La Jamais Contente (French pronunciation: [la ʒamɛ kɔ̃tɑ̃t]; English: The Never Contented) was the first road vehicle to go over 100 kilometres per hour (62 mph). It was a Belgian electric vehicle with a light-alloy torpedo-shaped bodywork and batteries. The high position of the driver and the exposed chassis underneath spoiled much of the aerodynamics.[2] The light alloy, called partinium, is a mixture of aluminium, tungsten and magnesium.[3]

The land speed record was established on 29 April or 1 May 1899 at Achères, Yvelines near Paris, France. The vehicle had two Postel-Vinay 25 kW motors, each driving the rear axle via a chain, running at 200 V and drawing 124 A each,[1][4] for about 68 hp total, and was equipped with Michelin tires. The chassis was number 25.

Today, it is on display at the National Car and Tourism Museum in Compiègne.[5]
