Porsche makes its Forza 4 debut in May

Porsche was absent from the racing lineup in Forza 4, much to the disappointment of many series fans -- including Turn 10 creative director Dan Greenwalt. It was with visible pleasure, then, that Greenwalt announced the return of the iconic German roadsters at an Xbox showcase event last week.

Set to arrive in May, the Porsche Expansion Pack -- priced higher than the usual DLC, Greenwalt said -- adds 30 new cars to the game, seven of which are entirely new to the series Greenwalt wouldn't go into specifics on the lineup, but confirmed the Porsche Expansion Pack adds 20 new Porsche events, fully integrated into the main campaign, and brings the total number of cars available in Forza 4 to 625.
