2017 Ford F-150 Gets 1 MPG Bump With Updated Engine, 10-Speed Transmission

Gains of 10 hp and 50 lb-ft of torque, to boot

EPA fuel-economy figures for the 2017 Ford F-150 are out, and as promised, the Blue Oval has delivered with improved efficiency and performance for its 3.5-liter EcoBoost V-6 engine. Despite gains of 10 hp and 50 lb-ft of torque, now totaling 375 hp and 470 lb-ft, the new  F-150 3.5-liter EcoBoost sees improvements of 1 mpg in both city and highway scenarios, for both rear- and four-wheel-drive models.

The 2017 Ford F-150 3.5-liter EcoBoost is now rated at 18/25 mpg city/highway in rear-drive form, and 17/23 mpg city/highway with four-wheel drive.

As we learned back in May, these improvements are the result of an all-new 3.5-liter twin-turbo V-6 and a new 10-speed automatic transmission, the latter co-developed with General Motors. Aside from the all-new engine block, heads, and turbochargers, a big upgrade from the old 3.5-liter is the addition of port fuel injection working alongside direct injection.

The 10-speed automatic transmission, also used in the upcoming F-150 Raptor, contains less friction and offers more ratios as well as overdrive for the top three gears.  Stop-start is also standard.

Other destinations for the 10-speed automatic are possible within the Ford lineup, most notably in the 2018 Ford Mustang. (Chevrolet already announced its version is going in the Camaro ZL1.) Expanded use of the transmission would both pad CAFE numbers as well as justify the $1.4 billion investment Ford made in its Livonia Transmission Plant last April.
