Both trims have electronic-shift-on-the-fly four-wheel drive and low-range gearing for towing and off-road capability. Power is delivered from a 207 hp 4.0-liter V-6 mated to either a five-speed automatic or five-speed manual transmission. Its raised suspension uses torsion-bar front springs. Rear-hinged back doors are unique to the Cab Plus. The Base trim comes with 15-inch steel wheels while the SE gets 16-inch alloy wheels.The Mazda B4000 is a carryover from 2007 with some minor standard equipment changes.
