Not may people know it, but the M5 celebrates its 35th birthday this year. As part of the "celebration", I thought that you all might be interested in seeing the very first Motorsport E12 produced. This article came out in the August 1974 edition of Auto Zeitung in Germany, and shows the first car that BMW Motorsport built as a test bed for the E12s. This car has a 3.0 liter carbureted engine from the E3/E9's, as well as a rollover bar (which made the car usless), special BBS wheels, Bilstein suspension, and a 4 speed transmission. Even then they said that they were planning on building a small run of these cars with both 3.0 liter carbureted and injected engines. It seems that the author wasn't blown away by the power (only 180 hp) of the car, but he had nothing but praise for the suspension and the brakes. I guess this really shows how far BMW has come with this concept in the past 35 years.
