Is it a good idea for two 80,000-pound 18-wheelers to tailgate one another? Many states are considering that issue, due to the emergence of technology designed to make trucks safer, coupled with vehicle-to-vehicle communications. These technologies would allow two digitally-connected trucks to follow each other on the road at a closer distance because the electronically-linked trucks accelerate and brake together, bypassing the driver. This electronic pairing of tractor-trailers is called platooning.
Platooning Saves Fuel
Platooning can save money by reducing fuel costs due to “slipstreaming.” When two trucks pair up closely, the air flows more smoothly with less air drag. A truck in the slipstream of another tractor-trailer can save 10 percent on fuel. The truck in front will also burn about 5 percent less fuel. Buying diesel typically amounts to 20 percent of operating costs, which across the industry runs into billions of dollars.
