Peterbilt displayed its new SuperTruck II demonstrator car for the primary time on the American Trucking Associations’ Administration Convention and Exhibition in San Diego Oct. 23-24. Its radically totally different look drew double-takes, plenty of questions, and folks getting their photos taken by it.
The objective of the Division of Power’s SuperTruck program is to enhance long-haul Class 8 car freight effectivity by way of demonstrating the potential of superior, extremely environment friendly powertrain techniques and car applied sciences.
Peterbilt’s SuperTruck II demonstrator truck was on show at ATA in between testing, with out the customized trailer that can also be a part of the venture. Testing is scheduled to be accomplished by the tip of the 12 months.
The very first thing that jumps out is the truck’s uncommon aerodynamic profile. A middle drive place allowed designers to enhance the power of the aerodynamics to deflect air up and over the truck and trailer, with a particularly curved windshield. The windshield and the near-cabover-like driving place enhance general visibility.
Beneath the tall hood is a Cummins X15 high-efficiency engine and Eaton transmission. A 48-volt delicate hybrid system powers auxiliaries, with electrical energy steering,
HVAC and cooling fan. It additionally places some further energy again into the primary powertrain.
The waste warmth restoration system is way improved from the first-generation SuperTruck, however firm representatives stated it’s most likely nonetheless not one thing that may be commercialized in an economical method.
The cab and chassis use carbon fiber, aluminum, and high-strength metal to take out weight — 4,800 kilos throughout the tractor and trailer mixed. The truck options customized low-rolling-resistance tires and light-weight 24.5-inch wheels.
For aerodynamics, along with smooth, low aero fairings, a wise suspension system will decrease all the tractor-trailer at freeway speeds for the least attainable resistance. The cab extenders use the air system to reshape the extenders to allow them to transfer forwards and backwards to optimize aerodynamics in turns. It additionally makes use of cameras instead of mirrors.
The split-level integral cab and sleeper contains a right-hand entry stand-up door, pop-out home windows, a big, wrap-around sprint, 15” digital sprint show for digital gauges and demanding car knowledge, an extra show for HVAC, infotainment and navigation controls, an articulated seat that rotates left and proper, and a pull-out desk.
