Almost 50 years after this vehicle type participated in the 24 Hours of Le Mans, the electromobility specialist Kreisel Electric has completely converted a Porsche 910, turning it into an electrified supercar. The Kreisel EVEX 910e handles speeds above 300 kilometres per hour, accelerates from 0 to 100 km/h in 2.5 seconds and - in contrast to the historical original by Porsche - is licensed for use on public roads. In cooperation with the EVEX Fahrzeugbau GmbH this vehicle is available as a limited edition. The price for the first purchasable electric car by Kreisel: one million Euros.
With the Porsche 910 sports car fitted with a 2-litre flat-6-engine, the two German race drivers Rolf Stommelen and Jochen Neerpasch achieved the sixth place in the overall ranking at the World Sportscar Championship 1967 in Le Mans. The vehicle was produced only 35 times and utilized exclusively for circuit races and hill climbs. Nevertheless - or exactly for this reason - the collector value of the original vehicles is enormous. The vehicle manufacturer EVEX started to rebuild this type of vehicle in the 1970s - as EVEX Porsche 910. After just four classic supercars had been manufactured the production was discontinued - up to the present day.
After converting a Mercedes G-Class, which Kreisel presented together with Arnold Schwarzenegger in January, the Kreisel brothers and their team show once again that the future belongs to electronic mobility and that there are scarcely any limits. "With the first purchasable electronic Kreisel-car our company is entering into a new phase", says Markus Kreisel, Managing Director at Kreisel Electric. "The Kreisel EVEX 910e combines the feeling of sitting in a fascinating classic car with the incredible dynamics of a 490 electric hp motor and a torque of 770 Newton meters - all entirely without emissions and thus without a guilty conscience."
New: 2-speed transmission for electric mobility
Kreisel and EVEX started working on the conversion of the vehicle last year in August. To enable the breathtaking acceleration and the maximum speed, Kreisel developed an automated 2-speed transmission with a gear transmission ratio of 8.16 (in 1st gear) and 4.67 (in 2nd gear), as well as self-locking differential and integrated, electric oil pump to ensure lubrication and cooling. The Austrians also offer the transmission as a standalone product.
The high-performance (lithium-ion) battery pack, with a capacity of 53 kilowatt-hours, which is installed in the Kreisel EVEX 910e, weights 1.100 kilograms and enables a realistic range of 350 kilometres. To accommodate the battery system as well as the powertrain in the rear, the frame of the original vehicle was slightly modified. Besides that the air-cooling of the historical vehicle was replaced by a cooling system which Kreisel developed for the high-performance drive.
Energy management: Sports car now features home storage
The storage system can be charged rapidly with up to 100 kilowatts and even enables an intelligent energy management in combination with a photovoltaic installation, for instance on a single-family house: by means of bi-directional charging the sports car can even be used as a home storage and temporarily stores regenerative energy to dispense it back to the house, if required.
The EVEX Fahrzeugbau GmbH is a vehicle manufacturer, specialized on historical cars from the 1970s. In addition to the electrified edition, the company also puts a small batch of the EVEX Porsche 910 on the market, a replica of the sports car with combustion engine.
The passion for speed and electronic mobility motivates the entrepreneurial actions of the three Kreisel brothers from Freistadt, Upper Austria. Driven by the vision of integrating the electric drive in all areas of mobility, Philipp, Johann jun. and Markus have developed the lightest weight and most efficient battery solutions for e-mobility. These were put into use in numerous applications ever since 2014.
The range of applications put into practise, together with various partners, include e-karts, electric bikes and scooters, as well as cars, busses and commercial vehicles up to ships and airplanes. In collaboration with industry partners Kreisel implements complex projects containing the development of power trains, charging technology and software. The stationary storage battery MAVERO was presented by the company in summer 2016, followed by the Kreisel Power Charger, an innovative fast-charging station in January 2017.
Due to the special assembling and the innovative thermal management, mobile and stationary power storages profit from the high-performance battery technology developed by Kreisel. To meet the global demand for battery packs, Kreisel Electric is currently erecting its first factory for large-scale production in Rainbach, Austria. At a range of other locations, the storage battery packs will be produced under licence by partners who are car manufacturers, fleet operators, and cab or transport companies.
