BMW M5 E39 -Overview

Overview

BMW M5 E39 — Overview

The BMW M5 E39 is the third generation of BMW's iconic super saloon, produced from October 1998 to June 2003. It marked a significant departure from its predecessors — for the first time, the M5 was powered by a V8 engine rather than a straight‑six. The S62B50 4.9‑litre V8, developed by M Division, produced 400 PS and 500 Nm of torque, propelling the 1,795 kg saloon from 0‑60 mph in 5.3 seconds (with contemporary tests achieving 4.8 seconds).

The engine featured double VANOS variable valve timing, individual throttle bodies, and a six‑speed manual gearbox. The E39 M5 is widely regarded as one of the greatest sports sedans ever made.

Best & Worst Engines

The Only Engine

S62B50 4.9-litre V8

“The E39 M5's S62B50 V8 is the only engine available — and it's a masterpiece. 400 PS, 500 Nm, individual throttle bodies, and a 7,000 rpm redline make it one of the greatest naturally aspirated V8s ever fitted to a saloon. It is a robust engine when properly maintained, but age has brought a litany of common issues: rod bearing wear is the most serious, with failure leading to catastrophic engine damage. VANOS seal degradation causes poor low-end performance and rattle. Timing chain guides, made of plastic, become brittle and can fail. The cooling system is a known weak point — radiators, water pumps, and thermostats all require proactive replacement. Throttle body actuators can fail, triggering limp mode.”

Who it's for: enthusiasts who value one of the greatest driving experiences ever created — and who have the budget to maintain it properly.

The E39 M5 rule

A £3,000–£6,000 S62 recon against a £15,000–£40,000 E39 M5 sits at 7.5–40% of the car's value -well within our 70% BMW threshold. These are appreciating classics -engine replacement is a preservation cost, not a decision point. However, annual maintenance costs of £2,000–£3,000 are the real ownership burden. Budget accordingly, and you'll be rewarded with one of the greatest driving experiences ever created.

Scope note: All variants listed are E39 M5 Saloon only. No M5 Touring was produced for the E39 generation. The E39 M5 was produced in three main specifications: European left‑hand drive, European right‑hand drive (UK market), and North American specification. Changes were limited to emissions equipment, lighting, and minor trim differences. A facelift was introduced in September 2000, bringing corona‑ring headlights, revised rear lights, grey‑faced instruments, and Alcantara headlining. Engine specifications remained unchanged across all variants and model years.
