In the automotive industry, we measure aerodynamics thanks to the car Cx, which represents penetration coefficient in the air. The better this indicator is, the lower the car’s resistance to the particles that make up the air. In addition, his Maximum speed it directly depends on it.

In addition, even more contributes fuel consumption car model and, therefore, its autonomy, which is especially interesting for electric cars The latter also benefits, from the point of view of the drag coefficient, due to the absence of visible engines in the front, which increase the frontal surface and allow to minimize the intake of cooling air.

The Skoda Enyaq Coupe iV recently released and testing herealready displays a Cd 0.234. For comparison, the world champion of 1989Vauxhall Calibrahas Cd 0.26 !

10. Skoda Enyaq Coupe iV

It may be hard to believe, but even an SUV managed to make it into the top ten Cx. The design of the coupe, the closed radiator grill, as well as the well-thought-out aerodynamic sophistication allow the Skoda Enyaq Coupé iV to get Cd 0.234. Despite the power of the electric units of 220 kW (299 hp), the coupe can travel 520 kilometers, almost as much as the regular Enyaq, which is 25 kW (34 hp) less.

9. BMW 520d Efficient Dynamics Edition

Ten years ago, BMW already knew that aerodynamics could be a good way to reduce fuel consumption. Slightly lowered, almost closed discs, higher transmission ratios, and a centrifugal swingarm that provides a smooth roll at 50 km/h in sixth gear make this 520d a long-distance champion. The two-liter diesel engine develops 184 hp. (135 kW) and consumes only 4.5 liters of fuel per 100 kilometers. AND Cx is 0.22.

8. Porsche Taycan

The Porsche Taycan’s low air penetration coefficient of 0.22, which is two hundredths better than the Audi e-tron GT, primarily allows it to reach a respectable top speed of 260 km/h. In addition to the aerodynamic design and maximum speed, the sedan also has a wide selection of engines and bodywork. Engine power varies from 300 to 560 kW (408-761 hp), distributed between rear and all-wheel drive. The Taycan can travel up to 504 kilometers according to the WLTP standard.

7. Ioniq 6

You don’t need to be an aerodynamics expert to understand the design of the Ioniq 6. Especially when comparing the Ioniq 5, its clumsy sibling, to the Ioniq 6. The teardrop shape is very pronounced. Love it or hate it! However, the result of work in the wind tunnel is impressive: the coefficient of air resistance is 0.21, which will raise the Korean to seventh place in our ranking. This size is especially impressive when looking at the rear, where there are not one, but two spoilers that help evacuate the wind. Camera-based exterior mirrors and flush door handles are other details that make a splash. Power can reach 239 kW (325 hp) for a top speed of 190 km/h. Autonomy can reach 614 kilometers.

6. Bright air

Lucid Air and its elegant design promise up to 900 kilometers on a single charge. Like the Ioniq 6, the Air body has an air permeability coefficient 0.21 – even with conventional exterior mirrors. The total power of the electric motors is 828 kW (1111 hp!), which accelerates the luxury sedan to 100 km/h in less than three seconds. More powerful versions should appear, easily exceeding these values ​​and even reaching a top speed of more than 320 km/h.

5. Nio ET7

The Chinese contender Nio ET7 scores points not only with air permeability 0.208, but also with a range of up to 1,000 kilometers according to the more generous NEDC standard. And instead of staying connected to the grid for minutes or even hours with a battery that drains over time, you can replace the battery with a new one in five minutes at a specially designed replacement station. There are also two electric motors on board at all times, which provide a combined power of 480 kW (650 hp), which allows the sedan to accelerate to 100 km/h in 3.8 seconds. The limiter allows you to accelerate on the track up to 200 km/h.

4. Tesla Model S

Very close to the podium was the Tesla Model S. With the coefficient of air resistance 0.208 in fact, the benchmark of the segment is on the same level as the Nio ET7. In fact, only the latest facelift in 2021 achieves such a drag coefficient, while the American sedan in its first version was stuck at 0.24. With the Plaid, Tesla seriously competes with supercars, not only thanks to its 0-100 km/h acceleration time of 2.1 seconds, but also with its top speed of 320 km/h. Autonomy of 663 kilometers is also a strong argument.

3. Mercedes EQS

For several years, Mercedes has been one of the champions of aerodynamics, as confirmed by the aerodynamic CLA or E-Class sedans. The most aerodynamic production model of Stuttgart is called Mercedes EQS and boasts an equally impressive drag coefficient 0.202. In 2021, this value was even enough to set a world record. Tremendous wind resistance is also necessary for this 2.8-ton luxury liner to travel long distances. The latter demonstrates 782 kilometers of autonomy. And in the AMG version with a power of 560 kW (761 hp), the maximum speed is 250 km/h.

2. Volkswagen XL1

Since only 250 units were produced in 2013, we cannot talk about mass production. And with Cd is only 0.189, this XL1 has long been classified as a UFO on wheels. In addition to diesel consumption of 1.8 liters, the XL1 also impresses with its unique design, which does not at all correspond to the strict appearance of modern models from Volkswagen. In a coupe weighing only 795 kilograms, external mirrors with a camera were already used, which was not a very common phenomenon for that time. The maximum speed of 160 km/h is achieved thanks to the unit with a capacity of 69 hp. (51 kW), which accelerates from 0 to 100 km/h in 12.7 seconds.

1. Light year 0

With 956 examples produced, the Lightyear 0 won’t necessarily count as a production model either. Technical data make the Dutch sedan the absolute number 1 when it comes to aerodynamics. With a flat arch, closed rear wheels and a sleek rear, the body looks like it’s straight out of a designer’s manual. The result gives a Cx, which drops to 0.175 ! Autonomy of 625 kilometers, charged through solar panels on the surfaces of the body, without the need to connect the car to an outlet. The price is 250,000 euros!
