Research Dossier — 1955 Mercedes-Benz W196 Monoposto
Context. Mercedes returned to Grand Prix racing in 1954–55 with the W196 in both streamlined and open-wheel forms. The Monoposto open-wheel version carried drivers like Juan Manuel Fangio and Stirling Moss to victories during the 2.5-litre formula.
Powertrain & chassis. Spaceframe chassis with a 2.5-litre straight-eight using mechanical fuel injection and desmodromic valve actuation; ~250+ hp period output. Five-speed transmission with inboard rear drum brakes and torsion-bar suspension.
Design signatures. Low rounded nose with oval intake and fine mesh, faired “blank” headlamp covers (carry-over from streamliner), side-exit exhaust on the right, slab sides with roundels, wire wheels/knock-offs, and a tapered cigar tail with headrest hump.
Cockpit. Narrow single-seat tub with plaid or leather seat, large 3-spoke wheel, simple analog gauges and external shifter gate.
