Medium-Duty Truck Review: Green Is Clearly the Designer Color for 2009 Models
This story appears in the Sept. 8 print edition of Transport Topics.
However, several truck makers are adding hybrids to their lines.
Navistar International has been in front of this movement. It added the models to its production line offerings this year, followed by Freightliner Trucks, Kenworth Trucks and, most recently, Peterbilt Motors.
This is still a nascent segment, and there is a long way to go before the industry can look on this environmental trend as a permanent growth area, but we may look back on 2009 as a watershed model year, one that could one day lead to similar advancements for heavy-duty trucks.
“For 2009, the door is open to produce all we can build,” said Jim Williams, Navistar’s director of new product sales and distribution.
UPS Inc. this spring ordered 200 hybrid electric chassis from Freightliner Custom Chas-sis, along with another 300 compressed natural gas vehicles.
Kenworth announced that it sold 120 hybrids to Coca-Cola Enterprises. The new trucks will be added to the 20 units that Coca-Cola bought from Navistar in 2007, bringing to 140 the number of medium-duty hybrids in Coca-Cola’s U.S. and Canadian delivery fleet, said spokesman Fred Roselli.
“We’ve seen some pretty significant savings with the hybrids,” Roselli said, including a 37% improvement in fuel efficiency and a 32% reduction in emissions. “And, when they’re idling, the emissions are fewer than that because they use the [electric] motor.” The high initial price — about a minimum 35% premium for a straight truck — is still the biggest deterrent to more sales, manufacturers have said, although current fuel prices certainly help future prospects.
The following article is a review of the 2009 medium-duty (Classes 3-7) truck models.
Dodge
Dodge is staying with power for 2009 with the addition of the 5.7-liter HEMI V-8 gasoline engine (355 horsepower/395 foot-pounds of torque) to the Dodge Ram 3500 (and 2500). Other changes with the 3500 for ’09 include making the 6.7-liter Cummins tur-bodiesel standard, enlarging the front and rear brake rotors, standardizing a limited-slip rear axle and eliminating the manual transmission option with the HEMI.
The Cummins diesel is available with a remote start feature and has 50-state emissions clearance.
Ford Motor Co.
There are few changes in the Super Duty for ’09.
The 6.4-liter Power Stroke V-8 diesel engine is rated at 350 hp and 650 foot-pounds of torque. Gasoline options include the 5.4-liter V-8 (300 hp/365 foot-pounds) or the 6.8-liter V-10 (362 hp/467 foot-pounds).
The factory-built F-450 pickup truck has a maximum towing capacity of more than 24,000 pounds and a maximum payload of more than 6,000 pounds. Ford added a new rear leaf-spring suspension along with the radius arm front suspension from the F-450 chassis cab.
F-650, F-750
The medium-duty line incorporated changes to meet the latest round of diesel emission standards, and there are no significant changes for ’09.
The trucks are available in regular, super or crew-cab configurations as a straight truck or tractor with 38 wheelbase combinations, nine frame strengths, five multileaf and three air suspension systems.
The engine choices include the 6.7-liter Cummins I-6 with several power ratings, stan-dard, or the 7.2-liter I-6 Caterpillar C-7 as an option. The Allison 2000 series automatic transmission series was upgraded.
2008 LCF
There are no significant changes in this Class 4 or 5 low-cab-forward truck. Power win-dows and door locks now are standard features, as are cloth seats.
The only available engine is the 4.5-liter V-6 diesel from Navistar International, rated at 200 hp and 440 foot-pounds of torque. It is matched with the TorqShift automatic.
Freightliner Custom Chassis
The Class 4 MT45 strip chassis carries a GVWR between 14,140 and 19,000 pounds, accepts bodies up to 22 feet and handles payloads up to 10,000 pounds.
The Class 5 MT55 carries a GVWR between 20,500 and 30,000 pounds and handles payloads up to 19,000 pounds and bodies with more than 1,500 cubic feet of volume.
The standard power for both vehicles is the Cummins ISB, rated at 200 hp and 520 foot-pounds of torque. The Allison 1000 or 2100 HS automatic transmissions are standard, depending on the chassis, with various other Allison specs optional.
A vehicle information display monitors engine diagnostics.
Freightliner Trucks
Freightliner introduced the M2 Hybrid with a parallel electric hybrid drive system and offers production units, including a drop-frame beverage model.
The Cummins ISB engine will accept biodiesel formulas up to B20, and an electric-only power take-off option is available.
