2015 Corvette Z06 Clocks 0-60 in Less Than 3 Seconds!

Chevrolet has been putting the 2015 Corvette Z06 through its paces and have announced the initial performance numbers and we've got to say, they're impressive. When equipped with the 8L90 transmission that GM designed in-house, the 650hp, 6.2L LT4 delivers the Z06 from 0-60mph in just 2.95 seconds, while the 7-speed manual reaches 60mph in a very respectable 3.2 seconds.

While 0-60 is a good indicator of how easily a car can merge onto the highway, the great American yardstick of acceleration will always be 1/4-mile elapsed times and team Corvette didn't disappoint, claiming a 10.95-second time in the 8-speed with the 7-speed manual clocking a 11.2, both with identical 127mph trap speeds. Corvette has come a long way, it took a stock 1953 Vette 11 seconds just to hit 60mph!

2015 Z06 LT4 052814
We got a behind-the-scenes look at the LT4 and spoke to the engineers that developed the most powerful GM engine ever. With a supercharger that's more efficient that the LS9 V8 in the previous generation Corvette's top-of-the-line ZR1, the Z06 has a horsepower advantage at every engine speed. Combine that with a small frontal area for less aerodynamic drag on the top end and a quick-shifting automatic, it's no surprise that the Z06 is a 1/4-mile menace, but how does it stack up against some of the most quickest sports cars on the market?



Vehicle 0-60 1/4-mile e.t. MPH MSRP
2015 Chevrolet Corvette Z06 2.95 10.95 127 $78,995,
2014 Dodge Viper TA 3.3 11.3 129.3 $120,500 (est)
2014 Audi R8 3.2 11.3 125.8 $188,995
2014 Nissan GT-R Track Pack 2.7 11.0 125.1 $116,710
2014 Porsche 911 Turbo 2.6 10.9 123.7 $199,065

That's quite the list of competitors, but we all know that these cars are a lot more than just 1/4-mile times. It still shows that the Corvette brings a lot of performance to the track for a (relative) bargain, beating several AWD competitors that are way out of its price range. Then again, if its 1/4-mile times you're after, there are a lot of ways to go faster. To put that 11.95 e.t. in perspective, if you entered the Corvette in our Drag Week competition, it would have only been competitive in our two slowest classes. The quickest cars on Drag Week 2014 were hitting 60mph in less than 1 second.

Truly impressive to say the least. I assume the 10.95 ET was with street tires... Soooooo, if one were to do the same as the Hellcat tests by adding a set of drag radials???? YES, as Bob stated earlier, "Having it with the new A8 8 Paddle Shifter....... Priceless! ;)

Nice to see some performance numbers coming out. Now to wait for full test drives and additional data to back it up!

Here's some of GM's official press release:

"When it comes to braking performance, the Z06 can stop from 60 mph in only 99.6 feet. That’s the best braking performance of any production car GM has ever tested. Additionally, the Corvette Z06 achieves 1.2 g in lateral acceleration compared with the Corvette’s previous best 1.13 g.

The new Z06 is also the fastest production car ever tested at GM’s 2.9-mile Milford Road Course, beating the record set by the Corvette ZR1 by a full second.


All test results were achieved with Z06 coupes fitted with the Z07 Performance package, which adds Brembo carbon ceramic brake rotors and Michelin Pilot Sport Cup 2 tires. The Z07 package also features the most aggressive aerodynamic package available on the Corvette Z06, which delivers the most downforce of any production car GM has ever tested."

I wonder what braking and skid pad numbers a Z51 with Pilot Sport Cup tires would turn in? My bet is pretty darn close to what the Z07 did. Both of those measurements are very tire dependent.

Wow, That is impressive! John, I guess both of us were too conservative when guessing the 0-60 time. What a machine. Can't wait to get my hands on it!

Very impressive for sure. I wonder if the numbers would be much different with a non Z07. I don't know how to compare the pilot sport cup tires to the regular super sport.

Those 2.95 and 10.95 second figures...let's call it a 3.0 and 11.0 second car.

Oh wait, marketing called and said get that bad boy's 0-60 into the 2's and 1/4 mile in the 10's...even if it's only by an infinitesimal amount of time...HA!

Thinking getting the tires hooked will be the primary limiting factor/challenge for most real-world users.

You got that right! Even in my C6 Z06, with "only" (LOL) 505 HP/470 TQ, could spin the tires without even trying to 80 MPH. Realize the C7 Z's rears are one size wider, are better rubber, and the car has eLSD, but judicious application of the throttle will always be key...
I will need to go to "throttle modulation" class...

I guess my question about the A8 would be "How fast 0-60 in Manual mode"? Their tests were in Drive mode, correct?
Would it be as good (I assume not) but then how close to the Manual Stick? ie A8 Manual mode vs. Manual Stick

All very good questions. It's all going to be about TRACTION, TRACTION, TRACTION. I think I might have mentioned this a few months back. Outside temperature, air density and the quality of the track surface are going to play a major role as well. If traction does present itself as a major issue and all else fails, then one needs to consider going to the expense of an extra set of matching Z06 rear wheels and a set of drag radials if it's important enough. Personally, I've been wavering back and forth on the issue and question whether I want to get back into it on a much lower scale than before. We really have to ask ourselves the question of what we really want to do with our Z06's.

In response to Bob's question in regards to full auto or manual mode..... I'm not real sure if it's going to be all that critical taking into consideration of how broad the horsepower and torque curves are in the LT4. Unless, of course the transmission displays crisper shifts in manual and track modes using the paddle shifters with the traction control turned off. Plus I think snorman mentioned one time he leaves the starting line flashing the converter for a harder launch. But then, traction may become an issue under these conditions. Guess we'll have to wait and see.

I believe 1st gear in the A8 is around 4.56:1 and even with the, I believe 2.41:1 rear gears it's likely it'll be going through 2nd gear at 60.... Gear changes with the automatic won't matter as much because there won't be any break in power during the shifts. Not sure about the 7-speed manual and how far out you can stretch 1st gear.

Although the pedal is still to the floor, wouldn't torque management et al dial back the engine's output during the shift?
