Ford EcoBoost engine - Wikipedia, the free encyclopedia

EcoBoost is a family of turbocharged, direct injected six-cylinder and four-cylinder gasoline engines produced by the Ford Motor Company.

Yep, no turbo on the all new 2011/2012 V6 Mustang engine.

Unlike the old 4.0, which for 2010 still employs a heavy iron block, an archaic two-valve/cylinder single-overhead-cam valvetrain, and a measly 210 horsepower, the new 3.7-liter is a technological tour de force. From lightweight aluminum architecture and a four-valve/cylinder dual-overhead-cam valvetrain to twin independent variable cam timing (Ti-VCT) and a deep-sump aluminum oil pan that stretches oil-change intervals to 10,000 miles, the 3.7 boasts modern goods. More important, it boasts the goods that matter to enthusiasts: horsepower, as in 305 of them. And torque? Try a very healthy 280 pound-feet, or 40 more than that of the 4.0.
