Last year, Sebastien Loeb swapped his WRC Championship winning Citroen
Xsara for a test in Renault's
F1 car (and former Renault driver Heikki Kovalainen hopped in the Citroen). This year, Loeb's going to take a turn in Red Bull's
F1 runner for a test at the Catalunya circuit on November 17th -- Red Bull also sponsors Loeb's WRC team. The difference this time: instead of a quiet get-to-know-the-car session, Loeb will be running with the other teams and drivers during an official F1 testing session. Although he'll be piloting the Renault-powered RB4 with a mission not to embarrass himself, he has no plans to vacate his Citroen rally seat. After five straight WRC championships, piloting an F1 car is just what you do in your time off, for fun. Must be nice...
