Damler participates in The US Department of Energy’s SuperTruck program. They unveiled an exciting concept truck. The truck includes some really intelligent features such as:
- Resultant aerodynamic efficiency enables it to run a downsized 10.7L diesel engine, which reduces its fuel consumption.
- Solar panels mounted to the trailer’s roof which can power the climate control system among other things.
- Waste heat recovery system connected to exhaust that converts thermal energy otherwise wasted.
- Powertrain that selects the right gears to optimize battery regeneration and improve efficiency
During the 312-mile Texas highway drive, the truck averaged 12.2 mpg while cruising with a gross weight of 65,000 pounds at an average 65 mph between San Antonio and Dallas.
The numbers listed above, on the surface might not seem impressive, but when you realize that freight trucks make up only 4% of vehicles on the road and use 20% of fleet fuel consumption, it is very impressive. Damler also achieved the fuel efficiency numbers using commercially available technologies. This means most manufacturers can achieve the same goals.
Current Federal regulations require heavy-duty trucks to achieve a 10- to 20-percent increase in fuel efficiency by 2018.
These fuel standards seem very acheivable as proved by Damler. This SuperTruck more than doubled the average fuel efficiency of today’s commercially available semis. Read more…
