New 2015 Ford Mustang gets 3 engines, led by 435-hp V8

By ,

Ford today announced the three engines that will be available with the all-new 2015 Mustang when it goes on sale at the end of this year.

The standard unit will be a 300-horsepower, naturally aspirated V6, which is a familiar unit in the Mustang range.

Customers will also have the option of a brand new 2.3L 4-cylinder EcoBoost engine that's turbocharged and direct injected to produce 310 horsepower and 320 lb-ft of torque -- the best-ever power density from a Ford engine.

“This EcoBoost engine delivers the healthy output Mustang drivers expect, regardless of the car’s speed,” said Scott Makowski, EcoBoost powertrain engineering manager. “It delivers where a Mustang driver expects it to -- with a broad, flat torque curve and great driveability under any conditions.”

Of course, let's not forget the almighty 5.0L V8 at the top of the range. This one boasts 435 horsepower and 400 lb-ft of torque, as well as an improved power-to-weight ratio. It benefits from a host of upgrades that can be credited to the development of the special-edition 2012 Mustang Boss 302, including:
  • Larger intake and exhaust valves;
  • Revised intake and exhaust camshafts
  • Stiffer valve springs ensure valves close completely at high rpm;
  • New cylinder head casting;
  • Sinter forged connecting rods are lighter and more durable;
  • Redesigned piston tops;
  • Rebalanced forged crankshaft to support higher-rpm operation;
All three engines can be mated to a 6-speed manual or automatic transmission, the latter featuring SelectShift paddle shifters.
