Ford provides some performance specs for its new 2.7L twin-turbo EcoBoost for the MY2015 F-150

The MY 2015 Ford F-150 will offer a new high-output, twin-turbo 2.7-liter EcoBoost V6 producing 325 hp (242 kW) and 375 lb-ft (508 N·m) of torque. Due to the extensive lightweighting in the new F-150 (earlier post), this will improve the power-to-weight ratio of the 2015 truck by 15% over the 2014 5.0-liter V8-equipped F-150 with similar torque output.

Boosting 2.7-liter EcoBoost fuel efficiency is the debut of standard Auto Start-Stop technology for F-150. The technology is off when towing or in four-wheel-drive mode. The 2.7-liter EcoBoost 4x2 has a maximum payload rating of 2,250 lbs (1,021 kg) and maximum tow rating of 8,500 pounds (3,856 kg), suited for meeting mid-range capability needs.

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 2.7-liter EcoBoost engine features the 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 engine. The composite CGI/aluminum block saves weight while providing strength for durability.

The 2.7-liter EcoBoost also features all-new engine logic that adjusts operating parameters on the fly to provide the best efficiency and performance for the environment and workload. Other new features of the 2.7-liter EcoBoost include:

  • First use of fracture split main-bearing caps, which create a superior fit between the cap and engine block for reduced crankshaft friction to help improve efficiency.

  • All-new aluminum cylinder heads feature water-cooled integrated exhaust manifolds.

  • Variable displacement oil pump reduces internal engine friction to improve fuel economy.

  • Intake and exhaust variable cam timing that improves torque while helping lower emissions.

  • Lightweight, durable composite intake manifold.

  • Cooling jets beneath the pistons that spray oil on the pistons to help lower operating temperatures.

  • Piston connecting rods use an offset I-beam that provides strength to manage peak engine power levels while reducing weight for better responsiveness.

  • Cartridge-style oil filter integrated into top of the engine for easy service.

Leveraging all this, the new 2.7L EcoBoost offers more than twice the horsepower, torque and towing capability of the Toyota Tacoma midsize pickup truck with identical displacement 2.7-liter four-cylinder engine.

Ford testing shows the 2.7-liter EcoBoost also outperforming Ram 1500 3.0-liter V6 EcoDiesel and Chevrolet Silverado 1500 5.3-liter V8 while towing a 7,000-pound enclosed trailer up Davis Dam in Arizona. This is the same grade the Society of Automotive Engineers uses for its J2807 towing testing standards, which the 2015 Ford F-150 will follow.

3.5-liter V6. Again due to vehicle weight savings, the standard 3.5-liter V6 with Ti-VCT offers a 5% 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 3.5-liter V6 produces 283 hp (211 kW) and 255 lb-ft (346 N·m) of torque. The engine has a maximum payload of 1,910 pounds (866 kg) and a maximum tow rating of 7,600 pounds (3,447 kg)—unsurpassed for standard V6 light-duty pickup trucks.

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.

Both the upper and lower intake manifolds of the 3.5-liter V6 are tuned for responsive power, and both the intake manifolds and cam covers are composite-formed to reduce weight. The die-cast aluminum cylinder block features bay-to-bay breathing to reduce internal pumping losses, while a deep-sump oil pan contributes to extended oil-change intervals.

Extensive research by Ford engineers led to the use of more advanced materials on the 2015 F-150 than found in previous trucks. Military-grade aluminum alloys make the new truck’s body lighter, stronger and more resistant to dents. Overall, F-150 is up to 700 pounds (318 kg) lighter.

In addition to the new V6 engines, the all-new 2015 F-150 offers the proven 3.5-liter EcoBoost and the 5.0-liter V8 with Ti-VCT.
