Merzig-based tuning specialist Kelleners Sport has revealed its program for the latest BMW M5, named the KS5-S.
Visually, the aero package includes a lower front spoiler, mirror casings, boot lid spoiler and rear diffuser section – all finished in clear coated carbon fibre, and a pair of sculpted side skirts, while the 20-inch diameter Hamburg alloy wheels have been painted matte black and wrapped in Michelin Pilot Super Sport tyres.
A remapped engine management system along with the newly developed stainless steel exhaust, culminating in four 90 mm tailpipes, allows the 4.4-litre V8 to produce 492 kW (660 hp) and 790 Nm of torque – up from 418 kW (560 hp) and 680 Nm – and enough for a 330 km/h top speed. The rear silencer features an integrated valve that – depending on engine revs – opens and closes automatically. To comply with noise regulations the valve stays closed on start-up, but begins to open up from 4,000 revs. A more raucous Sound+ version is available for export only.
