11. BMW 745i E23
In 1983, BMW South Africa introduced a special car they called the 745i. It was powered by a naturally aspirated M88 engine from the famous M1 supercar. The six-cylinder with 286 HP was one of the hottest engines from BMW. In the biggest, most luxurious sedan in the lineup, it was quite an unusual combination, even by today’s standards. But the 745i turned out to be a fast and capable car.
It was fast enough to go racing too. In an extremely interesting turn of events, the big 745i won the South African touring car championship. It became the first 7 Series sedan to win a major race series. Most people think BMW never produced the M7 model, but apparently, it did. It was just not under that name and in just 209 examples.
