The Tacoma is offered in six trim levels: SR, SR5, TRD Sport, TRD Off-Road, Limited and TRD Pro. The SR extended cab has a 6.1-foot bed or a crew cab with a 5-foot bed, and you can choose between rear-wheel drive or part-time four-wheel drive with a low-range transfer case. Its 2.7-liter four-cylinder engine is paired to a six-speed automatic transmission. Other standard equipment for the SR includes 16-inch steel wheels, a sliding rear window, heated power-adjustable side mirrors, a tough composite bed that needs no bedliner, and a movable cleat tie-down system. Inside, there are manual front seats, cloth upholstery, a Wi-Fi hotspot, a 7-inch touchscreen, Apple CarPlay and Android Auto, and a six-speaker audio system. As with other Toyotas, the Tacoma comes standard with many advanced driving aids, including forward collision warning with automatic emergency braking, lane departure alert, automatic high beams, and adaptive cruise control. The SR5 gets a long-wheelbase version that pairs the crew cab with the 6.1-foot bed. On the outside, you get some chrome exterior trim, remote keyless entry, a leather-wrapped steering wheel, and an 8-inch touchscreen.
