At 188k miles I sold it to an aircraft mechanic who wanted it, surprise-surprise I wish I had never sold it. My son has a 2005 G35 Coupe 2-WD that is a great car but not looking forward to changing that water pump when the day comes! I believe the older ones are better quality and reasonable to maintain by the owner.

[@toolongwidth]

I haven't read all comments but I rather the VQ37VHR. So what I get from your video is if you like the Q50 styling but you want to work on the car yourself go with earlier versions of the Q50.

[@aeroman5239]

From the comments, I can only fathom the "hate" for the Q50 (also Q60) with the VR30 engine is because you don't own/lease/drive one. Properly modified (primarily consisting of an Ecutek tune, FI exhaust, and AMS heat exchanger upgrades), my '17 Q60 Red Sport AWD puts down just under 450 WHP & just over 500 WTQ w/93 octane pump gas on a DynoJet AWD dyno. Real-world performance with a 0-60 at just over 4 seconds, again on 93 octane pump gas. I've about burned-down the crappy Dunlop RFTs that came equipped from factory (weight of the OEM wheel & tire? 62 lbs!), so handling will only get better in the future with the installation of a set of lw wheels & tires. As for servicing, I perform my own oil & filter changes - installed AMS intakes, FI exhaust, Mishimoto CC, Stillen RSB, and ST BBK by myself. If you un-bolt and push-aside the ICs, you can access the coil packs and spark plugs. when needed. At almost 25k miles, my VR30 burns no oil between oil changes, w/5k OCIs. With the addition of a Flex-fuel kit, an AMS LPFP & HPFP, and Nostrum FI., the VR30 can relaibly perform on corn fuel (E85), which can get the output closer to 550 WHP/WTQ, 0-60 under 4 seconds, and the 1/4 mile in the low 11s. Not too shabby in my book...

Totally agreed. I have a red sport 400 as well and I love how the video says that the horsepower is only 300. Sure, if you want to compare the BASE 3.0 t Q50 to the g37 but you should at least state the full facts. The top model Q50 has 400hp out of the box. And also, the VR series is not just about more power, it's also a much smoother engine. I've owned a g37 and a 350Z so I'm no stranger to Nissan/Infiniti and I loved them all, but I just hate it when videos don't fully disclose everything. The only thing I hear in this video and comments is the turbos are not going to be reliable so get the g37....yah great analysis. Here's a wake-up call, most cars have turbos today. Deal with it or keep buying old cars that were naturally aspirated. I'm good with whatever you prefer but again, just state all the facts so the video is informative.

Man thanks for that in-depth review, man that q does looks like a spaghetti nightmare. I do like the simpler N/A larger engines over the turbo small engines. Having own a turbo'd engine car in the past and dealing with daily maintenance such as oil change and other thing associated with dealing with turbos to me wasn't worth the trouble and with my driving dynamics don't see the benefits fuel economy wise. I'm the kind of person that do my own repairs. I like cars that I can get access to components in the engine bay. Worked on older Hondas, Nissans and Toyotas. I've had toyotas in the past and virtually no issues, got a 350z and then a G37. Maintenance level is more on my speed. With prior experience with VQ's I knew the G37 was good for me. This VR30DTT sounds good and may make good numbers in the 400hp version but I can't imagine this thing 5 to 7 years down the road used having to replace stuff. But yah for me G37. unless it's the Q50 with the 3.7 liter.

G37/Q40 for the daily driving, Q50 for the weekend driving/backup car. But for even less headache, pick up a G20, preferably the P10 chassis.

[@speedkar99]

Q40 😏

[@1uch1n11]

got an M37 and I hope i keep it until they outlaw premium gas

[@danhg3885]

Great review of both cars. Really enjoy your detailed explanations and time to look at almost everything. I agree with you 100% the twin turbo is a mess. I believe the Q50t will be a major money and time sink once it gets some age. I feel for the folks buying a used one thinking it’s a good deal. It’s a shame they engineered such a poor design for maintenance. Guess longevity and durability are no longer a priority. The old G likely sounds and drives better anyway.

[@speedkar99]

Thanks for your feedback! I wouldn't say the Q50 is poorly engineered, it's just poorly implemented. Hopefully the VR engine is reliable enough not to need too much work.

[@danhg3885]

I’m not knocking the engineering chops it took to jam all the plumbing and equipment to manage and feed two turbos in a compact form factor. I emphasize it’s a poor design from the perspective of maintenance and having to work on the car after manufacture. It’s almost as they have the expectation if there’s a problem you just replace the engine as an assembly. Guess time will tell.

To be honest the AWD system had alot of grip when I drove it

[@wolfguard1180]

Q50 with the 3.7 sport option is the best I think.

