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:

Volkswagen nixing Passat after 2022 model year

Racing Green Metallic is one of four exclusive colors for the car.

Volkswagen

After five decades on sale in the U.S., Volkswagen is pulling the plug on the midsize Passat. The explosion of SUVs' popularity and the need to shift production power to electric vehicles are behind the decision, which will take place after the 2022 model year. The cars have been built at the automaker's Chattanooga, TN plant since 2011, but the facility is being repurposed as VW's North American hub for electric vehicle assembly.

Volkswagen is giving the car one last hurrah, however, in the form of the Passat Limited Edition. The car features 18-inch wheels, LED headlights with an Advanced Front Lighting System, and an easy-open trunk. Inside, the cars come with sport seats wrapped in Vienna leather, memory seating, a Fender Premium Audio System, parking assistance, and parking sensors.

Only 1,973 of the cars will be built, and it will only be sold in four colors, each with its own limited production numbers that have special meaning for the Passat:

  • Aurora Red Metallic with Titan Black interior: 411 units to represent the original vehicle production code
  • Racing Green Metallic with Mauro Brown interior: 423 units to commemorate the Chattanooga 423 area code
  • Pure white with Mauro Brown interior: 524 units to signify the Chattanooga plant's May 24 opening date
  • Platinum Great Metallic with Titan Black interior: 615 units to signify six generations of imported Passats, one generation assembled in Chattanooga, and five decades of U.S. sales

Pricing for the 2022 Passat starts at $31,290, which includes a $995 destination fee. Adding Aurora Red Metallic drives the price up by an additional $395. Each car will receive a special number plate to designate its place in the limited production run.

The 2022 Frontier gets a brand-new face and updated tech.

Nissan

After 16 years on sale in its current form, the Nissan Frontier is a familiar face on our roads. The truck, which is technically old enough to get a driver's license and drive itself, is being totally overhauled for 2022, and the new look is a big departure from the ute we've seen for so many years. Nissan announced that production has started, so we don't have much longer to wait to see it in action for ourselves.

The new truck's 3.8-liter V6 has already been in action powering the 2021 Frontier. It produces a class-leading 310 horsepower and 281 pound-feet of torque, and sends its power to either the rear or all four wheels through a nine-speed automatic transmission.

This is the first new Frontier we've seen in over a decade, so the upgrade in technology is steep over the previous truck. The 2022 Frontier can be optioned with a surround-view camera system with off-road mode that automatically displays terrain around the truck when it's shifted into 4LO. The system displays guidelines and can help the driver navigate tough obstacles on the trail. A host of safety features will be available that includes automatic emergency braking, blind spot monitoring, rear cross-traffic alerts, lane departure warnings, high beam assist, and more.

Other than its age, there was nothing particularly wrong with the previous Frontier's interior, but the new truck looks to be considerably more upscale and modern. Various trims come with interesting contrasting color schemes and the truck gets Nissan's excellent Zero Gravity seats as standard. New hydraulic cab mounts should help quell vibrations inside, and traditional hydraulic power steering will provide excellent steering feel and feedback.

Nissan is building the new frontier in its Canton, MS facility, while the truck's engine is being built at the automaker's powertrain plant in Tennessee. We'll start seeing the new model on dealers' lots sometime in late summer 2021, and you can find a first drive review of the truck right here in a few weeks.
