2013 Chevrolet Corvette 427 Convertible 60th Anniversary
DETROIT – Chevrolet today unveiled the 2013 Corvette 427 Convertible Collector Edition – the fastest, most capable convertible in Corvette’s history – as well as a 60th Anniversary Package that will be available on all 2013 Corvette models.
“The 2013 model year will be historic for Corvette, marking its 60th Anniversary and the final year for the current ‘C6’ generation,” said Chris Perry, vice president, Global Marketing and Strategy for Chevrolet. “We couldn’t think of a more fitting way to celebrate these milestones than bringing back one of the most-coveted combinations in the brand’s history – the Corvette convertible and a 427 cubic-inch engine.”
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.
Corvette 427 Convertible Collector Edition
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 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 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.
The 427 Convertible is available in 2LT, 3LT and 4LT trim levels and will carry a unique 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 content includes 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.
Charity Auction at Barrett-Jackson Scottsdale
The first Corvette 427 Convertible offered to the public will go to the highest bidder at the Barrett-Jackson Scottsdale collector car auction, on Saturday, Jan. 21. Proceeds from the sale will benefit the Drive to End Hunger food relief program.
Chevrolet and Hendrick Motorsports are teaming up for the auction, including Hendrick team driver and four-time NASCAR Sprint Cup Champion Jeff Gordon. Team owner Rick Hendrick helped launch the Drive to End Hunger program with AARP and the AARP Foundation.
The Drive to End Hunger is part of a multi-year sponsorship for Gordon’s No. 24 Chevrolet. It calls on racing fans, corporations and charitable organizations to raise money, build awareness, and engage Americans who face the threat of hunger.
