New V-6 engine
For 2011, Mustang's new 3.7-liter Duratec 24-valve V-6 uses advanced engineering to deliver its power and economy: Twin Independent Variable Camshaft Timing (Ti-VCT) adjusts the valvetrain in microseconds. Aluminum construction means light weight. It's an engine designed to crank out torque down low, rev to 7,000 rpm and deliver the mechanical music sports coupe lovers crave everywhere in between with a projected 30 mpg on the highway with a six-speed automatic transmission and fun for drivers on nearly every road.
"Mustang is completely transformed with this new engine," said Derrick Kuzak, group vice president, Global Product Development. "Everything people love about the car is still there and now under the hood is a V-6 engine that uses premium technology to deliver the power, the feel, the fuel efficiency, even the sound of the best sports coupes in the world."
With Ti-VCT operating its four valves per cylinder, the new Mustang V-6 powerplant sends significantly more horsepower and torque (305 hp and 280 ft.-lb.) to the rear wheels than its predecessor despite its smaller displacement. The behind-the-wheel feel is unlike any Mustang ever produced.
The high output is due largely to Ti-VCT which allows variable control of valve operation across the rev range. The variable cams operate on a Direct Acting Mechanical Bucket (DAMB) valvetrain. The end result is as much as a 3 percent improvement in fuel economy and a 10 percent improvement in power output versus traditional engines.
Performance was the mantra for every aspect of engine design. A cold air induction system and dual exhaust give the 3.7 its free-breathing style with a 7,000 rpm redline and near-instantaneous response to throttle inputs.
Drivers can get the most out of the new V-6 engine's output using either an all-new six-speed manual gearbox or a six-speed automatic transmission. Both come with the flexibility and fuel economy benefits of six forward ratios regardless of whether buyers want to shift for themselves or not.
The standard 2.73 rear axle provides an ideal blend of cruising fuel economy and acceleration, aided by the wide ratio spread permitted through the use of six forward speeds in the gearboxes. Performance enthusiasts can select an available 3.31 rear axle ratio for better off-the-line launch characteristics.
With so much additional horsepower standard, the 2011 Mustang received enhancements to its chassis to maintain the outstanding balance and driving behavior Mustang owners expect. Damper tuning and spring rates were revised to provide a smooth highway ride while a new rear lower control arm and stiffened stabilizer bar bushings improve stiffness and handling for better cornering response.
While Mustang's aerodynamic improvements were designed mainly to improve fuel economy, engineers also adjusted the vehicle's front/rear lift balance. The result is a car that tracks more securely and feels more "planted" to the road surface at higher speeds, helping to keep the tires in better contact with the pavement.
Mustang buyers choosing the new V-6 will also get a standard limited-slip differential that provides better handling and more sure-footed grip in poor weather conditions. When the time comes to slow things down, the 2011 Mustang is also equipped with larger four-wheel ABS disc brakes.
Additional lightweight soundproofing measures help filter unpleasant, high-frequency noises while tuned intake and dual exhaust add the sounds Mustang buyers relish.
Enthusiasts who want a premium performance-oriented Mustang V-6 can opt for the new Performance Package, which will be available August 2010. Designed for driving enthusiasts, the Mustang V-6 Performance Package comprises: A 3.31 rear axle ratio for quicker off-the-line acceleration, Firmer Mustang GT suspension, 19-inch wheels, Summer performance tires for improved grip, A strut tower brace for increased chassis rigidity, Unique electronic stability control calibration with sport mode for performance driving.
