The Volkswagen Type 2(T1), known officially (depending on body type) as the Transporter, Kombi or Microbus, or, informally, as the Bus (US), Camper (UK) or Bulli (Germany), is a forward control light commercial vehicle introduced in 1950 by the German automaker Volkswagen as its second car model. Following – and initially deriving from – Volkswagen's first model, the Type 1 (Beetle), it was given the factory designation Type 2.

The concept for the Type 2 is credited to Dutch Volkswagen importer Ben Pon. It has similarities in concept to the 1920s Rumpler Tropfenwagen and 1930s Dymaxion car by Buckminster Fuller, neither of which reached production. Pon visited Wolfsburg in 1946, intending to purchase Type 1s for import to the Netherlands, where he saw a Plattenwagen, an improvised parts-mover based on the Type 1 chassis, and realized something better was possible using the stock Type 1 pan. He first sketched the van in a doodle dated 23 April 1947, proposing a payload of 690 kg (1,520 lb) and placing the driver at the very front. The sketch is now in the Rijksmuseum.

Unlike other rear engine Volkswagens, which evolved constantly over time but never saw the introduction of all-new models, the Transporter not only evolved, but was completely revised periodically with variations retrospectively referred to as versions "T1" to "T5" (a nomenclature only invented after the introduction of the front-drive T4 which replaced the T3). However, only generations T1 to T3 can be seen as directly related to the Beetle.

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, 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. Any 1959 models that retain that early engine today are rare. Since the engine was discontinued almost immediately, no spare parts were made available.

The Volkswagen Samba, in the United States marketed as the Sunroof Deluxe, was the most luxurious version of the T1. Volkswagen started producing Sambas in 1951.

In the US Volkswagen vans were informally identified by the window count. This particular model had 23 and later 21 windows including eight high windows in the roof. The 23-window variant also had curved windows in the rear corners. To distinguish it from the normal Volkswagen van, the name Samba was coined.

The Samba had bi-parting doors in lieu of a sliding door, and could be ordered with a large fabric sunroof. Volkswagen advertised the Samba for making tourist trips through the Alps.

Standard paint finishes on the Samba were two-tone, usually with the upper bodywork in white. The lower bodywork carried a contrasting color, the areas separated by a decorative strip. The roof carried slightly forward of the windshield at the front, creating an integral visor. The windows had chrome tables and the van had a more comprehensive dashboard than the normal T1.

The VW Type 2 became popular with the counterculture of the 1960s, thanks to its ability to transport a large group of people while being cheap and easy to maintain. Its design was simple yet spacious, thanks largely to the rear-mounted engine. It contrasted with the large sedans and station wagons that were normal at the time, giving the van an alternative and rebellious image. Vans were often painted with extravagant designs in bright colors, making them stand out on the road even more. The "hippie van" remains iconic today, thanks to being featured on the cover of albums by musicians such as Bob Dylan and the Beach Boys, and being used by fans of the Grateful Dead while following the band on tour. But most iconic of all, the music festival Woodstock, which was held in the summer of 1969, saw plenty of brightly-painted vans transporting excited young crowds.
