The newly redesigned 2015 Ford Mustang offers three powerful, fuel-efficient engines. On the road, its smooth ride and responsive handling give it the edge over the Challenger. The Mustang's standard 3.7-liter V6 delivers 300 horsepower and 280 pound-feet for swift acceleration. The EcoBoost model comes with a turbocharged 2.3-liter four-cylinder engine that makes 310 horses and 320 pound-feet of torque. The EcoBoost engine offers the line's best EPA ratings. Paired with the manual transmission, the EcoBoost achieves 22 city/31 highway mpg. The automatic transmission changes those ratings slightly, to 21/32 mpg. Finally, the Mustang GT's 5.0-liter V8 generates an incredible output of 435 horses and 400 pound-feet of torque. It's a great choice for drivers who crave incredible speed.

The Dodge Challenger's standard V6 engine delivers 305 horses. Shoppers can also choose from two powerful V8 engines, a 5.7-liter Hemi and a 6.4-liter V8.

With this engine, the Challenger goes from zero to 60 in just 4.5 seconds. New for 2015 is a special SRT Hellcat model. Its supercharged 6.2-liter V8 makes a beastly 707 horses and 650 pound-feet of torque.
