WRC:
Sebastien Loeb dominated Rally France in Corsica this weekend, putting his 23rd career victory in the record books. Despite running a two-year old Citroen Xsara against the newly-designed Ford Focus of Marcus Gronholm, Loeb led the rally from start to finish, relegating Gronholm to the runner-up step on the podium. Young Citroen phenom Dani Sorda narrowly beat out Ford's Mikko Hirvonen for the last podium spot. Full results at the Rally France website.

Champ Car World Series:
Sebastien Bourdais started 2006 where he left off last season - in victory lane. The two-time champion started from the pole and led 70 of 74 laps to win the Grand Prix of Long Beach for Newman/Haas Racing. Starting on the front row is always an advantage on a difficult-to-pass street circuit like Long Beach, and so it proved on Sunday when a massive tie-up in the first turn took out four of the top eight qualifiers. Bourdais and his front row companion Justin Wilson escaped the carnage, with RuSPORT's Wilson eventually capping a fine drive with a second-place finish. Alex Tagliani, driving for the Aussie Vineyards team, rounded out the top three. Rookie Katherine Legge managed an eigth-place finish, the best-ever by a woman driver in Champ Car. More info here.
 
Rolex Sports Car Series:
The Daytona Prototypes shared the Long Beach Grand Prix venue with Champ Car this weekend, in the first-ever street race for the class. Like the Champ Car race, the Rolex event was eventful, with the air full of flying carbon fiber throughout the event. The Lexus Riley of Scott Pruett and Luis Diaz came through unscathed, winning for the second time this year. Second place went to the Porsche-powered Crawford of Mike Rockenfeller and Patrick Long, while Shane Lewis and Bill Auberlen were the surprise third-place finishers in their BMW-powered Riley.
