Chevrolet marks the 2013 model year with the Corvette 427 Convertible Collector Edition as well as a 60th Anniversary Package available for all 2013 Corvettes.

The Corvette 427 Convertible blends elements of the Z06 and ZR1 models to create the fastest and most-capable convertible in Corvette's history.

Its heart is the 7.0L LS7 engine from the Corvette Z06. Rated at 505 horsepower and 470 lb.-ft. of torque, it is the most powerful engine ever installed in a production Corvette convertible -- and, like the Z06, the 427 Convertible is only available with a six-speed manual transmission.

Supporting performance elements in the Corvette 427 Convertible are the driveline and rear axle system from the Corvette Z06, a rear-mounted battery and standard Magnetic Selective Ride Control. The standard 19-inch front and 20-inch rear wheels are wrapped in ZR1-style Michelin PS2 tires.

Weight reduction brings the 427 Convertible's curb weight to 3,355 pounds. Combined with its 505-horsepower LS7 engine, it gives the 427 Convertible a power-to-weight ratio of 6.64 -- or one horsepower for every 6.64 pounds of vehicle mass.

The combination of low mass and high output make the 427 Convertible one of the fastest convertibles in the world, delivering estimated 0-60 performance of 3.8 seconds, quarter-mile performance of 11.8 seconds, lateral acceleration of 1.04 g and a top speed of more than 190 mph.

The 427 Convertible is available in 2LT, 3LT and 4LT trim levels and carry a unique vehicle identification number sequence, similar to the Corvette ZR1.

All 2013 Corvette models will be available with a 60th Anniversary Package, featuring an Arctic White exterior with a Blue Diamond leather-wrapped interior with suede accents.
