The first generation of the Toyota 4Runner was introduced for the 1984 model year and was available until 1989. It was available as a 2 door model only, in multiple trim levels (SR5, DLX, others), but it is now more commonly characterized by its multiple powertrain combinations, some of which overlapped during production. At its launch, it was introduced powered by the 2.4L Toyota 22R inline-four carbureted engine paired to a 5-speed manual transmission. In 1985 the 2.4L 22R-E (now fuel injected) was introduced along with manual and automatic transmission options. A further evolution was the 2.4L turbocharged 22R-TE, available between 1986 and 1987 with automatic transmission only. Finally between 1988 and 1989 Toyota introduced the 3.0L 3VZ-E V6 in both manual and automatic variants. The 1st gen 4Runner was replaced for model year 1990 with the 2nd generation 4Runner.
