3.5 EcoBoost (Gen 1)

The 3.5 Ecoboost is a Ford engine that was first introduced to the market in 2007 in the “TwinForce” Lincoln MKR concept vehicle. The 3.5L Ecoboost is engineered to provide similar power and torque as the V8 6.0L engines and improving the fuel efficacy by 15% at the same time.

This first TwinForce engine delivered 415 hp (309 kW) and 400 lb-ft (542 Nm) of torque, and it used E85 fuel. The name was changed from TwinForce to Ecoboost in 2008 when the Lincoln MKT was introduced using the TwinForce name. In 2009, the Ecoboost started official production.

The 3.5L Ecoboost is based on the Duratec 35 V6 engine block, and this model provides high fuel pressures up to 2150 psi through its fuel charging and delivery systems.

Two BorgWarner K03 turbochargers are integrated into the F-series EcoBoost 3.5L V6 model, and these can spin up to 170,000 rpm, providing up to 15 psi of boost.

The transverse EcoBoost 3.5L V6 comes with two Garrett GT1549L turbochargers set up in a twin-turbo configuration; these deliver up to 11 psi of boost. This engine model consumes 25% more air over standard models and runs on standard fuel.

The EcoBoost V6 started to appear in the 2010 Lincoln MKS, then in the 2010 Ford Flex, 2010 Ford Taurus SHO, and 2010 Lincoln MKT.

3.5 L EcoBoost (Gen 2)

The next-generation model of the 3.5 EcoBoost is the 3.5 L Ecoboost model, and it first appeared in the 2017 Ford GT. This model delivers 647 hp (482 kW) and comes paired with a seven-speed semiautomatic transmission.

At the same time, Ford presented the 2017 Ford F-150 SVT Raptor; this uses the 3.5 L twin-turbocharged EcoBoost V6, which delivers 450 horsepower in the Raptor outperforming its 6.2-L V8’s 411HP performance.

The 2nd Gen 3.5 L EcoBoost is replacing all F-150 engines from 2017 and onwards, and these models now come with the 10R80 10-speed automatic transmission.
