Four-Hundred and How Many Horses? Chevrolet Finally Announces 2014 Corvette Stingray’s Power Figures

When Chevrolet pulled the sheets off of the 2014 Corvette Stingray at this year's Detroit auto show, we were smitten with its saucy sheetmetal, upgraded interior, and promising-looking all-new small-block V-8 engine. We were less enthused with the mystery surrounding the small-block's details, which Chevy would specify only as making roughly 450 horsepower—until now. The automaker finally has revealed the Corvette's output secrets, and the base car's 6.2-liter V-8 makes a burly 455 horsepower and 460 lb-ft of torque. Now that everyone can sleep easier knowing just how beastly the standard '14 Corvette coupe and convertible will be, get ready to rest even easier: With an optional performance exhaust, the 6.2-liter's output figures jump to 460 horsepower and 465 lb-ft of torque. Sans the freer-breathing pipes, the Corvette still packs 25 more ponies and 36 more lb-ft of twist than the outgoing Vette's 6.2-liter LS3 V-8. (That car also offered a performance exhaust, which added 6 horses and 4 lb-ft.) The new LT1′s power peak hits just 100 rpm later, while its maximum torque is available at the same 4600 rpm as the old LS3. In fact, the new LT1 V-8 approaches the kind of power territory occupied by current Z06. For reference, that model's 7.0-liter LS7 V-8 pumps out 505 horsepower and 470 lb-ft of torque.

We've sampled GM's latest cylinder-deactivation system as applied to the 5.3-liter V-8 (also a member of the General's newest-generation small-block family) in the 2014 Silverado pickup and can report that it operates seamlessly and without any bad vibes. As for the performance parameters that matter to those interested in the Corvette's sports-car chops, Chevrolet estimates that the base Stingray should hit 60 mph in less than four seconds. Have we mentioned that we want to drive this thing? Badly. from Car and Driver Blog http://blog.caranddriver.com
