H AC Schnitzer άφησε στην άκρη τα βελτιωτικά πακέτα για τα αυτοκίνητα της Mini και της BMW και βελτίωσε το ποδήλατο M Carbon Racer της BMW. Το περιγράφει ως μια εντυπωσιακή επίδειξη μείωσης βάρους, αφού ζυγίζει 6.9 κιλά, 1 λιγότερο από όσο ζυγίζει κανονικά. Διαθέτει carbon σκελετό, και σε σχέση με το εργοστασιακό ποδήλατο, διαθέτει carbon σέλα, τροχούς και μανέτες των φρένων. Σύμφωνα με την AC Schnitzer, το ποδήλατο διαθέτει καλύτερη δυναμική συμπεριφορά και μειώνει την καταπόνηση του αναβάτη.

Lightness in Bikes: The BMW M Bike Carbon Racer by AC Schnitzer
Weighing less saves energy and protects the environment. In vehicle construction, the aim is more than ever to develop lightweight components. Lightweight construction also achieves an improvement in dynamics, so it’s no wonder that lightweight construction is one of the core skills of the tuning experts at AC Schnitzer.
The Aachen-based company impressively demonstrates the potential for weight saving by the lightweight construction of the BMW M Bike Carbon Racer by AC Schnitzer.
Exceptionally, the new project concerns an unmotorised vehicle powered by muscle power alone.
All the more important then is the 12.7 percent weight reduction which the tuning specialists have succeeded in making on the racing bike. Now weighing just 6.9 kg – instead of the 7.9 kg as standard – the riding dynamics of the BMW M Bike Carbon Racer have perceptibly improved.
“Lightness in Bikes” has been achieved by replacing components: new carbon wheels were developed in collaboration with the specialist “Xentis”. The carbon saddle and the carbon saddle support combined with a carbon crank, reduce the weight and maximise the dynamics for the same muscle power of the rider.
The equivalent to the cyclist’s muscle power for the bike is the engine in the BMW and MINI models by AC Schnitzer. And here too, AC Schnitzer is dominant with improved dynamics thanks to weight reduction.
For example, the AC Schnitzer 99d based on the BMW Z4 SDrive 23i has been trimmed by a solid 230 kg. From a standing start, the vehicle with its 190 HP accelerates to 100 km/h in just 6.9 seconds. Despite the top speed of 235 km/h, the fuel consumption can still be held at just 3.8 litres diesel per 100 km with emissions of 99 g CO2.
The same applies to the AC Schnitzer RAPTOR based on the MINI Cooper Works Coupé. 100 kg weight reduction makes the pocket rocket the fastest MINI at Hockenheim, even leaving a Porsche 911 Turbo S in its wake.
An important component in the weight saving is the wheels. AC Schnitzer achieved a saving of 25 to 35 % by developing the lightweight forged alloys Type V and Type VIII, in comparison with conventional cast wheels. The lower centrifugal forces on the axles ensure perceptibly improved handling, and the savings in unsprung mass have a four-fold effect on the driving dynamics.
For over 25 years now, the Aachen-based specialists have developed many different vehicle models and tuning components in lightweight construction, now including the BMW M Bike Carbon Racer by AC Schnitzer. Motorised or by muscle power: for AC Schnitzer, lightness is the way to improved dynamics and enhanced pleasure on the road.
