Forza 3 fans can add to their car collections in a big way this holiday season, thanks to two downloadable car packs.

The first is the Hyundai Genesis Coupe pack, which is now available for free for Xbox Live Gold subscribers. Contained therein are a Rhys Millen Racing Red Bull Hyundai Genesis Coupe, a HKS Genesis Coupe, and a Forza 3 themed Genesis Coupe.

The second car pack, the Hot Holidays Car Pack, will be released on December 8 at a cost of 400 MS Points ($5). Developer Turn 10 has yet to announce which cars you’ll get in the pack, save for one: a Ferrari 458 Italia. Further details are set to be released between now and the pack’s launch via the game’s website.

Also on December 8, a single car – a 2010 Audi S4 – will be made available as a free download.
