1936 Mercedes-Benz 540K Special Roadster
The straight-8 cylinder engine of the 500K was increased to 5,401 cubic centimetres (329.6 cu in), which aspirated by twin pressurized updraft carburetors, developed a natural 115 hp (86 kW). Power was sent to the rear wheels through a four-speed or optional five speed manual gearbox that featured synchromesh on the top three gears. Vacuum-assisted hydraulic brakes kept the car under the driver's control.
The 540K had the same chassis layout at the 500K, but was significantly lightened by replacing the girder-like frame of the 500K with oval-section tubes - an influence of the Silver Arrows racing campaign. Only 28 540K Roadsters were made.
