The new Raptor will see its EcoBoost engine creating 450 hp and 510 lb-ft of torque. These power figures are much higher than the V8's rating of 411 hp and 434 lb-ft of torque.

“Raptor was designed to be a no-compromise, off-road performance machine,” said Matt Tranter, Ford Performance engineering supervisor, in the press release. “That is why we made the switch from the cast-iron V8 to the aluminum block, high-output GTDI V6 EcoBoost engine that our team tuned to add 39 horsepower and 76 lb.-ft. of torque for today’s Raptor.”
As far as a top speed or acceleration goes, Ford hasn't said a word. But with trucks durability and power is typically more important than its speed. Ford will be selling the truck with a base MSRP that's less than $50,000.
