Futuristic ‘SuperTruck’ doubles the MPG of different semis
The EPA estimates that motor automobiles contribute about half of America’s smog-forming risky natural compounds and nitrogen oxide emissions yearly. And provided that the typical gasoline effectivity of your common 18-wheeler solely hits about 6 miles per gallon, these massive rigs could be massive polluters too. However this new prototype from Daimler Vans North America, constructed as a part of the US Division of Transportation’s SuperTruck Problem, sips simply half as a lot fuel.
When the DOT began the SuperTruck Problem in 2009, organizers hoped to see a 50 % effectivity improve over that yr’s “common” semi. Daimler’s “Freightliner SuperTruck” greater than doubled that objective, boasting a one hundred fifteen % improve over the baseline commonplace. Most of that enchancment comes from easy aerodynamic tweaks like including an adjustable experience peak, rear wheel fairings and articulated aspect extenders to cowl gaps between the cab and trailer. The SuperTruck can also be seven hundred kilos lighter than the baseline, because of a reengineered tractor body.
What’s extra, its hybrid diesel/electrical 10.7-liter energy plant dietary supplements the diesel gasoline supply with recaptured waste warmth from the exhaust and brake. Roof-mounted photo voltaic panels attract sufficient power to independently run the trailer’s air con system on sunny days. The SuperTruck even leverages GPS monitoring to mechanically shift gears and modulate the car’s velocity to maximise effectivity given upcoming terrain modifications. All this interprets into one significantly environment friendly car — at the least as far 18-wheelers go. A current check run by means of Texas noticed the Freightliner hit 12.2 miles per gallon at sixty five miles per hour. That is not dangerous for a truck pulling greater than sixty five,000 kilos.
