On sale in March 1996, 4Runner shared powertrains and some chassis elements with the Tacoma pickup, but styling, wheelbase, rear suspension, and interior design differed. Dual airbags were standard, along with 4-wheel antilock brakes and side-impact door beams. Wheelbase was two inches longer, door width grew by 1.5 inches, rear leg room was up three inches, and the floor was lowered by 2.4 inches. A new one-piece rear liftgate replaced the former 2-piece tailgate, with a standard power window. The 4-door wagon came with 2- or 4-wheel drive in base, sportier SR5, and luxury 4WD Limited trim. Base engine was a 2.7-liter 4-cylinder. Standard in the Limited and optional in others was a 183-horsepower, 3.4-liter V6. A 5-speed manual gearbox was standard, 4-speed automatic optional (standard on Limited). All 4x4s except the Limited used a part-time 4WDemand system. Only Limiteds got Toyota's electronic One-Touch Hi-4 system, with a handy button on the transfer-case lever to shift between 2WD and 4WD High range.
