Honda has added a Peterbilt Class 8 diesel-hybrid truck to its fleet as part of the company's ongoing efforts to reduce its fuel consumption.

As part of its on-going effort to reduce its global CO2 footprint and fuel consumption, Honda today became the first company in the industry to introduce a Class 8 hybrid diesel electric truck into its truck fleet at its parts center in Alpharetta, Ga. Built for Honda by Peterbilt Motors Company, the Smartway(SM)-certified Model 386 hybrid truck is expected to reduce carbon dioxide emissions by almost 45 tons per year, as compared to its diesel counterpart.

Hybrid Electric System

Batteries -- One of the key attributes is of the system is the ability to launch all the vehicles under electrical power alone. The success of the Hybrid electric technology is the energy storage system; the lithium-ion batteries. The lithium-ion batteries feature the highest energy density of any available battery technology. In fact, the battery used for this system weighs approximately 110 lbs and is equivalent to 1900 lbs of conventional Pb-Acid units. One of the areas that received attention for 2008 is the redesign and packaging of the hybrid component battery box on all the medium duty products. The redesigned battery box neatly packages the majority of the unique hybrid components in addition to many of the standard items conventionally located in this area. In more detail the redesigned battery box contains the following: hybrid drive cooler, air tanks, conventional 12 volt batteries, and 340 volt DC to AC inverter, and 12 volt converter are all housed in this space conscious enclosure.

Electric Motor -- The Peterbilt electrical hybrid truck features an Eaton Hybrid Electric System. This system features a hybrid drive unit, which includes a 340 volt MGSet, an Eaton Ultrashift transmission and an automatic linear clutch actuator.

The system also improves fuel efficiency and lowers emissions by powering the heating, air conditioning and vehicle electrical systems utilizing a no idle auxiliary power unit while the engine is off.

Honda uses Class 8 trucks to transport service parts between its parts centers and dealerships. The company's diesel truck fleet, operated by its truck fleet partner, UPS Freight Truckload, typically travels 300,000 miles per day.

The hybrid truck will be utilized along two routes-a hilly route in Tennessee and a relatively flat one in Georgia-in order to evaluate the truck's fuel economy under various driving conditions. Honda will alternate the hybrid with a standard diesel truck and will collect data using engine telematics to accurately compare the performance of the two trucks on the same routes. Testing and evaluation will take place over the next year.

"We're excited to add this environmentally advanced truck to our fleet," said Jim Roach, senior vice president of Parts and Service for American Honda. "With our truck fleet driving hundreds of thousands of miles per day, we feel this is a great opportunity for Honda to further reduce its carbon footprint."

The hybrid truck operates much like a hybrid passenger vehicle, utilizing a parallel diesel-electric hybrid system. Similar to Honda's hybrid vehicles, Peterbilt's truck captures energy during braking and stores it in its system's batteries.

Looking forward to seeing the results, from Honda and Walmart. I'm guessing the flat land route will see very modest mpg gains, but the hilly route will show much better. Drivers should notice driveability gains in the hills too. Not having to carry speed into a hill, not going thru downshifts, etc should make it a much nicer drive.

It would be interesting to see what mpg Wayne and Keith could manage with this thing.

I love these incremental moves forward, this experiementation. Good stuff.

Great idea! If they can make these batteries bulletproof in this demanding application, they should be ready for cars soon. Call it a stress test.

Peterbuilt's headquarters is 15 miles north of me in Denton, Texas.

After a decent read, it looks like this is built for Honda, but would love them to also have the rights to it....imagine what Honda could do.

It occurs to me that a conventional car could be designed to have an extra battery pack, regenerative braking, electric AC, electric power steering, electric water pump, and auto-shut off.

Use a 1.2 liter engine with turbo, and you'd have an efficient car, at lower cost than a full hybrid.
