3.5L EcoBoost V-6

Ford EcoBoost Specs

 

 

 

 

 

Ford introduced the 3.5L EcoBoost V-6 to the F-150 pickup line for the 2011 model year. The engine uses twin, parallel mounted turbochargers, which more than compensate for the engine's relatively small displacement. At 213 cid, the EcoBoost outperforms the standard 5.0L V-8 in both horsepower and torque, while providing a significant increase in fuel economy. The engine is rated at a maximum 365 horsepower and 420 lb-ft of torque, and maintains 90% of peak torque from 1,700 rpm to 5,000 rpm. Four wheel drive models can achieve up to 21 mpg on the highway, while two wheel drive pickups are rated at a slightly higher 22 mpg. Direct injection, similar to that used in diesel engines, allows for a 10:1 compression ratio and the use of regular, low octane gasoline without the risk of detonation.

 

The engine's performance characteristics prove that forced induction can be a replacement for displacement - power when you need it, and fuel economy when you don't. While there was some skepticism when the engine debuted, its popularity can be deemed a success for Ford, who has employed extensive resources in the development of the EcoBoost engine family platform. You wouldn't expect the EcoBoost to be the backbone of the F-150 engine lineup, but that's exactly what it is; the EcoBoost carries the F-150's highest tow ratings, and is the engine Ford highly recommends for the tougest tasks. There have been little problems with the EcoBoost, save for some incidents in which condensation build up in the intercooler has caused driveability concerns (stalling, bucking, loss of power). These cases are believe to be isolated incidents, and are generally not of concern to owners. With the EcoBoost, Ford has proven that you can indeed get more from less. The sucess of the 3.5L EcoBoost has led Ford to develop a smaller 2.7L version for the 2015 F-150, which aims to increase fuel economy without making significant sacrifices in performance.

• Despite being a high compression, forced induction engine, the direct injection fuel system allows the EcoBoost to run on 87 octane, regular unleaded gasoline.
• The EcoBoost maintains 90% peak torque between 1,700 - 5,000 rpm (90% of 420 lb-ft is 378 lb-ft). Such flat torque curves are extremely uncommon of a production gas engine.
• Properly equipped, an EcoBoost powered F150 can tow up to 11,300 lbs, the maximum tow rating for any 2011 - 2014 model F-150. In fact, Ford is actually recommending the EcoBoost for those who require the ability to tow frequently as it is more efficient than the available V-8 engines.

• Direct injection systems spray pressurized fuel directly into the combustion chamber rather than into the intake ports (the traditional injection method). A more precise delivery of fuel is accomplished by injecting directly into the combustion chamber, eliminating the chances of detonation (knocking) and increasing efficiency, performance, fuel economy, & lowering emissions.