The core medium-duty Business Class M2 trucks, the 106 and 112, are available with varied vocational options.
The 106 model comes standard with the MBE 900 engine. The 112 comes with GVW ratings up to 66,000 pounds when spec’d for heavier work. The main power is the MBE 4000 engine. Freightliner also offers the Cummins ISB and ISC engines.
General Motors (Chevrolet/GMC)
General Motors added a Class 4 cutaway van with the new 2009 Chevrolet Express and GMC Savana 4500. The 4500 models were designed for school buses, shuttle vans and ambulances, company executives said.
The 4500 Express/Savana is rated at 14,200 pounds gross vehicle weight with a 9,050-pound payload rating.
Power choices include either a 6-liter gasoline engine with variable valve timing, rated at 323 hp, or the 6.6-liter Duramax diesel with 260 hp and 460 foot-pounds of torque.
W-Series
For 2009, the diesel-powered models are 50-state clean-idle certified. The models also have an optional factory-installed limited-slip differential. New cab mounts improve ride quality and driver comfort.
T-Series
These weight Class 6 and 7 tilt-cab models offer Allison Prognostics with the Allison 3000 series automatic transmissions. Allison Prognostics inform the driver when the transmission fluid and/or transmission filter need to be changed.
Kodiak/TopKick
The conventional-style C5500 Kodiak 4x4 has an optional higher GVWR of 21,500 pounds. That model also comes with larger, 70-mm front brake calipers. The 21,500-pound GVWR requires the Allison 2350 6-speed transmission and 19.5-inch wheels.
Allison Prognostics are included on all Allison 3000 and 3500 Series transmissions. The overhead cam Isuzu 5.2-liter 4HK1-TC turbocharged, intercooled, diesel engine (205 hp, 441 foot-pounds) is standard in the W-Series.
The Isuzu 6H diesel engine — the base diesel engine in all Class 6-8 models — is available with five different power ratings and 560 to 860 foot-pounds of torque.
Hino Trucks
Hino introduced two models for city refuse and sweeper applications.
A sit-down, dual-drive model has dual driving stations and curbside visibility. In addition, a stand-up, right-drive model also is available.
Other recent changes Hino is offering include the addition of exhaust brakes, aluminum fuel tanks, powder-coated wheels and programmable idle shut-down as standard features.
The Allison 2500RDS automatic transmission is available with the 268A model and the Eaton UltraShift will be offered as a midyear option with the 268A and 338 models, the company said.
Isuzu Commercial Truck of America
Isuzu focused on its best-selling N-Series models for ’09. The front suspensions, spring rates, steering and cab mount bushings have been tuned to offer a better ride. A limited slip differential is now optional, and an electronic braking distribution system adjusts to the load weight distribution and automatically balances brake pressure to all wheels. All diesel trucks are 50-state clean-idle certified.
The diesel versions use the Isuzu 5.2-liter 4H turbo engine (205 hp, 441 foot-pounds). The gasoline models use the GM-built Vortec 6-liter V-8 (325 hp, 360 foot-pounds) standard with the 4-speed automatic.
Kenworth Truck Co.
Kenworth introduced the Class 6 T270 and Class 7 T370 production model hybrid trucks. The trucks are powered by the Paccar PX-6 engine and, as with the other hybrids, the Eaton 6-speed UltraShift automated mechanical transmission. The trucks also can be spec’d with an electric PTO, which can draw on the 340-volt lithium-ion battery pack for engine-off operation.
There are no substantial changes in the standard models. The T270 is rated at 26,000 pounds and is available as a straight truck. The T370 is available as either a straight truck or tractor. Both are powered by the PX-6 with either Eaton manual or Allison automatic transmissions.
Mitsubishi Fuso
Mitsubishi’s lightest unit is the Class 3 FE125 with a 12,500-pound GVW rating, but it uses the same basic chassis and cab configuration as its heavier-duty Class 4 and Class 5 siblings.
The FE125, Class 4 FE145 (14,500 pounds GVWR) and Class 5 FE180 (17,995 pounds GVWR) are available with an Aisin electronic 6-speed overdrive automatic transmission standard.
Fuso is discontinuing the heavier, Class 6 and 7 FK models after the ’09 model year.
Navistar International
Navistar’s International group was the first to begin line production of hybrid commercial trucks, using the DuraStar model. Navistar has added an optional integrated telematics system — AWARE Vehicle Intelligence — to the truck’s onboard multiplex communication system, Diamond Logic. The system integrates wireless communication, vehicle-monitoring systems and GPS.
