The new 2022 Nissan Ariya EV is about more than just it’s striking looks — its aerodynamic design actually helps boost its eco-friendly efficiency and range.

Thanks to its sleek profile, the Nissan Ariya has achieved a drag coefficient of 0.297, making it the most aerodynamic crossover that Nissan has ever produced.

The Ariya was sculpted with exacting bodylines and intelligently placed air vents, all with the intention of helping drivers get more range out of every charge. When the Ariya was first revealed, Nissan estimated that it would deliver about 300 miles of driving range. But thanks to its refined design, Nissan engineers expect the Ariya to offer even more.

According to Nissan, engineers from around the world united at the Nissan Technical Centre Europe to work on the Ariya’s design. These experts tweaked the EV’s shape down to the microscopic level, adjusting everything from its body lines to its front-facing aerodynamic intelligent shield. On top of that, it sports a flat underbody that provides a smooth, user-friendly ride and cuts down on drag.

“With the growing shift towards electric mobility, aerodynamic testing is becoming increasingly important. The aerodynamics of electric vehicles are directly linked to how efficiently the vehicle moves – less drag and better stability allows the customer to drive longer distances before having to recharge,” explained Sarwar Ahmed, an aerodynamics and aeroacoustics engineer who’s bringing the Ariya to life at the Nissan Technical Centre.

I had no idea there was a shift in focus to this kind of testing for everyday vehicles. I have only ever heard of this for sports model cars and race cars. Interesting stuff!

Low drag is vitally important to minimise power consumption. The low drag coefficient of Teslas is key to their class leading efficiencies. Focus on this is why so many cars have similar shapes, completely smooth under-bodies and the array of air ducts and deflectors. The more limited energy storage capacity of EV's has made it even more important for "everyday" vehicles. The understanding of drag advanced massively during WW2 and some car designers took it on board as soon as the war ended. Look at a post war Jowett Javelin as an example. Other designers tended to ignore it but the performance differential gradually pushed them all in the same direction. EV and the high cost of fuel will continue the push particularly for hold-outs such as American pick-ups.
