The Mercedes Simplex 60 hp was an automobile manufactured by Daimler Motoren Gesellschaft in 1903 and 1904.
Its predecessor was the Mercedes 35hp which had been the fastest production car in the world.
[citation needed] Unlike the 35 hp though, this wasn't a racing car and became Mercedes' top of the range model.
It had a low pressed steel chassis and a cast-alloy 9.3L engine, giving a top speed of 68 mph (109 km/h).
On 11/12 July 1904 Harry Harkness set the first record for the Mount Washington Hillclimb Auto Race with a time of 24 minutes 37.6 seconds.
