Mercedes Claims SUV Shape Will Change In Electric Era For Better Efficiency
The roof needs to be more sloped towards the rear for improved airflow.
Aside from being considerably smaller and therefore lighter, at 1,750 kilograms (3,858 pounds), the all-electric concept is also much sleeker. It has a drag coefficient of only 0.17 whereas the EQS has a Cd of 0.20 shared with the smaller EQE. That might not seem a huge difference, but the three-pointed star claims a reduction of only 0.01 adds approximately 2.5 percent to the range. It's not possible to make blocky SUVs as efficient, but Mercedes is working on flowy shapes.
Schäfer mentioned that even though the "customer loves SUVs, no doubt," as they are now, the shape will change in the years ahead to maximize range. However, Daimler chief designer Gordon Wagener admitted SUVs will never be as efficient as these lower cars, hence why the Vision EQXX was conceived with a "low, sedan-ish" profile.
