A new Proceed/B series (UF) was introduced in January 1985; it was produced until June 1999. A five-speed manual transmission was the primary choice in most markets, with options of a four-speed automatic transmission option and part-time four wheel drive. The 2.6-liter, Mitsubishi-powered B2600 was added in 1986. 1987 saw the Mazda inline-four engine upgraded to 2.2-liters in the B2200; the smaller engine was phased out of the North American markets after that year. In 1988, the Mitsubishi engine was replaced with a new family of Mazda powerplants. This generation also returned to the Japanese market as the "Proceed", where it was marketed mostly as a "lifestyle" truck.
