Chevrolet Corvette 2014

Chevrolet Corvette Z06 já tem preço: 78,995$
The 2015 Corvette Z06 offers performance that rivals the previous ZR1, so it's a tad surprising Chevrolet has announced the model will be priced from $78,995 for the coupe and $83,995 for the convertible.The model will be available in three trim levels and all will feature a supercharged 6.2-liter V8 engine that develops 650 bhp (485 kW) and 650 lb-ft (881 Nm) of torque. It can be connected to a seven-speed manual or an optional eight-speed automatic transmission.

If that's not impressive enough, buyers can add a $2,995 Carbon Fiber Ground Effects package which adds a functional carbon fiber front splitter, carbon fiber side skirts and a larger rear spoiler.

There's also a Z07 Performance Package which costs $7,995 and adds Brembo carbon ceramic-matrix brake rotors, Michelin Pilot Super Sport Cup tires, larger winglets and an adjustable rear spoiler.

So, what's new?

Following the industry trend - driven by ever lower emissions and greater performance - Chevy has slotted a new eight-speed automatic transmission in place of the old six-cog auto changer into the Stingray (and its heavy V8 trucks).

But shunning the same trend to use a ZF gearbox and just run their own shift program, like half a dozen carmakers, GM has actually designed and built this unit - codenamed GM 8L90 - itself. And it's a pretty tidy piece of kit, too. Despite having two more gears in the stack, the new box is several kilos lighter than the outgoing unit.

But I'll bet its change times aren't a patch on the best double clutch boxes...

Well, bet away. But you will lose almost every time. The GM box, which was benchmarked against the Porsche 911's PDK, doesn't just match that industry leading unit's swapping times - it also beats some of them. Plus it shaves another tenth off the 0-60mph time and quarter mile.

That's impressive - how does it drive?

The GM engineers have done their homework on this one. While you can swap the gears yourself with the paddles, if you just leave it in drive with the clever Performance Traction Management (PTM) engaged, it does a fine job of adding and subtracting gears itself according to the conditions.

On GM's Milford Proving Ground - a tarmac greatest hits of all the most savage corners in the world, including one they call ‘Toilet Bowl' - it quickly became clear that the eight-speed box makes an already great car even better, letting you concentrate on the track and enjoy the TG award-winning Stingray's fine handling.

The box has another party trick worth noting on the track. If you just pull on the downshift paddle and hold it on the way into a corner, the car will shift to the lowest gear the computer reckons it can handle. It doesn't sound like much, but when you are learning a new circuit it's a great feature. When you get to a corner, you can brake then just pull on the lever and aim for the apex, then power out.

What's it like on the road?

Pretty seamless. it never seems to be in a gear too high or low. Just instant response when you put your foot down. Likewise, it has none of the twin-clutch stutter coming out of junctions, so you can perfectly time your insertion into the traffic.

So is it better than the seven-speed manual?

For everyday road and track driving, yes. We'd completely understand if you chose the manual, though. It's not an outstanding changer but it does give you that complete control you can't get with any auto box.

When can I buy one?


The eight-speed auto box will be fitted to all 2015 model year Corvette Stingrays specified with an automatic. The same unit - plus a couple of coolers - will also be available in the new Z06 which debuts later this year. We can't wait.

2015 Chevy Corvette Z06 Performance Stats Released

The 2015 Chevy Corvette Z06 is coming, and it has already put the supercar world on notice with its 650 horsepower and 650 pound-feet of torque. Now, it claims some very important performance figures as among its feature set, too.

Headlining the new stats released today: 0-60 mph in just 2.95 seconds—when equipped with the 8-speed automatic transmission. We’ve driven this transmission in the standard Stingray, and found it to be a remarkable option--one that can, in some conditions, compete with and even beat Porsche’s PDK dual-clutch system.

If you should opt for the seven-speed manual in the 2015 Z06, however, you’ll ad 0.25 seconds to the 0-60 mph time, bringing it to 3.2 seconds total. That’s just the reality of rowing your own cogs these days.

At the drag strip, the Z06 is good for a 10.95-second run with the automatic, or an 11.2-second trip with the manual, both crossing the traps at 127 mph.

When it’s time to shut it down, the Z06 comes down from 60 mph in just 99.6 feet; in the turns, it can pull 1.2 g lateral acceleration—an improvement of 0.07 g over the previous Corvette best.

The 2015 Chevy Corvette Z06 goes on sale early next year with a base price of $78,995. Keep up with all of the latest Corvette news here.
