Art Gruszka won the 4WD Class final in a controversial finish at the U.S. Rallycross Series event Saturday at New Jersey Motorsports Park in Millville.

Gruszka was bumped on the last lap by David Sterckx, who was attempting a pass for the lead. Sterckx was disqualified for the move, and Gruszka, despite spinning out, recovered to finish the race on a flat tire.

"I looked in the mirror and didn't see Sterckx," Gruszka said in quotes provided by the series. "This race was very fast. The car was very fast."

Dillon Van Way won the 2WD Super Class.

Colli•Wooding, of South-ampton Township, Burling-ton County, won the 2WD Limited Class.

It was the second of three U.S. Rallycross Series events at NJMP this year. The third will be Oct. 20.
