If you’ve ever thought that the medium-duty market is a case of “the more things change, the more they stay the same,” it might be time to take a second look.

While there’s electricity in the air across the trucking landscape, even some truck makers that have already shown off their prowess advancing battery-electric powered trucks for medium-duty use are also responding strongly to heightened back-to-the-future demand for gasoline-fueled trucks.

Other hot trends in the bread-and-butter world of workaday delivery and vocational trucks include sustained efforts to bring even more highly advanced safety technologies to bear, as well as boosting vehicle connectivity to reduce operating costs, and finding ways to make trucks just plain more comfortable to drive.

For instance, Mitsubishi Fuso, which laid claim last year to rolling out the first global all-electric truck in full production, has this year introduced specifically to North America the only gasoline-powered truck that it makes. Other brands offering gas power in this space include Isuzu, Mercedes-Benz, Nissan, and Ram.

In the electric realm, Daimler has begun testing an electric version of the Freightliner M2 106 truck. And Isuzu, according to Brian Tabel, executive director of marketing, planned as of October to continue piloting five different trucks with five different customers to test its battery-electric truck in conjunction with electric drivetrain maker Nordresa.

It’s been well proven that nowadays, safety sells – and very well. “Large fleets are driving the spec’ing of safety technology to the industry,” says Ford’s Kevin Koester, medium-duty truck and Super Duty fleet marketing manager. “Collision avoidance and automated emergency braking are at the top of the wish list for large fleets, both to protect the driver and the power unit.”

Chad Semler, Navistar’s director of product marketing, concurs. “The large fleets that use medium-duty trucks are more and more safety conscious,” he says. “This is shown by their increasing focus on active safety technologies, such as collision mitigation systems. Fleets’ safety focus is also reflected in their growing interest in enhanced visibility, safe ingress and egress, and ergonomic interiors.”

“For the medium-duty segment, safety features and telematics solutions as seen in our Class 8 trucks are becoming more prevalent,” says Kelly Gedert, director of product marketing for Freightliner Trucks and Detroit Components. “Wabco safety systems are available in the Freightliner M2 106, providing a great option for medium-duty fleets to contribute to the increased safety for their own drivers and other drivers on their routes.”

Yet despite all the things advanced technology can deliver, a truck is at heart a business tool. “It’s not just numbers on a spec sheet that makes things different and better,” says John Schwegman, director of commercial product and medium-duty for GM Fleet. “For example, our new [Chevrolet] Silverados are designed to solve the most common upfit and ownership challenges fleets have.”

Among those ownership challenges? Downtime.

“The days of fleets keeping multiple spare vehicles on hand to cover broken-down vehicles are gone,” adds Ford’s Koester. “Fleets expect and demand higher quality in the manufacturing process, and the same expectation exists for reliability once the truck is in service. In order for our brand to have a presence as a preferred vehicle in a large fleet, we must meet their expectation that the manufacturer and dealer have a priority to get that vehicle back on the road as soon as possible.”

The big truck news out of General Motors is the return of Chevrolet to the medium-duty market with an all-new lineup of Class 4 to Class 6 chassis- cab models for the 2019 model year, consisting of the Silverado 4500HD, Silverado 5500HD, and Silverado 6500HD. The three models were developed via a partnership with Navistar. Together, the models cover GVWRs running from 15,000 pounds to 22,900 pounds and offer seven wheelbase options as well as regular and crew cab variants. The Silverado HD models will be available in two- and four-wheel drive and will be powered by a Duramax 6.6L turbodiesel, rated 350 hp at 700 lb.-ft. of torque, mated to Allison automatic transmissions. A power take-off is optional. GM says the frame is designed with one-piece straight rails with no rivets or brackets on top to interfere with the mounting of custom-made bodies. In addition, more frame lengths are offered to help customers specify the exact truck to suit their needs. Serviceability features include a “clamshell” tilting hood and a wheel cut of up to 50 degrees that can give technicians better engine access than trucks with conventional hoods. Optional equipment includes twin-tank fuel capacity of up to 65 gallons, a factory-installed air suspension, and a suite of available connectivity offerings including OnStar, Commercial Link, and a built-in 4G LTE Wi-Fi hot spot. The Silverado HD boasts a design cue from the Chevy Camaro: The “flowtie,” first introduced on the front grille of the 2014 Camaro Z/28, is the chrome outline of the traditional Chevrolet bowtie with the center removed to increase engine airflow to help improve performance. In addition to the three new conventional-cab Chevys, GM also continues to offer the Class 3 Chevrolet Silverado 3500HD and GMC Sierra 3500HD chassis cab as well as its line of Chevrolet medium-duty low cab forward trucks.

The Detroit DD5 and Detroit DD8 midrange diesels are available for spec’ing on Freightliner M2 106 medium-duty trucks. The DD8 is engineered to be a low-maintenance, higher torque and higher horsepower option for fleets operating in construction, dump, mixer, plow, and other tough-duty applications. The DD5 is designed for typical urban applications, such as last mile and P&D.

“These engines boast industry-leading maintenance intervals and come standard with Detroit Connect Virtual Technician remote diagnostic service,” says Kelly Gedert, director of product marketing, Freightliner Trucks and Detroit Components.

