AC Schnitzer BMW Z4 Roadster and Coupe

AC Schnitzer Press Release

Now that the Z4 Roadster has undergone a facelift and at the same time the
M-variant, the Z4 M Roadster, was launched, the model range has been completed
with a new Z4 Coupé and MCoupé. Not only BMW but also we at AC
Schnitzer are thrilled with the range of new Z4 vehicles, and present our interpretations:
the AC Schnitzer ACS4 Roadster and the AC Schnitzer ACS4 Coupé.

The product range extends from suspension components and exhaust systems, through
a wide range of wheel and tyre combinations, to special aerodynamic conversions
and last but not least interior accessories.

The aerodynamic range has been designed so that – with few exceptions – the
special accessories for the ACS4 Roadster will also fit the ACS4 Coupé,
and similarly the conversions for the ACS4 M Roadster are compatible with the
ACS4 M Coupé.

To improve the driving dynamics, for the Z4 M Roadster and M Coupé we
offer a modified rear axle ratio of3.91 : 1 (standard 3.62 : 1). The AC Schnitzer
rear axle ratio guarantees greatly improved acceleration.

The response behaviour is improved on all Z4 models thanks to the AC Schnitzer
sports rear silencers. Made completely of special steel with chromed Racing
tailpipe, they also provide a more sonorous note than the standard system. For
purely visual enhancement, on the Z4 Roadster and Coupé chromed tailpipe
trims are available in the same design.

For the M-versions of the Z4 that are fitted with a twin sports silencer as
standard, as well as the Twin Racing system there is a further option of Sports
Trim Design. This design is reserved exclusively for M-vehicles and was previously
seen on both the M5 and M6.

Faster and more precise gear shifts promote the adrenalin rush and perceptibly
improve acceleration in a car. So the AC Schnitzer Short Shift has been adapted
for the BMW Z4 3.0i, 3.0si and M-versions with manual transmission.

For safe control at all times of the driving performance of the new BMW Z4
models, except M variants, a special high performance brake system has been
developed for the front. The internally vented and slotted brake discs measure
334 mm in diameter and are 32 mm thick. The special brake calipers are fitted
with two 42 mm pistons. Naturally the standard ABS system is retained in full.

Extensive tests on race tracks and public roads have resulted in the development
of a complete suspension concept consisting of AC Schnitzer sports suspension,
special antiroll bar kit and strut braces. The total concept, the components
of which can also be fitted individually, achieves sports handling with the
same high standard of driving comfort.

In addition, exclusive to the M Roadster and M Coupé is a special racing
suspension which is currently still in the development phase.

The suspension concept for all ACS4 Roadster and Coupé models naturally
also includes the AC Schnitzer Type IV, Type III and Type II alloy and racing
rims in one-piece and multipiece construction. As well as a wealth of wheel
and tyre combinations in 17", 18" and 19", we can now offer the
largest wheels for the Z4 Roadster and Coupé in 9.0J x 20" with
tyres 245/30 R 20. The M Roadster and M Coupé are even fitted with 9.0J
x 20" and 245/30 R 20 on the front and 10.0J x 20" with 285/25 R 20
on the rear. For tyres, we recommend high performance tyres from Continental
and Michelin.

The bodywork of the AC Schnitzer ACS4 models reveals the high technical standards
that we apply to our products. So for the Z4 Roadster and Coupé and for
the M Roadster and M Coupé there are two tailored outfits that fulfil
these attributes.

The front part of the Z4 Roadster and Coupé is enhanced by the strikingly
designed front spoiler attached to the standard front skirt. This also ensures
better downforce. The rear is rounded off by the new AC Schnitzer rear skirt
which not only harmoniously integrates the sports rear silencer into the rear
but at the same time gives the vehicle a more imposing appearance.

It is in the nature of things that there are a few fundamental differences
between the Roadster and Coupé: for the Roadster the product range includes
a chrome cover for the roll bars, a wind deflector in clear-glass style and
a two-piece rear wing, the triangular parts of which are attached individually
to the right and left of the Roadster boot – setting totally new accents.

Whatever the body version, the AC Schnitzer side skirts form the homogeneous
link between the front and rear. A particular eyecatcher is the side deflectors
with integrated flashers, which as an option can be supplemented with a Chromeline
set.

Exclusivity is the trump card in the cockpits of all AC Schnitzer ACS4 models:
As well as the carbon interior trim in silver, and matching ergonomically designed
AC Schnitzer airbag sports steering wheels, the accents are set above all by
the aluminium accessories in silver or black anodized finish. There is also
a pedal set with matching foot rest, a handbrake handle and a selector knob
for the manual versions. For automatics, there is a carbon selector lever. Last
but not least, foot mats with the AC Schnitzer logo, made from high quality
velours, complete the range.

Naturally all AC Schnitzer parts are TÜV-tested.
