The BMW M5 represents the pinnacle of performance sedan engineering, a machine that transforms a luxury four-door into a high-revving, track-capable weapon. The old model designation, often referring to the E39 generation produced from 1998 to 2003, embodies a specific era of automotive engineering where naturally aspirated engines ruled the roost. This specific iteration of the M5 is celebrated for its raw, unfiltered power delivery and the visceral experience of driving a car that feels both civilized and ferocious.
The Heart of the Beast: The S62 V8 Engine
At the core of the old model M5 lies the legendary S62 4.9-liter V8 engine, a masterpiece of BMW engineering. Unlike its standard 5-Series siblings, this powerplant was built by hand at the M division in Garching, Germany. Producing 394 horsepower and 391 lb-ft of torque, the S62 utilized dual Vanos variable valve timing and a redline that screamed past 7,900 RPM. The sound, a metallic shriek that crescendos as the tachometer climbs, remains one of the most iconic auditory signatures in automotive history.
Engineering and Weight Distribution
Masters of dynamics, BMW engineers focused heavily on the chassis and weight distribution to handle the immense power. The E39 M5 employed a sophisticated multi-link rear suspension and an adaptive M electronic damper control system. This setup allowed the car to maintain composure at high speeds while remaining surprisingly agile through tight corners. The near 50/50 weight distribution ensured that the massive sedan felt planted and stable, inspiring confidence in even the most spirited driving sessions.
Exterior and Interior Design Language
Visually, the old model M5 commands attention with its muscular stance and aggressive front end. The flared wheel arches, larger front air dam, and distinctive quad exhaust tips signal its performance intent. Inside, the cabin is a sanctuary of driver-focused ergonomics, featuring bucket seats with bolstered support, a flat-bottomed M steering wheel, and an array of chrome accents. The combination of high-quality leather, brushed aluminum, and the sheer presence of the V8 engine creates an atmosphere of refined aggression that is difficult to replicate in modern, tech-heavy interiors.
Performance Metrics and Real-World Driving
While numbers on a spec sheet can only tell part of the story, the old model M5’s performance is undeniable. It sprinted from 0 to 60 mph in just over 5 seconds and carved through the quarter-mile in the high 13-second range. On the road, the experience was a blend of comfort and intensity; the car was quiet and smooth on the highway, yet transformed into a snarling predator the moment the throttle was pressed deeper. The manual transmission, a rarity in its class, placed the driver directly in control of every gear change, forging a mechanical connection that modern paddle shifters often lack.
The Legacy and Collector Appeal
Time has been kind to the old model BMW M5. Once overlooked in favor of newer, more technologically advanced versions, the E39 is now recognized as a classic. Surviving examples are meticulously maintained by enthusiasts who appreciate the raw mechanical nature of the vehicle. The combination of a high-revving engine, engaging driving dynamics, and elegant European styling has cemented its status as a future classic. Values have steadily increased, making a well-maintained example not just a car to drive, but a potential investment.
