Following the path of the New Six concept launched in 1968 with the E3 bodywork, the first generation of the BMW 7-Series was unveiled in 1977. The first 7-Series started its climb on the ladder of success in 1977 with a lineup of vehicles that featured only six-cylinder engines. A prototype model featured a V12 engine, but it was just one of a kind. Its angled fascia resembled a shark nose profile. The vehicle's look was modern and it was a complete step away from the previous design trend. The only design idea that was carried over was the four rounded headlights concept. Other than that, everything was new. The flat, wide slightly upward hood was accompanied by a simple greenhouse and a descending trunk lid. The chromed bumpers were a fashion for the cars on those times. In 1983, when the facelift occurred, the kidney grille was enlarged and new plastic-covered bumpers appeared. Inside the vehicle, the 7-series featured numerous innovations such as the service-control lights, climate control, and the on-board computer. The base model with the basic trim featured cloth seats and manual gearbox, but more amenities were added for the upper trim levels including sunroof, power windows, leather seats, and power locks. The engine line-up started with engines with four-barrel Solex carburetors, but soon all the engines received Bosch fuel injection systems. The most powerful engine was the 286 hp 754i, a model that featured an inline-six unit, aided by a turbocharger.
