Here’s the latest reader question, along with my reply!
Mark asks: How about 360 hp, 500 ft.-lb. of torque from a 2.7 liter gas engine that gets 35+ mpg? Have you seen or heard about this?
My reply: The current (2019) F-150 does offer a 2.7 liter “EcoBoost” V6 with twin turbos, but it only makes 325 horsepower and carries an EPA mileage rating of 19 city/24 highway (4WD versions). I have driven this truck and can report it averages high teens unless driven with a very light foot.
I hugely doubt a 360 hp version would be capable of matching the EPA’s rosy numbers – and forget “35+” MPG.
A diesel engine might be able to get close to 30 . . . on the highway. But with a gas engine, this is very improbable.
You can’t have your cake (power/capability) and eat it, too (high mileage). Usually, one or the other thing has to be compromised.
A 1500 Series truck like the F-150 is expected to be capable of things such as pulling/carrying a heavy load, which is at odds with high gas mileage.
Mileage can be increased – without compromising capability – if you’re willing to accept higher cost for the vehicle itself. For example, aluminum rather than steel bodies; small/highly turbocharged engines; transmissions with multiple overdrive gears; direct-injection/cylinder deactivation/auto-stop/start… and so on.
But now you’ve spent more money on the vehicle than you’ve saved on gas.
Aye, there’s the rub!
