Due to the COVID pandemic, the 2021 Work Truck Show was held in a virtual format. Manufacturers introduced new products via recorded presentations. Virtual demonstrations and educational seminars were also held throughout the week. Several of the most notable presentations centered around connected vehicle capabilities, electrification and new product walkarounds.

Ford Expands Connected Capabilities

“One hundred percent of Ford commercial vehicles include embedded modems with 4G LTE WiFi for up to 10 devices,” says Philip Podgorny, general manager, commercial and government sales, Ford Motor Company. These modems unlock connectivity to intelligent fleet management tools offered by Ford Commercial Solutions.

Ford Telematics is a modern, web-based product that gives customers access to vehicle health reports, vehicle location, driver behavior and more,” says Alex Purdy, Director of Business Operations, Enterprise Connectivity, Ford Motor Company. “Now, with the benefit of modems embedded into the electrical architecture of every new Ford, we have direct access to vehicle systems and architectures so we can offer unique services like remotely locking or unlocking a single vehicle or group of vehicles, remote scheduled preconditioning and the ability to offer predictive maintenance and trouble alerts to help you stay ahead of potential downtime issues.”

A Ford telematics drive mobile app can help drivers identify physical issues that can not be spotted by a telematics system, such as a broken mirror or worn tires.

Ford Telematics features an updated dashboard that makes visualizing the important information about your fleet and spotting the key trend and insights easier. Ford telematics already works with all model year 2020 or newer Ford vehicles without any additional hardware. “Last year we added a Ford plug in modem kit for older Ford vehicles, giving fleet managers greater visibility into their entire fleet,” notes Purdy.

“Today, we’re happy to announce that Ford Telematics is now compatible with non-Ford vehicles by a plug-in device,” he adds. “Now you can gain clear, easy to access insights for Ford Telematics across your entire fleet, regardless of make.”

A driver behavior dashboard gives managers a survey of how their vehicles are performing, providing information about trends that involve harsh braking or acceleration, speeds driven over posted limits and/or fleet-set thresholds, seatbelt use and idling time. A personal driver score also lets fleet managers quickly see how specific drivers are doing, giving them opportunities to further coach them on best practices and areas of improvement.

Further bolstering Ford’s mission to improve uptime for commercial fleets is the widespread adoption of over-the-air (OTA) update capability, beginning with the 2022 F-150. Vehicles equipped with this technology can receive updates and repairs wirelessly, reducing the need to visit a dealer for maintenance.

XL Fleet Develops Plug-in Hybrid for GM HD Pickups

XL Fleet has electrified many common commercial and fleet applications with hybrid and plug-in hybrid electric (PHEV) drive solutions for vans, pickups and stripped chassis. At the virtual Work Truck Show, the company announces a plug-in hybrid electric drive system for select Chevrolet Silverado and GMC Silverado 2500HD/3500 HD pickup trucks and the Chevrolet and GMC 3500 and 4500 chassis cabs. The pickup truck solution will be available in the first quarter of 2021 with availability of the chassis cab solution in the second quarter. “It is the first PHEV system that is now available for GM fleet products,” says Eric Foellmer, director of marketing, XL Fleet.

This technology transforms a factory OEM vehicle into a more fuel-efficient hybrid that reduces fuel consumption by up to 50% and cuts CO2 emissions by a third. The system adds an electric motor, an advanced lithium-ion battery pack and control software to the existing vehicle. No other significant modifications to the vehicle are required and no changes are made to the internal combustion engine or transmission. “Our system is all deployed post transmission, so the warranty from GM remains intact,” notes Foellmer.

The heart of the plug-in hybrid electric drive system is the high-efficiency 15-kWh lithium-ion battery pack. “The lithium-ion battery pack gets its power from two sources,” says Foellmer. “The first is the electric motor that sits on the drive shaft. During deceleration regenerative braking power is stored in the battery pack. In addition, you can plug in the charger either overnight or during the day.”

