 It developed a claimed maximum of output at 3,300 rpm, which converted into a top speed of 120 km/h (75 mph).Gone were the light-metal cylinder head and overhead valves that had excited commentators on the Type M. The three-speed manual transmission represented a step back from the four-speed transmission of the earlier car, and while the Type R retained four-wheel brakes, these were now mechanically rather than hydraulically controlled.The Type R also lost some of the earlier car's bulk, its wheelbase being shorter than that of the Type M. The vast Pullmann-Limousine-bodied car was also 200 kg lighter, with an official weight of "only" 2,300 kg.
