The eRuf Model A is a late-2000s all-electric concept sports car built by German automobile manufacturer Ruf Automobile. The car was powered by a UQM Technologies propulsion system (a UQM PowerPhase 150). The car has a top speed of 225 km/h (140 mph) and was capable of producing 150 kW (204 PS; 201 hp) of power and 479 lb⋅ft (649 N⋅m) of torque. Estimated range per charge was 250–320 km (155–199 mi), depending on performance level, using iron-phosphate, lithium-ion batteries built by Axeon plc of Great Britain. During coasting the engine works as a generator producing electricity to charge the batteries.
If a production car were to be built, it would be able to use a clutchless one- or two-speed transmission with no reverse gear as the electric motor can spin forward or in reverse. Ruf engaged Calmotors 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.
Ruf announced that it hoped to begin production of the eRuf in the fall of 2009. This did not happen, and at the 2009 Geneva Motor Show, Ruf announced a new model, the eRUF Greenster, with limited production planned to commence at the end of 2010.
