It’s a hard struggle – even if it’s only thousandths we aim for. For 100 years Mercedes-Benz has been working to produce perfectly aerodynamic bodies for its cars. The CLA now crowns this effort with success: with a record Cd value of 0.23 and a drag area Cd x A of 0.51 m² it is aerodynamics champion within the Mercedes-Benz model range and among all production vehicles. This top figure is bettered only by the CLA 180 BlueEFFICIENCY Edition with a Cd figure of 0.22. With its drag area of only 0.49 m² it crosses a magical line and goes into the record books: as the most streamlined production car in the world.
Though the figures differ only minimally, the effects are tremendous: the smaller a vehicle's wind resistance, the lower its fuel consumption will be. So every thousandth of the Cd figure influences the vehicle’s efficiency.
