Just what I read, and haven't read this before anywhere. Maybe the rumor of 511 hp can be true after all, if the 755 hp of the GT is to be believed: The next-generation 3.5 L EcoBoost V6 is being produced for the 2017 Ford GT, revealed at the 2015 Detroit Auto Show in January. It will produce 755 horsepower (outpowering the twin-turbo V8-powered McLaren P1 without electric motors) and 690 lb-ft of torque, paired with a 7-speed semi-automatic transmission. This engine theoretically replaces the 5.4 L Supercharged Modular V8 from the last generation Ford GT which produced 550 horsepower. The GT has been on a 10-year hiatus, and will return in 2016 for the 2017 model year. Also announced at the 2015 Detroit Auto Show was the 2017 Ford F-150 SVT Raptor, which is powered by an all-new 3.5 L twin-turbocharged EcoBoost V6. This new engine is expected to produce between 450 and 500 horsepower in the Raptor, up from the previous 6.2 L V8's 411. Torque is also expected to higher than the 434 lb-ft produced by the naturally aspirated 6.2 L Boss V8.
