2013 Corvette 427 Convertible Collector Edition Arrives Summer 2012

Many Corvette lovers have been holding back on a Corvette purchase, waiting to acquire one of the first very special Next Generation Corvettes, the C7.  We announced earlier this week that we are disappointed in the delay of the 2014 Corvette, not scheduled to arrive at dealerships until fall 2013.

So, today, Chevrolet reveals that they have exciting Corvette product for us in the 2013 Model Year!  Now, many of us will not wait until the 2014 Model Year to buy or lease.  The story falls in two parts. 

Part One is that all 2013 Corvettes will have an available option, the 60th Anniversary Appearance Package. Read CorvetteBlog on that subject tomorrow.

Part Two is the availability of the 2013 Corvette 427 Convertible Collector Edition (see photo)!  Boy is it pretty!  Frankly, we have heard for years that Chevy was reluctant to give us a Corvette Convertible with Z06 power.  However, aftermarket companies, like Callaway Cars, have insisted that the frame and composite body of the C6 Corvette were more than adequate to handle the massive power of the Z06 drivetrain.  Callaway has now been proven right by the factory!

The Corvette 427 Convertible blends elements of the Z06 and ZR1 models to create the fastest and most-capable convertible in Corvette’s history!  And, please note that the 427 Convertible Collector Edition is a model, and available in 2LT, 3LT, and 4LT trim.

Its heart is the 427-cubic-inch (7.0L) LS7 engine from the Corvette Z06. Rated at 505 horsepower (377 kW) and 470 lb.-ft. of torque (637 Nm), 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 engine 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 the engine that will power their new car.

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 fiber Z06-style 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

The weight reduction brings the 427 Convertible’s curb weight to 3,355 pounds (1,522 kg). 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. That’s better than:

  • 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 combination of low mass and high output will 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.
