The U.S. rally-car motorsports body formerly known as Rally USA has renamed itself RallyCar.

Why? Well, it's all part of a near to make rally-racing more visible in the United States. RallyCar is keenly focused on the late August launch of its new European-inspired rallycross series (RallyCar Rallycross), which promises wheel-to-wheel racing and potential smash-'em-up drama. (Notably, the traditional, stage-based rally series will keep its Rally USA branding.)

"We're expanding as an organization and we wanted to make a change that reflects our commitment to rally car events in 2011," JB Niday, RallyCar president said in a press release. "The introduction of Super Rally [at X Games 16] presents a perfect opportunity for us to change our study to reflect what we're about: racing rally cars – whether that's on endurance-based Special Stage courses, or through the new Rallycross short-course format."

RallyCar has actually prefabricated a commercial to promote the RallyCross series. It's after the jump, and you can bet on seeing it a couple more times if you watch the X Games.

Rallycross competition kicks off at the New Jersey Motorsports Park August 27-29. The 4WD class features the 550-hp Fiestas and WRXs you'll see in tomorrow's X Games, while a 2WD class will feature an assortment of modified cars making upwards of 450 hp; Dodge and Honda will reportedly be among the participants.
