Aerodynamics are an necessary consideration in trendy EVs. Reducing aerodynamic drag improves effectivity, permitting for extra vary from a given battery-pack measurement.
But it surely bears emphasis: That is removed from a brand new obsession.
A brand new exhibit curated by Audi in Germany highlights an earlier period of aerodynamic experimentation. Within the Nineteen Thirties, engineers on the German automaker’s predecessor firms developed wild new physique shapes to assist scale back drag in combustion-engined automobiles.

Efficiency was as a lot a motivating issue as effectivity. Auto Union—one of many automakers later merged into the fashionable incarnation of Audi—utilized streamlined bodywork to its Sort C race automotive in 1937, permitting it to achieve a high velocity of 249 mph in a single speed-record run.
Related rules have been additionally utilized to a road-car kind issue with the Audi Sort C Jaray. It wasn’t simply German producers, both—the Chrysler Airflow debuted in 1934 with wind-tunnel-tested styling. However within the case of each the Sort C Jaray and the Airflow, aerodynamic designs have been simply too far out of step with buyer tastes within the prewar years. This was lengthy earlier than gasoline mileage grew to become a priority, so effectivity wasn’t a lot of a promoting level.
Right now, although, EVs have made aerodynamics a promoting level. The Lucid Air is proudly proclaimed by its producer to be the most aerodynamically environment friendly luxurious automotive, whereas Nio claims its EC7 is the most aerodynamic SUV on this planet.

The solar-assisted Lightyear 0 claimed the title of most aerodynamic manufacturing automotive total—with a coefficient of drag (Cd) or 0.175—however just a few models have been constructed. A current idea automotive from Chinese language automaker Chery claims a 0.168 Cd because of a physique form impressed by tuna, but it surely hasn’t been confirmed for manufacturing.
Electrical automobiles themselves as soon as gave internal-combustion automobiles (in addition to steam automobiles) competitors for auto-industry dominance earlier than fading away. And it bears some questions: Had EVs remained the dominant expertise a century in the past, would there have been extra of an emphasis on aerodynamics in current a long time? And what would the form of in the present day’s automobiles be if electrical motors, relatively than internal-combustion engines, had been the dominant type of propulsion via the twentieth century?
What if aero had by no means gone out of style? Depart your ideas under.
