RUF Testing Three Incarnations of Electric Porsche 911

The tuning world has gone mad! RUF is electrifying Porsches! The German tuner is folowing the carmaker’s eco pathway, as it is currently planing to introduce a complex Porsche EV test program, which will include ten vehicles with three different configurations.

All three Frankelectricnsteins are based on the 997 Carrera, but come with different approaches: the first uses a single motor, while the second is powered by two motors, each with its own gearbox. The same twin motor principle is used by the third, but this comes with torque vectoring.

Here are the tech details of the vehicles:

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 analysis 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 the test vehicles will be fitted with on-board data logging system. You’ll get to meet at least one of them at the upcoming Geneva Auto Show.

autoevolution will be attending the 2011 Geneva Motor Show, so stay tuned for some real up close and personal shots of the vehicles, as well as for first-hand details of the motorized contraptions presented at the event.
