Audi’s Aerodynamic Innovations: The Key to the Impressive Range of the New A6 e-tron
Battling wind resistance is a constant challenge for automakers, and Audi has been at the forefront of reducing aerodynamic drag on their cars. The latest achievement in this area is the new Audi A6 e-tron, which boasts an impressive drag coefficient of just 0.24. While it may not be the leader in this regard, with Tesla Model S, Hyundai Ioniq 6, and Lucid Air claiming better figures, Audi’s journey to 0.24 has been paved with historic cars and groundbreaking innovations.
The Legacy of Audi’s Aerodynamic Pursuit
Audi’s commitment to aerodynamics dates back to the 1930s when they began testing and refining the science. One notable example is the 1937 Auto Union Type C, which featured a supercharged V16 engine and a body design that looked shrink-wrapped onto the chassis. This pioneering vehicle achieved a top speed of 250 mph, a remarkable feat even by today’s standards.
In 1982, Audi set a record for the most aerodynamic production car with the Audi 100. This model incorporated several small touches that minimized wind resistance, such as hidden wipers, aerodynamic mirrors, and a streamlined greenhouse. These innovations made a significant impact on reducing drag and improving overall efficiency.
Audi A6 e-tron: A Culmination of Aerodynamic Expertise
The new Audi A6 e-tron leverages Audi’s decades of aerodynamic research and development. The front bumper features small gaps that create a uniform curtain of air, reducing drag on the front wheels. Additionally, the camera side mirrors, although not available in the USA, further slice through the wind and provide an additional range of seven kilometers (4.3 miles) compared to traditional mirrors.
The undercarriage of the A6 e-tron is completely sealed off to prevent unnecessary drag. However, there are clever design elements that optimize airflow. Certain areas channel air to cool the battery, while an active stall at the rear reduces turbulence. These innovations contribute to the A6 e-tron’s impressive range of 447 miles (720 km) after WLTP testing.
Conclusion
Audi’s relentless pursuit of aerodynamic excellence has resulted in the remarkable range and efficiency of the new A6 e-tron. By drawing inspiration from historic cars and implementing cutting-edge innovations, Audi continues to push the boundaries of automotive aerodynamics. The A6 e-tron stands as a testament to Audi’s commitment to sustainable mobility without compromising performance.