However, neither the conventional DuraStar nor the low-cab-forward CityStar models have significant metal changes for 2009. The DuraStar models are powered by the Maxxforce 9 or Maxxforce DT engines, with ratings up to 330 hp and 950 foot-pounds of torque. Transmissions include the Eaton Fuller 6-, 7- or 10-speed manuals and Allison automatics. The Classes 4 and 5 CityStar comes with the Maxxforce 5, a 4.5-liter V-6 diesel engine (200 hp/440 foot-pounds).
Peterbilt Motors
Peterbilt’s two midrange diesel electric hybrid trucks — the Class 6 model 330 HE and Class 7 335 HE — are now available as production-line models. The trucks use either Paccar’s PX-6 or PX-8 diesel engines with Eaton’s hybrid system.
The trucks provide up to 40% improvement in fuel economy, depending on the configuration, the company said. In applications with additional power equipment needs, such as utilities with aerial devices, the lithium-ion battery pack powers the equipment with the engine off, and that application can increase fuel efficiency.
Other midrange models have not changed significantly. The 330 and 335 are Peterbilt’s foundation medium-duty (Classes 6 and 7, respectively) models. The trucks use either Paccar’s PX-6 or PX-8 diesels, Cummins-built models with ratings up to 330 hp, depending on the specs.
Peterbilt introduced the 325, a Class 5 conventional truck designed for drivers without CDLs.
The Class 6 non-CDL 210 (26,000 pounds GVWR) and the CDL-required Class 7 220 (33,000 pounds GVWR) are Peterbilt’s LCF models. Both use the PX-6 engine.
Sterling Trucks
Sterling introduced the natural gas-powered Set-Back 113 medium- and heavy-duty tractor this spring. The truck is powered by the Cummins Westport ISL G, which meets 2010 emission standards.
Acterra
The Acterra, Sterling’s midrange (Classes 5-7) truck, uses the Cummins ISB as standard power. The Mercedes-Benz MBE 900 is a common option for most applications, while the Cummins ISC, with ratings up to 350 hp for fire, emergency or recreational vehicle applications, is also available.
360
The 360 is a rebadged version of the Mitsubishi Fuso F-Series truck. The 360 is available in GVW ratings from 12,500 to 19,500 pounds. The truck is powered by a 4-cylinder Mitsubishi diesel rated at 185 hp and matched with an Aisin 6-speed automatic transmission.
Bullet
The Bullet is a rebadged Dodge Ram chassis cab, an arrangement made when both truck makers were part of DaimlerChrysler. The truck is available as a regular or quad cab with 4x2 or 4x4 drivelines. It has a maximum GVW rating of 19,500 pounds.
UD/Nissan Diesel
All ’09 model-year trucks are clean idle certified for California and other states with idling limits.
The 2600, 2600LP and 3300 models with Allison automatic transmissions are available with a rear-engine PTO. The Classes 6 and 7 models also will offer rear air-ride suspensions with a dash-mounted pressure release switch.
Workhorse Custom Chassis
Workhorse, a subsidiary of Navistar, offers gasoline- and diesel-powered strip chassis for the commercial sector.
There are no major changes for 2009. Forward chassis supports were added to reduce frame rail movement, and reinforced frame cross members and component supports are now standard.
The W42 gasoline model carries a standard GVW rating of 9,400 pounds. The diesel version’s standard rating is 14,500 pounds.
The W62 version — also available as gas or diesel — has a 19,500-pound standard GVWR.
The color for 2009 medium- and light-duty trucks is green, as in environmentally friendly. There are no major changes to designs for the 2009 model year; like heavy-duty trucks, the next major changes will occur with the 2010 model year as manufacturers adapt to the next round of diesel emission standards.
However, several truck makers are adding hybrids to their lines.
Navistar International has been in front of this movement. It added the models to its production line offerings this year, followed by Freightliner Trucks, Kenworth Trucks and, most recently, Peterbilt Motors.

Peterbilt’s two midrange diesel electric hybrid trucks — the Class 6 model 330 HE and Class 7 335 HE — are now available as production-line models. The trucks use either Paccar’s PX-6 or PX-8 diesel engines with Eaton’s hybrid system.
The trucks provide up to 40% improvement in fuel economy, depending on the configuration, the company said. In applications with additional power equipment needs, such as utilities with aerial devices, the lithium-ion battery pack powers the equipment with the engine off, and that application can increase fuel efficiency.
