Toyota Tacoma is available in Regular Cab, Access Cab (extended cab) and Double Cab (crew cab) body styles, in either two or four wheel drive. Regular and Access Cabs come with six-foot beds; Double Cabs have the choice of a shorter five-foot bed or a standard-size six-footer. The base engine is a 2.7-liter, 159-hp inline-four mated to a five-speed manual transmission; a four-speed automatic is optional. A 236-hp 4.0-liter V6 is standard on all Double Cabs and optional on 4WD Access Cabs. The V6 is paired with a six-speed manual or five-speed automatic. Standard safety features include four-wheel anti-lock brakes with electronic brake-force distribution and brake assist, vehicle stability control, traction control, side-impact/side curtain airbags, and active headrests. For 2009, the Toyota Tacoma adds traction control, stability control, side impact and curtain airbags, LED taillamps, auxiliary audio input, and mp3 player as standard equipment.
