It's no secret that BMW has made ample changes to the core of the latest M5 high-performance executive sedan. But people are still wondering if these warrant an upgrade or not over the previous iteration.
The flagship BMW M5 super-sedan has been around for more than four decades on the market – the legend started with the 1984 E28 BMW M5 powered by an inline-six and rocking a five-speed manual transmission and RWD. The E34 iteration upgraded the engine with higher displacement and also the transmission with another gear, but otherwise kept the coordinates much the same.
The E39 generation made the first daring change – a 4.9-liter S62 V8 engine was tucked under the hood with up to 400 ps (395 horsepower).
