Forza Horizon will get a free 'Honda Challenge Car Pack' from Xbox LIVE on January 15, 2013.
Turn 10 has revealed details of the pack, saying it'll add in three new cars (the 2013 Honda Civic Si Coupe, HPD Rally Fit, and the 1986 Honda Civic Si Coupe) and a brand new Rivals event (the '2013 Civic Si Challenge').
