New engines for the 2015 Ford F-150 pickup truck start with a high-output 2.7-liter EcoBoost with standard Auto Start-Stop. It provides mid-range V8-like towing capability of 8,500 lbs. and payload of 2,250 lbs. The new EcoBoost is 23% smaller than the 3.5-liter EcoBoost introduced in 2011, but its 325 hp is 91% of the original power and 375 lb.-ft. of torque is 89% of the 3.5-liter EcoBoost's torque.

F-150 V6 EcoBoost Matches Super Duty V8 Towing Capacity

Specially tuned for truck customers, Auto Start-Stop shuts off the engine when the vehicle is at a stop. When the brake is released, the engine restarts quickly. Auto Start-Stop helps reduce fuel consumption and emissions when the truck is stopped and the engine is off. The technology is off when towing or in four-wheel-drive mode.

The 2.7-liter EcoBoost engine also features Ford’s first use of a compacted graphite iron cylinder block in a gasoline engine, the same material used in Ford’s 6.7-liter Power Stroke turbo diesel V8 in Super Duty trucks. The composite CGI/aluminum cylinder block saves weight while providing strength where it’s needed most for durability.

The second engine being introduced is a standard 3.5-liter V6 engine with twin independent variable camshaft timing delivers 283 hp and 255 lb.-ft. of torque with towing of 7,600 lbs. and 1,910 lbs. of payload. Use of high-strength steel and high-strength, military-grade, aluminum alloy plus smart engineering saves up to 700 lbs., improving power-to-weight ratio and allowing for gains in towing, performance and efficiency.

The standard 3.5-liter V6 with Ti-VCT offers a 5 percent improvement in power-to-weight ratio over the larger 3.7-liter V6 in the 2014 F-150, with better fuel efficiency and performance. The 24-valve 3.5-liter V6 features a valvetrain with direct-acting polished mechanical buckets with twin independent variable camshaft timing for impressive torque across a wide rpm range. Six-bolt main bearing caps, a fully counterweighted forged steel crankshaft and cast exhaust manifolds are designed for heavy-duty operation.

The other two available engines include the 5.0L V8 and 3.5L EcoBoost V6 that were offered on the previous generation F-150.
