2011 Kelleners Sport KS1-S BMW 1-Series M Coupe

Based on the BMW 1-Series M Coupé (Type E82), the Kelleners Sport KS1-S high-revving inline six-cylinder engine with twin-turbochargers boosts the output of the KS Power SW 35M by a good 20 percent. Instead of the standard 340 hp (250 kW), the Kelleners Sport KS1-S produces max. 410 hp (301 kW) while max torque jumps from 450 to 550 Nm. The result is a decline in weight to power ratio from 4.4 to 3.8 kg per hp. And emphasising all this power are special Kelleners Sport rear silencers. With four 83 mm tail pipes, the stainless-steel system is optimised for unrestricted flow and distinguishes the car from the series model with a significantly more exciting exhaust sound.
The aerodynamic components of Kelleners Sport are designed to minimise wind resistance and ensure maximum down-force at high speeds. The MS front spoiler lip and the three-part MS grill insert made of electro polished stainless steel underscore the aerodynamic qualities of the car and create a supplementary visual impact. Naturally, this does not affect the BMW air curtains, which improve the aerodynamics by channelling the air stream around the front wheels. Visually, the improved agility is accentuated by decorative strips on the bonnet, roof and side sills.
The Kelleners Sport light-alloy wheels also contribute to the sporting characteristics and image. The extremely light, one-piece wheels reduce the unsprung weight and thus ensure dynamic handling. At the front, the 9×20-inch wheels are fitted with 245/30 high-performance tyres while the rear axle comes with 10×20-inch wheels and 265/30 tyres. With their 15 elegant spokes, the “Hamburg” wheels are available in the following finishes: polished graphite-silver, polished platinum-silver and matt black. The ‘Berlin’ wheel with slender double spokes is available in platinum silver polished, matt black polished and matt black.
