AFTER DRIVING MOST OF THE APPROXIMATELY 76,000 MILES COVERED DURING CUMMINS' REDEFINING TOUR, MIKE CARLSON SAID HE'LL NEVER THINK ABOUT FUEL ECONOMY IN QUITE THE SAME WAY.
Hauling just over 60,000 pounds as part of the 36-city tour across North America to demonstrate some of the company’s latest technology, Carlson said he frequently got better than 9 miles per gallon in the tractor-trailer he drove for most of the tour while averaging better than 8 miles-per-gallon over the entire trip.
Trucks on the road today generally get closer to 6 or 7 miles-per-gallon depending on their age, make and model.
“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,” the professional driver with Mobile Events said in the parking lot of Lucas Oil Stadium in downtown Indianapolis, Indiana (USA), where the tour ended Oct. 6, 2015.
The Cummins Redefining Tour, which started in June, featured five Class-8 truck-and-trailer combinations representing major original equipment manufacturer (OEM) brands. The trucks were powered by a combination of Cummins’ current ISX15 engine, the Cummins-Eaton SmartAdvantage Powertrain and the 2017 ISX15 engine with the compact and highly efficient Single Module aftertreatment system.
Fuel economy was only part of the message delivered during the tour – efficiency, performance, reliability and customer support were other key themes. But the tour came as Cummins is exploring ways it can reduce the greenhouse gases (GHGs) produced by its products in use. Improving fuel economy translates directly into GHG reductions.
Several of the technologies featured had fuel-saving components, including ADEPT (Advanced Dynamically Efficient Powertrain Technology), which adjusts speed, power and gear selection to take advantage of vehicle momentum and operate the engine sporadically at idle, maximizing efficiency.
The Redefining Tour served much the same purpose as founder Clessie Cummins’ cross-country forays to demonstrate the attributes of the diesel engine. While not a scientific test, the 2015 tour enabled the company to demonstrate to its customers how Cummins is meeting its mission that everything the company does “leads to a cleaner, healthier, safer environment.”
