E60 S85 - The New M5

Foreword

The new BMW M5 will be launched in

October 2004. It will be the most powerful M5

of all time and the first to exhibit this power

potential at first glance.

The basic concept, however, remains

unchanged: The E60 M5 too combines -

without compromise - the qualities of a luxury

class Saloon with the power potential of a

sports car. Its visual appearance, however, is

intentionally somewhat less discreet as its

predecessor. The front and rear aprons are

now slightly more prominent and, together

with the rear spoiler, 4-pipe exhaust system

and 19" wheels, the in the meantime M5-

characteristic side gills unmistakably identify

the M5 at first glance - even from the side.

The highlight of the new M5 is, of course, the

V10 engine derived from BMW-Williams

Formula 1. With the governed limit at

8,250 rpm, it not only provides Formula 1

performance but also develops that typical

Formula 1 sound.

Despite these features, the M5 still remains an

understatement-product. Its exterior conveys

a powerful yet still reserved appearance. At no

point has its everyday suitability gained from

the E60 series been lost.

The most important features in brief

10-cylinder Formula 1 engine

The V10 all-aluminium naturally-aspirated

engine with 5 l displacement develops

400 bhp output. This output can be increased

to over 500 bhp by pressing the power button

on the centre console.

As in the Formula 1, the bedplate structure

ensures low-vibration stability with matching

rigidity. The engine is controlled by the

Siemens MS_S65 engine management while

the knock control is based on ionic current

technology.

The 2-disc dry clutch also stems from

Formula 1, while the gears are shifted with a 7-

speed SMG 3 gearbox specifically adapted to

the high speed concept.

Despite these impressive performance data,

the E60 M5 conforms to the exhaust emission

standard EU4.

Body and suspension

Prominent front and rear aprons, paired with

side sills and a powerful rear spoiler clearly

distinguish the M5 from the E60 Series. A rear

diffuser - also a Formula 1 offshoot - provides

an additional power boost on the rear axle.

With the push of a button, the new DSC on the

M5 provides substantially greater lateral force

for fans of the controlled drift. The rear axle

lock is not fixed at 25% but rather provides

variable control.

Control and individualization

The buttons on the shift lever can be used to

vary the performance control systems. The

accelerator pedal characteristic, EDC and

Servotronic can be individually configured and

selected by means of M-buttons on the

steering wheel. The head-up display is

specifically adapted to the M5 environment.
