2011 Mustnag V-6

“This car marks a new type of Mustang,” said David Pericak, Mustang chief nameplate engineer. “We’re using a high-performance quad-cam V-6 with all the bells and whistles in a car that’s become legendary for its handling and roadholding; it’s really going to get a lot of new sports coupe fans excited about Mustang, some for the first time ever.”

Powertrain improvements
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.

Drivers who prefer a manual gearbox will enjoy the short throws and direct feel of the shifter along with the relaxed cruising permitted by the extra top gear ratio. Customers choosing the automatic will be pleasantly surprised to find the advanced six-speed 6R60 transmission does not sacrifice fuel economy – or performance – for convenience, delivering an expected 30 mpg highway with crisp, quick shifts that maximize torque and horsepower.

The automatic transmission also features a grade-assist or “hill mode” to improve drivability on hilly terrain. This technical innovation uses vehicle input – acceleration, pedal position, vehicle speed and brake status – to automatically determine the correct gear ratio while on an incline or decline. Hill mode eliminates sixth gear, extends lower gear operation on uphill climbs, and provides additional grade or engine braking for coast downs.

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.

Fuel economy improvements
Extra horsepower and refined engine operation will be the most noticeable features to new 2011 Mustang 3.7-liter V-6 buyers while projected class-leading fuel economy, also a standard feature, offers an additional bonus. The numbers speak for themselves:

19 mpg city/30 highway with six-speed automatic transmission, up from 16 mpg city/24 highway on the 2010 model with automatic – a 25 percent improvement over 2010
18 mpg city/29 highway with six-speed manual transmission, up from 18 mpg city/26 highway on the 2010 model with manual
Refinements throughout Mustang’s body, powertrain and chassis design contribute to the improved fuel economy numbers. Examples include:

- The new Electric Power Assist Steering (EPAS) system which eliminates the drag of an engine-operated hydraulic power steering pump
- Six-speed transmissions that allow lower cruising revs without sacrificing off-the-line performance

- Aerodynamic improvements such as a new front fascia

- Tire spats on the rear wheels

- Modified underbody shields

- A taller air dam and an added rear decklid seal
Handling and driving dynamics
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.

The addition of EPAS marks a new era in driving dynamics for Mustang owners. Steering effort at parking lot speeds is reduced, while high-speed and highway feel is improved for more precise steering and handling. Because the belt-driven power steering pump is eliminated, EPAS provides a quieter vehicle with fewer components drawing engine power.

EPAS also enables new technologies that adjust for minor driving annoyances. Pull-Drift Compensation adjusts the steering to correct for crosswinds and minor road crowning, while Active Nibble Control helps eliminate the “shimmy” felt at high speeds when a wheel is out of balance or a brake rotor is warped. Both conditions are alleviated by EPAS independent of driver input, helping ensure Mustang delivers a smooth, comfortable driving experience in all conditions.

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 by directing engine torque to the rear wheel with the most traction. When the time comes to slow things down, the 2011 Mustang is also equipped with larger four-wheel ABS disc brakes, with 11.5 inch front and 11.8 inch rear rotors.
