Opening your car windows could reduce your COVID-19 risk

By now, we all know the basic coronavirus rules. Wear a mask, limit your exposure to other people and when you can’t, keep your distance, and … keep wearing your mask. We also learned at the outset of the pandemic how to properly keep surfaces clean, including in your car. But what we haven’t known is whether we should keep the windows up or down.

A new study from Brown University seeks to answer that question. Using complex computational fluid dynamic simulations, Varghese Mathai, Asimanshu Das, Jeffrey Bailey and Kenneth Breuer studied how the aerosols that we breath (some of which do escape even properly worn masks) move about a car’s cabin and how those flows change with various windows up and down. The results are very interesting, but in short, you’re probably going to want the windows rolled down when possible.

The details of the study are worth noting. The vehicle used in the simulations was loosely based on a Toyota Prius, and likely apply to vehicles of similar shape and size but may not be applicable to larger or smaller cars, trucks or vans. The occupants sat diagonally from one another, which is a common arrangement in taxis and rideshares. The team of researchers found that opening the windows opposite of each occupant can create a flow that drastically reduces the collection of aerosols in a car’s cabin. According to the New York Times, they also found that opening the windows even halfway can be very helpful but that just cracking them a bit doesn’t generate enough airflow.

There’s a lot more information in the study that you can read here. There’s also some additional information from the Times that’s worth checking out.

GMC Sierra to Feature Super Cruise Hands-Free Driver Assistance Technology

GMC Sierra to Feature Super Cruise Hands-Free Driver Assistance Technology

The latest version of Super Cruise featuring trailering capability will be available on the GMC Sierra 1500 Denali late in the 2022 model year

2020-12-09

DETROIT – Super Cruise1 driver assistance technology will launch on the Sierra 1500 Denali in late model year 2022. The Sierra 1500 Denali will have the latest version of Super Cruise including the introduction of the ability to trailer while driving hands free.

The industry’s first true hands-free driver assistance system, Super Cruise is available on more than 200,000 miles of compatible roads in the U.S. and Canada.

Super Cruise utilizes a driver attention system and precision LiDAR map data in addition to real-time cameras, sensors and GPS. The driver attention system uses a small camera located on the top of the steering column and works with infrared lights to determine where the driver is looking whenever Super Cruise is in operation. If the driver attention system detects the driver has turned their gaze away from the road ahead for too long, the steering wheel light bar will prompt the driver to return their attention to the road.

Off-Road Performance Edition Takes GMC Canyon AT4 to New Heights

Off-Road Performance Edition Takes GMC Canyon AT4 to New Heights

Suspension leveling kit, rocker panel protectors and aluminum skid plates among features that elevate the confidence and capability of the Canyon AT4

2020-11-16

DETROIT – Today, GMC announced the new 2021 GMC Canyon AT4 Off-Road Performance Edition, which enhances the Canyon AT4 and enables customers to confidently venture into rugged off-road environments, all while maintaining the premium comforts they have come to expect from GMC.

“When customers are looking for a capable off-road truck, we know that they want improved vehicle height as well as additional protection,” said GMC Marketing Director Rich Latek. “Whether it’s tackling die-hard off-road courses or embarking on a weekend adventure, the Canyon AT4 Off-Road Performance Edition provides an improved approach angle, enhanced maneuverability and underbody protection to key parts of the truck, while still delivering a premium GMC experience.”

When the Canyon AT4 debuted in January, its bolder design and premium detailing combined with confidence-inspiring capability signaled the brand’s continued commitment to offering premium, off-road capable vehicles.

Standard equipment on the Canyon AT4 includes 31-inch Goodyear Wrangler DuraTrac® tires, an off-road tuned suspension package with Advanced Hill Descent Control System and a four-wheel drive system with Eaton G80 Rear Automatic Locking Differential.

The Canyon AT4 Off-Road Performance Edition builds on this foundation to provide even more capability for drivers whether they’re venturing far off-road or navigating a trail. A suspension leveling kit and the removal of the front air dam improve the truck’s approach angle by more than 35 percent to nearly 30 degrees.

This increased approach angle is paired with rocker panel protectors and performance front and mid skid plates to provide increased off-road capability and maneuverability. The skid plates are made from sturdy, 5/32-inch aluminum and help protect the lower radiator, front differential, steering gear and oil pan. In combination with the transfer case shield standard on the Canyon AT4, the Off-Road Performance Edition offers the protection to the majority of the truck’s powertrain that off-road enthusiasts expect.

The Off-Road Performance Edition elevates the bold styling and premium refinement of the Canyon AT4 with the addition of:

  • Unique 17-inch Gloss Black wheels
  • Carbon Black AT4 logos
  • Gloss Black performance exhaust tip

After a day of off-road adventure, additional protection for the interior and the truck bed is provided in the form of accessory floor liners and spray-in bedliner.

The 2021 Canyon AT4 Off-Road Performance Edition will be available to order later this year. For more info, visit www.gmc.com.
