Aerodynamics are an vital consideration in trendy EVs. Reducing aerodynamic drag improves effectivity, permitting for extra vary from a given battery-pack dimension.
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 cut 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 trendy incarnation of Audi—utilized streamlined bodywork to its Sort C race automobile in 1937, permitting it to achieve a high velocity of 249 mph in a single speed-record run.
Related ideas had 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 had been simply too far out of step with buyer tastes within the prewar years. This was lengthy earlier than fuel mileage turned 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 probably the most aerodynamically environment friendly luxurious automobile, whereas Nio claims its EC7 is probably the most aerodynamic SUV on the planet.

The solar-assisted Lightyear 0 claimed the title of most aerodynamic manufacturing automobile general—with a coefficient of drag (Cd) or 0.175—however only some items had been constructed. A latest idea automobile 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 know-how a century in the past, would there have been extra of an emphasis on aerodynamics in latest a long time? And what would the form of at present’s automobiles be if electrical motors, moderately than internal-combustion engines, had been the dominant type of propulsion by means of the twentieth century?
What if aero had by no means gone out of vogue? Depart your ideas under.
