Big serious trucks are not usually what comes to mind when you think of the word "hybrid" but in a world of $100+ barrels of light sweet crude, Peterbilt is putting out some products that may change that. Its medium duty Model 330 (photo above) is just like a Prius. Except it takes diesel and boasts as much torque as a herd of Prii.

Featuring the Eaton parallel hybrid power system, the Model 330 and Model 335 both offer electric motor assist, regenerative braking, lithium ion batteries and fat tax credits. The 330 uses about 30 percent less fuel in an urban driving cycle while the 335 can save a whopping 60 percent when it's used in a utility configuration. How does it do that? Say you're up in the bucket rescuing a kitten restoring power after a thunderstorm, the battery supplies the juice you need to maneuver. If you need more than the battery has, the motor will automatically turn on and quickly recharge it.

Peterbilt has another type of truck that features Eaton's Hydraulic Launch Assist (HLA). The imaginatively-named Model 320 is designed for "vocational stop-and-go applications" or "garbage truck," in the modern parlance. As a vehicle that may stop and go a thousand or more times a day, this Peterbilt takes advantage of hydraulics to recover up to 75 percent of the energy from stopping to use for relaunching.

As has been found with other heavy duty hybrids, maintenance, as well as fuel, savings are significant with these workhorses. Quieter operation and lower environmental impact seal the deal. Check out all the details in the press releases after the jump.

Press release for Model 330 and Model 335

Mar 26 2008
PETERBILT ANNOUNCES FULL PRODUCTION OF MEDIUM DUTY HYBRID ELECTRIC VEHICLES
LOUISVILLE, Kentucky (March 26, 2008) – Peterbilt Motors Company announced plans for full production of its Model 330 and Model 335 medium duty hybrid vehicles during its press conference at the 2008 Mid-America Trucking Show. The vehicles will be in full production at its manufacturing facility in Ste. Therese, Quebec, Canada in summer 2008.

Both the Peterbilt Model 330 and Model 335 Hybrid Electric vehicles feature the Eaton Hybrid Power system and provide customers with impressive fuel savings benefits. The Model 330 utilizes components that provide up to a 30 percent improvement in fuel economy in an urban driving cycle. The Model 335 Hybrid Electric utilizes these same components to provide up to a 60 percent improvement in overall fuel efficiency, when configured for utility applications. The Model 330 Hybrid Electric can be configured for non-CDL operation with hydraulic brakes for a greater range of driver options.

Additionally, the Model 330 and Model 335 hybrids are eligible to receive tax credits from the United States Federal Government as certified by the Department of Treasury's Heavy Manufacturing and Transportation Group. The maximum $12,000 credit for Class 7 hybrids is available for the Model 335 Hybrid Electric in both utility-boom and pickup and delivery applications. A $6,000 credit, the maximum for Class 6 hybrids, is available for the Model 330 Class 6 Hybrid Electric.

"With higher fuel costs and growing concerns with the global carbon footprint, Peterbilt is at the forefront in the development of green technologies that help the environment by providing greater fuel savings and reducing emissions," says Bill Jackson, Peterbilt General Manager and PACCAR Vice President. "Our medium duty hybrid vehicles have been proven in testing across North America to demonstrate impressive fuel efficiency improvements."

Medium Duty Hybrid Electric Vehicles

Both trucks use a parallel hybrid system with an electric motor that assists the diesel engine with supplemental torque for improved fuel economy. The system stores energy during stopping through a process called regenerative braking, and then reuses it to launch and accelerate the vehicle.

The Class 6 Model 330 is powered by the PACCAR PX-6 engine rated at 260 horsepower and 620 ft-lbs of torque. With the hybrid system engaged, horsepower increases to 300 and torque is limited to 860 ft-lbs. This configuration is ideal for stop-and-go use, such as urban pickup and delivery, resulting in up to a 30 percent fuel savings.

Peterbilt's Class 7 Model 335 uses the hybrid electric system for both on-road driving and stationary PTO applications. Also powered by the PACCAR PX-6 engine, it uses the system's lithium-ion batteries to electrically operate the PTO. During bucket operation, the engine needs to run only about 1/6th of the time, versus non-hybrid vehicles. The engine then automatically starts to recharge the batteries, which takes approximately 4.5 minutes, and then shuts off. Fuel use, emissions and noise are greatly reduced when used in municipal and utility applications.

Maintenance requirements are also reduced from the regeneration reducing brake wear, as well as less wear and tear on the engine.

Peterbilt Motors Company, a division of PACCAR Inc (Nasdaq: PCAR), manufactures premium quality trucks for a wide range of markets, including over-the-road, construction, municipal and medium duty.

Press release for Model 320

Mar 26 2008 PETERBILT ANNOUNCES PRODUCTION OF ITS HYBRID MODEL 320 HYDRAULIC LAUNCH ASSIST VEHICLE
LOUISVILLE, Kentucky (March 26, 2007) – Peterbilt Motors Company announced its plan for full production of the hybrid Model 320 Hydraulic Launch Assist (HLA) vehicle in the fourth quarter of 2008 during its press conference at the 2008 Mid-America Trucking Show.
Peterbilt's low-cab-forward Model 320 Hydraulic Hybrid, for vocational stop-and-go applications such as refuse collection, utilizes HLA technology developed by Eaton Corporation exclusively for PACCAR. The system captures the trucks kinetic energy during braking to assist in launching and accelerating the vehicle. Testing has proven a significant improvement in fuel economy, and indicated the potential to reduce annual brake re-alignment services by 50 percent annually.

"The Model 320 HLA is an ideal environmental option for refuse applications," says Bill Jackson, Peterbilt General Manager and PACCAR Vice President. "Dramatic improvements in fuel economy, reductions in emissions and lower maintenance costs spotlight the Peterbilt Model 320 Hydraulic Hybrid as the environmentally responsible, fuel-efficient solution for municipal and residential solid waste transportation fleets. These fleets operate in some of the most demanding of truck applications, often making 800-1200 stops per day on collection routes."
Hydraulic Launch Assist technology works by recovering up to 75 percent of the energy normally lost as heat by the vehicle's brakes in the form of pressurized hydraulic fluid. This fluid is stored in an on-board accumulator until the driver next accelerates the vehicle.
In "fuel economy mode," savings occur when stored energy is used to launch the vehicle followed seamlessly by power from the primary engine. In "performance mode," the stored energy is released and blended with engine power at launch. Here, a double-digit savings in fuel economy can still be realized, along with an 18 percent improvement in acceleration.
