History

Volkswagen introduced the Volkswagen Type 2 in 1950 and developed light commercial vehicle versions for German and European markets. The name "Kombi" (the name under which the Type 2 was sold in Brazil) established itself as a concept term to describe an entire light commercial vehicle segment. The automaker introduced the revised Volkswagen Type 2 (T2) in 1968. Commercial customers were shipping heavier and larger-volume freight. The Volkswagen Type 2 platform was also limited by its rear-mounted engine design.

Design

The new design specifications for a larger transporter as an additional series ranged from 2.8 tons gross vehicle weight to 3.5 tons. The layout was a conventional rear drive with the engine located above the front axle, in a forward control or 'cab over' design.

The new Volkswagen van was launched in 1975 in Berlin. The name given to Volkswagen's large transporter was as functional as the entire vehicle: it was just called LT, which is simply the abbreviation of Lasten-Transporter (or cargo transporter).

The LT came in three gross vehicle weights, from 2.8 to 3.5 tons (LT 28, LT 31, LT 35), with two wheelbases, two roof options, and with bodywork options as a panel van, a compact, a platform vehicle and a chassis cab combination.

The design featured a high ratio of utility space to footprint due to its forward control design and overall width of 2.085 metres (6 ft 10.1 in). The compact LT panel van (with a little over four and a half metres in length) offered an interior load length of over three metres and a load area of around 5.5 square metres.

Suspension/Axles

The LT was equipped with a front axle with independent front wheel suspension. Later options, such as the heavy LT 40 to LT 55, had a solid front axle to achieve increased to load-carrying capacity as is common for light trucks.

Facelifts

The first facelift in 1983 changed mostly the interior, at the same time as the engine cover was changed and the turbo-diesel and inline-6 petrol engines were introduced. A redesigned dashboard was added and various other small things were changed. The undercarriage had an additional third wheelbase as an option for platform-type vehicles, at up to 4.6 metres in length.

Volkswagen LT 28 converted to a campervan

Two years later, Volkswagen again increased the gross vehicle weight, with the 5.6 ton LT 55. It was available with a single-tyre rear axle, allowing for more space between rear wheel wells inside the cargo floor. An LT with four-wheel drive that could be enabled from within the cab was also available.

The next facelift in 1986 changed the round headlights to rectangular units, as well as other minor cosmetic retouches.

In Spring 1993, there was again a modest change in the look, with new grey-plastic elements introduced to the radiator grille and in the rear lighting section. The diesel engines were replaced with a more modern version of the same block. The DW (N/A diesel) was replaced by the ACT engine and the DV (turbo-diesel) engines was replaced by the intercooled ACL engine. Additionally to that, the engine cover was replaced with a new version, that had an opening in the front allowing to check the coolant without having to open the entire engine cover.

Campervan versions

A touring camper in its various bodywork and fitting options was also produced. The vehicle's width allowed the possibility of beds arranged crosswise. Various Volkswagen-endorsed Westfalia campervan models were available for the LT, including the Sven Hedin, and a later model, Florida. The LT was also used by Karmann who produced over 3,000 Karmann LT Distance Wide coachbuilt motorhomes.

Truck cabs

The "G Series" light truck was a joint venture between Volkswagen and MAN AG, with gross vehicle weights of between six and ten tons. It was built from 1979 until 1993.

Volkswagen's Brazilian plant at Resende has been constructing trucks with weights of between 7 to 35 tons. Even after the launch of the new Volkswagen Constellation in 2006, Volkswagen Commercial Vehicles has continued to manufacture vehicles incorporating cabs based on the first generation of the LT. The Volkswagen Titan has succeeded in winning the European Cup in the Super Truck Race. Its cab is similarly based on the first generation of the LT's cab.

Rebadging

In the late eighties, German-built Volkswagen LT and MAN-VW G were sold in Spain as Pegaso Ekus, while Brazilian-built units were marketed in USA as Peterbilt Midrangers.

4x4

The LT also existed in 4x4. VW already prepared for this in 1983 with the facelift of the cab, as the instrumentation has lights for front, center and rear differential locks.

Sülzer developed a 4x4 version of the VW LT based on the long wheel base. These were either LT40 or LT45. Opposed to the normal LT40 & LT45, the 4x4's only had single wheels on the rear axle. The chassis was lifted and a propshaft driven, rod/shaft controlled transferbox was installed under the vehicle. The front and rear axles were replaced.

The transferbox was a New Process 208. The first 6 of the Sülzer vehicles are supposed to have had Dana axles. After that production was changed to use the Italian build Clark-Hurth axles. Differential-Lock on the rear axle came as factory default. The front diff-lock came optional.

Due to the change of axles, the 4x4 LT's came with completely different rims to the normal LT's. All 4x4 LT's have 6 stud tube type split-rims in 6.5J width. The standard tyre fitment on these rims is 7.00x16 or 7.50x16. The biggest tyre, that these rims will take is 9.00x16 (or 255/100/16), which will give another 6 cm of ground clearance, but that will require arch modifications in the front.

