From lightweight concept to pure reality - the new BMW M3 CSL

A lighter, more powerful version of the legendary BMW M3 is ready to set pulses
racing in the UK. First unveiled at this year's Geneva Motor Show in March, the
new M3 CSL is even quicker and more responsive than its thoroughbred cousin,
promising driving purists the most authentic motor sport experience in a
production car.

A limited run will be built in Munich between June and December this year. Five
hundred are destined for the UK and dealer order books are already full. First
deliveries of the car, which is priced at £58,455 on-the-road, will begin in
August.

In creating the M3 CSL, which stands for Coupe, Sport and Lightweight,
engineers at BMW's M division succeeded in stripping 110 kg from the M3. The
result is a car that benefits from an impressive power to weight ratio of just
3.85kg/bhp and accelerates from 0?62 in 4.9 seconds. Top speed is
electronically limited to 155 mph, but can be de-limited for holders of a
racing licence.

But the M3 CSL, which is based on a concept first shown at Frankfurt in 2001,
is not just about lighter materials. Designers were tasked with creating a car
true to BMW's motor sport heritage, right down to the last component. And by
engineering a range of power and handling improvements, BMW has created a
vehicle capable of breaking the eight minute lap time at the famous
Nurburgring, North Circuit in Germany.

So how did BMW create the M3 CSL?

Intelligent lightweight technology:

For optimum weight reduction, BMW M engineers turned to 'intelligent'
lightweight technology. This meant matching the most appropriate materials to
the component or assembly requirements and resulted in widespread use of carbon
fibre reinforced plastics, lightweight aluminium and glass fibre plastics. Much
of this technology has been transferred from Formula 1.

Award winning engine - made better:

BMW's M3 engine has just received its third accolade in a row at the 2003
International Engine of the Year Awards. Now an enhanced version of this
3.2-litre straight-six power house, has been developed for the M3 CSL. Power
output has been boosted from 343 to 360 bhp at 7,900 rpm, while torque is up
from 365 to 370 Nm at 4,900 rpm.

The enhancements include:

· Thinner exhaust walls
· Larger air intake opening and carbon fibre air collector
· Camshafts with longer valve opening periods
· Air intake and volume calculated according to F1 principles
· Optimised exhaust valves
· Modified exhaust emission manifold

M3 CSL gearbox:

BMW M3's most sporting and dynamic transmission features on the M3 CSL - the
paddle shift SMG gearbox with Drivelogic and new software. Based on F1
technology, it allows ultra-fast shifting through all six gears, using the gear
stick or paddles, with changes taking just 0.08 seconds. Drivers can choose
between sequential and automated mode.

Handling dynamics:

Precision handling comes courtesy of a wider front track and modified
suspension geometry, including bespoke springs and dampers. A more direct ratio
for the rack-and-pinion steering (14.5:1, compared to 15.4:1 for the M3) offers
greater steering response in all conditions. While substantially modified
brakes slow the M3 CSL to a standstill from 62 mph in less than 34 metres -
just seven and a half car lengths.

Driver aids:

M Track Mode is a unique function of Dynamic Stability Control (DSC), activated
via a steering wheel mounted switch. This allows skilled track drivers to push
the car to the absolute limit of transverse and longitudinal acceleration, with
DSC operating only where these limits are exceeded.

The optional 19" wheels and tyres for the BMW M3 are fitted as standard but
Michelin Pilot Sport Cup tyres, with asymmetric treads developed especially for
the M3 CSL mounted on unique alloy wheels, can be specified as a no cost
option. The tyres, which are suitable for both road and track, measure 235/35
ZR 19 at the front and 265/30 ZR 19 at the rear. Complementing the performance
of the car, they offer outstanding lateral grip, up to 1.6g, improving the M3
CSL's already remarkable handling qualities and cornering capability.

To ensure M3 CSL owners are comfortable with the handling of these specially
designed optional tyres, dealers will explain the need for caution while they
warm up and during very poor weather. Buyers will also be required to confirm
that they are aware of and understand the unique performance characteristics.

Free driver training for all M3 CSL customers is also included in the price.
Worth £850, this offers drivers a day at the Pro-Drive Live circuit, driving
under the guidance of experienced racing drivers, learning how to get the most
out of the car.

Interior:

In the cockpit, the M3 CSL follows the principles of a genuine sports car.
Options are kept to a minimum, with a focus on the functional, like contoured,
glass fibre bucket seats, offering optimum side support in fast bends.

Centre console and door trims are made of carbon fibre reinforced plastic and
the M Sports steering wheel is clothed in Alcantara. To make best use of the
reduced weight potential many features of modern cars normally considered as
essential, such as air conditioning and a radio, are excluded from standard
specification, but can be specified as no cost options if the customer wants
them.
