Forza 4 already has enough Porsche->ke1 vehicles to make the heads of even its most ardent fans spin in confusion. But even with all the Porsche bombardment, Turn 10 Studios still believes that you can't have too many of these virtual German prancers in your video game.

So they did something that, if not expected, can be construed as inevitable: release a Porsche Expansion Pack.

Forza 4's latest downloadable content will include 20 of the most iconic Porsche models to have met the pavement. The pack dropped on the Xbox LIVE network on May 22, 2012 costing 1,600 MS Points for the opportunity to access 30 new cars and 20 new career events, among other new other features.

Of the 30 that will be available in the pack, we've singled out a few of our favorite models: the 1955 Porsche 550 Spyder, the 1987 Porsche 959, the 2007 Porsche #80 Flying Lizard 911 GT3-RSR, and the 2012 Porsche 911 GT2 RS.

The pack is everything a Porsche fan could possibly ask for in a video game. If you don't want to take our word for it, take Turn 10 Studios', who said in a statement that “this is the kind of news that deserves to be shouted from the rooftops: Porsche is returning to Forza Motorsport.”
