AC Schnitzer Mini Cabriolet

With the  introduction of the MINI Convertible the range is now complete, and for AC Schnitzer the logical consequence was to offer for all MINI models – either Convertible or hard top – a special accessories range which leaves nothing to be desired.

The standard engine of the MINI Cooper S which thanks to compressor technology already delivers a considerable 125 kW / 170 HP, has been given a substantial boost by the AC Schnitzer engineers who have optimized the compressor ratios and at the same time adapted the Control Unit Program. After the AC Schnitzer treatment, the 1.6 l power plant delivers a stately 142 kW / 193 HP at 7000 rpm. In this guise, the MINI Cooper S by AC Schnitzer covers the 0 – 100 km/h sprint in just 7.0 seconds, and has a top speed of 235 km/h.

To improve response, the performance upgrade is offered in conjunction with the AC Schnitzer sports rear silencer made completely of stainless steel with chromed racing tailpipe trim and the corresponding engine highlights in stainless steel.

For the MINI One D too, we have developed a diesel performance upgrade which delivers 66 kW / 90 HP and takes the maximum torque to 220 Nm at 2000 rpm.

Naturally conversion to the AC Schnitzer rear silencer is recommended even without the engine upgrades. But the customer faces a difficult choice. For both the MINI One and the MINI Cooper there are two variants available: a twin exhaust system with two oval tailpipes in right/left combination or the single oval tailpipe design.

The third variant is reserved for the MINI Cooper S: a sports tailpipe in centre positioning, in the design of the AC Schnitzer Racing tailpipe trim.

Whatever variant he chooses, the customer is guaranteed to enjoy the throaty sound and attractive integration of the exhaust into the rear of the MINI.

Last but not least, for aesthetic enhancement of all MINI models (except the Cooper S) the chromed tailpipe trim with oval end is available.

The AC Schnitzer rear skirt not only integrates the silencer but at the same time gives the MINIs (except the MINI One D) a far more powerful look.

Also available for the front is a complete skirt, which thanks to the generously dimensioned front grille with chrome frame gives the MINIs a bright new facial expression. But the aerodynamic conversion is not just an aesthetic improvement. Made from high quality PU-Rim, it gives improved downforce and is easy for paint and fit.

The exterior program is completed by the designer stripes and the AC Schnitzer logo “Technology & Design”, available in white or black or, for the Cooper S, with a red “S”.

An absolute eyecatcher – for both the exterior and the interior observer – is the AC Schnitzer fold and slide roof, which offers a genuine alternative to the Convertible. With an opening of 710 x 810 mm, it provides a true fresh air experience despite the “hard top” design.

The driving dynamics of all MINI models are further improved by suspension components which lower the vehicle by around 30 mm in conjunction with the AC Schnitzer Type I alloy wheels in 7.5J x 17″ with tyres 215/40 R 17.

For all MINI models, a height-adjustable racing suspension is available together with suspension spring kits for pure lowering. The suspension concept is completed for the Cooper S variants by the AC Schnitzer aluminium strut brace for the front which further stabilizes the front end on tight corners or sudden swerve manoeuvres.

So it’s no surprise that the subjective driving impressions are reminiscent of a Go-Kart, especially on twisty roads or at high speeds. For tyres, we recommend high performance tyres by Continental and Michelin.

The famous dot on the “i” comes from the interior components such as e.g. the aluminium pedal sets with matching foot rest cover, the aluminium gear knob and the aluminium handbrake handle. Last but not least, special floor mats are available with a 2-colour embroidered AC Schnitzer “Technology & Design” logo.

Finally, AC Schnitzer offers tailor-made solutions in the fields of traffic telematics and Car Infotainment which can be integrated optimally.

AC Schnitzer ACS4 based on BMW Z4

Most people demand as high a standard from their car as they do from their life partners. Firstly it must have innumerable inner values - in a car of this class, you expect pure performance. Secondly it must also have an extremely attractive external appearance. When the two come together, things can quickly get serious. This happened to us with the Z4. But after love at first sight, the first doubts started to appear, and suggested improvements followed. So the AC Schnitzer specialists set out to develop true love on wheels: The AC Schnitzer ACS4.



For the power plant of the most powerful variant at present - the BMW Z4 3.0i - a performance upgrade is already “in the pipeline”. A development achieved in close collaboration with the BMW Motorsport Team Schnitzer, Freilassing.



