Click the above image for 26 high-res photos of GT-R parts.

The new Nissan GT-R is an engineering playground. We hope to get our chance to play with it soon, but until then, we get pictures. Luckily, Nissan has released detailed images of the GT-R drivetrain and suspension. These reveal some of the alterations made in the GT-R design from prior models. One of the more significant changes is the placement of the transmission. The dual-clutch transmission and combination transfer case sit at the back of the car, coupled to the rear differential (that makes it a transfermissiondiffcase). It makes for more balanced weight distribution with the transmission, rear differential and transfer case counterbalancing the weight of the engine and front differential.

The turbochargers have also changed from Garrett units used in past GT-R models to IHI, a Japanese-owned company. The turbine housings (aka hot side) of the turbochargers are a combined casting with the engine exhaust manifolds. Most likely this is done to save space and for emissions reasons to ensure the catalytic converters are as close to the turbocharger outlets as possible. Each turbocharger is followed by two catalytic converters, making for a total of four. Two intercoolers are also installed, as opposed to one with two inlets, keeping the charged air for each bank of cylinders constantly separated. This is most likely done to ensure precise metering of air.

While staring at pictures can reveal a lot of information about the GT-R it does not provide much input into the control systems. The electronics integrated into the GT-R such as the drive-by-wire throttle bodies, dual-clutch automatic transmission and electronic controlled front differential have the potential for Nissan to create a traction control system beyond any other in existence. The potential is also there for the ATTESA all wheel drive system. In previous models it involved only feedback from wheel speed sensors, throttle position sensor and g-sensor, but this time around much more data is available to be fed into the computer controlling the torque split to the front wheels.

      Looks like the latest version of the Eclipse. Which looks like a poor mans Audi TT (gen 1). Not trying to troll here, but it just hit me.
      • 7 Years Ago
      In my mind Nissan has never been so much about inventing a technology first, it has always been about doing it better than anyone at half the price.
      Look at the old RB26dett mill from the previous GTR's
      straight six, cast iron block, no varriable valve timing.
      And yet it woudl make well over 1000hp if done right.
      4wd, 4ws, stability control, all done before, but never quite as famously.
      • 7 Years Ago
      the weight of cars keeps going higher and higher, also not in-love with the slushbox only option.
        • 7 Years Ago
        I think he means no clutch pedal and rowing through gears, which I agree. Pushing a paddle button seems to easy to me, reminds me of playing a video game or something. Just my opinion though.
      • 7 Years Ago
      About the transaxle, the Ferrari Daytona had it in 1968. So what year did the Corvette get the transaxle ?

      Nearsighted history, picking and choosing what you like.

      No Super Hicas in the GT-R.

      The transmission is made by Borg Warner. DSG . Similar setup to whats that car ? Bugatti Veryon ?

      Weight distribution is 53-54% front 47-46% rear.
        • 7 Years Ago
        Pontiac had an automatic transaxle in the early 60s.
        • 7 Years Ago
        http://www.vwvortex.com/artman/publish/bugatti_news/article_535.shtml

        BorgWarner DualTronic(TM), the company's wet-clutch and control-system technology for a new-concept automated transmission that was launched this year on the Audi TT 3.2 and VW Golf R32, is on the 2004 Bugatti 16.4 Veyron. The industry-first technology enables a manual transmission to evolve and perform like an automatic transmission, yet deliver vehicle fuel economy improvements over automatic transmissions.

        I'm not saying Chevy was the first, just saying Nissan didn't invent it(as some probably believe). I'm DEFINITELY not saying there is anything wrong with the set up, IMHO it's the best configuration there is - I'd prefer it over rear-mid engine.

        I had no idea so many cars used it in the past though, that's pretty cool.
      • 7 Years Ago
      95.5mm bore (same as VQ35 and VQ37)
      88.4 stroke (7mm more than the VQ35)

      We would call that a stroked engine. Bored would be when you increase the bore size.

      I think someone needs to read an automotive dictionary.
        • 7 Years Ago
        Fine:
        3.8L?

        Jesus, Nissan has increased the displacement of the VQ AGAIN.

        Freakin' truck motor.

        People crap on American car companies for just riding on displacement, but when BMW has gone from a 2.0L M3 to a 5.0L one and Nissan goes from a 2.6L Skyline to a 3.8L one, the arrow has to point a different direction.

        Also, that cutaway car is sexy, but it sure emphasizes how much drivetrain is in this car. Colin Chapman would not approve.

        And if you think that the difference between bore and stroke makes any impact on my argument, I think you didn't understand my point in the first place.
      • 7 Years Ago
      Everyone knows that the front-mid engine and rear-mid transaxle has been in the corvette for years right? just throwing that out there, as I haven't heard mention of it at all.
        • 7 Years Ago
        Does that surprise you at all? Japanese are great at what they do, copying that is.
        • 7 Years Ago
        Actually, Porsche had the rear drive tranaxle in it's 944 S-3 or 968 rear drive cars well before Chevrolet. In fact they were using the 6-speed Getrag manual tranny/tranaxle in the 92-95 968's, before going to the Box..in 1996.