“The engines also help medium-duty customers achieve maximum uptime with proprietary variable cam phasing, which enables more efficient aftertreatment system performance. At low engine speeds, the exhaust timing can adjust and open the exhaust valves earlier in the operating cycle. This causes warmer exhaust to be pushed in the direction of the aftertreatment system. And this allows for effective DPF regenerations, increasing uptime with reliable operation of the aftertreatment system.”

The DD8, launched at this year’s Work Truck Show, expands on the Detroit medium-duty platform that was rolled out last year with the DD5. Daimler says the DD8 will feature both engine and transmission power take-off options. The newer engines will initially be available in the Freightliner M2 106, 108SD and 114SD models. Trucks powered by the DD8 will also feature Detroit Connect Virtual Technician remote diagnostic service.

Daimler says Virtual Technician helps fleets make informed maintenance decisions, so vehicles are only serviced when needed. Should a vehicle need to go into the shop, Virtual Technician, backed by experts at the Detroit Customer Support Center, will provide access to in-depth information to help improve uptime.

Navistar will unveil its new Class 4 and 5 International truck, developed in partnership with GM, this month. Earlier this year it revealed its new MV Series Class 6 to 7 trucks. The MV Series is the final piece of International’s Project Horizon product refresh strategy, and aimed to improve medium-duty cab design by including the same “driver-centric features” found in the company’s Class 8 vehicles. The MV was designed to be easily configured for varying applications.

Key features include new cab doors with a lower bottom glass edge and removed vent window, giving the driver a single large piece of glass to improve side visibility and reduce blind spots. The position of the optional pedestal mirrors was optimized so drivers turn their heads less and keep their eyes on the road while reducing neck strain. A new gauge cluster with a digital driver display gives drivers real-time monitoring of vehicle operation and other important alerts in clear sight.

The flat-panel dash contains space for up to 30 customizable switches to operate any type of body that is mounted; the switches boast large text and are backlit for easy viewing at night. A column-mounted stalk shifter was chosen to help keep drivers’ hands on the wheel and eyes on the road.

The MV Series is also equipped with an improved HVAC system, which includes a high-performance “Max” defrost feature. An additional vent has been added to help keep the middle front passenger comfortable. MV trucks can be ordered with regular, extended, and crew cabs. The vehicle can be powered by either a Cummins B6.7 or L9 engine. Standard transmission is the Allison 1000 HS automatic. Optionally available are Allison FuelSense 2.0, with DynActive Shifting, which features a torque converter to provide variable shift points based on vehicle operating conditions.

For Mitsubishi Fuso, Daimler AG’s Japan-based medium-duty truck division, its biggest rollout this year is the Fuso FE Gas, the only gasoline-powered truck that the OEM makes. Aimed at the U.S. and Canada markets, it is being built in the U.S. with the company’s Daimler brand partner, Freightliner Custom Chassis Corp.

A General Motors-sourced 6.0L V-8 will power Class 4 and Class 5 FE Gas models. In all models, the gasoline engine will turn out 297 hp and 361 lb.-ft. of torque. The gasoline engine will be paired with an Allison 1000 automatic transmission with Fuel Sense 2.0 transmission management software, including DynActive shifting technology that is said to improve fuel economy by as much as 6%.

The software uses a Neutral-at-Stop feature to help further reduce fuel consumption. Both the FE Gas and FE Diesel models also boast a new interior, which features a heavy-duty driver’s seat with adjustable lumbar support.

In addition, the seatbelts are now red for higher visibility. Also, instrument cluster colors have been improved under various lighting conditions, and there is now an LED cabin light. Storage space has been improved, too, with a new driver side console, floor tray, and sun-visor pocket. And the FE Diesel now has a new transmission, the Fuso Duonic 2.0 6-speed dual-clutch automatic. The upgrade to the 2.0 version includes modification of the dual clutch that significantly improves reliability, comfort and operability, says the company.

In addition, it adds Hill Start Assist, and the gear shift shock has been considerably reduced to provide a smoother drive. The Duonic 2.0 maximizes power transmission efficiency by quickly switching between the two clutches, according to the OEM.

Peterbilt medium-duty truck models continue to feature Paccar PX-7 and PX-9 diesel engines, which offer power options ranging from 200 to 380 hp and up to 1,150 lb-ft of torque. The OEM’s only cabover, the Model 220, offers GVW ratings ranging from 26,000 to 33,000 lbs.

Peterbilt says this truck was designed with a low chassis weight to aid high-volume pickup and delivery, as well as beverage and refuse applications. The Model 220 is also available in a right-hand drive configuration for street sweepers and paint striper operations. The OEM’s conventional cab range consists of the Models 325, 330, 337, and 348.

At the top end of Peterbilt’s GVWR offering is the Model 348 truck, which straddles Class 6 and Class 7. Offered in GVW ratings from 33,000 to 66,000 pounds, it’s designed for such specialty applications as crane, construction, utility, and service trucks. Among new features available across several models is Wabco’s OnGuardActive safety system, on Models 348, 337, and 220. This advanced driver assistance system provides acoustic, visual, and haptic alerts in potentially dangerous situations.

The system will also engage the brakes to prevent a collision with a moving or stationary vehicle if the driver does not respond soon enough. The system is always on for vehicle speeds above 15 mph, even when cruise control is disabled. In addition, the OEM says the adaptive cruise control function will help reduce driver fatigue in congested traffic and make cruise control a more useful feature by automatically adjusting vehicle speed relative to the vehicle ahead to maintain a pre-set following distance.
