Test Drive: 2015 Ford F-150 FX4 EcoBoost - Autos.ca
But the new F-150’s newly-available little six uses twin turbochargers instead of more, larger cylinders, generating 325 horsepower and a manly 375 lb-ft of torque. When you leave the trailer at home and you’re just going to Sears, cruising the highway in no particular rush, or inching slowly through the Timmies drive-thru, engines like this one burn less gas in their smaller, fewer cylinders. Call it EcoBoost, twin-turbo, or whatever you like, but the principle is the same: off-loading power output to a turbocharger system lets engines drink less, more of the time. Drive gently, and the twin compressors quietly whistle and hiss the F-150 along from low revs, with minimal hunting for a lower gear, thanks to the mountain of torque available from right above idle. Remember: torque is the important figure when you’re moving something heavy, and this new little EcoBoost engine has heaps of it, from really, really low revs. And this is the little EcoBoost V6: a bigger one is available, with 3. 5 litres and twin-turbo making it 365 horses and over 400 lb-ft of off-idle torque.
