The Bronco Raptor will likely be V6-powered
Don't expect Ford to follow the Jeep Wrangler 392 down the V8 rabbit hole. The Bronco Raptor should counter with V6 power.
The Bronco Nation's most recent batch of info suggests the truck will stick with an upgraded version of the 2.7-liter twin-turbo V6 that's optional in the regular Bronco, potentially making close to 350 horsepower. But that's hardly the only engine they could put under the hood.
Another option would be the twin-turbocharged 3.0-liter V6 that puts 400 hp and 415 lb-ft of torque in the Explorer ST — and which has an even more powerful hybrid variant in the Lincoln Aviator Grand Touring. Ford could also say screw it and give the Bronco Raptor the full-bore twin-turbo 3.5-liter V6 with 450 hp and 510 lb-ft from the F-150 Raptor. Either way, expect a 10-speed automatic transmission.
