At Autovolt we’re big fans of electrified classic cars. Following our story about the Volkswagen Beetle in issue 15, Nov-Dec 2016, we were offered a glimpse at what can be achieved when electrifying something iconic. The Beetle and classic Campervan may be obvious examples, but the list doesn’t stop there. Kreisel Electric has completely converted a classic Porsche 910 into an electric supercar, named the Kreisel EVEX 910e. Gone is the loud Le Mans soundtrack and in is the powerful electric motor that propels the car from 0-62mph in just 2.5 seconds, onwards to a top speed of more than 300km/h (186 mph). The price for this retro-modern supercar? A cool one million euros. Best of all, it’s road legal, unlike the original. The vehicle is available as a limited edition only, in cooperation with EVEX Fahrzeugbau GmbH.
The original Porsche 910 sports car was fitted with a 2-litre flat-6-engine. Driven by German race driving duo, Rolf Stommelen and Jochen Neerpasch, the car achieved sixth place overall at the World Sportscar Championship in 1967 at Le Mans. Only 35 examples of the 910 were produced and used exclusively at circuit races and hill climbs. Due to its prestige, racing heritage and rarity, original examples fetch stratospheric price tags and tend to move between collectors. The vehicle manufacturer EVEX started to rebuild this type of vehicle in the 1970s – under the name, EVEX Porsche 910. After just four classic recreation supercars had been manufactured, production halted – until now.
After converting a Mercedes G-Class, which Kreisel presented together with Arnold Schwarzenegger in January, the Kreisel brothers and their team have once again shown 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 in August 2016. To enable the breathtaking acceleration and maximum speed, Kreisel developed an automated 2-speed transmission with a gear 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 are also offering their transmission as a standalone product, available to other electric car makers to take advantage of.
The high-performance (lithium-ion) battery pack, with 53 kilowatt-hour capacity, which is installed in the Kreisel EVEX 910e, weighs 1,100 kilograms and enables a realistic range of 350 kilometres (217 miles). To accommodate the battery system as well as the powertrain in the rear, the frame of the original vehicle has been slightly modified. Besides that the air-cooling of the historical vehicle was replaced by a cooling system which Kreisel developed for the high-performance drivetrain.
Energy management: Sports car now features home storage
The battery can be charged rapidly at up to 100 kilowatts and has an intelligent energy management that can accept photovoltaic solar charge. By means of bi-directional charging the sports car can also be used as a home storage battery (V2H) and temporarily stores regenerative energy to dispense it back to a home, if required.
EVEX Fahrzeugbau GmbH is a vehicle manufacturer, specialising in historical cars from the 1970s. In addition to the electrified edition, the company is also producing a small run of petrol powered EVEX Porsche 910. The electrified super sports car will have its world premiere at the prestigio classic car fair, TECHNO-CLASSICA Essen, at the booth of EVEX (KA-09).
About Kreisel Electric
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, buses 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.
