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 the 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.
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 a 2-speed automated 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 battery can be charged rapidly with up to 100 kilowatts DC 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 electrified super sports car will have its world premiere at the most important classic car fair the TECHNO-CLASSICA Essen, at the booth of EVEX (KA-09).
