Quote: At the beginning of this month, Audi presented the concept car e-tron quattro concept at the IAA, an electric SUV offering 500 kilometres of range and intended to be launched in 2018. Due to the range that surpasses that of the Model X (maximum 413 kilometres), many media have quickly named the concept vehicle from Audi as “Tesla Killer”. Tesla Motors officially unveiled the Model X yesterday, and thereby announced further information, including the W the so-called flow resistance coefficient, also known as the cW value. This is 0.24 in the Model X and thus 20 percent lower than the next best SUV. Such values are not attainable with an SUV with internal combustion engine. Interestingly, Audi boasted at the presentation of its “Tesla Killer” that with a cW value of 0.25 a new best mark in the SUV segment has been set – that’s how it continues to be on the official company side. The main argument for many media that Audi’s concept car was to call a “Tesla Killer” was the range. However, one has to bear in mind that Audi is a German car manufacturer and thus the range of the vehicles is measured by means of the New European Driving Cycle (NEFZ). Tesla Motors, on the other hand, gives the range according to the values of the US Federal Office of the EPO. The values of the New European Driving Cycle (NEDC) are often not as practical as the EPA values. For example, according to NEDC, the Tesla Model S 85D has a range of 330 miles, while EPA indicates the range of 270 miles. This corresponds to a difference of over 22 percent. The Model X could therefore create values similar to Audi with a 95 kWh battery. Just recently, Elon Musk mentioned in a video interview with a Danish newspaper (the video was mid-wayed). unfortunately removed from Youtube), that he considers an improvement in the range of five to ten percent per year to be realistic. For this reason alone, it is clear that the designation “Tesla Killer” for a concept vehicle that appears in 2018 has been chosen very hastily.
