We've been waiting for this for years now. After endless scrutinizing and speculating, we've finally strapped our VBox data recorder into the C7 2014 Chevy Corvette Stingray Z51.

The C7 Corvette is powered by an all-new 6.2-liter V8 engine that features direct injection, cylinder deactivation and variable valve timing. They result in the Z51 package that is thumping out 460 horsepower and 465 pound-feet of torque. All of this power goes to fat, 285 series Michelin Pilot Super Sport ZP tires through a seven-speed manual transmission.

The old C6 Corvette (a 2009 Corvette Z51 in this case) also has a 6.2-liter V8, but it uses traditional fuel injection and only managed 430 hp and 436 lb-ft of torque with the Z51 package and sport exhaust. The old 'Vette also made do with a six-speed manual instead of the seven-speed found in the C7, though they have the same ratios in gears 1-6, so this shouldn't be an issue. And while the two cars share the same rear tire width, this 2009 Chevy Corvette Z51 was on 19-inch Goodyear Eagle F1 Supercar tires.

How much better did the Corvette get?

Handling
Slalom (mph): 72.8
Skid Pad Lateral Acceleration (g): 1.08 (1.07 w/ESC on)
RPM @ 70: 1,450

Comments:

Acceleration: Launch control (after several runs) did a respectable job of getting the car off the line but results in heavy wheelspin. A more calculated approach utilizing a 3,800-4,000 rpm engine speed produced the best results. Get the clutch out quickly and let the engine's massive torque push the car forward. Gearchanges are easy, quick and consistent. Engine sound is awesome at wide-open throttle, too.

Braking: Some softening of the brake pedal is apparent even during single-stop tests like this. This car (VIN 0026) has likely endured multiple instrumented tests in a few days. Still, the distance (93 feet) is stunning.

Handling:

Skid pad: Very easy to approach and sense the limit of front grip. Precise steering and no body roll provide ample confidence to drive right past the limit of grip. And with excellent balance and a big margin between the limit of grip and the limit of control, doing so is engaging.

Slalom: It's easy to drive the C7 very close to its limits with little practice. Every single run was within 0.35 second. There's probably a quicker slalom speed in the C7, but we ran out of time to refine the best technique. Even so, this car is very, very capable in this test.

Handling
Slalom (mph): 67.9
Skid Pad Lateral Acceleration (g): 0.95 (0.95 with ESC on)
RPM @ 70: 1,700

Comments:

Acceleration: Best launch: 3K rpm, clutch out quickly and pedal it until wheel speed matches vehicle speed, then wide-open-throttle to redline. Shifter feels great when slamming gears, not so great on the street.

Braking: Pedal feel isn't as immediate as I'd like. Some pedal fade on runs four through six.

Handling:

Skid pad: Incredible balance. Great communication at limit during steady-state cornering. Good grip. Stability control works extremely well in "performance driving" mode. Wide threshold and doesn't punish severely.

Slalom: Performance driving mode allows plenty of slip. Best run came with it on without triggering the system. Still, it's very good. Base 'Vette, even with Z51 package, isn't as confident as I'd like in transitions. Feels same as Z06, but not ZR1.

The manufacturer provided Edmunds these vehicles for the purposes of evaluation.

    How many braking runs did you guys manage to get 93 feet? Other sites are showing around 104 feet which seems more believable. Did they run a better brake compound in Detroit for you guys?

    Lots of people trashing the front end of the new car saying it does not look aggressive enough, and they have a right to their opinion, but after looking at the 09 front end next to the 14 I would say it is a great improvement and really ages the 09 significantly.

    The new one is uglier from every angle...

    So the acceleration numbers are about what I would expect, but way to go chevy on those braking and slalom number improvements! Those are HUGE improvements in a single generation. I'm sure alot of it is tires as Michelin has released some out of this world street tires in the last few years, but the car's got to take advantage of the stick. The c6 really upped the corvette's game, but man the C7 base model is really the first "everyman's supercar" I've seen. Good fuel economy, low maintenance costs, approachable entrance price. Wow, I'm actually going to have to go test drive a corvette at a showroom. Never said that before. P.s. Where else is this engine going to appear?
