Defined by the first turbo 4 cylinder motor to be found the Mustang’s hood since the 1986 SVO and the overly impressive 305 horsepower it squeezes out of a mere 2.3 liter engine, the new 2015 EcoBoost Mustang is a game changer.
Some argue a 4 cylinder doesn’t belong in a Mustang and others call it natural progression, but regardless of which side of the fence you’re on, the 4 cylinder Mustang is here to stay. One thing there’s no arguing about is that it does have Mustang worthy power–the all-new 2.3L EcoBoost 4 cylinder is said to pump out a startling 305HP, 300LBS of torque and will likely weigh less than the 2015 GT and base model V6. That’s 5 more horsepower than the base model V6 will have, and with its turbocharged nature, there’s no denying that some will find ways to increase its power output well past factory rated levels.
There’s also no denying that Ford is as committed to the 4 cylinder as the 6th generation Mustang will be sold in overseas markets. There’s also no guarantee they’ll be offering all three motors to our friends across the way–upon trying to confirm or rebut this, Ford’s Social Media Manager Scott Monty did not offer any information on which motors would be offered overseas, leading one to believe they would be excluding at least one offering from the lineup, most likely the V6. The European market is also supposed to receive a “stiffer suspension” setup than their US counterparts, according to Ford’s Chief Engineer Frank Davis. Davis also declared the V6 a US-only offering.
For those curious as to where outside the US the Mustang will be sold, see the map below:
As for performance, the 4 cylinder shares many of its bells and whistles with the GT if not as a standard feature, as an optional performance package upgrade.
