Volkwagen T1 Bus Splitscreen
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 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, an 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 – an 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.
This engine proved to be so uncharacteristically troublesome that Volkswagen recalled all 1959 Transporters and replaced the engines with an updated version of the 30 kW engine. Any 1959 models that retain that early engine today are true survivors. Since the engine was totally discontinued at the outset, no parts were ever made available.
