Looks like a close copy of the Tacoma, which isn't a bad thing.
It uses a second-generation 2.3-liter twin-scroll turbocharged four-cylinder EcoBoost engine with a forged steel crankshaft and a new 10-speed automatic transmission - 280 hp / 310 lb-ft of torque in the same engine as the Explorer.
It's got a steel, not aluminum skin:
