Charging on the go can be one of the biggest obstacles in electric vehicle adoption. Jaguar Land Rover (JLR) has entered into a public-private partnership with the City of Oslo, Norway to support their high-powered wireless taxi program.

The partnership is part of a larger initiative called ElectriCity, which includes Nordic taxi operator Cabonline (NorgesTaxi AS), the region's largest charge point operator Fortum Recharge, U.S. technology developer Momentum Dynamics, and the City of Oslo. ElectriCity's goal is to build a wireless, high-powered charging infrastructure for taxis in the Norwegian capital. JLR will provide 25 all-electric Jaguar I-PACE models to Cabonline, the largest taxi network in the Nordics.

ElectriCity will produce the first wireless high-powered charging system for electric taxis in the world.

According to a release, engineers and technicians from Momentum Dynamics and JLR engaged to help in testing the solution, and Cabonline signed up to operate the fleet as part of Oslo's ElectriCity program. Fortum Recharge will support the installation and electrification efforts.

The Jaguar I-PACE, the brand's first all-electric vehicle, has been designed to enable Momentum Dynamics' wireless charging technology.

According to research, both electric taxi and driver efficiency can be maximized when charging does not require taxis to leave their route. In order to make wireless charging work, wireless charging plates, rated at 50-75 kilowatts each, are installed in the ground in series at pick-up-drop-off points.

This allows each equipped taxi to charge while queuing for the next fare. The system, which uses no cables and situated below ground, requires no physical connection between charger and vehicle, engages automatically and provides on average 6-8 minutes of energy per each charge up to 50kW.

Each taxi can receive multiple charges throughout their shift.

When the chargers are installed, Oslo will be the world's first metropolitan area to install wireless, induction-based high-powered charging stations for electric taxis, in a bid to make its cab system emission free as early as 2024.

Per capita, Norway has more electric car owners and drivers than any other country in the world. The country has highly incentivized and regulated the adoption of the vehicles. Norway is mandating that all new cars sold in the country by 2025 are zero emission vehicles.

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 Porsche Taycan Cross Turismo will be the next member of the company's all-electric family.

There's a new Porsche car coming and despite the way it looks, it's not a fresh all-electric Panamera. It's the Porsche Taycan Cross Turismo. The car was spied on the roads east of Weissach, Germany, doing its finally testing wearing very little camouflage.

We already know that the underpinnings of the new car are pretty much the same as what's in the Taycan sedan. Its outside isn't too dissimilar from the Taycan either, with much of the face holding the family looks and its back getting a sport wagon treatment that's similar to the Panamera - new fenders a longer roof, and a hatchback. The car also has an increased ride height.

And that's just what we can see from the photos. The car was darting along the countryside between frozen farmland and snow-covered forests. Porsche has confirmed many of these details and they were the ones that released the photos of the car testing - something usually left up to a spy photographer but in a COVID world, here we are.

They also released a video showcasing the car and its testing journey, featuring Stefan Weckbach, Vice President of the Taycan product line at Porsche. Take a watch.

Just a few days later, Porsche released video of the inside of the Taycan Cross Turismo, giving enthusiasts a peek behind the scenes on its development.

The Porsche Taycan Cross Turismo is expected to be fully revealed later this year.
