The sixth generation Opel Corsa not only has more driver assistance systems than most of its rivals but also has superior aerodynamics.
The new aerodynamic design result is a drag coefficient of only 0.29 – an excellent value for a car of this size – and compared to its predecessor a further reduced frontal area of only 2.13m2, making the new Corsa one of the most aerodynamic cars in its class. Also, the new generation of Opel’s bestseller already meets the future Euro 6d emissions standard.
“Aerodynamics is just one area where Opel is increasing the efficiency of its automobiles”, said Managing Director Engineering, Christian Müller. “Advanced petrol and diesel powertrains and state-of-the-art electrification are the other tools we are using to significantly cut fuel consumption and CO2emissions. All these technologies are fully embraced by our new Corsa, which will also be available for the first time as the all-electric Corsa-e.”
Due to the challenges posed by CO2reduction, perfect aerodynamics are gaining great importance in the automotive industry as well as among customers. Low drag means that less energy is needed to move the car, which in turn results in reduced fuel consumption and lower emissions.
For example, a ten percent cut in drag results in a fuel consumption reduction of around two percent in the New European Driving Cycle (NEDC), or up to five percent when driving at 130 km/h. Opel’s engineers achieved this leading drag factor of 0.29 Cdby paying attention to every detail that helps improve the new Corsa’s aerodynamics. The new Corsa also features a spoiler at the rear edge of the roof, which improves the airflow and reduces the turbulence that causes drag. The spoiler cuts aerodynamic lift on the rear axle too, which further improves the new Corsa’s straight-line stability, especially at the higher speeds typical of the German autobahn.
The sixth generation of Opel’s bestselling small car is not the first aerodynamically optimised Corsa to make its debut at the IAA. At the 1995 Frankfurt show, Opel surprised the industry with an engineering study based on the Corsa for a so-called “three-litre car”, i.e. it was designed to return an average fuel consumption of less than 3.5 litres per 100 kilometres. Twenty-four years later a series production car has achieved the same excellent result: the new Opel Corsa.
