Ariya is the most aerodynamic crossover Nissan has built, but it lags behind EV rivals

Nissan is targeting a drag coefficient (Cd) of 0.297 for the Ariya all-electric crossover. If it can make that number, it will be the company's most aerodynamic crossover to date. What does that mean? Let's take a closer look.

What is drag?

Simply put, drag is an aerodynamic force. It's mechanical in nature, so it is the result of the interaction of a solid body and a liquid. In the case of a car, this liquid is air. (Yes, air is a liquid.) It only occurs when one part of the equation (the solid body or the liquid) is in motion. If there is no motion, there is no drag.

Drag only occurs in the opposite direction of the object's movement. Think of a car cutting through the air as it drives down a north-south road. As the car heads north, the air it passes through is pushed south. The car is in motion; there is drag.

What is coefficient of drag?

The coefficient of drag, also called a drag coefficient, is a number that aerodynamics professions (aerodynamicists) use to determine the shape, inclination, and flow conditions on a vehicle's drag. The shape of an object (bullet vs. square vs prism, etc.) has a large impact on the amount of drag created by airflow surrounding a vehicle. Objects with narrower front ends tend to have a lower coefficient.

Scientists and vehicle designers want to keep air moving around the car for maximum efficiency. The inclination of the airflow to either move in a smooth, connected pattern, or to be broken up with air sitting, stalling in one particular part of the vehicle, lessening airflow and making the vehicle less aerodynamic.

A vehicle's Cd is determined by plugging various measurements into an equation. Cd is equal to drag (D) divided by the quantity of density (r) multiplied by half the velocity (V) squared multiple by the reference area (A). As an equation, it looks like this: Cd = D / (A * .5 * r * V^2).

The smaller the Cd, the more aerodynamic a vehicle is.

What is the coefficient of drag of the Nissan Ariya?

"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," said Sarwar Ahmed, Aerodynamics and Aeroacoustics Engineer at Nissan Technical Centre Europe.

Nissan is targeting a 0.297 coefficient of drag for the Ariya. How will it achieve that number? By utilizing precisely shaped body lines and strategically placed air ducts, among other components. There's a bonus to better aerodynamics when it comes to EVs.

"Following official homologation of the Nissan Ariya later this year, we anticipate the range to improve compared to the 310 mile figure shared in 2020 during the World Premiere. This will give drivers more efficiency and confidence to go even further on a single charge," said Marco Fioravanti, VP Product Planning, Nissan Europe.

How does the Ariya's coefficient of drag compare to other Nissans?

The newest Nissans, the Kicks, Pathfinder, and Frontier, don't have their Cd publicly available yet, but other models have their results. The targeted 0.297 Cd in the Ariya is less than that in the 2021 Armada, Murano, and Rogue. But, it's higher than the Nissan Leaf.

The fact that it's higher than the Leaf is not surprising. Shorter cars tend to be more aerodynamic because they sit lower to the ground and have a smaller profile. That also explains why Nissan's largest and boxiest SUV, the Armada, has the highest number on the list.

How does the Ariya's coefficient of drag compare to numbers from other EVs?

The Nissan Ariya's coefficient of drag is higher than that of most other electric cars, crossovers, and SUVs sold in the U.S. Here's where the others measure up:

The 11th-generaiton Honda Civic Sedan has broken cover.

Marie was a little bit country and Donny was a little bit rock and roll. The design of the redesigned 2022 Honda Civic Sedan looks a little bit modern and a little bit vintage - and it's all a heck of a lot less polarizing than the previous generation.

Today Honda has offered the first official fully lighted glimpse of the 11th-generation Civic, which is set to officially debut April 28. The design of the model was previewed last year with the Civic Prototype.

Honda openly admits that the look of the new Civic was inspired by the last. Head into the trove of internet photos of the fourth- and fifth-generation Civic to see parallels in design. Honda said that designers upheld Honda's human-centric design philosophy in the new model while also increasing the safety.

The result is a car that looks very much like a sedan but still retains sporty attributes. It also looks more like the Accord in this generation than the last. In the photo provided by Honda, the new Civic is in Touring trim level form.

Honda said that the car's interior design, which they haven't shown photos of yet, is "uncluttered", has "simple ergonomics", and delivers "exceptional visibility".

The 2022 Civic will arrive on dealership lots this summer.

Also this summer, the Honda Civic Tour will return for its 20th season. There will be two stops on the virtual tour that will be livestreamed on the Honda Stage YouTube channel. The first event will start at 5:00 p.m. PT, on April 28. The virtual concert event on Twitch will also give Civic Tour fans a special first look at the all-new 2022 Honda Civic Sedan around 6:00 p.m. PT, leading into the performance.

As previously announced, the all-new Civic Hatchback will follow Civic Sedan production by several months. Details about Civic Hatchback, to be manufactured by Honda in the United States for the first time in its history, will follow later this year. The Civic Hatchback will be built at the company's Indiana auto plant.

David Beckham is the new face of Maserati.

David Beckham is turning his passion for supercars into a side gig. The former Manchester United midfielder has become the new face of Maserati.

Beckham has a long history as a car nut. He's owned Rolls-Royces, Bentleys, McLarens, Cadillacs, Audis, Aston Martins, Jaguars, BMWs, Lamborghinis, Ferraris, Hummers, and Jeeps, just to name a few. A year ago an Aston Martin Volante owned by Golden Balls went under the hammer and a little later in the year he was named one of the top five celebrities people would prefer to have deliver their new car to their home.

Maserati has a number of new projects up its sleeve besides partnering with Beckham. The company recently launched the new Ghibli Hybrid, a vehicle that the Modena-based manufacturer sees as a jumping off point for the new version of the brand - one where electrification and performance take center stage. Call it the Italian version of Akio Toyoda's famous "no boring cars" statement.

"The Brand is moving forward, inaugurated a new Era. Maserati is driven to challenge the status quo being innovative by nature, powered by passion, and unique by design. The partnership with David is the embodiment of all these values,: said Paolo Tubito, Maserati Chief Marketing Officer.

For 2021, Maserati also added a trio of Trofeos to its lineup. The The Maserati Levante Trofeo,. Ghibli Trofeo,and Quattroporte Trofeo are the most extreme versions of the vehicles available new from the manufacturer.

Beckham makes his debut in a new movie featuring the Levante Trofeo, performing the "audacious" act of driving a Maserati. The setting is Miami, the home city of Club Internacional de Fútbol Miami, an MLS soccer club that Becks co-owns with Marcelo Claure, Jorge Mas, Masayoshi Son, and José R. Mas.
