Following up Jalopnik's own car pack, Forza Motorsport 4 is announcing their February DLC pack centered on sports racing cars. You can download it on Xbox LIVE starting on Tuesday, February 7 and we have the details on the ten cars getting released.

The stars of the pack are the sports racing cars from the past three decades. There's the 2011 Audi R18 that won the 24 Hours of Le Mans last year. On top of that Forza is getting the Mazda 787B, the only Japanese car to win outright at Le Mans. Forza designers must have had a hard time crafting the ear-splitting howl from its legendary quad-rotor Wankel engine.

The other classic sound that we're looking forward to is that of the Audi Sport Quattro rally car from the monster Group B era in the 1980s. These cars ran completely unrestrained inline-five engines and the roar they make is unforgettable.

The pack costs 560 MS Points, which equates to $7 in real American money. Those who have already purchased the Forza Motorsport 4 Season Pass can download this February pack for free.
