Ford Mustang GT
The 2011 Ford Mustang GT arrives with an all-new 5.0-liter V-8 engine, developed by a passionate team of engineers who rallied around the common goal of delivering more than 400 horsepower along with best-in-class fuel economy and driving fun.
Complementing those goals, a pair of new six-speed transmissions – one manual and one automatic – take advantage of the flexibility and fuel economy benefits of having six forward ratios, helping Mustang GT give powerful launches while also delivering relaxed cruising with exceptional fuel economy.
Chassis enhancements help improve the outstanding balance and driving behavior Mustang owners expect. Damper tuning and spring rates were revised to provide a smooth highway ride, while new rear lower control arms and firmer stabilizer bar bushings improve stiffness and handling for better cornering response over the highly praised 2010 model.
The six-speed automatic transmission in the 2011 Mustang GT will deliver fuel economy of 25 mpg highway and 18 city. This is up from 23 mpg highway and 17 city for the 2010 model. Six-speed manual transmission Mustang GT models for 2011 are projected to deliver 26 mpg highway and 17 city, matching the 2010 model but delivering significantly more horsepower and performance feel.
2011 Mustang GT fuel economy is enabled by Ti-VCT, the six-speed transmissions in automatic or manual variation, EPAS, additional tire spats and a rear decklid seal to enhance aerodynamics.
All-new aluminum four-valve-per-cylinder heads feature a compact roller-finger follower valvetrain layout leaving more room for high-flow ports for free-breathing performance. Head structure was designed to support higher cylinder head pressures and cross-flow cooling for sustained high-rpm use. Head bolt size was increased from 11 to 12 millimeters to contain the higher combustion pressures.
The aluminum block was developed for optimized windage and oil drainback under lateral conditions and high-rpm use, such as a track-day outing for an enthusiast owner or driver. Increased main bearing bulkhead widths and nodular iron cross-bolted main bearing caps with upsized bolts were also employed to accommodate the significant performance increase.
