The next bit of Forza Motorsport 4 car DLC is on the way, and the folks at Turn 10 and Microsoft Studios are teaming up with us here at IGN to bring you a new crop of awesome rides. The December IGN Pack includes 10 brand new cars, including turbo-charged new rides like the 2011 Monster Sport Suzuki SX4 and the classic 1957 Maserati 300 S.
The December IGN Pack is launching for 560 MS Points ($7 USD) on December 6, 2011. If you’ve purchased a Forza Motorsport 4 Season Pass, however, the pack will be available at no additional cost. A Season Pass can be picked up through the Xbox LIVE Marketplace or participating retailers, including Best Buy and GameStop, for 2400 Microsoft Points ($29.99 USD), and gives you access to all six planned game add-on packs for Forza Motorsport 4 at 30 percent savings.

1977 Ford Escort RS1800
With a storied history in rallying and a body style that’s ripe for race replica paints (or whatever style you like, really), the 1977 Ford Escort RS1800 should prove as desirable in Forza 4 as it is by Ford enthusiasts and collectors in real life. Begun in 1975, the RS1800 used the legendary Cosworth 1.8L BDA engine, which churns out 115 horsepower, and powered its way to multiple rally wins and a couple of World Championships.