Other midrange models have not changed significantly. The 330 and 335 are Peterbilt’s foundation medium-duty (Classes 6 and 7, respectively) models. The trucks use either Paccar’s PX-6 or PX-8 diesels, Cummins-built models with ratings up to 330 hp, depending on the specs.
Peterbilt introduced the 325, a Class 5 conventional truck designed for drivers without CDLs.
The Class 6 non-CDL 210 (26,000 pounds GVWR) and the CDL-required Class 7 220 (33,000 pounds GVWR) are Peterbilt’s LCF models. Both use the PX-6 engine.
Sterling Trucks
Sterling introduced the natural gas-powered Set-Back 113 medium- and heavy-duty tractor this spring. The truck is powered by the Cummins Westport ISL G, which meets 2010 emission standards.
Acterra
The Acterra, Sterling’s midrange (Classes 5-7) truck, uses the Cummins ISB as standard power. The Mercedes-Benz MBE 900 is a common option for most applications, while the Cummins ISC, with ratings up to 350 hp for fire, emergency or recreational vehicle applications, is also available.
360
The 360 is a rebadged version of the Mitsubishi Fuso F-Series truck. The 360 is available in GVW ratings from 12,500 to 19,500 pounds. The truck is powered by a 4-cylinder Mitsubishi diesel rated at 185 hp and matched with an Aisin 6-speed automatic transmission.
Bullet
The Bullet is a rebadged Dodge Ram chassis cab, an arrangement made when both truck makers were part of DaimlerChrysler. The truck is available as a regular or quad cab with 4x2 or 4x4 drivelines. It has a maximum GVW rating of 19,500 pounds.
UD/Nissan Diesel
All ’09 model-year trucks are clean idle certified for California and other states with idling limits.
The 2600, 2600LP and 3300 models with Allison automatic transmissions are available with a rear-engine PTO. The Classes 6 and 7 models also will offer rear air-ride suspensions with a dash-mounted pressure release switch.
Workhorse Custom Chassis
Workhorse, a subsidiary of Navistar, offers gasoline- and diesel-powered strip chassis for the commercial sector.
There are no major changes for 2009. Forward chassis supports were added to reduce frame rail movement, and reinforced frame cross members and component supports are now standard.
The W42 gasoline model carries a standard GVW rating of 9,400 pounds. The diesel version’s standard rating is 14,500 pounds.
The W62 version — also available as gas or diesel — has a 19,500-pound standard GVWR.
The color for 2009 medium- and light-duty trucks is green, as in environmentally friendly. There are no major changes to designs for the 2009 model year; like heavy-duty trucks, the next major changes will occur with the 2010 model year as manufacturers adapt to the next round of diesel emission standards.
However, several truck makers are adding hybrids to their lines.
Navistar International has been in front of this movement. It added the models to its production line offerings this year, followed by Freightliner Trucks, Kenworth Trucks and, most recently, Peterbilt Motors.
This is still a nascent segment, and there is a long way to go before the industry can look on this environmental trend as a permanent growth area, but we may look back on 2009 as a watershed model year, one that could one day lead to similar advancements for heavy-duty trucks.
“For 2009, the door is open to produce all we can build,” said Jim Williams, Navistar’s director of new product sales and distribution.
UPS Inc. this spring ordered 200 hybrid electric chassis from Freightliner Custom Chassis, along with another 300 compressed natural gas vehicles.
Kenworth announced that it sold 120 hybrids to Coca-Cola Enterprises. The new trucks will be added to the 20 units that Coca-Cola bought from Navistar in 2007, bringing to 140 the number of medium-duty hybrids in Coca-Cola’s U.S. and Canadian delivery fleet, said spokesman Fred Roselli.
“We’ve seen some pretty significant savings with the hybrids,” Roselli said, including a 37% improvement in fuel efficiency and a 32% reduction in emissions. “And, when they’re idling, the emissions are fewer than that because they use the [electric] motor.” The high initial price — about a minimum 35% premium for a straight truck — is still the biggest deterrent to more sales, manufacturers have said, although current fuel prices certainly help future prospects.
The following article is a review of the 2009 medium-duty (Classes 3-7) truck models.
Dodge
Dodge is staying with power for 2009 with the addition of the 5.7-liter HEMI V-8 gasoline engine (355 horsepower/395 foot-pounds of torque) to the Dodge Ram 3500 (and 2500). Other changes with the 3500 for ’09 include making the 6.7-liter Cummins turbodiesel standard, enlarging the front and rear brake rotors, standardizing a limited-slip rear axle and eliminating the manual transmission option with the HEMI.
