of 5 million Mk1 VW LTs built, only 1,250 featured four-wheel drive. Typ codes The Volkswagen "Typ codes" for the first generation LT were: Typ 28 — April 1975 to July 1991 ''Typ 21 — August 1991 to December 1995 Typ 29 — 4x4 1984 to 1989 The last first-generation LT was produced in 1996, which corresponds to a British 'P' registration plate. In 21 years, just under 500,000 vehicles were assembled. Engines The petrol engine was a modified Audi 100 VW EA831 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 did not 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 build it anyway in a collaboration with VW culminating in the Porsche 924 running with an VW EA831 Audi 2 L engine with Bosch K-Jetronic injection which is the same basic engine that was in the 2 L petrol LT at the time albeit with a carburetor and a vastly uprated Porsche designed cylinder head. 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 L 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 . 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 and of torque. In addition, the six-cylinder engine was now also available as a 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 was introduced – the Volkswagen D24TIC engine. Early DV/ACL engine valves are mechanically shimmed; later versions were hydraulically auto-adjusted. The ACL had bigger injectors
