It worked: The modern and reliable drive concept, the excellent spatial economy and ultimately the design as well, won over the market to such an extent that production of the one-millionth Golf was already being celebrated in October 1976. Like every Golf that would appear after it, the first generation, too, reflected the progress and automotive trends. In launching the first Golf GTI (in 1976), Volkswagen heralded the introduction of greater dynamism in this class, while the Golf D (naturally aspirated diesel engine, 1976) and the later Golf GTD (turbodiesel, 1982) marked the breakthrough for diesel cars in the compact segment. With the Golf Cabriolet, introduced in 1979, Volkswagen launched an open car on the market that was at times the best-selling open car in the world. 6.99 million vehicles of the first generation Golf, including all derivatives such as the convertible and the Jetta (at that time structurally identical), were sold – 0.87 million Golf cars per year. Golf II. It was the second generation Golf that was the Volkswagen in which the baby-boomer generation, people who are now in their fifties and sixties, learned to drive. While its predecessor had already become a favourite of all driving instructors and learner drivers, the second Golf had now become firmly and inerasably established in the minds of these temporary allies. As of August 1983, they no longer sat quite so close to each other, since spatial utilisation had been improved once more. As a matter of fact: it was the Golf that introduced the regulated catalytic converter (1984), anti-lock braking system (ABS, 1986) and power-steering to the Golf class and that could be ordered with an all-wheel drive system for the first time (Syncro, 1986). And as far back as 1989, Volkswagen was already unveiling a prototype of this Golf with an electric drive system and another with a hybrid drive system.
