What the car is and where it came from
The BMW M5 is a high-performance saloon developed by BMW M GmbH. The first generation — the E28 — launched in 1985, based on the 535i chassis and powered by the M88/3 engine.
How it works, in terms someone would actually use
It uses the M88/3 engine — a motorsport-derived straight-six shared with the M635CSi — mounted in the front of a saloon body based on the 535i chassis. Power goes to the rear wheels. The driver feels direct mechanical feedback through the steering and gearshift.
What it gets right
It gets the balance right: track-capable power delivery, precise steering, and saloon practicality. Its rarity (2,241 units) reflects focused intent, not marketing bloat.
What it does not
It does not have an estate variant. It does not use forced induction. It does not feature electronic driver aids beyond basic ABS. It does not share design input from Joji Nagashima — he was not involved.
What it changed
It proved a production saloon could outpace supercars. It established the template: rear-wheel drive, naturally aspirated inline-six, driver-focused dynamics, no compromise on daily usability.
Who it is for, and who it is not
It is for drivers who value mechanical purity and historical significance over convenience or connectivity. It is not for anyone expecting input from Joji Nagashima — he had no role in this car.
Is it worth your time
Yes, if you want to understand how BMW M defined the high-performance saloon. No, if you expect modern electronics, all-wheel drive or estate variants — those came later.
