The Golf GTi was more an evolution than a revolution.
Its mechanics were that of the ordinary Golf, however
the power was to come from a more sporty Audi-designed
1.6 litre engine.
Other improvements over the standard Golf were to include
stiffer springs, bigger wheels and front disc brakes,
closer gear ratios and a lower ride height - all the ingredients
needed to make a hot hatch.
The 1.6 litre twin-carburettor engine developed 100 bhp,
which was soon upgraded with Bosch K-Jetronic fuel injection
increasing power to 110 bhp.
Combined with 5-speed transmission
, (replaced the 4-speeder
in 1981), it could do 0-100 km/h in around 9 seconds. In
1982, the engine was stroked-out to 1.8 litres, which
gave a slight power rise of 2 hp and 13 lbft.
