The eRuf Model A is an all-electric sports car made by German automobile manufacturer Ruf Automobile. The car is powered by a UQM Technologies[3] propulsion system (a UQM PowerPhase 150). The car has a top speed of 225 kilometers per hour (140 mph)[4] and it’s capable of making 150 kW (204 PS; 201 hp) and 479 lb·ft (649 N·m) of torque .[1] Estimated range per charge is 250 kilometers to 320 kilometers, depending on performance level, using iron-phosphate, lithium-ion batteries built by Axeon plc of Great Britain.[5] The power and torque produced by the 3-phase motor can be used to recover almost as much power as it can put out.[2] During coasting the engine works as a generator producing electricity to charge the batteries.[2]
Ruf has ripped the combustion engine out of a Porsche 911 and slotted in an electric motor.[6]
A probable production car would use a clutchless one- or two-speed transmission with no reverse gear as the electric motor can spin forward or in reverse.[1] Ruf engaged Calmotors[7] in Camarillo, California, specialized in the implementation of hybrid electric and electric only powertrain design, to combine the latest generation of lithium-ion batteries with its motor.[2]
Ruf hopes to begin production of the eRuf in the fall of 2009.[1]
The prototype was unveiled in 2009 Geneva Motor Show.[8]
