Toyota Motorsports have unveiled the first three teams that will run its Camry in Nextel Cup and Busch Series races in 2007: Bill Davis Racing, Michael Waltrip Racing and newly-formed Team Red Bull.

BDR brings long-time sponsor Caterpillar, while NAPA remains the primary sponsor for Waltrip. Bill Davis Racing was an early Toyota partner in the Craftsman Truck Series, while former Cup champion Darrell Waltrip is Toyota Motorsports most visible NASCAR spokesman.

Most interesting of the three is Team Red Bull. The entry of the youth-oriented beverage company and all-round adrenalin junkie into NASCAR Nextel Cup racing should shake things up quite a bit, if their impact on the Formula 1 paddock is anything to go by.

No official word on drivers, although Robby Gordon is rumored to be part of the Red Bull equation, and Michael Waltrip is certain to drive the NAPA Camry.
