Hyman, Ltd.

The 300 series was designed to compete with Rolls-Royce quality. It was complex, expensive and luxurious, and offered as a huge sedan with optional division windows or as a four-door cabriolet. The 300 was powered by a 115-bhp 3.0-liter six-cylinder engine coupled to a four-speed synchromesh gearbox, and was capable of cruising at 100 mph. The X-frame was built of oval tubes, the front suspension was independent by coil springs and wishbones, and the rear featured Mercedes-Benz’s swing axle. The rear suspension was adjustable at the dashboard and a central lubrication system was foot-operated.
