Ferrari 458 Italia vs Nissan GT-R

^indeed
458 Italia 1:36.22
GT-R MK2 1:36.35
GT-R MK3 1:36.63
all lap times same driver same conditions, that counts (R.Pobst/Mazda Raceway Laguna Seca)

Now this veredict it´s 100% correct...

@Sal30
Yes, but like any maunfacturer time it is not comparable to a magazine test where often only 1 or 2 timed laps are available!

F355,

Nissan has video proof of all their runs and times at nurburgring so it is not a claim but PROOF. The GT2RS's 7:18 is a CLAIM by porsche because there is no proof of their run by video or 3rd party verifier. get it?

err, can I just point out something, the GT-R is less than half the price of the 458 before you Fan boys get too het up!!

@Hey!

GT-R MkII was tested at 7:34 on Nordschleife, 7:24.22 is only factory claim.

At Streets of Willow the comparison mixes times by journalist / pro Randy Pobst:
1:22.30 / _:. 458
1:23.87 / _:. ZR1
_:. / 1:20.25 GT-R MkII
1:24.28 / 1:20.43 Z06 Z07 Package
1:25.09 / _:. GT-R MkI

So the GT-R MkII beats the 458 only on 2 of 8 tracks and never with 2011 tires.

I think these cars are just at the same level! Half of the track times are for GTR, half for 458.
In straight line speed, consider hp output difference... and it clear are both on the same plain. It's disinformation to say 458 is noticeably faster when the total difference are just 5 points!

Gearing only helps so much. If fact, tight gearing doesn't really make a car accelerate any faster so much as it makes the car accelerate near its peak rate more often.

The peak force that the GT-R can propel itself with at a given speed is determined by its power at that speed. Peak power is 520, so at 100 mph the best amount of force a GT-R could hope for is 1950 lb.

Now let's go to some other car with wider gearing, like the Viper SRT-10. At 100 mph, the best it could hope for is 1912 lb of force. But the gearing is long, so the power might be far from peak power, lets say 450 hp. This means force is at 1688 lb.

For the GT-R, there is .51 g of acceleration (without drag). For the Viper, even though it's down by 60 hp, the acceleration is .49 g. The GT-R's weight really hurts it.

"That's only if you're lucky and someone doesn't happen to be there, even if it's a .1% chance."

In that case.. I'd take the ditch. If you had a 160 mile daily drive through twisitng rural roads with 35mph limit and you refused to go over the limit then you wouldnt get any work done because you'd be driving all day. Only people that do the speed limit here is tourists. Christ man.. you sound like a granny.

You dont think that if they geared the GTR for a 180mph top speed that it would post better acceleration numbers after 60mph?

Only things you risk hurting by running public roads here is yourself, animals or a tree lol.

I guess I can't convince you to stop, but the only place I've ever been over the speed limit is on a race track, and it's going to stay that way (unless I go to Germany).

The GTR has pretty good power, 520bhp is formidable.

But it's also larger than most cars, so the drag is bigger, and there is also the weight.

As far as gearing goes, I looked at the 2007, and it can't reach 200 mph with stock gears. The car has some nice ratios for a race track.

@E

While there are certainly some dumb people out there.. thats the most common encounter with street cars.

I live in a rural area without any tracks so most races get run on twisting mountain roads that are abandon late at night. I've been doing it for 15 years and never have I or anyone else around me had a serious accident. Mainly because we dont act like idiots and race around crowded roads. The roads we run go through the national forest which has no houses and is empty during the middle of the night. Our "drag strip" is a 3 mile stretch of rural public road without any houses or turn offs. Only things you risk hurting by running public roads here is yourself, animals or a tree lol.

The GTR has pretty good power, 520bhp is formidable. I think it would benefit from a different gear ratio that would cut off some top speed to add acceleration. But I guess the 200mph car bragging rights come at the cost of acceleration in this case.

On the part of German highways without speed limit this is legal and pretty safe because everybody pays attention - well, almost. The rate of heavy accidents is comparable to Swiss highways with a 120 kph limit where people tend to fall asleep.

Most real world encounters your going to have are high speed freeway runs. You'll be taking off from freeway speeds on a strait road and going until you run out of room and in that situation the GTR is gonna get creamed by the 458.

That's only if you're dumb and if you could care less about the law or safety.

Everyone else will go to a drag strip or race track.

As for why the car is like that, it's heavy and not all that powerful. Power vs drag is what determines high speed acceleration.

Look at the difference in acceleration from 0-200. Thats always been the GTR's pitfall.. acceleration after 100mph doesnt compare with the supercars.

The GTR acceleration drops off rapidly after 60mph. It traps at a pretty low speed considering its fast 1/4 mile time. I think the blistering launch off the line is the main reason it gets such good numbers. From a roll I have a feeling cars it should beat would easily walk away from it.

The old GTR was about 25 seconds slower to 300kmh than most supercars and that is a conisderable difference. I keep waiting to see a 0-300 tests to see how much the new one has improved.

Bottom line is that without a standing start the GTR losses a lot of its glory. Strait line acceleration isnt that great without the AWD launch.

Wonder why the acceleration is so poor without the launch? Is it a power/weight issue? It has a good amount of power and should accelerate better from a roll than it does.

Streets of Willow, times by journalist / pro Randy Pobst:
1:23.87 / _:. ZR1
_:. / 1:20.25 GT-R MkII
1:24.28 / 1:20.43 Z06 Carbon
1:25.09 / _:. GT-R MkI

Looks like the GT-R MkII is between ZR1 and Z06 Carbon in reality.

On the other tracks GT-R MkII was 0.7% faster in average than MkI.
According to Nissan the difference between MkI and II on Nordschleife is 0.6%.

ups, I can't find it.. but it was a low 1:24... or maybe I've mistaken the 1:25.1 from the '09 GT-R...

Mike B, what time did the journalist with the GT-R MkII at streets of willow?

Let see:

Nurburgring GP: 2s slower despite semislicks

Streets of willow: 2s slower (comparing jorunalist time vs joournalist time, the pro who set that 1:20 also got a Mustang GT500 faster than a ZR1)

Hockenheimring short: simelicks were used by the GT-R and the 458 wasn't driven at full, like most Ferrari laptimes on sportauto

Nring is mfr vs independent and top gear is standing start and all media hype.

Is that rough explanation enough? if not read to the post below by F355.

Actually, GT-R is faster on the race tracks, and it's the only thing that counts.