Mefro has a 16x8J ET0 rim in their portfolio, that will fit the 4x4 LT, but these can't be bought directly. Owners have managed to get hold of these rims over a group buy.[2] The Mefro rims will then allow to run 285/75/16 tyres on the 4x4 LT.

Another wheel option has been truck rims and tyres, using 17.5" rims from trucks, which have the same PCD as the 4x4 LT's. It's however near to impossible to find offroad tyres in 17.5".

In 1985 VW took over the production of the 4x4 LT's and introduced the DW (2.4 inline-6 N/A diesel) and DV (2.4 inline-6 turbo-diesel) engines to the portfolio. The model portfolio covered only long wheel base vehicles. Tintop and hightop as LT40, pickup and double-cab as LT40 or LT45.[1]

In 1991 the naturally aspirated diesel engine was dropped from the 4x4 program. So was the tintop variant. Front differential lock now became factory standard also and the transfer box was upgraded to the New Process 241.[3]

Steyr-Puch in Austria build the Noriker on VW LT basis in competition with the Sülzer and VW LT 4x4's, but they only were produced in very limited numbers.

De Vries also build 3 VW LT 4x4's on the same principle as Sülzer/VW, one of which was used in the Dakar Rally in 1983.[4]

Typ codes

The Volkswagen "Typ codes" for the first generation LT were:

The last first generation LT was produced in 1996, which corresponds to a British 'P' registration plate. In 21 years, just under 5,000,000 vehicles were assembled.

Engines

Volkswagen LT DV engine


The petrol engine was a modified Audi 100 2.0 L inline four-cylinder. In 1976 Volkswagen wanted to make a sports coupe and had Porsche design one for them using parts from the VW/Audi group bin with front engine and rear wheel drive. They didn't go with the design as the rest of the range was switching to front wheel drive i.e. Golf/Polo/Jetta so VW came up with another design (the Scirocco). Porsche then decided to built it anyway in a collaboration with VW culminating in the Porsche 924 running with an Audi 2Ltr engine with Bosch K-Jetronic injection which is the same basic engine that was in the 2Ltr petrol LT at the time albeit with a carburettor instead. It was rated at 55 kilowatts (75 PS; 74 bhp) and achieved higher torque at lower engine RPMs.

An inline four-cylinder diesel engine by Perkins was available. The 48 kilowatts (65 PS; 64 bhp) 2.7-litre diesel was included in the LT range from 1976 onwards.

The Perkins engine was replaced in 1978 with a six-cylinder variant of the Volkswagen Golf diesel. The original 1.6 L four-cylinder engine became the D24 2.4 L six-cylinder, delivering 55 kW (75 PS; 74 bhp). This engine was also used in a number of Volvo passenger cars.

In December 1982, an upgrade to the LT was introduced. The six-cylinder diesel was available as a turbodiesel, the Volkswagen D24T engine, producing 75 kilowatts (102 PS; 101 bhp) and 195 newton metres (144 lbf·ft) of torque. In addition, the six-cylinder engine was now also available as a 66 kilowatts (90 PS; 89 bhp) petrol engine. All engines were now mounted with a clear offset alignment that allowed for a flatter engine compartment, which was shifted further to the rear for more space for a third seat in the cab.

In 1992, an overhauled turbo-diesel engine with charge air cooler and 70 kilowatts (95 PS; 94 bhp) was introduced - the Volkswagen D24TIC engine.

History

In 1996, the joint venture of Volkswagen and Daimler's Mercedes-Benz Commercial introduced the second generation LT. The Volkswagen version shared the body shell with the new Mercedes-Benz Sprinter, however the engine and transmission were Volkswagen Group sourced. This deal would continue in the Volkswagen Crafter, successor to the LT.

The new design incorporated an engine mounted longitudinally beneath a short hood and with rear-wheel drive. The LT adopted what had become the standard style of construction for bigger transporters. It also included economical direct-injection diesel engines, easy access to the driver cab behind the front axle, and a wide space between the driver and passenger seat.

The range now went from 2.6 to 4.6 tons gross vehicle weight, and the enclosed options of the panel van and compact were available in three wheelbase options. Platform vehicles, crewcabs and numerous undercarriage options completed the range. A special articulated version of the second generation LT, the XLT was available through special order.

The Volkswagen "Typ codes" for the second generation LT are:

Engines

Engines included a naturally aspirated engine, as well as three Turbocharged Direct Injection (TDI) diesel engines. These were the inline-five-cylinder TDI used in the Volkswagen Eurovan (Type 2 T4). The performance range for the LT initially went from 61 kilowatts (83 PS; 82 bhp) to 96 kilowatts (131 PS; 129 bhp). In January 2002, an inline-four-cylinder 2.8 litre engine increased power output to 116 kilowatts (158 PS; 156 bhp), and the maximum torque to 331 newton metres (244 lbf·ft).
