Sexy car racer Danica Patrick has a new notch on her seat belt: toy-car driver.

Patrick unveiled her new "Danicar" this weekend at the Daytona International Speedway. The custom die-cast vehicle was co-designed with the Hot Wheels team at the Mattel Design Center in El Segundo, California. Patrick's "Danicar" is the first celebrity-designed Hot Wheels vehicle and will be made in the traditional 1:64 scale.

"My life is all about high velocity cars, and the only car company I could imagine being able to create my vision of the ultimate fantasy car is Hot Wheels," Patrick said.

Mattel calls the "Danicar" an "awesome machine." It features an open cockpit, chartreuse "Spectraflame" paint, three sets of different-sized wheels and adjustable wings on the front and back.

The car will be available in stores this fall.
