BMW E39 M5 V8

Due to its popularity the BMW E39 M5 V8 was not hand built in order to speed up production between the years 1998 to 2003 which in this time period 20,482 cars were manufactured at the Dingolfing plant in Germany, replacing the E34 M5 series.

The cars were powered by a 4.9 litre S62 V8 engine coupled to a 6 speed manual gearbox. The wheelbase was 2830 mm, length 4783 mm, width 1801 mm, height 1412 mm with a dry curb weight of 1826 kg.

Mercedes-Benz and Jaguar unleashed high output engined cars in excess of BMW’s initial M5 E39 V8 which had an output of only 210 kW or 282 bhp. BMW responded to the competition with a 294 kW or 394 bhp M5 making it more appealing to the motorsport enthusiasts market worldwide.

Introduced in 1998 production did not begin until October that year. BMW M produced three versions of the E39 M5 which had highly tuned V8 engines based on the M62 called the S62 which was a 4.9 litre motor, producing 294 kW or 394 bhp. The engine featured a 7,000 RPM Double VANOS cylinder head and bottom end which controls the intake and exhaust valves by varying timing for both cylinder bank camshafts including individual throttle bodies for each of its eight cylinders thus allowing much quicker engine response.

All E39 M5s were equipped with a Getrag ‘Type D’ 6 speed manual gearbox also used in the E39 540i, but with a better and stronger clutch which provided the car with a balanced motorsport gear shift and ratio. Included in the setup was a shorter 3,15:1 limited slip diff with 25% maximum lock up. The suspension shared its basic aluminium-intensive MacPherson multi link design with several changes made to like reduced spring height which made the car 23 mm lower.

All E39 M5 models were equipped with an overall steering ratio that was reduced to 14.7 from 17.9 and featured a Servotronic vehicle-speed-sensitive power assist which provides two levels of resistance. The system is controlled via console mounted Sport button which also adjusts the electronic throttle butterflies for faster throttle response.

For the subsequent two model years, changes were limited to the addition of new exterior colors and the upgrade to a DVD navigation systems.

The cars are also equipped with four ventilated disc brake rotors and calipers, measuring 345 mm in the front and 328 mm in diameter for the rear discs. On European spec models the rotors are of a "floating" two-piece design. Anti-lock brakes, EML or fly-by-wire throttle control and Dynamic Stability Control (DSC) were standard features on the cars.

Official performance BMW figures are typically conservative and many reviewers claim to have achieved this under 0-100 km/h in 4.5 seconds and the less restricted versions clocked at 4.6 seconds. Cars are electronically limited to a top speed of 250 km/h.

Since the start of production an E39 M5 Touring was considered but BMW M decided not to produce the E39 M5 Touring due to financial considerations.
