The 2011 Chevrolet Camaro is still outselling the Ford Mustang, netting 19,972 sales through March compared to the Mustang's 15,419. Both cars handily outsold the Dodge Challenger, which itself is selling fairly well with 9,742 units through the same period. This is the second year running (well, so far this year at least) that the Camaro has managed stronger sales figures than the Mustang, having overtaken it last year for the first time since 1985.
GM figures the Camaro's success could be attributable to its relative newness in the pony car stable, having debuted in 2009. The Mustang has only undergone slight changes to its outward appearance since its 2004 redesign, though it's been kept well freshened in the engine bay. To help boost Camaro sales, Chevrolet says the V6 will get an 11-horsepower bump by this summer, taking the base Camaro to a total of 323 horsepower.
With such a big sales head start, it seems unlikely the Camaro will be caught before the end of the year, despite Ford's revised powertrain options for 2011 and the limited-production Mustang Boss 302 hitting dealerships soon.