        Rear Tranaxles have been utilized for some time. They do offer a better front/rear weight distribution.

        Remember copying is can be interpretted as flattering or flattery to the one being copied. :)
      • 7 Years Ago
      Even though Nissan has been marketing the GT-R against the 997 Turbo, I think the cars that the GT-R will compete face-to-face in real market are the new -- ...

      BMW M3, Audi RS4, and Mercedes AMG C63.

      I bet buyers who shop for these three cars will really consider the GT-R as a new (and competitive) choice to them.

      I will.
        • 7 Years Ago
        "..close in performance to a v8 m3."

        I agree the comparison is more apt, the Corvette is a sports car not a GT car. Why people continue to compare to the 'vette, I will never know.

        However, I'd imagine the GT-R will proabably slaughter an M3. Albeit, the M3 comes in at $10k cheaper and is more than enough for most people to handle.

        But if I could afford either, I'd go with the GT-R.
        • 7 Years Ago
        I'd take it over the M3 also. I'd like to say it depends on the mpg (because this vehicle clearly will get awful mpg), but I've had a stiffy for the Skyline for almost 15 years now, and I've never particularly liked the M3, so GT-R it is.
        • 7 Years Ago
        exactally

        in stock form it should be close in performance to a v8 m3
      • 7 Years Ago
      Transmission in the back, just like the vette.
        • 7 Years Ago
        This is comparable to the tempest in the same way as a fishing boat is to an aircraft carrier. They both float on water and have propellers so they should be the same thing right? The comparison to the vette and GTR is more apt. But then again, both of the cars are doing it simply because it is the best way to do so. I don't see what the problem with this is.
        • 7 Years Ago
        and the 944 too, iirc.
        • 7 Years Ago
        SW,

        The 1961-63 Tempest weighed 2,900lbs and could be purchased with an all-aluminum v-8. The tempest had a wheelbase of 112 in vs the GTR's 110 in. So yes, the GTR, weighing 1000lbs more would seem like an aircraft carrier in mass.

        This tempest had a rear-mounted transaxle (which is how it got brought up) with an innovative curved driveshaft. The enabled a perfect 50-50 weight distribution and this car was built nearly 60 years ago.

        Perhaps you should learn a little more about the 1961-63 tempest before you poo-poo it.
        • 7 Years Ago
        Yeah, that 1961 pontiac tempest was something. It was the last US production car to use the rear mounted transaxle until the corvette in 1997.

        • 7 Years Ago
        and like the
        Porsche 924, 928, 944, 968
        Mercedes W169
        Alfa Romeo Alfeta and GTV
        Lancia Aurelia (1. production car using transaxle 1950)
        Volvo, Pontiac, Ferrari, Skoda, Cadilac, Maserati etc etc.

        Tranny from Borg Warner USA
        (they do the DSG for VW... means Nissan used all that knowlege for their overhyped car)
        Suspension from Bilstein Germany...
        Brakes from brembo Italy

      • 7 Years Ago
      what does dual-clutch mean?
        • 7 Years Ago
        It means you never miss a gear.
      • 7 Years Ago
      What a retarded drivetrain.

      They could have put sandbags in the trunk, same effect, and it'd put more power to the ground.

      Front engine, rear transaxle, AWD. Alot of drawbacks(parasitic drivetrain loss, weight, complexity) to only one advantage -- weight distribution.

      Yes, this is the first car to feature such a setup, because no other car company is stupid enough to send power to the front wheels a farther distance than rear wheel power.

      E-Engine, 8-wheels, ---Path that power follows.
      ****RW***FW
      E-----8-----8

        • 7 Years Ago
        Yeah. Pretty funny. The front wheels are about 6 inches below the engine output shaft. And to get the power there, it has to go 10 feet back to the transaxle, then turn around and come 10 feet back to the front diff.

        I've seen less running gear in 1 ton trucks.
      • 7 Years Ago
      I have another one that the GTR stole an idea from,

      They stole the idea of an engine and 4 wheels. Now who would have thought that ....

      To those vette' fanbois get off your high horse about slanging the GTR before it has been released. If it is overhyped then it will definitely be slaughtered by the press and more importantly by the public.

      Also sadly all new performance and super cars are nowadays are have flappy shifts. Do not like it but that is the safe they get those fast 0- 100km speeds. Also the GTR will come in manual box later on.
        • 7 Years Ago
        There are no plans for the GT-R to come with a manual gearbox. It is dead to them....

        RIP in car leg workouts.

        I'm no Corvette fanboy, but I'm not over living this car until I drive it myself. Anyone who says that this car rewrites the super car book is full of crap, drive it first and then come back and write up a review. Though I won't discredit where credit is due, this car looks to be a bad ass.

      The three switches that have "R" and "off" are ridiculous.
        • 7 Years Ago
        You're complaining about switches? really?
