NASCAR may be saying goodbye to the Monte Carlo. Although it has been the most successful car in Nextel Cup racing history, GM has apparently gotten approval from NASCAR to replace it. According to a report in the Charlotte Observer, NASCAR has given General Motors permission to drop the Monte Carlo SS, and replace it with the Impala SS. This despite the fact that the Monte Carlo has the most Cup wins of any model in history with 400. Sources told the Observer a Hendrick Motorsports built Impala SS by will be unveiled at the official announcement Friday at Atlanta Motor Speedway.

The Impala actually won the Cup way back in 1960 and 1961, but the Monte Carlo took over the NASCAR duties for Chevy after its debut in 1969. The Monte didn't actually race until 1971, but it captured the pole for its first race at the 1971 World 600 at what is now Lowe's Motor Speedway. The new Impala SS will run in 16 Nextel Cup races next year, according to the Observer. It will be used as Chevrolet's version of NASCAR's "car of tomorrow." In races where they aren't using the "car of tomorrow," Chevy teams will still use the Monte Carlo.
