Vs Motor Trend Z06 vs Nismo GTR

[Emu]

Z06 gets more and more confusing.

http://www.motortrend.com/roadtests..._gt_r_nismo_comparison/track_performance.html

When we overlaid the plots of the Z06 and GT-R’s best laps, we all sat back, briefly confused. Is the Nissan really that much faster at higher speeds? Does the Corvette really outgrip the GT-R that substantially through the long Turn 2? The data doesn’t lie. (We simultaneously record these laps with two different Vbox data loggers precisely to keep them honest.) But on both the front and back straights, the Nissan clearly had the legs on the Chevrolet. Gearing? Aerodynamics? Heat buildup? Meanwhile, the Corvette’s big Turn 2 cornering edge quickly degraded during subsequent laps. Was heat generation in its tires rocketing their pressures? And notice, too, Randy Pobst’s pause between Turns 4 and 5 in the Z06 (avoiding a time-eating gear shift) and his dramatically early braking before Turn 9 due to a lack of total confidence. Often comparison lapping days such as these leave us frustratingly short on time to unravel all the underlying puzzles. But we know for sure that despite all the back and forth in the speed graph, the GT-R quickly grabbed a small lead on the Corvette and held it all the way to its 280-foot advantage at the finish line.

USA says us....
gt-r >>z06
z06 >> 918
....gt-r >>>>>>>>>>>>>>>>>>918??

The only consistency shown thus far by the Z06 is in its ability to confuse people as regards its performance. It's becoming pretty clear that it has major heat soak issues with that tiny 1.7L blower, which saps power but it supposedly had a lot of downforce (which also reduced acceleration), yet it is significantly slower in the fastest corner, even with the MPSC2 tyres, which give it an clear advantage in lower speed turns.

I guess the Z06 was using its manual transmission.

What happened with the Z07 "record" at VIR now? hahaha

Would love to know how a 911 Turbo S would do against these 2 cars on this track. I am surprised about the GTR having faster speed at the end of the straights, considering the Z06 has much more power (650BHP compared to 600BHP)and torque (650lbft compared to 481lbft) and is about 330lb lighter. Very interesting conclusion!

Lose.

The Z06 is actually doing alright considering a manual transmission until between 5 and 6.

The rest of the data speaks volumes about the tyres on the two vehicles:

The Z06 was fastest at the mid point in nearly every corner but lost it on the straights in the second half of the lap and through the fast left-right transition at 7-8.

SC Heat soak might have cost the Z06 a lot of power. They should retest. Definitely not a good situation for the Z06. It's meant to be the purest track car out there. To lose performance due to cooling issues is unacceptable.

I wonder how fast the GTR would be with MPSC2s?

Yes, but how fast it would be if Turbo S can also equips with Cup 2 tires and make track-oriented set-up quite a bit, is it possible to outgun the NISMO?

 

[Bucketslash11]

looking at an everyday driver episode about the camaro Z/28 i relize that it has a lot of the same aero tricks as the Z06 EXCEPT it has 305 trofeo Rs on all 4 wheels

if this result does say anything it's that the gurney flap produces too much drag and without it it can't put the power down

then we get to the 305 trofeos, usually supercars have smaller front wheels to improve cornering but it sacrifices thight handling for grip from trofeos, judging by the aero result from this test it seems they are the biggest factor for fast lapimes for the Z/28

Never seen a Turbo S get anywhere near a Nismo GTR.

Sadly, no test between Turbo S and Nismo has been done yet. But we do have the times of Sport Auto with the latest GT-R which suggest that the Turbo S could be close to the Nismo.

991 Turbo S 1:08.70

GT-R Nismo: 1:35.51

991 Turbo S: 1:35.62

2014 Car&Driver lightening lap(VIR). The Turbo S is 1.8 sec slower than GT-R Nismo, but as it states in the article the lap time would easily have shrunk into under 2:50 if TS can wear semi-slick tires instead of its standard P Zero.

If you check the braking and lateral acceleration, the Porsche is actually cornering and braking harder (higher g values) but somehow loses slight speed to the Nissan on some of the corners and straights. The time difference of 0.11sec you can say as been virtually identical as any factor can make one of them go a little quicker or little slower, but on the days they were tested the Nissan has a marginal time advantage.

"Latest" GT-R (MY2014) did it in 1:11,2 min... thanks to the softer suspension-setup

they don't seem to mention the tyres the GT-R was wearing, maybe it's the same case as MT ZO6 vs nismo GT-R where the GT-R didn't use semi-slicks

Sport Auto is a very bad source to use for any Porsche comparison and the GT-R has historically never performed well at Laguna Seca. Also worth noting tyre difference.

 

[ajjers]

Just proves what we all know that the Z06's "time" at VIR is completely non representative.

Regarding tyres, the Dunlop and the MPSC2 perform similarly on the the GT3 on which they are both options.

Different Dunlop.

GT3 - Sport Max Race

GTR - SP Sport Maxx GT600 DSST

The Sport Maxx Race and Trofeo R are literally the only OEM tyres that can compete with the MPSC2.
