Team Profile:-
e-gnition Hamburg’s 2013 car, the egn13, is a consequent advancement of the egn12. The technical spotlight was set on a reliable racecar. A modular electronic information management system was developed, which is mainly used for torque vectoring and telematics. With an easily removable accumulator container and the new ergonomics we not only help our drivers during the race, but the crew in the box as well. To reduce the racecar’s weight, we increased the use of fibre composites, a highlight being the accumulator box structure.
The egn13 is powered by two Emrax motors with a peak power of 60kW each. They are powered by Bamocar controllers which we placed into our self-developed, weight optimized housing. To further reduce weight, we are cooling all components by air. To enhance the on-track agility we advanced our torque vectoring software. With the torque vectoring and our new suspension the driver feels a more direct car which handles very controlled. The crew is able to read the telemetric data in real time during the race and due to new server technologies we are also able to allow our supporters and fans to take a real time look at the cars performance data from home.
