As usual, this month's car pack injects your copy of Forza 4 with ten new cars to drive. The headlining ride is the 2011 Chevrolet #4 Corvette Racing ZR1. The game did ship with two Corvette Racing cars already, the 2004 #3 C5.R and 2006 #4 C6.R, both of which were much more dominant in their respective GTS and GT1 classes than this more recent ZR1-based car has been in the GT2 class, but its inclusion will round out your collection of modern ALMS Corvettes.
What you'll probably jump into first, though, is the 2012 Mercedes-Benz C63 AMG Black Series. We've driven it and you should too, even if it's only in the game. The 1987 RUF CTR Yellowbird is also nice to see in this pack, as well as the '92 Toyota Celica GT-Four RC ST185. You also get the original 1963 Volkswagen Beetle, 1997 Maserati Ghibli Cup, 1958 MG MGA Twin-Cam, 2011 Aston Martin Cygnet, 1940 Ford De Luxe Coupe and 1959 BMW 507.
Unfortunately, the Forza Motorsport 4 Season Pass has concluded, so everyone will have to pony up the 560 MS Points ($7.00) to play. A photo gallery and video showcasing the new cars are posted below.