The power of the AC Schnitzer ACS4 is increased by supercharger technology. The heart of the upgrade is a turbine supercharger which thanks to its toothed belt drive allows almost noiseless running. Only in the upper speed ranges is the characteristic compressor note - totally desirably! - produced.

The geometric design of this supercharger means it only needs maximum 38.000 rpm to achieve a boost pressure of 0.35 bar at an engine speed of 6.500 rpm. This increases the output of the standard power plant to a stately 295 HP / 217 kW and brings the maximum torque up by 80 Nm.



Thanks to the excellent efficiency of the supercharger, there is no need for an extra charge cooler. The high-tech bearings are permanently lubricated via an autonomous, dedicated oil reservoir. This has the advantage of allowing the two oil circuits to work independently.



The scope of supply of the AC Schnitzer Compressor performance upgrade also includes the full stainless steel AC Schnitzer sports rear silencer with chromed tailpipe trim in the new racing design, a modified control unit program and a carbon fibre valve cover. The performance upgrade is naturally also available for other vehicles with the M54 B30 engine.



Even without the engine tuning - for the BMW Z4 2.5 or 3.0i - we recommend fitting the AC Schnitzer sports rear silencer which optimises gas flow and hence response behaviour. As a “smaller alternative” the tailpipe trim in racing design completes the package.



Faster and more precise gear changes promote the adrenalin surge and improve the car’s acceleration. So for the manual BMW Z4 3.0i we have adapted the AC Schnitzer Short Shift.



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



Our engineers also invested great efforts and their entire know-how from motorsport in developing the sports-safe suspension setting.



In extensive tests on race tracks and on public roads, a complete suspension concept has been developed which consists of the AC Schnitzer sports suspension, special anti-roll bar kit and the racing strut brace. The complete concept, the components of which can also be fitted individually, ensures sporting handling while retaining the high standard of driving comfort.



The suspension concept also includes the latest AC Schnitzer development in wheels: the light alloy wheel Type IV. The filigree rims in the new 5-spoke design are an excellent match for the elegant styling of the BMW Z4. Naturally their technical standards live up to their appearance: the new Type IV alloys were developed using highest quality materials and ultra-modern production techniques.

It is immediately available for the Z4 in the dimension 8,5J x 19″ offset 43 (front) and offset 33 (rear) with tyres 235/35 R 19 (front / rear).



The AC Schnitzer wheels program with its successful predecessors Type II and Type III light alloy and racing wheels is of course also still the right choice. Especially for the Z4 roadster there are many different sizes available up to the dimension 8,5J x 19″ offset 43 with tyres 235/35 R 19 for the front and 9,0J x 19″ offset 37 with tyres 265/30 R 19 on the rear. We recommend high performance tyres from Continental and Michelin.



The high technical standards we set for our products are also evident from the bodystyling of the AC Schnitzer ACS4 roadster. It was a particular challenge to pick up the styling of the Z4 roadster and continue its lines with subtle emphasis while retaining its discreet elegance.



The result is a made-to-measure outfit for the BMW Z4 roadster which fulfils all these attributes. The front part is enhanced by an exciting design of front spoiler attached to the standard front skirt. And it realises even more downforce on the front axle.

The smooth connection between the front and rear is created by the AC Schnitzer side skirts adapted to the contours of the Z4. The integrated cooling ducts also guide the air flow directly to the rear brakes.

Particularly eye-catching are the side-mounted deflectors with integral flashers for the indicators, which can be ordered with a chromeline set consisting of chromed ribs giving a totally new appearance. Matching to this, chromed covers for the standard roll over bars have been developed.



The two-piece rear wing, the triangular sections of which are mounted separately left and right on the boot, sets totally new accents. The overall appearance is rounded off by the new AC Schnitzer rear skirt, which not only harmoniously integrates the sports rear silencer into the rear end but at the same time gives the vehicle a far more powerful look.



Exclusivity is the watchword in the cockpit of the AC Schnitzer ACS4 roadster: as well as a silver carbon-fibre interior and an ergonomically designed AC Schnitzer airbag sports steering wheel, the accents are set by the aluminium accessories. Choose from the pedal set with matching footrest, the handbrake handle and - for manual models - matching gear knob. For automatics we have developed a carbon-fibre selector. To fulfil wishes for more sporty seats AC Schnitzer now offers the modification of the standard seats. They get an even new contour by upholstery so that driver and passenger have more lateral support.
