With the Audi e-tron FE05 Audi meticulously prepared for the new technical and strategic challenges. This particularly applies to the centerpiece of the Audi e-tron FE05: the powertrain. It consists of the motor, inverter, transmission, parts of the rear suspension and the related software. Whereas the rest of the car is identical for all teams, the manufacturers demonstrate their technical expertise in the powertrain. In season four of the electric racing series, which in New York City in mid-July culminated in Audi Sport ABT Schaeffler’s title win, the Audi e-tron FE04 was very often the most efficient car. The successor is the evolution of this success model.
In Formula E season five, the motor’s maximum power output in qualifying is limited to 250 kW (340 hp). In the races, power output is restricted to 200 kW (272 hp). The so-called activation zones are a new feature: When the driver passes through this zone on the track, the output of his car increases to 225 kW (306 hp) for a short period of time. Formula E fans are able to again support their favorite drivers by casting an online vote: The “FanBoost” provides a short-term power boost up to 250 kW (340 hp).
All Formula E teams draw their electric power from an identical, 374-kilogram battery from McLaren. The lithium-ion battery is located between the driver’s seat and the powertrain, has a capacity of 52 kWh and is fully charged within 45 minutes. The brake-by-wire system is an all-new function for season five. Brake actuation and transmission of brake force to the rear axle are completely isolated from each other and electronically controlled. As a result, brake force distribution is always optimally adjusted and recuperation even more efficient.
Like in Formula One, the driver sits in a carbon fiber monocoque that has been developed according to FIA safety standards. CFRP crash structures at the front, rear and the sides ensure maximum safety. Plus – analogous to Formula One – the cars are equipped with a Halo system above the cockpit that provides additional protection to the driver’s head. The minimum weight of a Formula E race car is 900 kilograms (including the driver). From 0 to 100 km/h the electric racing car accelerates in 3.1 seconds. Its top speed is about 240 km/h.
Particularly conspicuous is the fact that the new generation of the Audi e-tron FE05 does not have a rear wing – which is unique in motorsport. Instead, the large diffusor at the race car’s rear generates downforce. “Batmobile,” “Star Wars” and “space ship” were some of the expressions fans and media used in comments about the car’s futuristic look following initial tests. “Driving between other cars on track makes me feel as if I were in a science fiction movie,” says Daniel Abt. “Compared to its predecessor, the new model features a clearly more aggressive design.”