The Cummins diesel is available with a remote start feature and has 50-state emissions clearance.
Ford Motor Co.
There are few changes in the Super Duty for ’09.
The 6.4-liter Power Stroke V-8 diesel engine is rated at 350 hp and 650 foot-pounds of torque. Gasoline options include the 5.4-liter V-8 (300 hp/365 foot-pounds) or the 6.8-liter V-10 (362 hp/467 foot-pounds).
The factory-built F-450 pickup truck has a maximum towing capacity of more than 24,000 pounds and a maximum payload of more than 6,000 pounds. Ford added a new rear leaf-spring suspension along with the radius arm front suspension from the F-450 chassis cab.
F-650, F-750
The medium-duty line incorporated changes to meet the latest round of diesel emission standards, and there are no significant changes for ’09.
The trucks are available in regular, super or crew-cab configurations as a straight truck or tractor with 38 wheelbase combinations, nine frame strengths, five multileaf and three air suspension systems.
The engine choices include the 6.7-liter Cummins I-6 with several power ratings, standard, or the 7.2-liter I-6 Caterpillar C-7 as an option. The Allison 2000 series automatic transmission series was upgraded.
2008 LCF
There are no significant changes in this Class 4 or 5 low-cab-forward truck. Power windows and door locks now are standard features, as are cloth seats.
The only available engine is the 4.5-liter V-6 diesel from Navistar International, rated at 200 hp and 440 foot-pounds of torque. It is matched with the TorqShift automatic.
Freightliner Custom Chassis
The Class 4 MT45 strip chassis carries a GVWR between 14,140 and 19,000 pounds, accepts bodies up to 22 feet and handles payloads up to 10,000 pounds.
The Class 5 MT55 carries a GVWR between 20,500 and 30,000 pounds and handles payloads up to 19,000 pounds and bodies with more than 1,500 cubic feet of volume.
The standard power for both vehicles is the Cummins ISB, rated at 200 hp and 520 foot-pounds of torque. The Allison 1000 or 2100 HS automatic transmissions are standard, depending on the chassis, with various other Allison specs optional.
A vehicle information display monitors engine diagnostics.
Freightliner Trucks
Freightliner introduced the M2 Hybrid with a parallel electric hybrid drive system and offers production units, including a drop-frame beverage model.
The Cummins ISB engine will accept biodiesel formulas up to B20, and an electric-only power take-off option is available.
The core medium-duty Business Class M2 trucks, the 106 and 112, are available with varied vocational options.
The 106 model comes standard with the MBE 900 engine. The 112 comes with GVW ratings up to 66,000 pounds when spec’d for heavier work. The main power is the MBE 4000 engine. Freightliner also offers the Cummins ISB and ISC engines.
General Motors (Chevrolet/GMC)
General Motors added a Class 4 cutaway van with the new 2009 Chevrolet Express and GMC Savana 4500. The 4500 models were designed for school buses, shuttle vans and ambulances, company executives said.
The 4500 Express/Savana is rated at 14,200 pounds gross vehicle weight with a 9,050-pound payload rating.
Power choices include either a 6-liter gasoline engine with variable valve timing, rated at 323 hp, or the 6.6-liter Duramax diesel with 260 hp and 460 foot-pounds of torque.
W-Series
For 2009, the diesel-powered models are 50-state clean-idle certified. The models also have an optional factory-installed limited-slip differential. New cab mounts improve ride quality and driver comfort.
T-Series
These weight Class 6 and 7 tilt-cab models offer Allison Prognostics with the Allison 3000 series automatic transmissions. Allison Prognostics inform the driver when the transmission fluid and/or transmission filter need to be changed.
Kodiak/TopKick
The conventional-style C5500 Kodiak 4x4 has an optional higher GVWR of 21,500 pounds. That model also comes with larger, 70-mm front brake calipers. The 21,500-pound GVWR requires the Allison 2350 6-speed transmission and 19.5-inch wheels.
Allison Prognostics are included on all Allison 3000 and 3500 Series transmissions. The overhead cam Isuzu 5.2-liter 4HK1-TC turbocharged, intercooled, diesel engine (205 hp, 441 foot-pounds) is standard in the W-Series.
The Isuzu 6H diesel engine — the base diesel engine in all Class 6-8 models — is available with five different power ratings and 560 to 860 foot-pounds of torque.
Hino Trucks
Hino introduced two models for city refuse and sweeper applications.
