Navistar says it plans to introduce the Navistar 12.7 liter S13 engine platform in the fourth quarter of 2023. The S13 engine is based upon the Scania DC13 engine and will supersede the current 12.4 liter A26 engine platform starting next year. The initial engine installations will be standard on the LT and RH truck platforms and will be introduced to the HV and HX platforms in 2024. The order books are expected to open in October.
The S13 engine will be paired with the new International T14 automated manual transmission. The T14 is a 14 speed AMT which is the first transmission offered by the company.
The current A26 engine platform is based upon the MAN D26 engine platform and will be superseded by the S13 engine over the next few years. Navistar will continue to source the Cummins engine lineup for the foreseeable future. According to Navistar, this will be the last engine upgrade for the company as they plan to focus on zero-emission vehicles. Navistar says that half of all its new vehicles sold by 2030 will be zero-emission; it expects to reach 100% of sales in 2040. PSR
