Yes, that's the N54. Here's what the "Innovations" page on bmwusa.com has to say about the N54:


3.0-liter, turbocharged 6-cylinder engine, 300 hp
Generating 300 hp and 300 lb.-ft. of torque at 1400-1500 rpms, this advanced inline six is our first turbocharged engine offered in the U.S. in decades. Turbo lag has been virtually eliminated, thanks to Double-VANOS "steplessly" variable valve timing, direct fuel injection, and BMW's inspired use of the latest TwinPower Turbo technology. By using direct fuel injection - a high precision fuel injection system - we have overcome the traditionally poor gas mileage of turbocharging. The engine's innovative design includes an all-aluminum engine block with cast iron sleeves for durability, and a direct fuel injection system that also cools the engine. A cooler engine allows for a higher compression ratio (10.2:1 vs. 6:1 and 7:1 in other turbos), which translates into superior emission control, greater fuel efficiency and, most importantly, a thrilling performance.
