2010 Ford Flex

Ford Flex turns heads with its distinctive design -- and the unique full-size crossover becomes even more noteworthy, thanks to an available twin-turbocharged 3.5-liter EcoBoost V-6 engine. This all-new engine gives Flex V-8 power and performance feel with the fuel economy of a V-6.

The twin-turbocharged 3.5-liter EcoBoost V-6 produces an estimated 355 horsepower at 5,700 rpm and 350 lb.-ft. of torque at 3,500 rpm. The twin-turbocharged 3.5-liter EcoBoost V-6 engine requires all-wheel drive and is available on well-equipped SEL and Limited models of the 2010 Flex, packaged with several high-demand customer features.

The dual-turbocharger setup has several advantages over previous turbocharging systems, including:

The turbochargers are smaller, resulting in more-compact exhaust manifolds, which don't generate as much heat;

Turbochargers are packaged adjacent to the cylinder block and have improved mounting providing NVH (noise, vibration, harshness) improvements;

The dual turbochargers spool up quicker, allowing the 3.5-liter EcoBoost V-6 engine to reach peak torque faster. The turbochargers spin at approximately 170,000 rpm. By comparison, the redline for the engine is approximately 6,500 rpm.

The turbochargers are designed for a life cycle of 150,000 miles or 10 years.
