The fifth concept car of the “TUNE IT! SAFE!” VDAT initiative has been designed mainly by BMW tuning specialist AC Schnitzer

“Only serious, safe tuning will bring the hoped-for driving pleasure!“ Under this motto, the Association of German Car Tuners (VDAT) every year launches a special concept car. In 2010, BMW AG is providing a BMW 123d Coupé for the Association’s “TUNE IT! SAFE!“ initiative, which is also supported by the Police and the Federal Ministry for Transport, Building and Road Development. Most of the vehicle accessory equipment has been supplied by Aachen-based BMW tuning specialist AC Schnitzer.

As in the last four years, a police vehicle has been professional converted as part of the promotion. The AC Schnitzer “ACS1 2.3d“, based on the BMW 123d Coupé, shows that safe tuning is far from boring. VDAT-member AC Schnitzer has upgraded the 2.3 D engine to 241 HP (177 kW) and 480 Nm. The police car with 6-speed automatic transmission now accelerates from 0 to 100 km/h in 6.7 seconds, so would acquit itself well even in the fastest pursuit. The latest AC Schnitzer wheels Type IV BiColor are fitted with tyres from TUNE IT! SAFE! main sponsor Hankook. The low, safe road position is achieved with the sports suspension from the Aachen-based specialist with 30 mm lowering. The bodystyling kit consists of two-piece front spoiler, rear skirt insert, rear wing and rear roof spoiler. Good visibility is ensured by the “LEDayFlex“ modern daytime running lights from Hella, and optimum rearward vision by the AC Schnitzer “New Generation” sports mirrors.

In the interior, the guardians of the law could enjoy leather racing bucket seats with AC Schnitzer logo and silver genuine carbon fibre trim on the dashboard, centre console, door handles and steering wheel, which are perfectly complemented by the aluminium pedals and aluminium foot rests. A further highlight is the G-force indicator, which measures and displays the centrifugal forces inside the car.

The concept car impressively demonstrates large parts of the tuning accessory range from AC Schnitzer. To give the BMW the essential, authentic look of a “real” police car, Foliatec supplied the original stickering and Hella the flashing lights. Even the police could – and would like to – drive the converted vehicle in public road traffic. To their regret however, the concept car will not be brought into use and is not available in this complex form. Nonetheless, it makes an important contribution towards achieving the aim of the initiative: to combat illegal, unsafe tuning and counterfeiting. All AC Schnitzer conversions are however available commercially and are of course TÜV-approved.

The AC Schnitzer “ACS1 2.3d Coupé“ will be on display for the first time at the Essen Motor Show on VDAT Stand No. 406 in Hall 10 from 28 November to 6 December 2009. “Serious and safe tuning is not only a company philosophy, but it is also our mission“, emphasises Rainer Vogel, Managing Director of AC Schnitzer. And you can take this literally: Safe tuning with components from a reputable manufacturer not only brings the desired driving pleasure, but can even be lifesaving.

The BMW Z4 as standard is far from under-powered. But as is well known, enthusiastic drivers can never have enough power. Sufficient reason then for AC Schnitzer to upgrade the Z4 3.5i Turbo to 286 km/h. With a power of 360 HP and an unladen weight of 1485 kg, the open-top roadster from BMW accelerates from a standing start to 100 km/h in just 4.9 seconds. Even the most demanding driver will be delighted with this performance.

The driving experience is enhanced acoustically and visually by the stainless steel sports rear silencer and the chromed Racing tailpipe trims.

Equally sporting is the AC Schnitzer suspension variant in the Z4. Thanks to a new spring kit, the transverse acceleration appears to bypass the conventional laws of nature.

This impression is certainly partly supported by the aerodynamic components made of PU-Rim, a high quality flexible plastic. The aerodynamic pack for the new BMW Z4 consists of a chrome front grille and front spoiler, where both components combine to give a more muscular look to the long bonnet lines.

New sports fenders, consisting of wheel arches with integral air outlets for improved cooling of the front brakes and chromed deflectors, optimise the side lines of the roadster.

Finally, the two-piece rear spoiler gives the rear of the BMW Z4 by AC Schnitzer an impressive look; because of the performance of the car, this is probably the aspect which will be seen most by other drivers!

In the inside, both driver and passenger enjoy an impressive interior. The aluminium cover for the i-Drive System Controller, the aluminium foot rests and pedal set, are just a few of the ergonomically perfect controls which give the vehicle elegance and enhance the sporting ambience.

Standing on AC Schnitzer Type IV in 18” or Type VI wheels in 18, 19 or 20 inch, the BMW Z4 takes to the stage for its world premiere. A striking entrance from the Aachen specialist, which will certainly not be forgotten in a hurry.

“The new model is certainly the most dynamic 7-series ever, so we’ve only made subtle changes to the outline“, explains AC Schnitzer Chief Designer Michele Viandante. His philosophy: “Our accessories set important accents and emphasise the sporting characteristics of the saloon in a targeted manner.“ These are already written large in the imposing front, which is emphasised by a new AC Schnitzer spoiler element. Michele Viandante’s tip: The through lip elongates the front and gives the car a faster look.

Like all accessories from AC Schnitzer, it is made of very hardwearing, well-fitting PU RIM. Subtle but striking also describes the effects of the side enhancements: “The result must be a harmonious ensemble, and not a combination of trainers and tuxedo“, says Viandante. The AC Schnitzer side skirts attachments emphasise the car’s wheelbase and lengthen it visually, giving it a more purposeful appearance. Towards the rear third, they are lifted and widened to give the car a more muscular look.

This is no bluff, because the new 7-series has plenty of power under the bonnet in every version, even when the music’s playing at the back. The sight of AC Schnitzer tailpipes is as striking as the sound: two exhaust channels come together in a slightly rounded, chromed trapezoid trim – all very individual. But that’s not enough for sporting attributes. Between the exhausts, Michele Viandante has introduced a further spoiler element which with its diffuser style symbolises pure dynamics. Only the subtle boot spoiler and rear roof spoiler remain to complete the look.

AC Schnitzer knows how to enhance a saloon’s sporting aura without losing its elegance. Then the final touch is down to customer taste:

There’s a choice of countless exciting AC Schnitzer wheels for the new 7-series. Two particularly striking examples: the Type V alloy with its clear, transparent five-spoke design, which celebrates its world premiere in 22″ on the 7-series and is also available for X5 and X6. Or the multispoke Type VII, also available in 22″. Both versions not only show true greatness, but constitute the perfectly balanced combination of per
