Historical Context
Pre‑E39 M5 Evolution
Prior to the E39 generation, the M5 lineage had seen two distinct evolutionary paths. The E24 M5 (1979‑1985) introduced the iconic twin‑turbocharged inline‑six, delivering a 240‑horsepower output that set the tone for BMW’s performance sedans. The subsequent E28 M5 (1986‑1991) retained a naturally aspirated inline‑six but with an increased displacement of 3.5 liters, producing 260 horsepower. By the late 1980s, BMW’s competitors were beginning to explore V8 powertrains in their own high‑performance offerings, and BMW’s engineering team identified a need to modernize the M5 platform to keep pace with evolving market expectations.
The decision to shift to a V8 for the E39 M5 was driven by multiple factors: increased power density, smoother operation, and the ability to incorporate more advanced electronic controls. This strategic move positioned BMW to compete directly with the likes of the Mercedes-Benz E‑Series 280 SEL, the Audi S6, and the Lexus GS 350, all of which had begun to incorporate V8 powerplants in their performance models during the early 1990s.
Development Process
The development of the E39 M5 began in the early 1990s under the guidance of BMW’s Motorsport department. Engineers focused on a balance between performance and everyday usability, aiming to create a vehicle that could deliver exhilarating acceleration while remaining comfortable for daily driving. The prototype phase tested variations of the M62 V8 engine, examining tuning strategies for displacement, cam profile, and exhaust system design. Additionally, the development team conducted extensive simulations to refine suspension geometry, steering responsiveness, and braking performance.
Collaboration with the chassis and dynamics teams led to the introduction of the first active suspension system in a production sedan. The Adaptive Variable Suspension (AVS) allowed the vehicle to adapt ride characteristics in real time, adjusting damping rates to match road conditions and driver input. This innovation was key to achieving the dual objectives of sporty handling and high‑level ride comfort.
Mechanical Layout
Chassis and Body Structure
The E39 M5 shares its underlying architecture with the standard E39 sedan but incorporates several structural enhancements to manage increased power and stiffness demands. The chassis incorporates reinforced aluminum and steel panels, especially around the engine bay and suspension mounting points, to reduce flex under high torque loads. A reinforced cross‑member and additional frame braces ensure rigidity throughout the wheelbase, contributing to improved handling precision.
The body panels feature a combination of high‑strength steel and aluminum to maintain a lightweight profile. A 19‑inch wheel hub design was used for the M5, coupled with wider tires for enhanced grip. The overall weight of the vehicle averages 1,860 kilograms (4,100 pounds), with a dry weight slightly lower for the competition edition. Despite the increased power output, the weight distribution remains balanced, achieving a front‑rear ratio of approximately 53:47.
Engine and Powertrain
The core of the E39 M5’s performance lies in the 4.4‑liter M62 V8 engine, developed under the codename “M62S.” This naturally aspirated engine features a bore of 94.6 mm and a stroke of 80.5 mm, generating 300 horsepower (225 kW) at 6,600 rpm and 310 Nm (229 lb‑ft) of torque at 4,400 rpm. The engine is equipped with twin overhead camshafts per bank, 16 valves, and a dual‑jet throttle system that allows for precise air‑flow control.
Fuel delivery is managed by an electronically controlled throttle body, while the engine management system uses a high‑precision mass airflow sensor and manifold absolute pressure sensor to optimize combustion. The M62 engine’s compression ratio of 10.0:1 and a 10.7:1 air‑fuel ratio at peak torque ensure efficient combustion and power delivery. An oil cooler, high‑flow fuel injectors, and an intercooler were not part of the standard configuration, but they were integrated into specific special editions and later models.
Transmission and Drivetrain
The E39 M5 employs a six‑speed manual gearbox as its standard transmission, featuring an overdrive ratio to improve fuel economy at cruising speeds. The gearbox’s gear ratios are engineered to complement the engine’s powerband, offering a close gear spacing that enhances acceleration. The manual transmission’s clutch assembly is a multi‑piece, double‑disc clutch system designed for durability and smooth engagement.
All‑wheel‑drive capability was not offered on the M5, maintaining the sedan’s rear‑wheel‑drive layout that BMW has traditionally favored for performance models. Traction control, a part of BMW’s Integrated Vehicle Dynamics (IVD) system, uses wheel‑speed sensors to modulate power delivery to the rear wheels, reducing wheel spin and improving acceleration from various launch conditions.
Suspension and Braking
Suspension geometry in the E39 M5 includes a double‑wishbone front and a multi-link rear arrangement, allowing for precise camber control throughout the suspension travel. The vehicle’s Adaptive Variable Suspension (AVS) system can adjust damping rates between a firm, performance mode and a compliant, comfort mode. This system uses a hydraulic actuator to alter damper characteristics in real time, enabling the vehicle to adapt to changes in driving style or road surface.
The braking system consists of ventilated disc brakes front and rear, with a larger front rotor diameter to aid in heat dissipation. Brake pads are made from a high‑friction material, providing robust stopping power and a characteristic “kick” that many enthusiasts appreciate. ABS and Electronic Brakeforce Distribution (EBD) further augment the safety and effectiveness of the braking system.
Performance and Handling
Acceleration and Top Speed
The E39 M5’s powertrain and chassis configuration allow it to accelerate from 0 to 100 km/h (0 to 62 mph) in approximately 5.8 seconds. Quarter‑mile times hover around 14.4 seconds at a speed of 109 km/h (68 mph). Top speed, electronically limited to 250 km/h (155 mph), can be reached in under 9 seconds from a standstill. These figures place the E39 M5 firmly within the high‑performance class for its era.
Acceleration curves are characterized by a linear power delivery profile, with a slight dip in the mid‑range due to the engine’s design focus on high‑rpm power. The manual transmission’s close gear ratios and the high-torque output enable a rapid first‑gear launch, while the overdrive gear facilitates a smooth transition to cruising speeds.
Steering and Dynamics
The steering system employs a rack‑and‑pinion design that offers precise feedback and quick response. The steering ratio is calibrated to deliver a direct feel while maintaining a moderate turning circle, measured at 7.5 meters for the M5. The integrated Traction Control System (TCS) works in conjunction with the Electronic Stability Program (ESP) to keep the vehicle’s directional stability during aggressive cornering.
Dynamic tests reveal that the E39 M5 offers a 70/30 left-right turn bias, with the center of gravity positioned approximately 45% from the front axle. This distribution, coupled with the stiff rear suspension and the front‑rear torque balance, provides a predictable handling response that is appreciated by both casual drivers and track enthusiasts.
