First 2013 Chevrolet Corvette 427 Convertible

Fastest drop-top Vette ever.

The 2013 Chevrolet Corvette 427 Convertible is billed as the fastest drop-top Vette ever.

Detroit, MI (02.20.12) – The 7.0-liter, 505-horsepower monster is being billed as the fastest drop-top that Chevy has ever offered – and a good way to celebrate both the 60th anniversary of “America’s sports car,” and the likelihood this will be the last major variant off the soon-to-be-replaced C6 version of the Corvette.

Under the striped hood, that 7.0-liter V-8 – for the metrically challenged, that’s 427 cubic inches — mated to a 6-speed stick is the same basic drivetrain found in the Corvette Z06 Coupe.  But Chevy has incorporated some carbon fiber and other weight-saving measures to maximize the power-to-weight ratio.  That translates into a claimed 3.8 seconds 0 to 60, and a rated top speed of 190 mph.  To save you the effort of looking it up, the 427 is faster off the line than a Porsche 911 Turbo Cabriolet, the Audi R8 cabrio, a Ferrari California or an Aston Martin DBS.

Among other features, the 427 will share the rear- mounted battery and Magnetic Selective Ride Control system offered with the Corvette Z06, while ZR1-style wheels are standard gear.

The sixth-generation Corvette – C6 in Vette lingo – may be there to celebrate the 60th anniversary, but it won’t be around much longer.  Chevrolet is already in the final stages of development with the C7, a model that it hopes will take it even closer to its goal of being seen as a truly world-competitive sports car.

As has previously reported, GM engineers are taking an unusual approach to powering the C7, and barring any late changes they are expected to offer both a classic V-8, like the 427, while also introducing a more modern, downsized powertrain that will use forced induction into a small block to deliver an enormous specific output, likely well in excess of 150 hp per liter.
