1978 BMW 635 CSi

For the first time in 1976, the number 6 became the symbol of a unique combination of dynamism and stylish elegance. The BMW 6 Series, created by the French BMW Head Designer Paul Bracq was longer and wider and thus provided more space and comfort in the interior. The roof construction demonstrated an elegant lightness yet again, the front section running to a point highlighted outstanding sporting capabilities. Six-cylinder in-line engines of 3.0 litres and 3.2 litres developed 185 hp and 200 hp under the bonnets of the BMW 630CS and the BMW 633CSi.

Starting in 1978, a 3.5-litre engine powered the BMW 635CSi with an astounding 218 hp, delivered by an engine bred directly on the race track. The first-generation BMW 6 Series cars were made dazzlingly conspicuous not only by their excellent driving dynamics but also by their leading-edge technology, which ensured comfort and safety. During a production period of 13 years, 86,216 vehicles were sold, making it the longest running BMW model at that time.
