When and where did GM publish 1/4 mile times?

The only 1/4 mile times I have seen on the new Z06 was by Hot Rod magazine????

The acceleration numbers were released well before the wreck at the Ring.

Corvette Z06 Sprints to 60 mph in Less than 3 Seconds

New eight-speed automatic enables 2.95-sec. 0-60 time, 10.95-sec. quarter-mile

2014-10-01

DETROIT – The performance of the all-new, 2015 Chevrolet Corvette Z06 establishes it as one of the most capable vehicles on the market – and one of the few to achieve sub-3-second 0-60 performance and a sub-11-second quarter-mile time.

“The Corvette has long been known as America’s sports car,” said Mark Reuss, General Motors’ executive vice president, Global Product Development. “With the capability of the new Z06 rivaling the best performance cars in the world, we will also be America’s Supercar.”

The Corvette Z06 accelerates from a rest to 60 mph in only 2.95 seconds when equipped with the all-new, available eight-speed paddle-shift automatic transmission – and achieves it in 3.2 seconds with the standard seven-speed manual transmission.

A quarter-mile sprint takes just 10.95 seconds with the eight-speed automatic and 11.2 seconds with the seven-speed manual. With both versions, the Corvette Z06 hits 127 mph at the end of the quarter-mile.

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.

“The defining aspect of driving the Z06 is seamless integration of power, technology and aerodynamics,” said Tadge Juechter, Corvette chief engineer. “As a result, the Z06 delivers ferocious acceleration, tenacious handling, and high-speed stability that few cars can match.”

It is the first Corvette Z06 with a supercharged engine – SAE certified at 650 horsepower and 650 lb-ft of torque – and the first with an available eight-speed paddle-shift automatic transmission. Performance-enhancing Magnetic Ride Control and Performance Traction Management are standard, and the award-winning, industry-first Performance Data Recorder is available.

The 2015 Corvette Z06 coupe goes on sale in in early 2015 priced at $78,995, while the Z06 convertible goes on sale in the second quarter, priced at $83,995.
