In 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 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, electronic stability control, and a system that automatically increased spring pressure on the windshield wipers, to keep them firmly pressed on the glass at Autobahn speeds. Incidentally, the E32 was the first car adhering to BMW's self-imposed speed limit of 250 km/h (155.37 mph). According to the official American brochure in 1987, the ungoverned 750iL could reach 300 km/h (186.4 mph), with a side note that the terminal speed was electronically restricted. The car was also available in a stretched version (indicated by an 'L' after the model number), in which case an extra 11.4 centimetres (4.5 in) of leg room was available to the rear passengers by stretching the rear doors, and the body at this point. It was in all years 88-94 in the U.S.
