RUF Automobile

The famous Haldenhof Revival took place in Ludwigshafen, near the Lake Constance, from the7th to the 9th of October 2011. Our eRUF was also there, representing Windreich in the racing class of this traditional hill climb, and managed to create a lot of attention among the viewers because of it’s performance and achieving one of the best lap times. Windreich displayed it’s own mobile power plant to exhibit the whole chain of processes involved in electric mobility. This mobile charging station powered with wind can be raised up to ten meters, with a rotor measuring a total of four meters in diameter.

The date is the 10th of September and the sun is shining on 42 emission-free, alternately powered vehicles on the way from Mannheim to Pforzheim. Much like when Bertha Benz’s loud, rattling vehicle was travelling on the very same route back in 19th century like today, onlookers were surprised, but instead of being scared of what they saw, this time they were delighted by this astonishing sight.

Even State minister Silke Krebs herself was thrilled, and Baden-Wurttemberg’s Minister of Economy, Theresia Bauer was quite surprised by the performance of the vehicles. Afterwards she promised that will become a strong Focus of development politics.

Two powerful electric vehicles were part of the event, starting in representation of Windreich AG: An eRUF Coupé and an electrified Jaguar E-Type from 1961. The route started Saturday from Mannheim through Heidelberg and Bruchsal, until it reached Pforzheim. On Sunday, the convoy tracked back to Mannheim through the cities of Gondelsheim and Bruchsal. No incidents impeded the completion of the trip by the contestants.

This event marked the end of the Automobile Summer season of 2011 as well as the opening of the “Bertha Benz Memorial route”

The IAA 2011 will be open to the general public at the Frankfurt Trade Fair complex from the 15th until the 25th of September. For the first time in history the IAA will have a hall dedicated exclusively to “Electric Mobility”.

RUF Automobile GmbH will exhibit the electric eRUF at the Bayern Innovativ booth (hall 4.0, booth C23).

We look forward to your visit!

The e-miglia is a rallye only for electric vehicles. RUF Automobile GmbH took part with two eRUF automobiles.
The e-miglia 2011 led from Munich to St. Moritz, via Mittersill and Bolzano. Four daily stages through four countries in Central Europe had to be accomplished by the participants.
The two eRUF Coupés managed to go the complete route without any technical problems. However, the event managers had problems organising a proper battery charging system and this lead to difficulties and delays for the participants.
Overall, valuable experience could be gained.

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.

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
- 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
- Driving range approximately 200 km, maximum speed about 250 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
- 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).

RUF introduces the first SUV with electric powertrain

RUF Automobile GmbH, located in the small Bavarian town of Pfaffenhausen, the manufacturer of high performance automobiles, introduced the first electric sports car (eRUF) from Germany in October 2008.

During the Geneva Motor Show, in March 2009, RUF presented an evolution of the first eRUF.
The eRUF family continues to grow with the unveiling of the "Stormster", the very first electrically driven SUV based on the Porsche Cayenne.

The Stormster is driven by a Siemens electric motor, with 270 kW (367 HP) as in the eRUF sports car. The total weight is 2,670 kg which makes it capable of reaching 100 kph in only 10 seconds. The top speed is 150 kph, being able to reach a range of 200 km with one charge.

The lithium-ion accumulators are supplied by Li-Tec Battery GmbH. Li-Tec is the first manufacturer of lithium-ion battery cells in Europe, designed for the automobile industry using ceramic storage technology.

Hankook developed the winter tires for the all-wheel drive Stormster which is fitted to RUF classic 5-spoke lightweight wheels. Tires of size 295/30 R 22 allow the best possible road grip.

The Stormster will have its first public debut during the European Climate Change Conference in Copenhagen, (COP 15), Denmark from December 7th to 18th 2009.

On September 7th 2009, further turnouts for the future were posed in Halberstadt. The federal environment minister Sigmar Gabriel handed subsidies promise in the high of millions for the project "Harz.renewable Energy-mobility".
An economy plan that should make the regenerative energy usable for electric vehicles.
You could see the future at the factory premises of the Halberstadt works.
Cars as well as commercial vehicles that are powered by electric engines.
The minister also had the greatest pleasure test driving the eRUF.

RUF at the 1st International Fair for Electric Mobility from the 13th until the 15th of October 2009 at the New Munich Trade Fair Centre.

Fresh maritime air, picturesque dunes, sunny hours - nature is the real cultural asset of the North Sea Island Sylt. But there is also an automotive culture. From June 5th to 6th 2009 in the town of Keitum, RUF Automobile displayed its eRUF. Porsche automobiles are quite frequent in Sylt.
RUF has developed the eRUF, which is absolutely emission-free because of a powerful electric engine.
The eRUF is based on the latest Porsche 911. A three-phase engine makes for thrust. The electric engine has 270kW (367 HP) and up to 950Nm torque. The eRUF accelerates to 0-100 km/h in 5 sec. Maximum speed is an impressive 250 km/h.


The eRUF will go into production by mid-2010 and will have a dual engine, the innovative integral eDrive.

The electric avenue in Friedrichshafen at the lake Constance will take place between May 21st and 24th 2009.
New alternative drivetrains are in the limelight of the new expo for effective mobility. RUF will present its eRUF.

For enthusiasts of exclusive automobiles and luxury goods there was only one destination in April: Monte Carlo. From April 16th to 19th one of the most exciting events in the automobile industry took place in Monte Carlo: the "Top Marques Monaco". RUF not only presented the new Rt12S, but also the superlative CTR3 and the spectacular electric car eRUF.

At the international Motor Show in Geneva from March 5th to 15th 2009 RUF Automobile GmbH and Siemens Corporate Technology announce their cooperation for the eRUF. In the symbiosis between two leading companies - Siemens in the electrical industry and RUF in the automotive industry - the biggest possible synergies are used to expedite the future of electric mobility. The eRUF will be presented to the public at the RUF stand in hall 5. For more information please follow our link DOWNLOAD.
