2015 Chevrolet Corvette Z06 Test Numbers




This isn't "A Closer Look". I don't have a second opinion, criticism or a different view. I simply have to include the performance numbers of a new Corvette Z06. Especially when they're blistering. 0-60 mph in 3.0 seconds. 3 seconds flat. From a front (mid) engine, RWD car with a starting price under $80,000. With a manual, this number drops to 3.2 seconds. The full acceleration numbers are:

0-30 mph (auto/manual): 1.3 sec/1.5 sec
0-40 mph (auto/manual): 1.7 sec/2.1 sec
0-50 mph (auto/manual): 2.3 sec/2.6 sec
0-60 mph (auto/manual): 3.0 sec/3.2 sec
0-70 mph (auto/manual): 3.8 sec/4.1 sec
0-80 mph (auto/manual): 4.7 sec/4.9 sec
0-90 mph (auto/manual): 5.6 sec/5.9 sec
0-100 mph (auto/manual): 6.8 sec/7.2 sec
1/4 mile (auto/manual): 11.1 sec @ 127 mph/11.3 sec @ 126 mph




It is worth mentioning that the numbers were recorded by different sources. Car and Driver tested the automatic and Motor Trend tested the manual but the gap makes sense so take that for what it's worth. Handling shouldn't be different between the manual and the auto. Braking from 60 mph to 0 took just 91 ft. Braking from 70 mph took 128 ft. That's just mind boggling compared to cars either magazine have been testing.

Motor Trend got 94 ft from 60 mph from a Porsche 918 Spyder. Average lateral g was 1.12 g for the 918 Spyder. For the Z06? 1.16 g. The only handling number that's lower for the Corvette is Motor Trend's figure eight which was 22.2 sec @ 1.06 g average for the 918 Spyder and 22.5 sec @ 0.98 g average. Remember, though, the Porsche has a 237 hp advantage. Randy Pobst said that the Corvette's chassis could use another 100 hp. With another hp, you can look for that figure eight to be even tighter. Still, the 22.5 sec time makes it the second fastest ever, only after the hyper fast 918 Spyder. 




The reviews from both magazines are filled with comments about it being incredibly fast, stable, and easy to drive. It comes with an automatic. It comes as a convertible without a performance penalty. For a purist, that's blasphemy. But as an accomplishment, it's astonishing. 

The only thing you could complain about is that it weighs 3,533 lb which is nudging 4 seater territory of this caliber but how can you complain when the numbers are that fast? I have recently learned that an electronic differential can be over 60 lb heavier than a Torsen limited slip differential because of all the clutches and motors (Source: Car and Driver on the Lexus RC F). Chevy also says that, with the third stage aero package, it produces more downforce than any other car they have ever tested including Porsche 911 Turbo S, Ferrari 458 and McLaren 12C and I'm sure the aero components add a few pounds. I would like it, though, if GM did a more focused version without the luxuries like heated and cooled seats, WiFi, and many others that I'm sure the Vette has.

The standard Corvette with the Z51 package already stunned me at Car and Driver's Lightning Lap 2014 with a lap time of just 2:53.8. I have no doubt that this car will be well within the 2:40's at next year's Lightning Lap, probably with a lap time in the 2:45 to 2:48 range. I can't wait to see it. Ford cannot come back with a new Ford GT soon enough! For full test reviews, here are links to tests done by Motor Trend (manual) and Car and Driver (auto).

Michelin Pilot Super Sports vs Firestone Firehawk Indy 500 - Street Review

I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track loads.…

Koenigsegg Gamera: 4 Seats, 4WD, 3 Cylinders, and 1700 hp

Meet the Koenigsegg Gamera. This car brings so many firsts, not just to Koenigsegg, but also to the entire automotive industry. For Koenigsegg, it is the first car to have 4 seats, the first to have 3 cylinders and the first to have all wheel drive. Koenigsegg calls it the world's first mega-GT (gran touring) car, and I think they're right. For the world, it brings the first four seater, mid-engine, hyper car. Koenigsegg says it wants to bring the "exciting performance traits of a mid-engine two-seater megacar with the practicalities of a four-seater car with more luggage space" so the experience can be shared with "family and friends." Clearly, I need better friends...

With 1,700 hp on tap, you are sure to impress those lucky enough to be your family and friends if you own one of those. Of course, a three cylinder engine with 1,700 hp is likely to have all the driveability and flexibility of a farm tractor so Koenigsegg doesn't rely on it for all the …

Bridgestone Potenza RE-71R Track Review

For better or for worse, I have heard and read so much about RE-71R's. Everyone swears by the grip but complains about the wear. Generally speaking, the pros are:

1. They grip as well or better than most R comps.
2. They don't wear as quickly as R comps if driven occasionally on the street.
3. They work better in the rain than R comps.

The cons were limited to overheating quickly when used on track (being an autocross tire) and wearing too fast on heavy cars like mine.

In the popular 200 TW category, they are faster than the popular Hankook RS-4's and BFGoodrich Rival S's according to published Tire Rack Tests. According to plenty of reviews, they are also faster than well established R comps like R888R's (which don't seem to work too well on heavy cars anyway) and the venerable NT01's. But I was still hesitant for a while until I talked to a tire tech support gentleman at Tire Rack who has gone faster on RE-71R's than NT01s. In a Mustang (his own, not…

Michelin PSS vs Firestone Indy 500 - Track Review

A couple of weeks ago, I posted my first impressions of Michelin's PSS vs Firestone Firehawk Indy 500 tires. I've run PSS's for several years on the Boss, but I'm trying the Indy 500's for the first time. In short, I was worried about the narrower tires (I was running 285/35/18 PSS but could only find the Indy 500 in 275/35/18) and tread squirm, but I was happy with them up to that point just driving on the street. I had the chance to drive on them for three track days now. So what were they like? After my first session, they made an impression that basically persisted for the rest of track sessions on them. Phenomenal, unmatched value. Now, if value is something that stands out above all else, it typically means the compromise between qualities you want and those you don't is less than ideal, but the value is attractive. This is no different. I'll start with the bad, which really boil down to two: ultimate grip and grip longevity.

Grip is noticeably lowe…
