Ford has announced that the 2011 Mustang GT will arrive with an all-new 5.0-liter V-8 engine, developed by engineers who rallied around the common goal of delivering more than 400 horsepower.
The modern 5.0-liter four-valve Twin Independent Variable Camshaft Timing (Ti-VCT) V-8 engine in the new Mustang GT will deliver 412 horsepower and 390 ft. lb. of torque.
At the same time, fuel economy is projected to be better than the previous model and unsurpassed in the segment.
“This all-new 5.0-liter engine is the next chapter in the development of the world-class Mustang powertrain portfolio,” said Derrick Kuzak, group vice president, Global Product Development. “It’s a thoroughly modern engine for the times, delivering the performance and fun-to-drive factor that enthusiasts want while improving fuel economy.”
A critical element in the 5.0-liter V-8’s ability to deliver 412 horsepower, with improved drivability, tractability and fuel economy over the 2010 Mustang GT powertrain, is enhanced Ti-VCT. For a high-performance application, the team specified cam-torque-actuated variable camshaft timing. Using existing cam torque energy, with assistance from pressurized oil, meant that minimal upgrades to the oil pump were required, resulting in less parasitic drag. Increased volumetric and thermal efficiency gives faster Ti-VCT response at all engine speeds.
The all-new aluminum four-valve-per-cylinder heads feature a compact roller finger follower valve train 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.
The aluminum block was developed for optimized windage and oil drainback under lateral conditions and high rpm, such as a track-day outing for an enthusiastic owner and 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.
Specially designed tubular exhaust headers were developed to maximize exhaust pulse separation and improve flow. A team analyst actually fabricated the tubular headers in his home workshop, bringing the CAE design to life.
The six-speed automatic transmission on the 2011 Mustang GT will deliver up to an estimated 25 mpg highway and 17 in the city, 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 24 mpg highway and 16 city, matching the 2010 model but delivering significantly more horsepower and performance feel.
The 2011 Mustang GT also features an enhanced rear lower control arm to add stiffness, improve powertrain NVH control, and sharpen handling. A stiffened rear stabilizer bar for better on-center steering is also included. Stabilizer bar diameters, spring rates, and dampers all have been tuned for improved dynamics.
A Brembo brake package upgrade will be available for serious enthusiasts. This package includes 14-inch vented front discs from the GT500 Mustang, unique 19-inch alloy wheels, and summer performance tires.
For 2011, Mustang GT offers drivers several new convenience technologies, including standard message center, integrated blind spot mirrors, MyKey programmable vehicle key, illuminated visors with storage, and universal garage door opener. From the 5.0 fender badges to the new engine cover, the 2011 Mustang GT honors and continues the proud heritage of its predecessors. The speedometer increases to 160 mph and the tachometer redline advances from 6,500 to 7,000 rpm.
Three new colors will be added for 2011 including Yellow Blaze Tri-Coat, Race Red and Ingot Silver.
Mustang GT convertible models feature enhanced structural rigidity, with lateral stiffness improved by 12 percent versus the 2010 model. A tower-to-tower front strut brace is now standard, and the V-brace has been stiffened by adding gussets. The secondary crossmember also has been stiffened while a front Z-brace has been added, connecting primary and secondary crossmembers. A-pillar stiffening foam also has been added to increase rigidity.
