Nicknamed after former head of vehicle development and creator of the 300 SLR, engineer Rudolf Uhlenhaut, the Uhlenhaut Coupé was built in 1955 based on the open top SLR racers famous for the Mille Miglia victory of Stirling Moss and Denis Jenkinson.
Equipped with a set of less than effective silencers to allow it to be road legal, Uhlenhaut famously used the 300 SLR Coupé as his everyday car, commuting to Stuttgart flat out while testing for a possible (but later cancelled) 1956 race season. Good man.
Just two Coupés were built using the same 3.0-litre, straight eight-cylinder engine with 310 horsepower. Combined with a total weight of 2,462 pounds, the 300 SLR Coupé was the fastest closed roof vehicle of its time, achieving its maximum speed of around 178 mph on its Autobahn runs.
Until you manage to convince Mercedes-Benz to sell you one, put it on your desktop so you don't forget about the challenge. Because racecar!
