Corvette 427 Convertible Collector Edition
January 13, 2012
The Corvette 427 Convertible blends elements of the Z06 and ZR1 to create the fastest and most-capable convertible in Corvette's history.
Its heart is the 427-cubic-inch (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.
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 Collect Edition can purchase the Corvette Build Experience option and assemble the engine that will power their new ca.
Supporting performance elements in the Corvette 427 Convertible 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, including:
- Carbon fiber raised hood (introduced on the 2011 Z06 Carbon Edition)
- Carbon fiver Z06-sytle fenders
- 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
- Porsche 911 Turbo S Cabriolet - 6.90
- Audi R8 5.2 RSI Spyder - 7.58
- Aston Martin DBS Volante Convertible - 7.82
- Ferrari California Convertible - 8.31
The 427 Convertible is available in 2LT, 3LT and 4L trim levels and will carry a unique vehicle identification number sequence, similar to the Corvette ZR1.
