Mercedes-Benz 300 W186

The body of the 300 was mounted on a crucible oval-tube chassis. Much like its predecessors, it had a twin-pivoting swing-axle with double coil springs at the rear but also additional torsion bars for each wheel, which could be actuated by a dash-mounted servo if heavy loads were being carried. This stiffened the rear suspension by some 33% when activated. The 300’s 2,996-cc six-cylinder engine featured a chain-driven overhead camshaft along with cast iron block and light-alloy cylinder head. Of particular interest was the use of a sloping head arrangement with the joint face between the block and cylinder head angled 30 degrees. This permitted larger diameter valves, which contributed to better breathing in an engine designed for high-speed use. An automatic choke was fitted to the twin Solex dual downdraft carburettors, an advanced feature for European cars. This is yet another reminder of the American influence on the design and intended market of the 300.
