Detroit has enhanced its DD15 engine and has expanded the lineup of its DT12 automated manual transmission.
The DT12 transmission has evolved into the DT12 On-Highway Series to offer three purpose-built options to meet the unique needs of various on-highway applications, all of which are now available to order, Detroit says. Engineered with fuel efficiency and performance in mind, the new DT12-HE debuts with enhanced features and capability, the company adds.
The Detroit DT12-HE transmission is a new DT12 option which Detroit says boasts higher overall ratios for improved downspeeding and an improved oil system design, both contributing to increased efficiency. The DT12-HE debuts with Freightliner Cascadia production beginning in early 2021 and additional model applications will be announced soon.
Also included in the DT12 On-Highway Series is the DT12-HL transmission, a lightweight carry-over option offering comparable efficiency and durability to the rest of the portfolio and intended for weight-sensitive applications. Lastly, Detroit says the DT12-H retains the same characteristics of the DT12. Both the DT12-H and DT12-HL are currently available for order in Cascadia builds.
The DD15 Gen 5 engine has been completely updated and will be available with January 2021 truck builds. The Gen 5 advances Detroit’s heavy-duty engine platform (HDEP).