An electric motor is mounted directly onto the driveshaft. “When the driver accelerates, the motor adds an additional 220 ft.-lbs. of torque directly into the driveline,” explains Foellmer. “The result is less wear on the engine, reduced gas consumption and fewer emissions. When the driver decelerates and hits the brakes, the electric motor turns into a generator and stores that energy back into the battery pack so that it can be used again the next time the driver accelerates.”

On GM’s HD pickups, the plug-in hybrid system is available on the 6.6-liter engine with the 4x4 driveline. “It’s available on 149-in. wheelbases and up and it’s available on double or crew cab options in any bed size.” On the GM 3500 and 4500 chassis configurations, the system is available on 6.6-liter engines across all wheelbase types.

Cummins provides overview of new EPA2021 L9 engine

Cummins Inc. introduces its EPA2021 L9 engine, which lowers carbon dioxide emissions while increasing efficiency and fuel economy. The company did so by improving its existing engine technology instead of redesigning its L9 engine platform.

These were achieved through the head gasket material and capability improvements to handle the most aggressive application duty cycles and temperature environments.

Internal hardware improvements were made to the turbocharger actuator, and improvements were made to cooling venting to handle challenging running and hot shutdown conditions. Cummins also improved the EGR valve design to increase reliability and resist faults. Additionally, the engine block’s oil pan rail and oil pan gasket were re-engineered to improve sealing capability.

To enhance performance, Cummins lowered peak torque speed of the engine so it provides full torque over a wide operating range. Kiesler says this improves drivability with less downshifting required on grade.

Parasitic losses were reduced as well to get the most of every drop of diesel while meeting current emissions regulations. This was achieved through reduced and optimized piston ring tensions and coatings. Camshaft valve timing was modified to reduce pumping work in the air handling system. Water pump speeds were also optimized to provide required system cooling without unnecessary coolant flow.

Kiesler says with these improvements, Cummins was able to create an engine which meets the EPA 2021 GHG Phase II requirements without having to introduce new technologies or sacrificing reliability and durability.

To help meet the GHG emissions requirements, Cummins’ engine control module features increased computing capabilities to enable thousands of calculations required per second which are necessary to ensure compliance and run diagnostics. “All this is done while keeping the interface to the OEMs common with the EPA 2017 product,” notes Kiesler.

Fuel efficiency improvements up to 3.5% on the Performance Series engines and up to 1.5% for the Productivity Series have so far been seen with these new L9 engines.

Mack Trucks highlights MD series, Granite updates

Mack Trucks began production of its MD Series trucks—the model which brought the company back into the medium-duty market—in September. Since then it has started delivery of the trucks to dealers and customers. According to Jonathan Randall, Mack Trucks senior vice president of North American sales and Commercial Operations, there has been increased interest for the trucks and they are so far exceeding customers' and dealers' expectations.

The company also discussed the recent updates to its Granite models, one of which was the introduction of Command Steer active steering. The system uses multiple sensors to receive input, more than 2,000 times per second. It monitors road conditions, driver inputs and environmental elements to provide a safer driving experience. Command Steer can hold the lane when unexpected changes occur such as wind gusts, uneven pavement, ruts in the ground or even tire blowouts. "It also provides featherlight steering at low speeds; so light you can steer it with your finger," says. Tim Wrinkle, construction product manager at Mack Trucks. "It minimizes the daily strain on drivers, and it's a great tool for driver retention and recruitment.

Mack Trucks has achieved weight savings on its mRIDE spring leaf over rubber block suspension.

Western Star designed a new purpose-built cab for the 49X. The company claims the X-series cab is the largest in the segment with 10% to 13% greater space than competitive cabs. It was designed specifically for vocational applications and provides additional vehicle weight savings while delivering long-term durability and operator comfort. Advanced topology was utilized to ensure rigidity and strength and determine where more material was needed in the steel-reinforced aluminum cab.

The hood of the 49X is constructed of high-strength, lightweight, molded composite for impact resistance and durability. The new hood uses a patented ISO Tech Hood Suspension system that behaves similarly to a typical coil-over shock suspension system with spring and damper. The system isolates, absorbs and dissipates vibrations from the chassis when driving over uneven terrain to protect the hood from damage and cracking.
