Eaton and Cummins announced jointly Sunday at the Technology & Maintenance Council (TMC) meeting in Nashville, Tenn., new features to their integrated powertrains that will increase available downspeeding options.
An additional torque rating of 1,850 lb.-ft. for the 400-475 horsepower Cummins ISX15 will be available in April and can be specified with an Eaton Fuller Advantage C-Ratio 10-speed transmission, an Eaton UltraShift PLUS MHP 13-speed transmission or an UltraShift PLUS MXP 18-speed transmission.
“It’s an extension of torque on the top end but it’s also the introduction of SmartTorque2 on the lower end so you get that level of performance,” says Ryan Trzybinski, product strategy manager, Commercial Powertrain, Eaton.
Trzybinski adds the increased capabilities also provide a higher upside for customers in the vehicle’s resale value.
The Advantage transmission has a Gross Commercial Weight (GCW) rating of 110,000 pounds, while the UltraShift PLUS MHP is rated at 140,000 pounds with the MXP having an unlimited GCW rating.
Eaton and Cummins are targeting the release of a SmartAdvantage series transmission with a maximum GCW of 80,000 pounds in August to match with the new 1,850 lb.-ft. torque rating.
Additionally Sunday, Eaton announced its new GearLogic technology, which is integrated with Cummins ADEPT electronic features, and will provide improvements in performance, fuel efficiency and driver confidence.
