Forza Motorsport 5's course list will include Laguna Seca and Spa-Francorchamps, developer Turn 10 Studios announced yesterday alongside the release of new screenshots for Gamescom 2013.
Mazda Raceway Laguna Seca, located in Monterey County, Calif., is famous for its "Corkscrew" sequence, a combination of a hard left and a hard right with a 59-foot drop in elevation within only 450 feet of track. (You can see the Corkscrew in the third screenshot above.) The course has also appeared in the four previous Forza Motorsport games.
The Belgian course Spa-Francorchamps is the home of the Formula One Belgian Grand Prix, and it is making its debut in the Forza series with Forza 5. Turn 10 did not release any screenshots of Spa-Francorchamps yesterday.
