For the uninformed, the Fast and Furious DLC is part of a partnership to promote the release of Furious 7, which is hitting theaters on April 3, 2015. As part of the promotion, the expansion pack will be available for free to download from March 27 to April 10. After that period ends, you to pay $10.
In Forza Horizon 2’s Fast and Furious DLC, you are tasked with sourcing cars to Tej Parker. You will be able to unlock new cars used in the movie for the free roam mode, including the 1970 Dodge Charger R/T, 1970 Plymouth Cuda, 1970 Plymouth Road Runner, 1998 Toyota Supra, 2012 Nissan GT-R, 2013 Jeep Wrangler, 2014 Maserati Ghibli S and 2015 Dodge Charger.
The download size is pretty big for an expansion. Thankfully, you can add more space to the Xbox One by using a compatible external HDD. Forza Horizon 2 was released by Microsoft Studios on the 30th of September for the Xbox One as well as the Xbox 360 last-gen console.
