A late-summer day in Neuburg an der Donau. Parked in front of the building of Audi’s Competence Center Motorsport is a production-based RS e-tron GT, surrounded by four men. Audi Sport ABT Schaeffler’s Formula E driver and champion of the 2016/17 season Lucas di Grassi is engaged in a discussion with three e-tron GT developers: Dennis Schmitz from Audi, Jaan-Mattes Reiling from Audi Sport GmbH and Christian Schröder from development partner PSW, an Audi subsidiary. Lucas di Grassi is a pro all the way – both at the wheel and off the race track. The native Brazilian, now living in Monaco, has been driving for Audi since 2012. In 2014, he won the inaugural race of the then newly launched Formula E, followed three years later by the title win with Audi Sport ABT Schaeffler. On 32 occasions, di Grassi stood on the podium for Audi in the past six years, which makes him the most successful driver in the electric racing series. Powerful performance also distinguishes the RS e-tron GT prototype. It is a superior Gran Turismo, with exceptional road performance in the RS version. The RS e-tron GT prototype is an example of the brand’s premium mobility and meets customers’ demands for high performance. Its dynamics, precision and high efficiency make it a pioneer with a strong character that shapes the future of the brand. The professional racer’s thinking goes far beyond motorsport, too. Lucas di Grassi is an international UN ambassador for clean air, so technological innovation and sustainable climate protection are a natural pairing in his book. Needless to say, the technology enthusiast from Monaco has a strong interest in Audi’s next electric car project, the e-tron GT. In Neuburg, he has the opportunity to drive the fully electric Gran Turismo as an RS model on the test track. For its developers Schmitz, Reiling and Schröder, it marks the moment of truth: in the driver’s judgment, will the production-based RS e-tron GT achieve the objectives they pursued? Dennis Schmitz: Well, Lucas, what do you say after the first five laps? Lucas di Grassi: The car is fun! Obviously, such a Gran Turismo is totally different to a race car. Even so, there are plenty of parallels, especially the powerful acceleration which, just like in our case, is fully available for a long time. From zero to a hundred kilometers per hour in clearly less than four seconds, and even continuing on the fifth lap – how did you do that? Christian Schröder: As you know, you need powerful thermal management for high and reproducible output. In the e-tron GT, we have two coolant circuits for the technical components operating on different temperature levels. The cooler one controls the temperature of the high-voltage battery and the warmer one serves the electric motors and power electronics. Plus, there’s a cold circuit and a heating circuit for the interior, which I suppose your race car doesn’t have. Schmitz: We can flexibly interconnect these four circuits via valves, for instance, as a highly efficient heat pump for the interior. However, the cooling of the high-voltage components under high loads and the cooling of the battery during fast DC charging processes are, no doubt, the most challenging requirements. After all, we reach output levels around 270 kW here that generate quite a bit of heat. Di Grassi: That’s pretty sophisticated! With so much high tech, the e-tron GT in terms of cooling is even more innovative than my Formula E race car. Obviously, temperatures in Formula E are even more extreme. That’s why we actively cool the battery down below the outside temperature during the charging process using dry ice. In this way, we gain more latitude with the system temperature in the race, because that’s when we heavily stress the powertrain by constantly changing between flat-out driving and recuperation. Obviously, this heats up the battery and costs energy. The more extreme the conditions, the more I have to pay attention to efficiency and management of my energy supply so that I’ll still have enough power left on the final laps.
