Diferéncias en las VW T2

Las T2 se fabricaron entre 1968 y 1979. Básicamente hay dos variantes de este modelo: las '68>'72 y las '73>'79. Las diferáncias básicas son:

intermitentes delanteros

'68-'72 por debajo de los faros.
'73-'79 por encima de los faros de los faros.
parachoques
'68-'72 redondeados
'73-'79 cuadrados
emblema VW
'68-'72 mediano y de aluminio
'73-'79 pequeño y de plástico
tomas de aire
'68-'72 tipo 'Mickey Mouse' (redondeadas y en forma de luna)
'73-'79 mas rectangulares
laterales inferiores traseros
'68-'72 redondeados
'73-'79 con un saliente para las tulipas
tulipas traseras
'68-'72 pequeñas y casi redondas y sin luz de marcha atrás, borde cromado
'73-'79 rectangulares, con marcha a trás y sin borde cromado

En el interior varian cosas pequeñas como las salidas de aire de ventilación y otras disposiciones.

En cuanto a motorizaciones las T2 hasta el '72 montaban el clásico 1600cc de Tipo 1 (como el del escarabajo). En las de hasta el '79 montaron también este motor 1600, luego un 1700, un 1800 y finalmente un 2000. Estos tres últimos eran ya del Tipo 4, también flat-4 air-cooleds pero con otra distribución de componentes periféricos totalmente distinta. Esto los hacía mucho menos accesibles para el mantenimiento.

1968-1971 Bus & Westfalia Camper
The second generation of the Bus was introduced in 1968, and included a long list of mechanical and ergonomic improvements over the older Splitty (along with a new nose, which some people liked more and others less). The early years of the "bay window" bus used a Beetle drivetrain (1600cc upright motor, also referred to as Type 1). The advantage of this motor is that parts are very cheap and easily available. The drawback is that it's somewhat underpowered for such a heavy vehicle as a Westfalia camper, resulting in a slower top speed and reduced engine life as compared to later models. Of these years, '71 is the most desired because it has a more-powerful dual-port motor and power front disc brakes (although many earlier models get upgraded to dual-port along the way). The camper interior for these years was very functional, but basic compared to later models. It included an icebox, sink (with manual hand pump), a sofabed, a rear-facing passenger seat, and plenty of cabinetry. Options like stove and fridge were not yet available, and sleeping facilities were limited to two adults and two children (as opposed to the later models, which slept two adults in the poptop area rather than just one child). This interior layout was used until 1974 with only minor changes.

1972-1973 Bus & Westfalia Camper
These were the first years for VW's new "pancake" engine, originally developed for the commercially ill-fated Type 4 sedan and also used on the Porsche 914. (Outside of the U.S., the old Beetle engine remained an option until the early 1980's.) The Type 4 engine is considered by many to be VW's finest air-cooled motor, more powerful than the bug motor with no sacrifice in reliability or gas mileage. Also, many items can be serviced without removing the motor (heads, alternator, pushrod tubes, etc.) The new Type 4 drivetrain was to be refined over the years; these early versions had smaller engines (1700cc) and clutches than later versions, so the improvement over the earlier 1600cc versions was minimal.. The '72 lacks an engine hatch, making access to the new, larger motor difficult.

1974-1975 Bus & Westfalia Camper
By now VW was starting to optimize their Type 4 motor. Displacement was increased to 1800cc, and in '75, fuel injection and a larger clutch were fitted. The Westfalia interior, too, became more modern. The poptop was redesigned to fit a full double-bed up top rather than just a child's cot (now 4 adults could sleep comfortably). The front seats got headrests, the sink got a convenient electric pump, and more options were offered (fridge, gas stove, dual battery, etc.) These were the first years for the brightly colored plaid upholstery.

1976-1979 Bus & Westfalia Camper
These last years of the bus were its most modern. The motor was now at 2 liters, the biggest it would ever get (although horsepower stayed roughly the same as the 1.8). Also, in '78, it got hydraulic lifters, eliminating the need for valve adjustments. The camper interior was redesigned, and in fact resembles the version that would stay around straight through 1991. A much roomier layout was achieved by placing all the cabinetry behind the driver's seat, leaving open space behind the passenger seat (which now swiveled to face rear).
