Such a Tease

The Maserati Grecale is expected to be revealed later this year. Ahead of that debut, the company has taken a unique approach to showing off the camoflauge-wrapped SUV - they released photos to company employees with instruction to distribute them on social networks rather than sending them to the press.

The employees obliged. One of the first to do so was Bernard Loire, Chief Commercial Officer at Maserati.

Each of the three photos distributed shows the Grecale outside the historic Maserati plant on Viale Ciro Menotti in Modena, Italy. The prototype cars are currently undergoing a period of intensive road, circuit and off-road tests, in various conditions of use, to acquire vital data for the preparation of the new SUV's final setup.

The Maserati plant is the same place where the Alfa Romeo Stelvio is built, in Cassino, Italy. Maserati will invest 800 million Euros to get the plant ready for production.

The 2022 Maserati Grecale will be the little sister of the Maserati Levante. It is expected to compete directly with the Porsche Macan in a hot luxury compact SUV market.

Maserati has said that it will offer a hybrid and battery electric (BEV) version of the Grecale, but expect to see the hybrid before the BEV.

The automaker is also expected to create a high-performance variant of the SUV, giving it the Trofeo name. Maserati currently sells the Levante in Levante, Levante S, Levante GTS, and Levante Trofeo grades. The Grecale could follow suit.

The larger Levante starts at $77,890 and tops out over $152,000. It's likely that the Grecale will be priced lower, possibly starting around $50,000. A range-topping Trofeo could be priced over $100,000.

Not much else is known about the Grecale at this point. It's likely that Maserati will continue to tease the model, revealing it little by little until the full cover comes off, if the reveal of the company's MC20 sportscar is any indication.

The Maserati Grecale will debut before the end of 2021.

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 long process to design, engineer, and award a contract for the U.S. Postal Service's (USPS) next-generation mail delivery vehicle (NGDV) has finally come to an end. The government has awarded Oshkosh Defense a contract to produce the Next Generation Delivery Vehicle for service. Oshkosh Defense is a a wholly owned subsidiary of Oshkosh Corporation (NYSE: OSK).

The NGDV project is the USPS's first large-scale fleet procurement in three decades. Over the next 10 years, the contract allows for the delivery of between 50,000 and 165,000 new vehicles.

"Oshkosh operates with unparalleled commitment to those who depend on our products and services to build, protect and serve communities around the world. We are honored to have been selected by the USPS to support their important work by manufacturing American-made Next Generation Delivery Vehicles that will connect every home and business across the United States for decades to come," said John Pfeifer, President & Chief Operating Officer, Oshkosh Corporation.

The new mail trucks will have multiple powertrain options, just like many passenger vehicles on the road today. There will be a battery electric vehicle (BEV) version that runs exclusively on electric power and a fuel-efficient low-emission internal combustion engine vehicles (ICE) variant.

Under the contract awarded today, USPS has committed to paying Oshkosh Defense $482 million as a first step toward the new vehicles' production. The money will be used to finalize the production vehicle design and complete factory build-out, all of which is necessary before production gets underway. The process is similar to ones mass market vehicle manufacturers use.

"Our century-long history of delivering products to customers, operating in some of the most demanding and severe conditions on the planet, uniquely positions us to bring exceptional reliability, safety, and maintainability to USPS's Next Generation Delivery Vehicles," said John Bryant, Executive Vice President, Oshkosh Corporation, and President, Oshkosh Defense. "Partnering with trusted suppliers, we have developed a purpose-built solution to support the current and future needs of the USPS," Bryant concluded.

In addition to a new exterior and powertrain options, the NGTV also gets modern features and amenities like a rearview camera, walk-in cargo area, air condition, telematics, and a sliding cargo door. There's also a host of safety technology and equipment including airbags, automatic front and rear braking, blind spot warning, a 360-degree camera, and forward collision warning.

Production of the next generation delivery vehicle is expected to begin in 2023.
