GM Looks for Most Powerful Camaro to Overtake Mustang Again

There’s nothing like a good old Detroit bragging contest. General Motors Co.’s bread-and-butter Chevrolet brand took the wraps off its new Camaro, revealing a performance version that tops the Ford Mustang’s by 20 horsepower.

GM is boasting that the high-performance SS version of the sixth-generation Camaro, revealed Saturday at Belle Isle on the Detroit River, is the most powerful pony car it has ever built, with a 455-horsepower V-8, compared with 435 for the Mustang GT. And with regular unleaded gasoline averaging less than $2.70 a gallon -- almost a dollar less than a year earlier -- muscle cars seem back in vogue.
