Tires

Pollution from tires can be 1,000 times worse car exhaust according to Emissions Analytics

When tires come into contact with the road surface, they release pollutants.

Emissions Analytics, an independent global testing and data company that studies real-world emissions and fuel efficiency for passenger and commercial vehicles, has found that pollution and tire wear can be 1,000 times worse than what comes out of a vehicle's exhaust pipe.

Unlike exhaust pollution, tire and brake pollution is mostly unregulated. These other types of pollutants from a vehicle are referred to as non-exhaust emissions (NEE). According to Emissions Analytics, NEEs are currently defined as "particles released into the air from brake wear, tyre wear, road surface wear and resuspension of road dust during on-road vehicle usage."

Emissions Analytics says that NEEs are believed to constitute the majority of primary particulate matter from road transport. The 2019 report "Non-Exhaust Emissions from Road Traffic" by the United Kingdom Government's Air Quality Expert Group recommended that NEEs be recognized as a major source of pollution.

To determine what the effect of NEEs are on the environment, Emission Analytics conducted initial tire wear testing. They used a hatchback running on new, properly inflated tires and found that the car emitted 5.8 grams per kilometer of particles.

Current exhaust emission limits in the U.K. are 4.5 milligrams per kilometer. That means that the team found that NEEs pollute the environment 1,000 times more than the maximum allowable exhaust amount.

Emissions Analytics noted, along with the results, that this number could be even higher if the vehicle's tires were under inflated or if the road surfaces were rougher.

Richard Lofthouse, Senior Researcher at Emissions Analytics expressed concern regarding the findings, "It's time to consider not just what comes out of a car's exhaust pipe but particle pollution from tyre and brake wear. Our initial tests reveal that there can be a shocking amount of particle pollution from tires – 1,000 times worse than emissions from a car's exhaust. What is even more frightening is that while exhaust emissions have been tightly regulated for many years, tyre wear is totally unregulated – and with the increasing growth in sales of heavier SUVs and battery-powered electric cars, non-exhaust emissions are a very serious problem."

There are ways to reduce the effect of NEEs coming from your vehicle, including making sure that your tires are properly inflated, and reduce the weight of your vehicle as much as possible (don't carry around excess weight).

The new Mitsubishi Eclipse Cross used the Internet of Things to connect to the My Mitsubishi Connect app

Mitsubishi has enlisted Aeris and Dealer-FX to better connect owners to their vehicles. Using integrations with the Aeris Mobility Services and Dealer-FX ONE platforms, the My Mitsubishi Connect mobile app will now enable Mitsubishi Eclipse Cross drivers to view real-time service and maintenance needs, as reported by their vehicles.

The system will push timely notifications from the vehicle to the app and the owner's smart mobile device allowing them to act in a matter of seconds rather than trying to remember that a warning light cane in while operating the vehicle.

"Mitsubishi customers are dreamers, achievers, entrepreneurs – active in their communities and in their family homes, and their time is extremely valuable," said Mark Chaffin, Chief Operating Officer of MMNA. "The My Mitsubishi Connect app allows us to enhance their experience, be more efficient with their time and continue to demonstrate our commitment to delivering high quality, top value vehicles with leading-edge technology in the U.S."

This isn't the company's first IoT foray. When it debuted, Mitsubishi Road Assist+ was the first hardware-free, smartphone-based app provided by an OEM that allowed owners to realize the cost savings of usage-based insurance without having to own "connected car" with built-in telematics capabilities or aftermarket-installed telematics hardware.

Mitsubishi continues to grow its presence in the U.S. market. The company recently relocated its headquarters from California to the Nashville, Tennessee area near where Renault-Nissan- Mitsubishi Alliance member Nissan has its North American headquarters.

The company recently announced a partnership with the Nashville Entrepreneur Center to create the Small Batch - Big Ideas Entrepreneur Network, which gives entrepreneurs the opportunity to learn from Mitsubishi executives, among other benefits.

The My Mitsubishi Connect and Mitsubishi Road Assist+ apps are currently available on the Google Play store and the Apple's App Store for use on Android and iOS devices.

Truck drivers are no stranger to the challenges of towing. With updates to the GMC Sierra 1500 and Sierra Heavy Duty pickup trucks for 2021, the premium division of General Motors is adding a suite of customer-focused technologies to the make trailering easier.

"Trailering is essential for pickup truck customers. More than half of our Sierra customers use their trucks to primarily tow equipment for outdoor adventures," said GMC Marketing Director Rich Latek. "We continually listen to customer feedback, which tells us they want class-leading safety, technology and comfort to tow what they need, whether it's a boat, an RV or a trailer hauling off-road toys."

New or enhanced trailering tech available on both 2021 GMC Sierra light-duty and heavy-duty models includes:

  • Trailer Length Indicator - New for 2021, when enabled and driving forward with the turn signal activated, the center console screen displays a red overlay twice the length of the compatible trailer and shows when other vehicles are present and may interfere with a lane-change maneuver.
  • Jack-Knife Alert - New for 2021, Jack-Knife Alert tracks the position of the compatible trailer in relation to the vehicle. If the front of the trailer approaches the rear of the vehicle, an alert is displayed when there may be a potential jack-knife situation.
  • Rear Trailer View now features guidelines and Trailer-Angle Indicator: Rear Trailer View has been enhanced to include guidelines that assist when backing a trailer into place and a Trailer-Angle Indicator to show the relationship between the truck and compatible trailer. Rear Trailer View requires the customer-installed available GM auxiliary accessory camera.
  • Rear Side View enhancement - When driving forward on the 2020 GMC Sierra, Rear Side View provides a split view of the left and right sides of the truck and compatible trailer that is automatically biased based on the trailer's angle. In the 2021 GMC Sierra, drivers will have access to this view while driving in reverse, making it easier to see surrounding vehicles and objects while positioning a trailer.
  • Cargo Bed View enhancement - New Cargo Bed Zoom View and Bed Hitch Guidance are now available, which can be helpful for aligning and hooking up a gooseneck/fifth-wheel trailer.

Select trailering features require a conventional-hitched box or camping trailer and additional setup may be required. Customers can see their dealers for full details.

Additionally, GMC is expanding the availability of their MultiPro Tailgate to Sierra 1500 SLE and Elevation trim models, which will also be offered in a number of new paint colors. The 2021 GMC Sierra 1500 AT4 will be available with 20-inch Goodyear Wrangler Territory tires and off-road high-clearance step.

GMC is also reducing the price of its available 3.0-liter Duramax Turbo-Diesel engine by $1,500 for 2021 making it just $995 above the the Sierra 1500's 5.3L V-8 with Dynamic Fuel Management.

The 2021 GMC Sierra Heavy Duty Denali gets new standard equipment including HD Surround Visionn and Bed Video camera technology. The new Sierra HD Denali Black Diamond Edition will have several unique features, including exclusive 20-inch high-gloss black wheels and new power-retractable assist steps. Similar to the Sierra 1500, the Sierra Heavy Duty AT4 will now have available 18-inch Mud Terrain tires and an available off-road high clearance step accessory.

Other additions to Sierra HD include the MultiPro Tailgate standard on the SLE grade and three new available paint color options.

The 2021 GMC Sierra goes on sale later this year. Pricing will be announced closer to its on-sale date.
