July 1986, BMW introduced the second generation of the 7 series, known internally as the E32. Aimed at the high end of the luxury market, the car offered some of the latest innovations in automotive technology, and (beginning in 1987) a new, top-of-the-line V12 engine. Some luxury options featured on the E32 included integrated telephone and fax machines, a wine cooler, double glazing, traction control system, and a system that automatically increased spring pressure on the windscreen wipers, to keep them firmly pressed on the glass at Motorway speeds. Design work began in late 1979, in which by 1983 1:1 scale models were presented and frozen in 1984 for 1986 production. The BMW 750iL Highline was the top-of-the-line model of the E32, with lots of added luxury for the rear passengers like full leather, dual radio controls, dual climate control with coolbox mounted in the center console, electrically heated and adjustable rear seats, walnut veneer folding tables, two crystal glasses neatly placed in the coolbox, legrests, and sun shade all around the rear/side windows. Complete with independent heating and ventilation, it also added a second battery in the trunk and a second alternator to provide power for all these luxuries. The ‘Highline’ option package cost more than 20,000 DEM, and was only available on the 750iL, bringing the total price to well over twice that of a ‘basic’ 730i. The 767iL Goldfish was a single prototype of E32 car powered with V16 engine. It was conceived in 1987 and built by the end of 1988. Because of the length of the engine cooling system (radiator) was moved to the trunk and additional vents were added at the rear. German tuning company Alpina was manufacturing 3 main models based on the E32 series cars. Those were B11 3.5 (3 engine versions), B11 4.0 and B12 5.0. In addition to tuned engines and suspension they were distinguishable by bodykit, pinstriping and trademark Alpina wheels. The BMW ‘kidney’ grille indicated which engine was present under the hood: all 6-cylinder models had a narrow grille, and all 8- and 12-cylinder models had the wider version. This feature was not seen on later models (the E38 used a wide grille for all models). The narrow grille was available as an option on the 8- and 12-cylinder E32 models. The E34 5 series, introduced in 1988, has design cues similar to the E32, and some engines and other parts are shared between the two cars.
