1. BMW M5 E28

The ’80s brought a slight rise in power and liberty to experiment even further. So, in 1984, BMW created history with the introduction of the first M5 model. They named it the E28 and it was the ultimate version of the popular 5-Series sedan. Under the hood was a highly-tuned 3.5-liter straight six engine with 265 to 288 HP, depending on the market.

Although this not sound much today, for the mid-80s, it was unbelievable power. And better yet, they paired it with the M-Performance tuned suspension and brakes. And that turned this family sedan into a proper sports car.
