Interesting. The last 2013 Corvette test information from Motortrend for comparison.
"At 3404 pounds, the 427 weighs just 151 pounds more than the Z06/Z07 we tested last year on the same tires. When you're dealing with 505 horsepower and 470 lb-ft of torque delivered on a "curve" as flat as a pool table, 151 pounds is nothing. Just look at the numbers: The 427 hit 60 mph in 3.8 seconds, same as the Z06/Z07. In 60-0-mph braking, the 427 actually beat the Z06/Z07 by 1 foot, stopping in just 101 feet. The quarter mile, though, is where we really saw the difference. The 427 was just a tenth behind in the quarter, running it in 11.9 seconds to the Z06/Z07's 11.8, but the 427 tripped the light traveling 121.5 mph while the Z06/Z07 was doing 123.4 mph. The difference was also evident on the skidpad, where the 427 posted a max of 1.06 g average to the Z06/Z07's 1.08 g average. As you can guess, that translated to the figure eight as well, where the 427 ran a 24.1-second lap at 0.84 g average to the Z06/Z07's 23.1-second lap at 0.90 g average. The 427, then, really is a credible Z06 convertible."
