Buried deep within the UAW document was also word of an all-new, small displacement V-6 to be built at Ford’s Lima, Ohio engine plant. That’s what we know as fact, but it’s fairly easy to speculate on a few details.
As an all-new engine, it will surely come with fuel saving and power-boosting technologies such as gasoline direct injection and variable valve timing. We’d expect Ford to produce an EcoBoost version of the engine as well, since Ford has had great success with the EcoBoost engine range to date.
Car and Driver takes it one step further, guessing that the new V-6 will displace between 2.5 and 3.0 liters, and will make as much as 300 horsepower in EcoBoost trim. That slots it in between the 247 horsepower, 2.0-liter I-4 EcoBoost engine used in the Ford Focus ST and the 365 horsepower, 3.5-liter V-6 EcoBoost engine used in the Ford F-150 EcoBoost.
The question remaining, then, is whether the new V-6 will replace the current 3.5 and 3.7-liter V-6 engines, as suggested by Viknesh Vijayenthiran on MotorAuthority, or simply supplement them. We suppose that decision will be made once details of the new engine’s power output and fuel economy are known.
