Forza Motorsport 4 is a 2011 racing video game developed by Turn 10 Studios and published by Microsoft Studios for the Xbox 360. It is the fourth installment in the Forza series. It is the first title in the series to support the Kinect sensor alongside the traditional controller-based gameplay. It is the last Forza Motorsport released for Xbox 360; 2012's Forza Horizon and its 2014 sequel were the last two Forza games for the platform, while 2013's Forza Motorsport 5 was released as an Xbox One exclusive.
A new feature in the series is Autovista, a game mode in which players can view precise details such as engine parts and interior gauges on a select number of cars. It features a partnership with BBC's Top Gear as well as its American counterpart. Jeremy Clarkson, then-presenter for Top Gear, provided commentary in the game's Autovista mode. Other partnerships include a two-year agreement with the American Le Mans Series (ALMS). Over 500 cars and 26 tracks are included.
The game received universal acclaim from critics, who praised the enhanced vehicle physics, updated visuals, and strong sound design. Several reviewers also gave high marks for the game's Autovista mode. Some critics expressed frustration with Kinect features, and others also felt that the game was not enough of an innovation from its predecessor, Forza Motorsport 3. These critics did, however, concede that the game was a vast improvement over Forza Motorsport 3.
