An International project
A BUSY ROLL-OUT OF NEW MODELS FOR THE NORTH American Class 8 truck market is continuing with International Truck announcing its updated LT Series.
Improved aerodynamics, new safety technology and the first application of the Traton Group’s S13 global powertrain in an International model delivers up to 15% better fuel efficiency compared to the first generation International A26 engine.
Fuel efficiency and performance are further improved with an updated aerodynamic package on the LT Series, ideal for line haul applications. This aero package includes Diesel Exhaust Fluid (DEF) and fuel fill closeouts allowing air to flow smoothly over the chassis skirts.
There are also steer wheel closeouts, a modified lower skirt trim improving underbody air flow by restricting air flow through the wheel opening, and a new roof extender improving air flow between the tractor and trailer gap.
The updated front-end design includes a new bumper and grille style that aligns with recent updates to other International truck models. A new premium 9-inch sleeper mattress and flip-up bunk help maximise cab space for over-the-road drivers.
Advanced driver safety enhancements to braking and collision mitigation systems further improve driver safety and comfort. This includes electronic parking brake technology to automatically engage the vehicle and trailer parking brakes if the driver forgets to set them.
The new LT Series can be specified with the International S13 Integrated Powertrain, which is comprised of the 13-litre S13 engine, T14 14-speed automated manual transmission, and Dual Stage Aftertreatment system.
Compared to Navistar’s first-generation International A26 engine specified with the 12-speed overdrive Eaton Endurant HD automated transmission, the new S13 Integrated Powertrain together with the latest updates to the LT Series delivers up to 15% gain in fuel efficiency.
“The International S13 Integrated Powertrain sets an industry standard for efficiency, profitability and sustainability,” said Mathias Carlbaum, chief executive officer. “Not only is it the most efficient powertrain we have ever produced, but it is also a major milestone in our journey to zero-emissions transportation.”
The S13 Integrated Powertrain was designed using a modular system approach. Modular systems allow for mass customisation of broad variant offerings and ensure a long-term competitive advantage. This equates to faster time to market and lower production costs. The Traton Group modular system enables efficient cross-brand development and production, while still allowing for regional adaptation and validation of the S13 Integrated Powertrain for the North American market. This is the first Group-wide demonstration of a modular solution.
The S13 integrated Powertrain is the Navistar branding for what designated in the Traton Group as the CBE (Common Base Engine).
The 13-litre is being introduced into Scania models this year, the Navistar model range in 2023 and MAN from 2024. From 2028 it will also be adopted by Traton’s Brazilian operation, VW Caminhoes e Onibus.
The high-efficiency Euro 6 engine is being touted as the first – and last – jointly deployed large diesel engine for the Volkswagen-owned Traton Group.
Navistar will build the integrated powertrain at its recently expanded Huntsville, Alabama Powertrain Manufacturing Plant.
