VW Transporter T4 1990-2003

Introduced in 1990, the T4 was the first Volkswagen van to have a front-mounted, water-cooled engine. Prompted by the success of similar moves with their passenger cars, Volkswagen had toyed in the late 1970s with the idea of replacing their air-cooled, rear-engined T2 vans with a front-engined, water-cooled design.
The reasons for deciding in 1980 to instead introduce a new rear-engined T3 are unclear. Thus, the introduction of a front-engined layout was delayed until the arrival of the T4.