[@speedkar99]

The 2014-5 offered it with the 3.7. Maybe it's a good value ....to me it's still not in the league of where a luxury car should be....

[@147NITRO]

Q50 hybrid the best one.. fast, good gas milage, most reliable.

[@speedkar99]

Good idea...but it's probably more complex than the twin turbo

[@147NITRO]

speedkar99 hybrids are simple dgearbox invertor batteries all of them durable , + those cars are only 2014-2018 they are not that old to have problems.

[@kevinknotts6337]

I like the power and potential of the turbo but there’s just way too much going on in that engine bay. I would lean towards the 3.7 engine. Also I’m still not sold on direct injection engines yet due to carbon buildup. How have the turbo engines been holding up?

[@thmqpgap]

Good video. Very knowledgeable about these cars. I’d take the G37 before the Q50. Too complicated, can’t even service it yourself

[@speedkar99]

You can service it yourself But you need to have alot of coolant handy!!!

[@bennett4881]

Owning the VR30 looks like it could potentially become a financial nightmare, unlike the VQ37. No?

[@danhg3885]

Bennett Deering I think they must have hired a few Mercedes or BMW engineers to help. It will be a disaster once it’s about six years old.

[@nathanpendleton9733]

Coming from an enthusiast standpoint, I'm going to have to go Q50. The tuning potential alone is enough to go Q50. To get the same power out of the G it's going to cost ya a ton of $$$$. Just a simple tune on the Q is going to net ya more than +75hp! Cant beat the twins!

[@speedkar99]

Q with the VQ37?

[@joeferreira1971]

Why do people like you compare the g37 to the BASE 3.0T and then say the g37 has more power? That's either lazy reporting or you just don't care to inform your viewers of the facts. The Q50 base 3.0t makes 300hp but the red sport 400 makes 400hp. That's alot more than the g37 which only had the one engine choice. I've owned both cars and love them both. Not here to compare but just want to hear the facts presented. A good review discloses exactly what you're comparing....

[@michaelc.6306]

[@adamrichardson2227]

Seems a bit of a waste to design a whole engine like this to get the same stock HP numbers as the VG30DETT, which was already reliable, powerful and well designed. 400HP variants aside, I don't see how this is 30 years ahead of the VG30DETT, especially when looking at the packaging. What am I missing?

[@speedkar99]

They haven't come that far in many years. The G35 cannot be beat

[@seb5945]

I got a G37. I've driven both Q50 with 3.7 and 3.0T. I don't like the Q at all, it feels so cheap inside. It also lacks both steering(EPS) and road feel(soft suspension). The worst among the 3 is the 3.0T. Not only it feels all round numb, it also has the added benefit of turbo lag.

[@speedkar99]

Is it at least faster?

[@seb5945]

@@speedkar99 Red Sport will be definitely faster. The regular 3.0T is 30hp less than what the 3.7 makes.

[@pullingpuppetstrings3826]

@@seb5945 3.0 T is actually 330 hp stock not 300. Dynos have shown this time and time again. So stock 3.0t is not slower than stock 3.7. Also the redsport is just the 3.0 with +4 psi of boost and an extra water pump so there’s really no difference between them after a cheap jb4 install both 3.0t models are identical. 3.7 is slow but reliable.

Thanks for the great comparison! Damn that Q50 honestly looks like a nightmare to work on under the hood, the thought of facing this 6:43 before needing to do anything around the engine is nightmare inducing haha. Perhaps a car meant to be leased rather than tinkered with in your garage. Any thoughts on the G35 vs G37?

[@speedkar99]

The G37 is a refined G35. Fixed most of the reliability issues but made the car slightly less raw and fun.

[@freds7988]

Thank you for your excellent videos Sir! I am living in France and I am impressed to see how the salt attacks all metal parts even in the engine bay ! I used to spray a mix of diesel and motor oil on all engine parts (of course not on hot parts nor on the belts !) before winter season to avoid this .

[@speedkar99]

Salt is a killer here. It's because everyone keeps getting sued for slip and fall incidents we have it everywhere.

@@speedkar99 Compounded by the fact these cars sound like they're about to disintegrate when you rev them out. I have one but you need to learn how to properly beat them to have fun, because the fun zone is 3.5k-7.5k rpm. To that extent, I almost prefer my old vq35de maxima overall, because of the smoother less jerky feeling engine. I do think the vq37vhr is a fun, special engine, but it's not a particularly good one.

[@BigHeadClan]

If it was a lease I'd snag a Q50, if I had to own the car for 10 years than the G37 would get my money and I'd just tune it for more power. Really Infiniti just needed to invest like $150-$250 extra into the car to drop some of the cheaper parts clean up the wiring. Well fingers crossed for the 2021 Redesign.
