Shift 2: Unleashed was developed by Slightly Mad Studios, released on March 29, 2011 and is the sequel to 2009's Need for Speed: Shift. Shift 2 expands on the gameplay and features introduced with the original.

Shift 2 includes the Autolog feature introduced with Hot Pursuit, which allows players to keep track of their friends progress of achievements as well as best lap times.[156] It also includes features such as night racing, an in-helmet camera, a more in depth career mode with different areas to complete. The driver aggression/precision aspect of scoring has been taken away to free up the game, and to focus more on the driving experience rather than getting points divided into two sections. There were many minor improvements (including a full damage model now, and improved car flip physics) that were added to Shift 2 and polished the game in its entirety.

Shift 2 features more than 140 licensed vehicles available for racing and tuning, a smaller number compared with racing sims such as Forza Motorsport 3 and Gran Turismo 5. However, executive producer Marcus Nilsson said the studio wanted to concentrate on having only the must-have speedsters. There are also 40 real-world locations including Bathurst, Spa-Francorchamps and Suzuka as well as fictional circuits like downtown London and Shanghai.
