Ford engineers drew from their extensive experience using direct injection technology and turbocharging in diesel engine development and created the innovative EcoBoost® engine option that's unsurpassed in combined power, efficiency and capability. Direct injection produces a cooler, denser charge that generates more power per every drop of fuel, while the two small air-to-air intercooled turbochargers spool up much more quickly than a single large turbo. What you experience is instantaneous low-end torque responsiveness with virtually no turbo lag. EcoBoost generates 90 percent of its amazing 420 lb.-ft. of torque from 1,700 to 5,000 rpm. And can it tow? F-150 with EcoBoost has best-in-class maximum towing capability at 11,300 lbs.** Best-in-class payload, too, at 3,060 lbs.** The EcoBoost engine underwent over 1,900 hours of testing at full-boost conditions, as well as thermal testing to simulate 10 years of operation in the harshest environments. So EcoBoost is up to any task you can give it ? and then some.
