In Formula E Schaeffler and Audi Sport are taking technologies to the limits Events in major cities Formula E delivers an emotive environment That s exactly why Schaeffler became involved in For mula E early on in order to use the know how gained on the race track for the development of electric pow ertrain systems in production In the Schaeffler 4ePerformance concept car the automotive supplier showcases the technolo gy that s already feasible today The all electric ve hicle transforms and multiplies technology from the ABT Schaeff ler FE01 Formula E car in a notchback se dan The Schaeffler 4ePerformance is powered by four Formula E traction motors They ve been adopted from the race car and were used in the full second Formu la E season In the Schaeffler 4ePerformance concept each motor is directly connected to a wheel via a spur gear with two transmissions per axle sharing the same housing The twin axle enables wheel selective distri bution of torque aka torque vectoring Powered by two traction batteries with a total capacity of 64 kWh the vehicle develops output of 880 kW equivalent to about 1 200 horsepower Formula 1 toys with the idea of electricity But back to the race track While many established racing series are struggling with declining popularity Formula E is booming The electrification of the power train is legitimizing top caliber motor racing again rea son enough for traditionalists to take a close look at electrification as well even in Formula 1 2009 was the year in which KERS hybrid technology was introduced into motorsport s top category The response though was not very encouraging too little influence on lap times and essentially way too heavy Many teams chose not to use the technology 2014 produced the revolu tion the new power unit an IC engine with two energy recuperation systems a turbocharger and an enormous battery The KERS of the new V8 engines now had twice the output of its predecessors 120 kilowatts about 160 horsepower Now that s something to write home about It s safe to assume that no changes will be made to this powertrain until 2020 but then Head of Mer cedes Motorsport Toto Wolff excludes the possibility of a return to conventional aspirated engines Formula 1 is the world s fastest lab we must be sure not to lose that Drawing even more power from the hybrid engines would have to be the objective To achieve it Wolff can even imagine some drastic actions If this should mean ELECTRIFYING EXCITEMENT outlo o k 91
