Forza Motorsport 4's special edition ditches the game's red Ferrari cover star in favor of a bright blue BMW M5, a 96-page photo album presented by Top Gear, and a clutch of extra vehicles.

Forza 4 already has the Top Gear Track (Dunsfold Aerodrome) and an interactive car gallery with audio commentary from presenter Jeremy Clarkson.

The Limited Collector's Edition will bundle in a download code for five 2011 supercars in a VIP Pack and a further five as a "Launch Bonus" for those that order early.

Contained within the VIP Pack are the Bugatti Veyron Super Sport, Ferrari 458 Challenge, Lamborghini Gallardo LP570-4 Superleggera, Noble M600, and Ruf Automobile's Rt 12 R (a souped-up custom Porsche 997).

The Launch Bonus Pack comprises a classic Ford Mustang, the 1997 Lexus SC300's major revision, and 2011 editions of the Koenigsegg Agera, the Ruf RGT-8 (based on the Porsche 996), and the all-electric Tesla Roadster Sport.

There'll also be custom paintjobs for the BMW M6, M3 E92, Z4 M Coupe, M1 and M5, with the M6 livery decided by a community competition on the Forza website.

Forza Motorsport 4 is heading for an October 11 launch on Xbox 360.

That sets it between F1 2011 (360 PC PS3) on September 20 and Trackmania 2: Canyon (PC, also September), and Need for Speed: The Run which is currently scheduled for November 15.
