Chevrolet unveiled the 2013 Corvette 427 Convertible Collector Edition as well as a 60th Anniversary Package that will be available on all 2013 Corvette models. The 60th Anniversary Package and 427 Convertible will make their public debut at the Barrett Jackson collector car auction in Scottsdale, Ariz., on Jan 21, and will arrive at U.S. Chevrolet dealers early this summer.

The Corvette 427 Convertible blends elements of the Z06 and ZR1 models to create the fastest and most-capable convertible in Corvette’s history. The American sports car is powered by 7.0 liter LS7 engine from the Corvette Z06. Rated at 505 horsepower and 637Nm 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.

The LS7 was co-developed with the Corvette Le Mans-winning GT1 engine and features lightweight titanium connecting rods and intake valves, as well as racing-inspired high-flow cylinder heads and a dry-sump oiling system. It is assembled by hand at GM’s Performance Build Center, where customers who purchase the 427 Convertible Collector Edition can purchase the Corvette Build Experience option and assemble themselves the engine that will power their new car.

Other options include 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. Lightweight machine-face Cup wheels – introduced on the 2012 Corvette Z06 with Z07 and Corvette ZR1 with PDE performance packages – come standard and include unique gray-painted pockets. Black Cup wheels or chrome ZR1-style wheels are also available.

The 427 Convertible also features several carbon-fiber components that help reduce weight, such as: carbon fiber raised hood (introduced on the 2011 Z06 Carbon Edition), carbon fiber Z06-style fenders and carbon fiber floor panels. The “CFZ” carbon fiber front splitter and rocker panels are optional on the 427 Convertible, and included with the 60th Anniversary package

The weight reduction brings the 427 Convertible’s curb weight to 1,522kg. 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 0-60 performance is 3.8 seconds, quarter-mile performance 11.8 seconds, the lateral acceleration of 1.04 g and the top speed is more than 190mph.

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

Corvette 60th Anniversary Package

All 2013 Corvette models, including the 427 Convertible, will be available with a 60th Anniversary Package, featuring an Arctic White exterior with a Blue Diamond leather-wrapped interior with suede accents. Convertible models will have a blue top.

Additional parts include a ZR1-style rear spoiler, special badging, gray-painted brake calipers and the “60th” logo on the wheel center caps, steering wheel and seat headrests. An optional graphics package adds full-length racing stripes in Pearl Silver Blue, including a tonal stripe stitched into the convertible top, extending the graphic theme over the roof.

For 2013, all Corvettes will feature 60th Anniversary badges on the fascias and the “waterfall” panel on convertible models, as well as 60th logos in the instrument panel gauge cluster and on the sill plates.
