U.S. government confirms Lamborghini Aventador Roadster for 2012

The U.S. Department of Energy isn't a typical source for car news, but the agency has just confirmed the Lamborghini Aventador Roadster.

Lamborghini has yet to announce a convertible variant of its all-new Aventador LP700-4, but the United States government has just confirmed an Aventador Roadster is in the works and will launch sooner than expected.

Lamborghini executives haven't exactly denied the existence of an Aventador Roadster, but the Italian automaker has also yet to officially confirm such a model. However, we don't have to wait for that official announcement any longer as the U.S. Department of Energy's fueleconomy.gov Web site has confirmed that a convertible version of Lamborghini's flagships is just months away from a U.S. launch.

The fueleconomy.gov Web site has been updated with some automakers' 2012 model year cars, with Lamborghini among them. One click on the Lamborghini name reveals two models for 2012 - the Aventador Coupe and the Aventador Roadster.

In addition to just confirming the car, the Web site has also provided us with an updated timeframe for launch. It was originally thought that the Aventador Roadster wouldn't launch until sometime in 2014, but the car's 2012 designation suggests it will launch well before then. If the site's information proves accurate, expect to see the Aventado Roadster on the market no later than early 2012.
