RUF Automobile GmbH is developing various electric-powered sports vehicles based on the Porsche 911 for the purpose of running field tests of electric vehicles in real life situations. The first ten eRUF vehicles, manufactured in cooperation with Siemens AG, will be presented in the first half of 2011. The project is supported by the German Federal Ministry of the Environment for whom the results of the field tests relating to different battery and power-train concepts are of particular interest. For this purpose, all vehicles are equipped with on-board data logging systems.
The following vehicle specifications are being manufactured for the purpose of the above mentioned field tests:
1. Single Motor Concept
– Base vehicle, Porsche 997 Carrera
– Electric motor (180 kW) and inverter from Siemens AG
– Porsche production gearbox used for speed reduction
– Lithium-ion batteries with an energy capacity of 29 kWh
– Integrated charger, DCDC-converter, plug, socket and charging cable
– interior heating
– Data recording unit for analysis and documentation of the charging/ discharging, journey and component data
– Driving range approximately 150 km, maximum speed about 220 km/h, acceleration from 0 to 100 km/h in about 7 seconds
2. Twin Motor Concept with 2-speed Gearbox
– Base vehicle, Porsche 997 Carrera
– Two transversely mounted Siemens synchronous electric motors (250 kW) with double inverters
– Automatic 2 speed gearbox, limited slip differential
– Liquid cooled and heated lithium ion battery with an energy capacity of 36,6 kWh
– Integrated charger, DCDC-converter, plug, socket and charging cable
– interior heating
– Data recording unit for ananlysis and documentation of the charging/ discharging, journey and component data
– Driving range approximately 200 km, maximum speed about 220 km/h, acceleration from 0 to 100 km/h in about 5 seconds
3. Twin Motor concept with Torque Vectoring
– Base vehicle, Porsche 997 Carrera
– Two transversely mounted Siemens synchronous electric motors (250 kW) with double inverters
– Two seperate angular bevel gearboxes for independent rear wheel drive
– Liquid cooled and heated lithium ion battery with an energy capacity of 36,6 kWh
– Charging via inverter, DCDC-converter, plug, socket and charging cable
– interior heating
– Data recording unit for analysis and documentation of the charging/discharging, journey and component data
– Driving range approximately 200 km, maximum speed about 180 km/h, acceleration from 0 to 100 km/h in about 5 seconds
All eRUF field test vehicles receive an individual technical approval certificate from the German inspection agency (TÜV).
