BMW tuner Kelleners Sport has unveiled their fastest ever sedan, the KS5-S based on the 2012 M5.
The car comes with various improvements out of which the most important are the ones that enable the engine to produce 660 HP and 790 Nm of torque. The extra power results from Kelleners fitting the M5 with a valve-controlled sport exhaust with stainless steel rear silencers and 90 mm end pipes, with these additional 100 HP having a direct impact on the vehicle’s top speed which is now in excess of 330 Km/h.
The Kelleners 2012 BMW M5 also comes with a restrained rear spoiler, carbon coated mirror caps and rear diffuser, custom side mouldings and a front spoiler lip. Other upgrades include 20 inch rims available in three different finishes (graphite silver, platinum silver polished or matt black) and an adjustable suspension, while on the inside Kelleners has covered the seats, dashboard and door panels in leather with grey contrasting stitching and has also embossed the front head restraints with the company’s logo.
We are also talking about carbon coated mouldings, a steering wheel wrapped in perforated leather, black velour floor mats and a set of aluminium pedals.
