Covette Grand Sport Returns in 2010
I haven't been posting much about the Mustang's competition lately so I figured I'd start here. Looks like the Chevy Grand Sport returns for the 2010 model year. It runs the LS3 'vette engine which is rated at 430hp and 424 lb/ft torque. What differentiates it from the standard Corvette are a set of wide fenders which allow it to larger 275/35ZR18 tires in front and 325/30ZR19 tires in the rear. Other special effects include the Z06 style front splitter and tall rear spoiler, functional brake cooling ducts, and Z06 sized brakes. The full press release is below.
BOWLING GREEN, Ky. – Grand Sport. It's one of the most storied monikers in Corvette's illustrious racing heritage and it is returning the lineup. Chevrolet announced the new, 2010 Corvette Grand Sport at the 12th annual C5/C6 Corvette Birthday Bash, held at the National Corvette Museum, in Bowling Green, Ky.
The new Grand Sport model combines the Corvette's LS3-based powertrain with unique, wide body styling and a racetrack bred suspension for a distinctive, starting grid-ready performer. It is offered in both coupe and convertible body styles, with either a six-speed manual or six-speed automatic transmission. The LS3 6.2L engine is rated at 430 ponies and 424 lb/ft. of torque with the standard exhaust system. An optional two mode exhaust system elevates the power ratings to 436 horses (325 kW) and 428 lb.-ft. (580 Nm).
The Grand Sport replaces the Corvette's previous Z51 package and brings a greater degree of handling performance, with wider wheels and tires; revised shock, stabilizer bar and spring specifications and specific gearing. The equipment enables cornering capability of 1.0 g, as well as a 0.2-second improvement in 0-60 acceleration vs. standard LS3-powered models.
Grand Sport coupe models equipped with the manual transmission are uniquely outfitted for racetrack competition, too, with a dry-sump oiling system, differential cooler and a rear-mounted battery.
The complete list of content and special features for the Grand Sport includes
* Wider front and rear fenders – including specific front fenders with integrated Grand Sport badges
* Z06-style front splitter and tall rear spoiler
* Functional brake ducts and extra cooling

With its special equipment, the Grand Sport offers a different blend of performance and amenities. Its suspension package approaches that of the Z06, but includes a removable roof on coupes and, of course, the availability of a convertible body style. Also, the paddle-shift six-speed automatic transmission is offered, while a manual transmission is the only choice with the Z06.
All of Corvette's exterior colors are offered on the Grand Sport and an available Heritage package adds iconic front fender hash marks offered in four colors, as well as two-tone seats with Grand Sport embroidery. The Grand Sport can be ordered with 1LT, 2LT, 3LT and 4LT trim packages, too.
