The first generation of the Volkswagen Type 2 with the split windshield, informally called the Microbus, Splitscreen, or Splittie among modern fans, was produced from 8 March 1950 through the end of the 1967 model year. From 1950 to 1956, the T1 (not called that at the time) was built in Wolfsburg; from 1956, it was built at the completely new Transporter factory in Hanover. Like the Beetle, the first Transporters used the 1100 Volkswagen air-cooled engine, a 1,131 cc (69.0 cu in), DIN-rated 18 kW (24 PS; 24 bhp), air-cooled flat-four-cylinder 'boxer' engine mounted in the rear. This was upgraded to the 1200 – a 1,192 cc (72.7 cu in) 22 kW (30 PS; 30 bhp) in 1953. A higher compression ratio became standard in 1955; while an unusual early version of the 30 kW (41 PS; 40 bhp) engine debuted exclusively on the Type 2 in 1959. Any 1959 models that retain that early engine today are rare. Since the engine was discontinued almost immediately, no spare parts were made available.
