The concept PROFILE by AC Schnitzer based on the Z4 M Coup
Take the first ascent of the 8,848 metre high Mount Everest, the expeditions to the poles or the dive into the 11 km deep canyon of the Mariana Trench. There have always been individuals and extreme characters who have pushed our boundaries and discovered new terrain. An extreme region for automotive tuners, where only a few venture, has always been the BMW M-series cars, in particular the uncompromising Z4 M-Coup, a thoroughbred driving machine.
But the fact that the limits of this extraordinary car are far from reached is evident from the new concept vehicle by AC Schnitzer - the PROFILE - even at first glance. Classic engine tuning hauls the power of the high-revving six-cylinder in-line plant to a robust 350 HP. Not only is a special "active breathing" airbox used, but the engine control unit has been remapped. But power alone isnt enough to get the maximum from an athletic heart. So the modified rear axle ratio of 3.91:1 provides better sprint capacity, while the perfectly smooth transmission with the AC Schnitzer Short Shift ensures crisp changes by the driver.
And as you listen to the sonorous baritone note of the left/right sports exhaust system with the trapezoid tailpipes, you could be deceived into thinking that the driver is not changing gears, but playing some kind of a musical instrument. A feast for all the senses: Visually the stunning colour combination of white-orange casts its spell and perfectly enhances the exquisite contours of the AC Schnitzer bodykit. From the front skirt with its suggestive cup-wings via the widened wheelarches and flanks with the gill-like vents - as already used on the legendary BMW 507- the dynamic line is drawn over the bulging side skirts to the rear skirt with carbon diffuser.
The whole is crowned by a rear spoiler and a fascinatingly styled roof wing. The forged alloy Type V wheels from the standard AC Schnitzer collection are a work of art in themselves. Filigree design yet with an air of solidity, in size 9.0J x 20" at the front and 10.0J x 20" at the rear, these wheels are the perfect adornment combined with tyres size 235/30 ZR 20 front and 295/25 ZR 20 rear.
But traction alone isn`t everything, and the dynamics are supported by the AC Schnitzer suspension with its racing heritage, set up in the Green Hell of the Nrburgring. An aluminium strut brace in "Racing style not only catches the eye but limits the torsion of the front body. Thanks to the AC Schnitzer racing seats, the driver always holds position. And the carbon interior trim and pedal set, with decor elements of aluminium, radiate pure racing flair. Could there be a better place to experience the limits of potential?
