Earlier this year, Chevrolet announced the return of the Corvette Grand Sport model. It's a track-oriented Corvette with wider wheels and tires, special suspension tuning and unique exterior details. The Corvette Grand Sport achieves a 0-60 time of less than four seconds, pulls 1.0 g on the skid pad and still boasts an EPA-rated highway fuel economy 26 mpg.

The version displayed at SEMA introduces a host of Grand Sport accessories that will be offered in 2010. It is a standard Grand Sport convertible equipped with the Heritage Package, but in a new Cyber Grey exterior color, with forthcoming accessories that include:

* Mesh inserts for the front fender vents

* ZR1-style front splitter and rear spoiler (painted satin black)

* ZR1-style rocker extensions and wheel spats (painted satin black)

* Body-color door handles and license plate frame

* Tinted dark chrome fender badges

* “Tech” pattern engine cover with red lettering inserts

* Grand Sport-logo hood blanket

* Grand Sport-logo floor mats and leather console cover

* Red stitched shifter knob/boot and red parking brake boot

* “Tech” pattern interior trim kit

* PAL iPod connector

* Convertible wind screen

* Racing-style pedal covers

* Interior storage pouches

The Grand Sport accessories are expected to go on sale in early 2010. They're available through any Chevrolet or other authorized GM dealer.
