The B4000 is available in only one body style, Cab Plus 4-door. It has two trim levels: base and SE. Both trims have four-wheel drive and low-range gearing for towing 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. It comes with either 15-inch wheels for the base or 16-inch for the SE.For 2007, the Mazda B4000 is largely a carryover, but it does receive a new tire pressure monitoring system.
