You are in the Nissan GT-R Forum. Your Host is claires
First Look: 2009 Nissan GT-R - Due for its much-anticipated unveiling at the 2007 Tokyo Auto Show, the 2009 Nissan GT-R will finally arrive in the U.S. next spring. Nothing will ever be the same again. (more)
A Lap of the Nurburgring in the 2009 Nissan GT-R - One of the primary performance objectives set forth by the Nissan GT-R's development team is to lap the Nürburgring's Nordschleife faster than a 997-based Porsche 911 Turbo. The 2009 Nissan GT-R had circled the famed circuit in 7 minutes and 55 seconds during endurance testing earlier in the year, trailing the 911 Turbo by 15 seconds. (more)
First Drive: 2009 Nissan GT-R (JDM Spec) - Unlike most supercars, the GT-R doesn't sit only 2 inches off the ground, so it's easy to slide into the driver seat. This is a Japanese-market car, so we're on the right-hand side, which makes everything feel awkward. The seat is firm and narrow, and the high center console gives the cabin a tight, cockpit-style feel. (more)
Full Test: 2009 Nissan GT-R (Japanese-Spec) - We know you want the numbers and we're not going to waste your time. Neither is Nissan. Its 2009 GT-R hits 60 mph in 3.3 seconds, quicker than the last Dodge Viper, Corvette Z06 and Porsche 911 Turbo we tested. (more)
Full Test: 2009 Nissan GT-R - Bottom Line:The GT-R delivers a rare combination of speed, agility and technological sophistication. It's a bit of a cold fish, but for $76K, we'll deal. (more)

Replying to: 240ka (Feb 15, 2008 4:00 pm) Also, I think in the 2011-2012 timeframe, Chevy is thinking about putting Corvette on a further diet, with the engine size set to 4.7L or so. This could bring the future Corvettes below 3000lbs. A 1000lb weight difference will put some pressure on the GT-R for sure. However, for the time being, the speed of the stock GT-R is nothing compared to what the GT-R is even more famous for: aftermarket tuning. With today's advances in tuning software, and Nissan's onboard computer prowess, it is unknown how much bolt-on power potential that engine has left in it. Intake/exhaust + reflash alone could get up to an instant 100-200hp. Do a turbo and intercooler swap? And you can easily double what a boosted engine puts out. There's plenty of R33s that were tuned to 1000hp/tq. And being AWD, all of that power goes straight to the pavement. If Nissan's launch control can hold it all in check, expect 0-60 in the high 2's and 1/4-mile in the sub-10's. Basically all GT-Rs are like a Lingenfelter with intake/exhaust restricitons holding them back. Remove any restrictions and let'er fly.

Replying to: trueteller (Feb 16, 2008 5:13 am) Nissas has already stated the GT-R doesnt need more power. weight redution is just about it. exhaust, intake, new intercoolers, up the boost. its all. remember the GT-R is putting out 520hp at the engine. it says alot about Chevy that they need 650hp and a car that only weighs 3200lbs to keep up with the field. they arent doing something right nissan has showed its not about weight. weight helps a car, and the corvette would be better if it had more weight b/c it would be able to put its power to the ground better.. its about balance. the GT-R out performs the 911 turbo and z06 and they both weight 400-700lbs less than the GT-R its not about weight. its about balance and putting power to the ground

Replying to: 240ka (Feb 16, 2008 9:42 am) It is about balance though, and that's what I was saying. If they lightned the engine, the car would lean back more on the drive wheels during launches. Less spin more power to the ground. It is about weight, and power and traction. All factors play into it. The GTR obviously has the traction to compensate for its weight. That's why more and more supercars are either going AWD or mid-engined. Or both. The best way to get 100 percent traction to the drive wheels is to drive all the wheels. Nissan's AWD just seems to work best. No power loss due to wheel spin. While a lighter GT-R would help, I'd rather not sacrifice the radio, doorlocks, or power windows. So if I owned one and wanted to go faster, I'd do an ECU reflash and filtercharger to try to get up to 100hp more. Just to make sure I stayed ahead of the ZR1 in the HP wars.

Replying to: trueteller (Feb 16, 2008 2:23 pm) the car cant put power to the ground b/c its so light and have too much power for the weight. so unless chevys going to make the vette mid engine then they need to add weight to the car to balance it. so i see the ZR-1 having the same problem as the z06 even with it having a new suspension and 20"rims. granted it has more weight on it but has gotten that much more power they dont need to lighten the engine, just put weight in the butt. thats why NIssan put the transmision at the back of the car to balance it with the engine ofcourse being in the frount well actaully id say the GT-R is mid engine. and look at what they have been able to do with 3800lbs. beat a 3100lbs z06 and a 3400lbs 911 turbo. but when you get into variants of course you lose things. look at the F430 Scuderia it doesnt have a radio. and can post times like or close to the enzo but i doubt cars such as a GT-R Spec V and Evolution will lack radios.. just geting differnt ext materials, no back seats, little carpeting, etc also i doubt Nissan is even thinking about the Corvette. i mean look. the Spec V and Evolution are giong after the Carrera GT and GT2 in the process. they've already smacked chevy up. besides Chevy is still competing with Ferrari theres no ferrari at the top of the list. just koenigseggs, porsches and zondas soon to be nissan. and with Nissan making this huge leap to performance where other mid engine cars are. Porsche is going to have to suffer defeat by the 911 having the engine in the butt or take the risk upseting consumers moving away from the beloved 911 platform and start using the cayman platform. b/c cars are getting insanely faster but i dont see Chevy being able to get up with NIssan or porsche if they dont go to mid engine at some point in time if they dont add weight. but of course you will have alot of upset vette customers but for the vette the answer isnt more power. the asnwer is more weight to balance the car

