SSK (1928)

Regarded by many as the finest pre-war sportscar ever built, the SSK was actually designed by Ferdinand Porsche and was the ultimate evolution of the 'S' model line launched two years earlier.

The S was itself a lower chassis version of the ‘K’ series cars and used a supercharged 6.8-litre engine. In order to go Grand Prix racing Mercedes needed a smaller, lighter car so they chopped 19 inches out of the chassis to create the “Super Sport Kurz”, the last word being the German for short. Much lighter than its 2.5 ton predecessors the SSK was used to devastating effect by greats such as Rudolf Caracciola, winning numerous competition events including the 1930 Grand Prix, thanks to a 7.1-litre supercharged engine producing 225bhp. The final model actually produced 300bhp and had holes drilled in its chassis to lighten the car in an attempt to keep it competitive.

300SL 'Gullwing' (1954)

Loosely based on the successful 1952 competition car of the same name, the 300SL was available as a convertible or a coupe with those now legendary 'gullwing' doors. These were necessary because of the car’s tubular chassis which ran through where the lower half of the door would be on a standard car, making it exceptionally stiff for its day but making entry and exit a feat in gymnastics. It was also the first production car fitted with fuel injection.

The mechanical system from Bosch more than doubled the power of the three-litre straight six from 115bhp to 240bhp, making it more powerful than the original racer. Around 1400 were made, with the similar looking 190SL roadster outselling it by nearly eight to one until both were replaced in 1963 by the 230SL.

300SLR (1955)

Despite the name this bore no relation to either Gullwing or the earlier racecar. It was essentially the 1954 Mercedes W196 Grand Prix car, its straight-eight engine enlarged from 2.5 to three litres and covered with a two-seater roadster body. It was in this form that a 300SLR won what is perhaps still the most famous race victory of all time.

With a young British racing driver named Stirling Moss at the wheel, directed by co-driver Denis ‘Jenks’ Jenkinson, the 300SLR destroyed the opposition in the 1955 Mille Miglia, a non-stop 1000 mile race on public roads in Italy. Moss won the event at a scarcely credible average speed of 97.96mph. The 300SLR was withdrawn from competition when one crashed into spectators at Le Mans in 1955, killing 82 spectators. The shock of this horror stunned Mercedes, and it withdrew from racing, not to return until 1987.
