A history of//Initial research

The Volkswagen Type 2, known officially, depending on body type as the Transporter, Kombi and Microbus, and informally as the Bus (US) or Camper(UK), is a panel van introduced in 1950 by 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.

As one of the forerunners of the modern cargo and passenger vans, the Type 2 gave rise to forward control competitors in the United States in the 1960s, including the Ford Econoline, the Dodge A100, and the Chevrolet Corvair 95 Corvan, the latter adopting the Type 2's rear-engine configuration. European competition included the 1960s FF layout Renault Estafette and the FR layout Ford Transit. The FF layout Citroën H Van though, pre-dated the VW by three years. As of January 2010, updated versions of the Type 2 remain in production in international markets— as a passenger van, as a cargo van, and as a pickup truck.

Like the Beetle, the van has received numerous nicknames worldwide, including the "microbus", "minibus",and, due to its popularity during the counterculture movement of the 1960s, "Hippie van".

History

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 Holland, where he saw an improvised parts-mover and realized something better was possible using the stock Type 1 pan. He first sketched the van in a doodle dated April 23, 1947, proposing a payload of 690 kg (1,500 lb) and placing the driver at the very front. Production would have to wait, however, as the factory was at capacity producing the Type 1.

When capacity freed up a prototype known internally as the Type 29 was produced in a short three months. The stock Type 1 pan proved to be too weak so the prototype used a ladder chassis with unit body construction. Coincidentally the wheelbase was the same as the Type 1's. Engineers reused the reduction gear from the Type 81, enabling the 1.5 ton van to use a 25 hp (19 kW) flat four engine.

Although the aerodynamics of the first prototypes were poor (with an initial drag coefficient of 0.75), engineers used the wind tunnel at the Technical University of Braunschweig to optimize the design. Simple changes such as splitting the windshield and roofline into a "vee" helped the production Type 2 achieve a drag coefficient of 0.44, exceeding the Type 1's 0.48.Volkswagen's new chief executive officer Heinz Nordhoff (appointed 1 January 1948) approved the van for production on 19 May 1949 and the first production model, now designated Type 2, rolled off the assembly line to debut 12 November. Only two models were offered: the Kombi (with two side windows and middle and rear seats that were easily removable by one person), and the Commercial. The Microbus was added in May 1950, joined by the Deluxe Microbus in June 1951. In all 9,541 Type 2s were produced in their first year of production.

An ambulance model was added in December 1951 which repositioned the fuel tank in front of the transaxle, put the spare tire behind the front seat, and added a "tailgate"-style rear door. These features became standard on the Type 2 from 1955 to 1967. 11,805 Type 2s were built in the 1951 model year. These were joined by a single-cab pickup in August 1952, and it changed the least of the Type 2s until all were heavily modified in 1968.

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 T25) However only generations T1 to T3 (or T25 as it is still called in Ireland and Great Britain) can be seen as directly related to the Beetle (see below for details).

The Type 2, along with the 1947 Citroën H Van, are among the first 'forward control' vans in which the driver was placed above the front roadwheels. They started a trend in Europe, where the 1952 GM Bedford CA, 1959 Renault Estafette, 1960 BMC Morris J4, and 1960 Commer FC also used the concept. In the United States, the Corvair-based Chevrolet Corvan cargo van and Greenbrier passenger van went so far as to copy the Type 2's rear-engine layout, using the Corvair's horizontally opposed, air-cooled engine for power. Except for the Greenbrier and various 1950s–70s Fiat minivans, the Type 2 remained unique in being rear-engined. This was a disadvantage for the early "barndoor" Panel Vans, which could not easily be loaded from the rear due to the engine cover intruding on interior space, but generally advantageous in traction and interior noise.

Variants of the VW van:

The Type 2 was available as a:

• Panel van, a delivery van without side windows or rear seats.
• Nippen Tucket, available in six colours, with or without doors.
• Walk-Through Panel Van, a delivery van without side windows or rear seats and cargo doors on both sides.
• High Roof Panel Van (German: Hochdach), a delivery van with raised roof.
• Kombi, from German: Kombinationskraftwagen (combination motor vehicle), with side windows and removable rear seats, both a passenger and a cargo vehicle combined.
• Bus, also called a Volkswagen Caravelle, a van with more comfortable interior reminiscent of passenger cars since the third generation.
• Samba-Bus, a van with skylight windows and cloth sunroof, first generation only, also known as a Deluxe Microbus. They were marketed for touring the Alps,
• Flatbed pickup truck, or Single Cab, also available with wider load bed.
• Crew cab pick-up, a flatbed truck with extended cab and two rows of seats, also called a Doka, from German:Doppelkabine.
• Westfalia camping van, "Westy", with Westfalia roof and interior.
• Adventurewagen camping van, with high roof and camping units from Adventurewagen.
• Semi-camping van that can also still be used as a passenger car and transporter, sacrificing some camping comforts. "Multivan" or "Weekender", available from the third generation on.