Replying to: 240ka (Feb 16, 2008 2:51 pm) The Corvette already has a near 50-50 weight distribution. The problem is, half the cars weight is over useless wheels. True, adding wieght to the back could give it a 60% rear bias, but the added weight will slow it down. If you take weight out of the front, you still get that 60% rear bias, so 60% of the weight is still over the rear tires, and you get the same traction as if it were a heavier car, without 'bogging' it down. Moving the engine to mid actually reinforces both of our points. If you removed weight from the front AND put it in the rear, then you might be able to get a 70% rear bias. I agree that would be the easiest way to speed the car up. But Corvette still has some potential left in it. The race against the airplane part is stupid, but the point gets across. Lingenfelter This is what they might be shooting for with the ZR1. Granted, this car has drag radials on it, but its still a special-edition tuned production Corvette. Indeed cars are getting insanely faster. The platform isn't always the problem. In this case its the technology. There are Porsches and Lambos and Audis out there with the same type of power and weight distribution. So why don't they go any faster? The AWD system on the Nissan is just better. I'm not sure how they do it, but they must have some computer/microchip geniuses working for them. Mitsubishi is similar. For a 300hp car the EVO X is freaking amazingly fast. Even though there are cars with similar weight distrbutions, having a computer programming edge over the competition is what makes cars like the EVO X and GT-R faster than anything twice as expensive. Porsche won't have to abandon their platform, and neither will Corvette. But they will have to figure out how to get as much grip as a GT-R, and soon.

Replying to: trueteller (Feb 16, 2008 6:43 pm) the Engine in the GT-R i believe is behind the front axle while its not that far behind i would consider it to be a front mid engine car. you are very right about the EVO while im not to fond of the EVO X. i liked the EVO 9 better. but the porsche limits are being shown with it being compared to the GT-R on base platforms. as well as the corvette z06 atleast. we'll see how the ZR-1 does but again the problem witht the Vette is that it cant put its power to the ground. thats the main problem with the car. more power isnt going to do anything for the car if there isnt enough weight. watch sooner or later the bar is going to be raised to the point that if porsche and chevy want to kleep their cars to the road they are going to have to find a way to make them stick to the ground. if chevy doesnt go AWD which they wont the only thing they can do is go with mid engine or front mid engine like the gt-r. just like porsche. Nissan alone will keep uping the ante to where a rear engine car isnt going to handle well enough it already doesnt against the GT-R. they already have the AWD they are going to have to go to the cayman platfrom in the future(mid engine) if they are going to try and keep up. im betting the corvette will either get heavier or become mid engine. or front mid engine.

Replying to: 240ka (Feb 17, 2008 12:22 am) Reverse-engineering is actually a very convenient philosophy. Wait until someone else has a good design, steal it, and make it cheaper and more reliable. If Porsche wanted to, they could take a good, hard look at what Nissan has done with their AYC and AWD, and copy it. That would bring the 911 back into the running. I doubt it has quite as much to do with where the engine is in the car. If that were the case, the Audi R8 would stomp them both. Its really just down to how fast the reaction time of the ECU can transfer power to the 4 wheels and react to changing stimuli to prevent wheelspin. Nissan and Mitsubishi seem to have the fastest processors in cars available today. Yeah, EVO 9 was a beautiful car. The X has plastic vomit all over the grille, the hood vents, the fake vents on the side, the interior, the engine bay. Its wretched build quality. But you can't argue about their electronic traction systems. They rock. I think the ZR1 might make up some of the difference in speed, but at a cost. The Lingenfelter I think was a $30-40K option over the base C5 corvette. The ZR1 will be around $100K. Wth the Lingenfelter, I think they lowered the rear axle ratio to 4.10, killing gas mileage, but that means they didn't have to add weight in the back. So yeah, it is more expensive to make a Vette go as fast, but it can be done.

Replying to: trueteller (Feb 17, 2008 4:47 am) AWD Vette This is a perfect example of Corvette reverse-engineering off of some GT-R ideas. That would make them both front-engined, AWD. They would both have roughly equal balance, but the Vette would be lighter and more powerful. This could get interesting. Its a constant game of one-upmanship, and there is never any permanent winner. Its just waiting until the next guy steals your ideas. |

Replying to: trueteller (Feb 17, 2008 4:47 am) nothing on the GT-R is a copy of the 911 turbo. absolutlely nothing. Nissan never needed to copy anyone. they just studied everything about the car to see what set it part from the others. but thats a bad term "reverse engineered." no ideas from the 911 turbo was stolen and used on the GT-R. Im sure the head of porsche bought a GT-R and is using it as a benchmark like nissan did with the 911 turbo. if they are smart they would. i agree with you on the vette comments. ii;d rather just get the ling vette and have even more powr than the zr-1. i like the zr-1's looks and at the same time i dont. it looks good in one glance and in another it looks like a hot wheels car. zr-1 looks like a kid designed it in a way to me. |

Replying to: 240ka (Feb 17, 2008 8:11 am) Similarly, the Corvette going AWD can only be a reaction to the GT-R. They have to be looking at specifics on the GT-R to reflect their own improvements. It is a quid-pro-quo environment. |
