2013 Chevrolet Corvette Grand Sport
8-cyl. 376cid/430hp SFI
With an experienced team and a lot of data.
2013 marked the final year of the production run for the sixth-generation (C6) Chevrolet Corvette. Not content to let the Corvette soldier on unchanged, GM introduced a Corvette 427 Convertible Collector Edition – a ragtop ‘Vette with the Z06’s massive 7.0-liter (427 cid) engine stuffed under the hood.
This year also marked the 60th anniversary of the Corvette, and commemorated it with an available 60th Anniversary package for a number of trim levels of the Corvette, including 4LT, 3LZ, and 3ZR. This special package included a white paint job with silver racing stripes, ZR1 rear spoiler, gray painted brake calipers and, of course, special badging.
For the final year of the C6, the Corvette could still be had in Coupe, Convertible, Z06, Grand Sport, and ZR1 variants. The Coupe, Convertible, and Grand Sport have GM’s 6.2-liter V8 making 430 horsepower through either a 6-speed manual or 6-speed automatic transmission. The Grand Sport features the same engine but with a host of performance enhancements, including a dry-sump oil system, larger brakes, wider bodywork, wider tires, and sway bars.
As with previous years, the Z06 was powered by a 7.0-liter (427 cid) V8 with 505 horsepower sent through a manual transmission. The Z06 has a wider body and fixed coupe roof. The top performer was still the ZR1, with its supercharged 6.2-liter V8 engine making 638 horsepower.
For the final year of production, just 482 examples of the ZR1 were built, compared to 2552 examples of the 427 Convertible. The most popular version of the 2013 Corvette was the Grand Sport Coupe, with over 4900 examples built.
