Chevrolet unveils limited edition Indy Impala.

Chevrolet is introducing a special 2004 Impala Indy SS to commemorate its long relationship with the Indianapolis Motor Speedway and the Indianapolis 500.

The limited-edition model will have a production run of 4,088 units and is being offered through select Chevrolet dealerships in the United States and Canada. It is believed that this is the first passenger car other than an official pace car to feature an Indianapolis Motor Speedway and Indianapolis 500 theme.

The Indy SS package is based on the new-for-2004 Impala SS sedan. At its heart is GM's 3800 Series II supercharged V-6, delivering 240 horsepower at 5,200rpm and an impressive 280lb/ft of torque at 3,600rpm. The torque curve is consistently high over a broad operating range, providing instant off-the-line acceleration and ample power for highway merging and passing.

Unique to the Impala Indy SS are 17-inch chrome diamond-cut aluminum wheels, monotone cross-lace grille with 'gold' Chevy bowtie emblem and a rear spoiler. There's no doubt as to the connection with the 2.5-mile oval, as the Indianapolis Motor Speedway's famous 'Wing and Wheel' logo is found on the front fenders and instrument panel, as well as embroidered into the front seat head restraints and floor mats.

Like the standard Impala SS, the Indy SS is available only in a monochromatic black exterior, complimented with gray leather seating surfaces inside.

Expanding Chevrolet's relationship with the Indianapolis Motor Speedway this year is the announcement that a 2004 Corvette will serve as the official pace car of this year's Indianapolis 500 on 30 May. This marks the third consecutive year and 15th time overall that a Chevrolet product has served as the official pace vehicle - the most appearances by any brand in the history of race.
