“These three new engines represent a quantum leap in rounding out a world-class Mustang powertrain portfolio,” Derrick Kuzak, group vice president, Global Product Development said. “Each represents Ford’s commitment to use technology to deliver the performance and fun-to-drive factor customers demand, while continuously improving fuel economy."
The 3.7l V6 engine develops 305 horsepower thanks to the Ti-VCT, which allows variable control of valve operation across the rev range. As a result, the engine provides as much as a 3 percent improvement in fuel economy (30 mpg highway) and a 10 percent improvement in power output when compared to traditional engines.
The 5.0l, 32-valve V8, also with Ti-VCT delivers 412 horsepower and 390 ft.-lb. of torque, while the fuel economy is rated at 25 mpg highway when equipped with the six-speed automatic transmission.
The biggest of them all, the 5.4l supercharged V8, develops a huge 550 horsepower (10 hp more than the outgoing 2010 model) and 510 ft.-lb. of torque. According to Ford, the new engine will make the 2011 Shelby GT500 the first one of its kind to achieve a fuel economy rating which will allow it to avoid gas guzzler tax.
With all the new engines getting ready to hit the streets, Ford had no choice but to develop a new way of harnessing all that power. In consequence, two new transmissions have been developed: a six-speed manual gearbox and a six-speed automatic transmission.
