Red Bull using electric engine for pitstop practice 21 August, 2014 Red Bull mechanics (File Photo) Red Bull was experimenting with an all-electric Formula 1 car at Spa on Wednesday, according to Auto Motor und Sport and Autosprint who reported that the reigning world champions’ electric prototype was in fact a 2013 RB9 sporting a 2014 nose. But the real novelty was its propulsion – an all-electric motor to power the car in and out of the pitlane ‘box’ as the mechanics practiced pit stops. After a practice stop, Autosprint correspondent Alberto Antonini reveals, the mechanic in the cockpit pushed a button, a reverse warning ‘beeps’, and the car lurched backwards to be ready for another stop. “This is the new Formula E,” Auto Motor und Sport correspondent Tobias Gruner quoted a Red Bull mechanic as joking. He added that among the fascinated observers in the Spa-Francorchamps pitlane on Wednesday was none other than FIA technical delegate Jo Bauer.