Apart from these factory variants, there were a multitude of third-party conversions available, some of which were offered through Volkswagen dealers. They included, but were not limited to, refrigerated vans, hearses, ambulances, police vans, fire engines and ladder trucks, and camping van conversions by companies other than Westfalia. There were even 30 Klv 20 rail-going draisines built for Deutsche Bundesbahn in 1955.

T1

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.

The early versions of the T1 until 1955 were often called the "Barndoor" (retrospectively called T1a since the 1990s), owing to the enormous rear engine cover, while the later versions with a slightly modified body (the roofline above the windshield is extended), smaller engine bay, and 15" roadwheels instead of the original 16" ones are nowadays called the T1b (again, only called this since the 1990s, based on VW's restrospective T1,2,3,4 etc. naming system.). From the 1964 model year, when the rear door was made wider (same as on the bay-window or T2), the vehicle could be referred to as the T1c. 1964 also saw the introduction of an optional sliding door for the passenger/cargo area instead of the outwardly hinged doors typical of cargo vans.

In 1962, a heavy-duty Transporter was introduced as a factory option. It featured a cargo capacity of 1,000 kg (2,205 lb) instead of the previous 750 kg (1,653 lb), smaller but wider 14" roadwheels, and a 1.5 Le, 31 kW (42 PS; 42 bhp) DIN engine. This was so successful that only a year later, the 750 kg, 1.2 L Transporter was discontinued. The 1963 model year introduced the 1500 engine – 1,493 cc (91.1 cu in) as standard equipment to the US market at 38 kW (52 PS; 51 bhp) DIN with an 83 mm (3.27 in) bore, 69 mm (2.72 in) stroke, and 7.8:1 compression ratio. When the Beetle received the 1.5 L engine for the 1967 model year, its power was increased to 40 kW (54 PS; 54 bhp) DIN.

German production stopped after the 1967 model year; however, the T1 still was made in Brazil until 1975, when it was modified with a 1968–79 T2-style front end, and big 1972-vintage taillights into the so-called "T1.5" and produced until 1996. The Brazilian T1s were not identical to the last German models (the T1.5 was locally produced in Brazil using the 1950s and 1960s-era stamping dies to cut down on retooling, alongside the Beetle/Fusca, where the pre-1965 body style was retained), though they sported some characteristic features of the T1a, such as the cargo doors and five-stud 205 mm (8.1 in) PCD rims.

Among American enthusiasts, it is common to refer to the different models by the number of their windows. The basic Kombi or Bus is the 11-window (a.k.a. three window bus because of three side windows) with a split windshield, two front cabin door windows, six rear side windows, and one rear window. The DeLuxe model featured eight rear side windows and two rear corner windows, making it the 15-window (not available in Europe). Meanwhile, the sunroof DeLuxe with its additional eight small skylight windows is, accordingly, the 23-window. From the 1964 model year, with its wider rear door, the rear corner windows were discontinued, making the latter two the 13-window and 21-window respectively. The 23- and later 21-window variants each carry the nickname 'Samba', or in Australia, officially 'Alpine'.


T2

In late 1967, the second generation of the Volkswagen Type 2 (T2) was introduced. It was built in Germany until 1979. In Mexico, the Volkswagen Combi and Panel were produced from 1970 to 1994. Models before 1971 are often called the T2a (or "Early Bay"), while models after 1972 are called the T2b (or "Late Bay").

This second-generation Type 2 lost its distinctive split front windshield, and was slightly larger and considerably heavier than its predecessor. Its common nicknames are Breadloaf and Bay-window, or Loaf and Bay for short. At 1.6 L and 35 kW (48 PS; 47 bhp) DIN, the engine was also slightly larger. The new model also did away with the swing axle rear suspension and transfer boxes previously used to raise ride height. Instead, half-shaft axles fitted with constant velocity joints raised ride height without the wild changes in camber of the Beetle-based swing axle suspension. The updated Bus transaxle is usually sought after by off-road racers using air-cooled Volkswagen components.

