Behind its dramatically restyled front fascia, the 2014 Corvette Stingray packs a new 450-hp 6.2-liter V8 engine. Not surprisingly, that engine isn't quite powerful enough for some gear-heads. Well before the new 'Vette makes its way into showrooms later this year, Hennessey Performance is teasing potential buyers with a version that puts out more than double the horsepower.

Never one to approach a tune with a light hand, Hennessey plans to offer several packages for the 2014 Corvette, including supercharged and twin-turbo variants. The supercharger will boost output up to 700 hp, while the twin turbochargers will send it soaring to up to 1,000 hp. An 800 hp twin-turbo version is also planned.

In addition to forcing air into the new LT1 V8, Hennessey will offer buyers a variety of upgrades, including cat-back exhaust, stainless steel long-tube headers, tuned suspension, Brembo brakes, and wheel and tire upgrades.

Hennessey's packages will be available on both the C7 coupe and convertible models. Edmunds reports that the 1,000-hp package will set buyers back an extra US$69,500 over the yet-to-be-announced sticker price of the Corvette.

While a 1,000-horse corral is sure to offer impressive performance, the stock Corvette is no slouch. Thanks to its new engine and lighter materials, the new Corvette will bolt to 60 mph in under four seconds. With a stretched wheelbase and widened track, it should be more surefooted and agile, too. And one place it will certainly beat the Hennessey version: fuel economy. Chevy says that the new Stingray will be the most fuel efficient Corvette ever, estimating highway mpg at 26.
