It was reported earlier this month that the Lamborghini Aventador Roadster could debut as early as next year. While that may sound like a rumor since we haven’t officially heard anything from Lamborghini itself, the United States fueleconomy.gov has confirmed the car’s existence.

The website recently updated its database for 2012 model years and under Lamborghini, we can see two vehicles listed – the Lamborghini Aventador Coupe and the Lamborghini Aventador Roadster.

According to the site, the Lamborghini Aventador Roadster will get an EPA fuel-economy rating of 11/17 mpg (city/highway) or 13 mpg combined – the same as its coupe sibling.
