Because EA is evil, that's why. Kidding! See, EA has the license for Porsche cars, thus, making them available only via a sub-licensing deal. The cars did appear in Forza 3, and featured RUFs, which are tuned, unmarked Porsches.
But this time around, no dice. "In the end, however, EA couldn't see their way towards collaborating again," blogged Brian Ekberg from developer Turn 10.
"We've asked our contacts at EA to reconsider their position frequently and regularly over the last 18 months," he continued. "We also reached out to various influential people in gaming to lobby on our behalf, and on your behalf, but that was to no avail."
