Chevrolet has announced an update to its iconic Camaro pony car set to be unveiled next month.

The Camaro ZL will be the most powerful Chevrolet convertible ever, with a supercharged 6.2-liter engine rated at 580 horsepower (432 kW).

The output will outshine models including the Aston Martin DB9 Volante, the Mercedes SL63 AMG, the Porsche 911 Turbo S and the Ford Shelby GT500.

Chevrolet has released details of the 45th anniversary edition of its Camaro sports car, set to be unveiled at a Camaro fan event April 15.

The enhancements for the Camaro, the most popular sports car in the US, cover both performance and design and coincide with the birthday celebrations for the vehicle, first launched in 1966.

The 2012 Camaro will feature an improved version of the current model’s 3.6 liter V-6 engine, which adds an increase of 11 hp (8kW) to bring the total to 323 hp (241 kW).
