LT® Series

BAR RAISED. STANDARD SET.

Introducing the heavy-duty truck all others will be judged by. Operators of the new International® LT® Series equipped with the revolutionary International® S13 Integrated Powertrain may see up to a 15%* gain in fuel economy over the first-generation International® A26. This is one reason why we consider this truck/powertrain combination to be the most business-friendly, profit-expanding, driver-supporting, uptime-boosting Class 8 truck to ever roll down the highway.

Actual customer results may vary due to various factors, including but not limited to, truck specifications, weight of the vehicle, predictive features, environmental conditions, etc.}

ADVANCED. INTEGRATED. UNDISPUTED.

The team behind the International S13 Integrated Powertrain was able to shift what’s possible and rethink, redesign, and reinvent what an integrated powertrain can be. The result is an engine, transmission, and aftertreatment system designed to work as one that’s simple, easy to service, and delivers stellar performance with superior operating economy.

GETTING THE JOB DONE.

Features

Exterior/Mechanical

Hotspots

Cooling Module

The cooling module is sealed to smooth airflow under the hood

Longer Hood

The longer 125” BBC hood better directs and smooths out airflow around the cab.

Cab Extenders

25” cab extenders close the gap between cab and trailer to limit air turbulence.

Pedestal Mirrors

Pedestal mirrors reduce drag and wind noise.

Chassis Skirts and Cab Closeouts

Chassis skirts and cab closeouts have been enhanced to reduce aerodynamic drag.

Fender Shape

Aerodynamic fender shape optimizes airflow.

3-Piece Bumper

An aero-enhanced 3-piece bumper and front wheel openings are contoured to minimize resistance.

LED Headlamps

Long-lasting LED lights improve night vision and polycarbonate lenses resist impacts.

Front Air Dam

The front air dam design reduces drag by efficiently pushing air down, under and around the truck.

Updated Grille

The redesigned grille of the new LT Series with S13 Integrated features a sleek, and refined design that brings a new modern look both owner-operators and fleets will appreciate.

Hood Top and Shoulder

The hood top and shoulder are redesigned to enhance air flow.

Interior

Hotspots

HVAC

Defrost performance is best in class. Vent placement provides excellent airflow throughout the cabin. A more powerful HVAC system provides more heat in winter and more AC in summer. Optional automatic temperature control maintains your designed temperature.

Driver Controls

Driver controls are located by frequency of use, with more frequently used controls located close to the driver. Storage adjacent to the standard USB allows easy charging of personal electronic devices. Four cup and bottle holders quench any thirst.

Premium Cluster

The standard premium cluster features large, easy to read text, collision mitigation information, driver configurable digital gauges, driver alerts, real time fuel economy data, and more.

Visibility

The sloping hood and large side windows provide industry-leading visibility. Door mirrors are large and mounted far forward, improving visibility alongside the vehicle.
