The world of hybrids is no longer a car and truck field since the debut of big hybrid trucks from manufacturing giants such as Peterbilt, International and Mack. With the introduction of these new vehicles, emissions and diesel consumption has drastically been reduced.
Peterbilt was one of the first companies to offer big hybrid trucks and when they first announced the new technology they offered it in Class 6 and Class 7 models. Class 6 models such as the 320 and 330 have a gross vehicle weight rating of 19,501 to 26,000 lbs and are primarily used for short-haul work. Class 7 vehicles such as the 337 and 348 require a Class B license to operate, have a GVWR of 26,001 to 33,000 lbs and operate in many roles including utility trucks and tow trucks.
As of 2011 Peterbilt expanded the hybrid models to include Class 8 vehicles which require a Class A license to operate. The Class 8 vehicles are better known as Tractor Trailers or Semi trucks and have a GVWR of 33,000 pounds and above. The Peterbilt 386 model is helping owners and operators improve fuel efficiency through aerodynamics and hybrid technology.
Mack trucks are also joining the hybrid revolution and have designed the new TerraPro low end refuse truck. The TerraPro is being operated by New York sanitation drivers who are collecting valuable data which is being used to improve the trucks. Mack and the U.S. Air Force have come together to create a new technology to power hybrid aircraft refueling vehicles. The technology captures braking energy and converts it into electric power which is then stored for later use.
The new technology is expanding beyond the original refuel trucks and is being incorporated into a line of Mack dump trucks. Along with their parent company Volvo, Mack is working to encourage governments to provide tax incentives for privately owned companies. By promoting the new electric drive technology, Mack is helping clean up the environment one truck at a time.
When it comes to a universal design, International has the edge hands down with their DuraStar 4300 hybrid truck. The 4300 is adaptable to any situation, meaning it can take on any role including an ambulance, Utility Boom Arm truck, refuse truck, tow truck and many more. International has cornered the market for medium sized big trucks with the DuraStar 4300 with its endless application possibilities.
Thanks to the innovative hybrid technology used in the International DuraStar 4300, owners are receiving up to 60% savings on annual fuel bills. In roles such as utility vehicles, the DuraStar is reducing fuel costs by up to 40% compared to their diesel powered rivals.
Manufacturers of big hybrid trucks are on the right track and continue to improve on previous designs to help make the world a better place. In addition, owners and operators are reaping the rewards in the form of lower fuel costs and improved emissions which help their pocketbooks along with helping the environment. Time to trade in those old used trucks!
