The Golf Mk2 was available as a 3- and 5-door hatchback. The 2-door and 4-door sedan variants of the Golf Mk2 were marketed under the Volkswagen Jetta name. No cabriolet version was developed from the Mk2; instead, the Mk1-based convertible continued to be produced, with minor changes.

Trim levels included base, C, CL and GL and initially a range-topping Carat model (until 1986), later a GT (in 1987) version was also on offer. In North America, there was only a base model until 1986, in 1987 a GL and GT model, in 1988–1989, there were all three, and in 1990 until the end of its run there was again only a GL. The GTI model existed from 1985 to 1987, and again from 1990 to 1992, and the GTI 16v existed from 1987 to 1992. In Japan the range consisted of catalysed Ci/CLi/GLi models all sharing the same 1.6 or later 1.8 liter fuel-injected inline-four engines. In the course of the years, a host of "limited edition" models appeared on various markets, distinguished by cosmetic changes and/or an enriched features list. Generally, these were option packages on top of a base "model" (CL, GL, etc.). Also in some countries it could be found trim level TX (Austria) and JX (Yugoslavia).

The base engine was initially the 1.3 option as used in the first generation Golf, accompanied by 1.6- and 1.8-litre petrol fours and 1.6-litre naturally aspirated or turbocharged diesel engines. In January 1984 a new base engine was introduced, a 1.05 litre inline-four mainly available in Italy and Greece. In North America, all Golf Mk2s had 1.8-liter petrol or 1.6 diesel engines (the GTI, while not a Golf model in North America, also had a 2.0-liter model).

The MK2 was the last version of the Golf to feature carburettor petrol engines, as all versions of the MK3 came with fuel injection from its launch, to meet requirements that all new cars sold in the EEC after 1992 must be fitted with a catalytic converter or fuel injection.

​

The successful Golf GTI (or, in the US, simply "GTI") was continued with the Mk2 as a sporty 3- or 5-door hatchback. Like late Mk1 GTIs, it featured a naturally aspirated Bosch K-Jetronic fuel injected 1781 cc inline-four engine developing 112 PS (82 kW; 110 hp). In 1986 (1987 for North America) a Golf GTI 16V was introduced; here the 1.8 litre engine output was 139 PS (137 hp; 102 kW) at 6,100 rpm (or 129 PS (95 kW) for the catalyst version) and 168 N⋅m (124 lb⋅ft) at 4,600 rpm of torque,[6] the model was marked by discreet red-and-black "16V" badges front and rear. North American-market GTIs were later equipped with 2.0-liter, 16-valve engines, only available in the Passat and Corrado outside North America. In 1990, like the Golf, the GTI was given a facelift, and the "Big Bumper" became standard on all GTIs. This was maintained through the rest of the Mk2 model era. In 1990 the GTi G60 was also introduced featuring the 8v 1.8 with a G60 supercharger this version is not to be confused with the very rare G60 Limited (see below).

For the South African market, Volkswagen SA added a 2.0 8v engine in January 1992, the same engine which would go on to be used in the Mk3 model launched later that year.
