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.

Braking

 60-0 (ft): 93

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.

With the first run of 1,000 2014 C7 Corvette Stingrays making their way to select dealerships across the country, General Motors has confirmed to GTspirit that there is currently a six-month waiting list for the Corvette Stingray, making them late for the holidays.
Customers are paying premiums from $5,000 all the way up to $20,000 to be moved to the top of the waiting list, with demand even coming from Europe, Asia and the Middle East.
Only 900 out of the 3,000-plus Chevrolet dealerships in the U.S. are getting the opportunity to sell the new Corvette, after GM announced only dealers that had sold at least four Corvettes in 2012 would get the opportunity to sell the car.

One of the big news items on the 2014 Corvette Stingray is Chevrolet’s attempt – and success – in improving interior quality. However, the improvements to the Corvette go much deeper than that thanks to a $131 million investment at the Corvette’s Bowling Green Assembly Plant. That money has gone into producing subassemblies with 25% more precision and efficiency with a three-dimensional laser-based inspection system for quality control.


 
Almost 40% of the investment went to a new in-house shop that develops the new aluminum frame that is 99 pounds lighter and 57% stiffer than the C6’s.
 
Plant manager Dave Tatman says, “The new aluminum-welding process enabled us to make the frame lighter and stiffer, improving performance and driving confidence. Measuring 100 points on every frame reduces the chance for unwanted squeaks and rattles that would distract from the driving experience.” Convertibles don’t require any additional structural reinforcement.
 


The frame goes beyond being lighter – its five aluminum segments are connected by advanced joining processes and inspection methods that make for a stronger and more dimensionally accurate frame. A high-speed drill extrudes part of the frame to allow 188 Flowdrill-machined fasteners to join closed sections of varying thickness and mass based on the structural requirements of each section; a complementary structural adhesive is also used, both eliminating the need for post-assembly machining.



An aluminum resistance spot-welding process pioneered by General Motors is used in the thicker parts of the Corvette’s frame such as the tunnel sub-assembly and the principal attachments of numerous components. It is also used for welding aluminum extrusions, die castings, and aluminum sheet metal. All told, there are 439 spot welds.
 

The above process uses a patented electrode that disrupts the oxide on the aluminum’s surface for a stronger and more cost-effective weld. It is also licensed to several suppliers who produce subassemblies for the Corvette.
 
Lasers are used for continuous welds when single-sided access is available. The direct beam of heat helps with structural accuracy because there is less chance for a leak-free joint that would require more sealing and, hence, add weight. However, the most unique laser is the three-dimensional laser vision measurement system called Perception, which allow for variations to be addressed immediately, that may be the most interesting aspect of the laser systems being utilized.
 
Meeting the 25+% improvement in tolerance targets is immediately noticeable to the consumer. John Hennessey of Hennessey Performance is one of the first guys on the street to own a C7 Corvette – we featured his initial drag test a few days ago. He is “. . . very impressed with the C7′s overall build quality and fit and finish. The interior is tight and tidy. It’s the best built Corvette yet and truly America’s best sports car.”

Сето ова само покажува колку не се обрнувало внимание на вакви работи кај C6. Продажбата и редовите за чекање во целиот свет не само во САД, го потврдуваат значењето на овие детали.

[LosiPatista]

C6 беше напредок во однос на C5, колку што C7 е напредок во однос на C6.

Corvette оди 300кмх, забрзува до 100кмх за 4 секунди, има поголем џи форс од порше, гтр, ферари,ламборгини, вози исто или побрзо од нив. Има најдобро кочници во светот, и сето тоа го прави за 55к. Треба да ја изберат за кола на годината!

[Deni]

Јас искрено би ја гласал за кола на годината, без око да ми трепне. Си ја заслужува титулата.
