Arguably the world’s first
supercar, the iconic 1954 Mercedes 300SL “Gullwing” was
Mercedes-Benz’ first
road-going racer. Based on the German manufacturer’s Grand Prix cars, the 300SL
was built on a light weight but stiff tubular steel frame with high sills that
necessitated the adoption of its signature Gullwing doors and tilting steering
wheel to access its minimalist cabin. Low, wide, and with a long hood and
elegantly rounded lines, the 300SL was classy and curvaceous, if not practical,
but delivered then excellent 0.39CD aerodynamics.

The world’s first
production car with direct fuel injection, the 300SL’s mechanical fuel system
was problematic in terms of engine lubrication, but nevertheless allowed its
3-liter straight 6-cylinder engine to produce 218HP at 5,800rpm and 275Nm
torque at 4,600rpm. Driving the rear wheels through a 4-speed manual gearbox,
the 300SL hustled its light 1,293kg mass through zero to 100km/h in 8.8
seconds. Meanwhile, when equipped with an optional 3.25:1 axle ratio, it was
capable of 260km/h, which made it the world’s then fastest production car.
With engine slanted
for better weighting and a dry sump lubrication system to ensure oil
circulation through hard-driven corners, the 300SL meanwhile rode on double
wishbone front and swing axles, rear suspension, and featured drum brakes,
front and rear. A thoroughly capable road racer, the 300SL’s suspension design
and its propensity for sudden mid-corner camber changes however lent it a
reputation for being a handful to drive effectively and safely at speed, and
requiring skill to eke out its full handling and performance potential.
