First transmission from Eaton-Cummins joint venture introduced

ATLANTA, Ga. – Eaton Cummins Automated Transmission Technologies took the wraps off the first project produced under its recently-announced joint venture – a new 12-speed automated transmission dubbed Endurant.

The transmission is designed for linehaul applications with gross vehicle weights of up to 110,000 lbs and can manage 1,850 lb.-ft. of torque. Eaton Cummins Automated Transmission Technologies’ representatives also claim the transmission is up to 105 lbs lighter than competitive models. The Endurant was launched at the inaugural North American Commercial Vehicle Show.

“We are excited to introduce our customers to this game-changing transmission,” said Scott Davis, general manager, Eaton Cummins Automated Transmission Technologies. “Fleets will find that Endurant has been intelligently engineered from the ground up with features that protect your investment and make it easy to maintain. With a sophisticated communication system between the engine and transmission software, Endurant promises to deliver industry-best performance and reliability, fuel efficiency, reduced maintenance, and driver comfort features.”

“It is important to note that Endurant is not an automated variant that has been adapted from a manual transmission,” added Gerard DeVito, vice president, Technology, Eaton Vehicle Group. “Endurant was designed, engineered and created from a clean sheet to be an automated transmission, not simply an update to an AMT, allowing us to optimize the transmission’s weight, dimensions and features.”

Davis said the transmission underwent more than two million miles of testing, including in extreme cold. Other features include: an internal electrical system that shields wires from corrosion and potential damage; a new smart prognostics feature that indicates when the clutch will need to be replaced; a new fluid pressure sensor that notifies drivers of low oil levels; smooth and intuitive shift strategies developed to optimize performance with the Cummins X15 engine.

DeVito said the Endurant is a good fit for downspeeding, with its broad range of gear ratios, and provides the lowest cruise rpm in the market. Its ratios also provide excellent low-speed maneuverability, he added.

Davis said the new transmission was developed in close consultation with customers, through three separate customer councils including fleets, drivers, and service managers. “This resulted in a product that hits the mark with customers” he said.

The Endurant also offers the longest oil change intervals, at 750,000 miles – as much as 250,000 to 400,000 miles further than competitive models. And when oil must be changed, only 16 pints is required – about half the amount needed by most AMTs, Davis said. The new transmission will enter production Oct. 16 for Kenworth T680 and Peterbilt 579 models with Cummins X15 engines.

Run on Less trucks hit average of 10.1 mpg during 17-day demonstration

ATLANTA, Ga. – Drivers in the Run on Less demonstration exceeded all expectations and hit an average of 10.1 mpg during the 17-day project.

The North American Council for Freight Efficiency (NACFE) made the announcement on September 24 at the inaugural North American Commercial Vehicle Show in Atlanta, where they proclaimed that “10 mpg is possible with today’s technologies.” 

Run on Less is the first of its kind cross-country road show, where seven drivers drove their regular route for seventeen days, and their fuel mileage was monitored and posted live during the duration of the project. NACFE expected drivers to hit an average of 9 mpg, and in reality, the drivers together hit an average of 10.1 mpg.

“We hosted the Run to demonstrated that with the right investment in technology, and with skilled, ambitious drivers, it is possible to achieve mpg levels far above the average fleet,” Mike Roeth, executive director of NACFE said.

In total all seven drivers, that were hand-selected, drove a total of 50,107 total miles. They saved 2,877 gallons of diesel fuel and $7,193 against the national average of 6.4 mpg. Of the combined days on the road, the highest recorded mpg was 12.8, and three drivers reached more than 12.5 mpg. The average for all of the lowest mpg days during the run was 8.8 – not a far cry from the actual project’s goal of 9 mpg.

“Nine mpg was the goal, so to hear that we not only met but exceed the goal is outstanding,” said Annie Peter from Shell, a sponsor of the demonstration. “It will take collaboration among energy suppliers, lubricant producers and fuel retailers like Shell, vehicle manufacturers, fleet owners, businesses and other organizations to work together to consistently achieve the impressive fuel economy and CO2 reductions these seven drivers accomplished during the Run.”

According to NACFE, these results are staggering when you connect the dots and realize that if the 1.7 million trucks on the North American highways today achieved the same level of efficiency as the truck in Run on Less, they would save 9.7 million gallons of fuel, $23.4 billion, and 98 million tons of carbon dioxide each year.

The trucks participating included three Freightliners, two Internationals, and two Volvos. The drivers were: Henry Albert, Bradley Long, Tommy Revell, Roberto Sandoval, Joel morrow, Clark Reed, and Mark Risien. They faced challenges like Hurricane Irma and Harvey, congestion, and heavy loads. Trucks were equipped with things like automated transmissions, 6×2 axles, tractor and trailer aerodynamics, engine accessories, and tire pressure mentoring systems. The drivers were also experienced and kept an average speed of 54 mph.

One day, a driver even traveled a 3,270-ft. elevation gain with a 72,960-lb gross combination weight and experienced an average of 2.7 mph headwind and still achieved 9.7 mpg.

“We know that equipping these trucks with the technology costs money…but one thing we’ve learned is in the 4-5 years NACFE’s been doing this is there’s a cost of the technology, usually an increase there’s fuel savings, but we’ve found very few times where the total cost of ownership stops there,” Roeth said at the announcement. “So there’s usually other benefits that will help save money. That total picture is what we try to focus on in out work. And that’s what we told the drivers, bring the technology that you have and would want to buy, don’t get them just to get that extra mpg. Bring what you have as a current spec’. We believe these technologies pay back because they’ve procured them.”
