The big news for the 2011 Ford Mustang is new engines across the board. Ford is upping the stakes in the pony car wars with base models getting a 3.7-liter 24-valve Duratec V-6 good for 305 hp. Mustang GT fans celebrate the return of the legendary 5.0-liter V-8 promising 412 hp and 390 lbs-ft of torque. New six-speed manual and automatic transmissions help achieve estimated 30mpg highway for the V-6 and 25mpg highway for the V-8. For even more performance, the 2011 Mustang GT500 receives a new aluminum 5.4-liter supercharged V-8 with 550 hp. All Mustangs continue to be available with Ford’s Sync system, SIRIUS Travel Link, AdvanceTrac RSC, a glass roof, and many more options. With new sheet metal and improved interiors in 2010 combined with upgraded powertrains for 2011, this much improved Mustang was honored to pace the 52nd annual Daytona 500.
