We compare the first-gen and latest BMW M5 models.

We take a closer look at some of the key differences between the very first BMW M5 and the most recent hybrid version, in our ongoing series called Then and Now.

BMW redefined the world of high-performance sedans when it introduced the M5 in the mid-1980s. From the very first iteration (E28) the M5 badge has evolved into a tech-laden super saloon in the shape of the latest (G90) generation. Both embody BMW’s Ultimate Driving Machine ethos but differ vastly in power, size, and sophistication. We take a closer look at both.

Origins

The first BMW M5 was a revelation. Until that point German automakers simply made luxurious sedans that were built for long-distance cruising. The only performance versions were made by aftermarket firms, such as Alpina and AMG. Then everything changed.

BMW slotted a 3,5-litre inline-six (M88/3) taken from the company’s M1 supercar into the engine bay of an E28 5-Series. The M5 received specific parts from BMW Motorsport gaining a stiffer suspension. All power went to the rear wheels via a five-speed manual gearbox and a limited-slip differential. The, then, world’s fastest production sedan, was hand-built with subtle exterior cues like discreet spoilers and slightly wider wheels hiding its wolf-like nature. Its boxy 5 Series shape prioritised function over flair, with a utilitarian interior focused on driver engagement.

The E28 M5 shares a unique link with South Africa in that just about 150 units of were built at the company’s local plant. CKD kit of the high-performance saloon were brought in and assembled in BMW’s Rosslyn outside Pretoria. The local cars were highly specced with M-Technic body kits (not standard around the world) and full leather interiors.

Fast forward into the new millennium and so much has changed. The G90 M5, is a far cry from the progenitor of its bloodline. Launched in 2024, it features a 4,4-litre twin-turbocharged V8 with massive hybrid assist. An engine that is not used in any motorsport application. The newest M5 adopts a far more aggressive demeanour with flared arches, matrix LED lights, and a polarising oversized grille, blending luxury cues with carbon fibre accents for a more ostentatious presence. Like most versions that carried the famed M badge, the latest M5 is imported directly from Germany.

Tech

The E28 offered basic ABS, power steering, and optional air conditioning in a spartan cabin with analogue gauges and Recaro seats. It prioritised mechanical purity over gadgets. In stark contrast, the G90 brims with technology, including a hybrid system, a 14,9-inch curved display running iDrive, massaging seats and so much more.

In addition, the latest M5s offers the option of (limited) electric-only driving from its 18,6 kWh battery. Oh, and there is the (not-so small) matter of the mass difference. The latest M5 is the same mass of the original PLUS a Mazda MX-5… Despite that large-SUV-like weight the first hybrid M5 can still reel off some impressive performance stats.

With that in mind, check out the main differences between the car credited with creating the super saloon genre and its youngest offspring. We have chosen a few key areas. If you can think of other facets you’d like to see, as well as cars you’d like featured, let us know on our Facebook page.