The T2b was introduced by way of gradual change over three years. The first models featured rounded bumpers incorporating a step for use when the door was open (replaced by indented bumpers without steps on later models), front doors that opened to 90° from the body, no lip on the front guards, and crescent air intakes in the D-pillars(later models after the Type 4 engine option was offered, have squared off intakes). They also had unique engine hatches, and up until 1971 front indicators set low on the nose rather than high on either side of the fresh air grille – giving rise to their nickname as "Low Lights". The 1971 Type 2 featured a new, 1.6 L engine with dual intake ports on each cylinder head and was DIN-rated at 37 kW (50 PS; 50 bhp). An important change came with the introduction of front disc brakes and new roadwheels with brake ventilation holes and flatter hubcaps. 1972's most prominent change was a bigger engine compartment to fit the larger 1.7- to 2.0-litre engines from the Volkswagen Type 4, and a redesigned rear end which eliminated the removable rear apron. The air inlets were also enlarged to accommodate the increased cooling air needs of the larger engines.

In 1971 the 1600cc Type 1 engine as used in the Beetle, was supplemented with the 1700cc Type 4 engine – as it was originally designed for the Type 4 (411 and 412) models. European vans kept the option of upright fan Type 1 1600 engine but the 1700 Type 4 became standard for US spec models.

In the Type 2, the Type 4 engine was an option for the 1972 model year onward. This engine was standard in models destined for the US and Canada. Only with the Type 4 engine did an automatic transmission become available for the first time in the 1973 model year. Both engines displaced 1.7 L, DIN-rated at 49 kW (67 PS; 66 bhp) with the manual transmission and 46 kW (63 PS; 62 bhp) with the automatic. The Type 4 engine was enlarged to 1.8 L and 50 kW (68 PS; 67 bhp) DIN for the 1974 model year and again to 2.0 L and 52 kW (71 PS; 70 bhp) DIN for the 1976 model year. The 1978 2.0 L now featured hydraulic valve lifters, eliminating the need to periodically adjust the valve clearances as on earlier models. The 1975 and later U.S. model years received Bosch L-Jetronic electronic fuel injection as standard equipment; 1978 was the first year for electronic ignition, utilizing a hall effect sensor and digital controller, eliminating maintenance-requiring contact-breaker points. As with all Transporter engines, the focus in development was not on power, but on low-end torque. The Type 4 engines were considerably more robust and durable than the Type 1 engines, particularly in Transporter service.

The year 1971 also saw exterior revisions including relocated front turn indicators, squared off and set higher in the valance, above the headlights – 1972 saw square-profiled bumpers, which became standard until the end of the T2 in 1979. Crash safety improved with this change due to a compressible structure behind the front bumper. This meant that the T2b was capable of meeting US safety standards for passenger cars of the time, though not required of vans. The "VW" emblem on the front valance became slightly smaller.

Later model changes were primarily mechanical. By 1974, the T2 had gained its final shape. Very late in the T2's design life, during the late 1970s, the first prototypes of Type 2 vans with four-wheel drive(4WD) were built and tested.

T3

The Volkswagen Type 2 (T3) also known as the T25, (or Vanagon in the United States), the T3 platform was introduced in 1980, and was one of the last new Volkswagen platforms to use an air-cooled engine. The Volkswagen air-cooled engine was phased out for a water-cooled boxer engine (still rear-mounted) in 1984. Compared to its predecessor the T2, the T3 was larger and heavier, with square corners replacing the rounded edges of the older models.


T4
Since 1990, the Transporter in most world markets has been front-engined and water-cooled, similar to other contemporary Volkswagens, almost two decades later than it did for the passenger cars. T4s are marketed as Transporter in Europe, the UK and Ireland. In the United States, Volkswagen Eurovan is the brand name. The T4 is the first Volkswagen van to officially use the 'Transporter' title.


T5

The Volkswagen Transporter T5 range is the fifth generation of Volkswagen Commercial Vehicles medium-sized light commercial vehicle and people movers. Launched 6 January 2003, the T5 went into full production in April 2003, replacing the fourth generation range.

Key markets for the T5 are Germany, the United Kingdom, Russia, France and Turkey. It is not sold in the US market due to it being classed as a light truck, accuring the 25% chicken tax on importation. The T5 has a more aerodynamic design. The angle of the windshield and A-pillar is less; this makes for a large dashboard and small bonnet.

In June 2009, Volkswagen Commercial Vehicles announced the one-millionth T5 rolled off the production line in Hannover.
