The Tacoma is powered by either a 2.7L 4-cylinder that makes 159 horsepower, or by a 3.5L V6 that makes 276 horsepower. Transmission options are either a 6-speed manual or 6-speed automatic, with power sent to the rear wheels, though four-wheel drive is optional. The Tacoma is offered with a wealth of customization options but it comes in six trims: SR, SR5, TRD Sport, TRD Off-Road, Limited and TRD Pro. The base SR version can be ordered with either the Access Cab, or with the 4-door Double Cab. The Access Cab comes with a standard length bed, while the Double Cab is only available with the short bed. Standard equipment includes 16-inch wheels, power windows and door locks, a backup camera, an Entune audio system with Bluetooth connectivity and a deck rail system to help secure loose objects in the bed. The SR5 allows buyers to choose both the bigger cabin and the longer bed. SR5s include keyless entry, a 4.2-inch multi-information display in the instrument cluster, SiriusXM satellite radio, fog lamps and a bit more chrome on the exterior of the truck. The TRD Off-Road version adds both style and off-road utility to the Tacoma. Special 16-inch wheels look mean and stylish while functional additions include a locking differential, crawl control and a multi-terrain select driving aid. Options on the TRD Off-Road include dual-zone climate control and a sunroof. The bigger V6 engine is standard. Where the TRD Off-Road is rugged, the TRD Sport is slick and stylish. Like the TRD Off-Road, the TRD Sport is only available with the V6 engine. Wheels are 17-inch alloys, while the interior gets a premium sound system and a wireless smartphone charger. The bed features a 120V outlet while the daytime running lights use ultra-bright LEDs. A smart key is also standard on the TRD Sport. The Limited comes only with the larger cabin and a V6. It adds color-keyed bumpers and additional exterior chrome, polished 18-inch wheels, automatic climate control, a powered moonroof and heated, leather-trimmed seats. Finally, the TRD Pro offers LED headlights, 16-inch TRD Pro Black alloy wheels, unique exterior grille, badging, and hood scoop, leather-trimmed seats with a special headrest logo, a power sliding rear window with privacy glass, dual-zone automatic climate control, and blind-spot monitor with rear cross-traffic alert. Standard off-road technologies include an electronically locking rear differential, front skid plate, FOX internal bypass shocks, a cat-back exhaust, multi-terrain selection and crawl control.
