One day after Tesla unveiled the Model X, without any advertising, advance sales of the Model X exceeded $40 million the California based automaker said Wednesday.

The Model X, Tesla’s first crossover that comes out next year, is derived from the underpinnings of Model S car. The mid- size SUV, touted by Tesla as faster than Porsche AG’s 911 sports car and roomier than the Audi Q7 SUV, will be built in 2013 at the Fremont plant that starts making the Model S this year.

With Delorean-style gullwing doors, distinctive sheet metalwork and a range of neatly executed design flourishes, the car still resembles a vehicle of the future.

Production is scheduled to begin at the end of 2013, said Tesla. It expect to produce 10,000 to 15,000 Model X vehicles a year.

Tesla said it has delivered more than 2,000 roadsters to customers worldwide. It will begin deliveries of the Model S, the first premium sedan to be built from the ground up as an electric vehicle, in mid-2012.
