The development phase delivered some important findings for integration of the electric components into the vehicle, which could be housed within the existing constructed space without impairing the car’s everyday capabilities.
That applies both to the integration of the electric motors and power electronics, as well as to the battery. The latter, developed in house at Porsche and based on lithium iron phosphate cells, is fixed to the chassis structure in the same place as the internal combustion engine on the conventional Boxster S. This solution not only provides excellent protection for the battery in the event of an accident, but also offers the best conditions for preserving the base vehicle’s good handling qualities. In addition, the vehicles were equipped with acoustic generators in order to test the possibilities and acceptance of generating driving sounds.
Using comprehensive measuring equipment in the vehicles, all relevant parameters are being recorded and evaluated in the field test. This enables energy flows, energy consumption, efficiency and user behaviour to be analysed.
Based on over 23,000 kilometres driven in the field test, results and verdicts from approx. 200 drivers are available so far. The project goals in the areas of performance, range and energy consumption have been confirmed and the vehicles were in total judged very positively. In addition, over the course of comprehensive driving trials, valuable findings in relation to energy recovery, operating and display concepts, noise generation, charging and usage profiles were also gained.
