Ford 3.5L EcoBoost V-6

3.5L EcoBoost Specs and Information

The 3.5L EcoBoost V-6 was first introduced to the F-150 lineup for the 2011 model year. At the time of its inception, there was much skepticism regarding Ford's efforts to market the 213 CID V-6 as the backbone of the best selling F-150; the engine continues to carry the model lines highest towing capacity. All things considered, the EcoBoost has been a tremendous success for Ford Motor Company and the engine's performance characteristics exceed that of even most competitor's V-8 engines. Twin parallel mounted turbochargers are employed to compensate for the engine's relatively small displacement, which provide on-demand power as needed, but without compromising fuel economy under less demanding conditions. Ford boasts that the engine maintains 90% of peak torque from 1,700 to 5,000 rpm, an attribute that no competing manufacturer can claim.

While Ford recommends the use of premium 91 octane gasoline to maximize performance, the engine is entirely compatible to run on regular 87 octane fuel despite its relatively high compression ratio. This is made possible by a direct injection system, which eliminates the risk of detonation by injecting fuel directly into the compression chamber at the moment that combustion is desired. For the revised 2017 EcoBoost, both multi-port and direct injection types are utilized but the fuel requirements remain unchanged.

The EcoBoost's key design principle is its forced induction, allowing the relatively small engine to exhibit performance characteristics meeting or exceeding that of a much higher displacement engine. When there is a need for power, such as heavy acceleration or towing, the turbocharger's extra airflow compensates for the EcoBoost's displacement handicap. Under lighter loads, fuel economy is maximized while the turbochargers produce little to negligible boost. As a result of 3.5L EcoBoost's success, Ford introduced an even smaller 2.7L EcoBoost capable of greater fuel economy for the 2015 model year.

2017 Model Year EcoBoost Changes, Upgrades, & Improvements

For the 2017 model year, a more powerful 3.5L EcoBoost was introduced to the F-150 lineup. The engine, which underwent a number of changes and upgrades, produces a peak 375 horsepower @ 5,000 rpm and 470 lb-ft @ 2,500 rpm. In addition to engine's significant performance growth, the EcoBoost equipped F-150's fuel economy ratings were increased across the board. A high output version producing 450 horsepower and 510 lb-ft of torque is available exclusively in the 2nd Generation Ford Raptor.

• Start-stop technology becomes standard on all 3.5L EcoBoost engines. The start-stop system deactivates when Tow/Haul function or 4 wheel drive is in use.

• New turbocharger with low mass, turbine wheel constructed from MAR-M-247 super alloy designed to significantly reduce turbocharger lag. Turbochargers use electrically actuated wastegate.

• 4 cores removed from each camshaft, reducing rotating assembly weight.

• 10R80 ten speed automatic transmission introduced exclusively to 3.5L EcoBoost powered F-150 and Raptor.

• High output 3.5L EcoBoost standard for F-150 Raptor model line.

• Sound deadening engine cover introduced.

• Direct and multi-port fuel injection utilized - previous engine featured direct injection only.

• Compression ratio increased from 10.0 : 1 to 10.5 : 1 (excluding H.O.).
