Cummins wraps up 76,000-mile fuel-efficiency demo
"If you had told me I'd be getting 8.3 or 8.4 miles per gallon when we started this trip, I'd say that's impossible," driver Mike Carlson said. "This trip has completely changed my perspective on fuel economy."
Most freight trucks get closer to 6 or 7 miles per gallon, the company said.
The trucks carried a load of about 60,000 pounds that was used to demonstrate Cummins technology at trade shows along the route. The trucks' energy-saving combo of components included the current ISX15 engine, the Cummins Eaton SmartAdvantage Powertrain, and the 2017 ISX15 engine with a single module, after-treatment system.
Despite this modern equipment, the tour also hearkened back to similar ones led by the company's founder, Clessie Cummins, during the 1920s and 30s, Vice President of North American Engine Business Amy Boerger said Cummins once drove coast to coast for under $12 in gas, with similar intentions of connecting with customers and proving economy.
The more fuel-efficient designs are part of an ongoing effort by Cummins to lower the overall greenhouse gas production of its equipment.
