Late last year, Ford threw the sheets off the design for its 2015 Mustang. Now the automaker has revealed what will lie under the hood of that updated body, including more powerful V6 and V8 engines, along with a new EcoBoost engine that the company says boasts the best power density ever for a Ford engine.
The base engine available on the 2015 Mustang is a naturally aspirated, 300 hp (223 kW) V6, however, the flagship of the range steps things up to a 5.0-liter V8 pumping out 435 hp (324 kW) and providing 542 Nm of torque. The V8 takes advantage of larger intake and exhaust valves, and Ford says its forged crankshaft has been rebalanced to make the engine better at high revs.
While the V8 may top the Mustang lineup, the turbocharged four cylinder EcoBoost engine is big news as well. Designed specifically for the Mustang, the 2.3-liter engine includes direct fuel injection and twin independent variable camshaft timing and puts out 310 hp (231 kW) and 433 Nm of torque. This gives it what Ford says is the best ever power-density for one of its engines, with a specific output of almost 135 hp (101 kW) per liter and more than 188 Nm of torque per liter. The engine has also been strengthened to withstand the added stresses placed on it to ensure durability.
All three engines are available with either a Getrag six-speed manual or Ford's "SelectShift" six-speed auto. The manual is meant to be more precise than the gearbox in the old Mustang thanks to a redesigned shift linkage, while the shift lever has been shuffled closer to the driver and away from the cupholders. Meanwhile, the automatic gearbox comes standard with rev-matching on downshifts and drivers able to take manual control with wheel-mounted paddles.
The new Mustang will go on sale in the US later this year.
