The outgoing SVT Raptor’s 6.2-liter V-8 has been replaced with the second-generation 3.5-liter EcoBoost V-6. While power ratings for the 2017 F-150 Raptor’s EcoBoost haven't been announced, the automaker says it will be more powerful and more efficient than the old 6.2-liter V-8 engine’s 411 hp and 434 lb-ft of torque rating. In the regular 2015 Ford F-150, the 3.5-liter EcoBoost makes just 365 hp and 420 lb-ft. The Raptor's EcoBoost engine exhales through a new dual exhaust and is backed by an all-new 10-speed automatic, which should further improve performance and efficiency.
