Trucks and Transportation Sustainability

The transportation industry is changing - now more than ever before - and we're at the forefront

Trucks move over 72% of all freight

transported within the U.S.

36.9 million commercial vehicles, including 4.3 million heavy-duty trucks, move that freight.

Our economy relies on trucking, and our customers rely on us to supply them with innovative products that keep them moving efficiently in an ever-changing landscape.

We are taking

a proactive approach to the changes within the transportation industry.

We're investing in

cutting-edge technology, from new, more efficient engines, to autonomous and zero emissions technology.

We are leading the charge on innovation in the commercial vehicle industry

Proactively Creating Innovative Solutions to Meet Customer Needs

We anticipate our customers' sustainability related challenges

Environmental

Our customers are demanding cutting edge emissions reduction technology; we have been investing and innovating in sustainable technology for many decades

Social

Our customers and their drivers expect their trucks equipped with the latest in safety technology and premium interior accommodations in order to attract and retain the best talent and keep our roads as safe as possible

Commitment to Leading with the World's Cleanest Engine Technology

Over time, we've increased the efficiency of our MX-11 and

MX-13 engines and incorporated environmentally friendly technology. We work tirelessly

to make diesel engine technology as clean as possible.

We continue to innovate as part of our effort to supply customers with practical solutions today and revolutionary solutions tomorrow.

DAF's New Generation XD Electric and XF Electric earned "International Truck of the Year 2026," DAF's third win of this prestigious award in five years.

With the transition to zero emissions technology, we'll continue to lead in engine innovation.

Every PACCAR engine is meticulously designed for maximum uptime, performance and fuel efficiency

PACCAR is Leading the Charge

Zero emissions is a reality at PACCAR

Zero emissions vehicles are growing in popularity in several applications including refuse, port and regional delivery.

We're also exploring hydrogen technology, which is promising for long-haul applications due to its extended range and its relatively fast refueling times.

We began production of battery electric trucks in 2021 and continue fulfilling customer orders for several hundred battery electric vehicles. Our customers are using Kenworth, Peterbilt and DAF zero emissions trucks to haul freight.

As part of the transition to zero emissions, PACCAR has introduced new electric vehicle charging stations to support electric vehicles.

PACCAR is collaborating with Faith Technologies and Schneider Electric to provide charging infrastructure solutions for customers who purchase Kenworth and Peterbilt electric trucks in the US and Canada. Charging power from 20 kW up to 350 kW.

Autonomous Driving

We're investing significantly in autonomous technology with our partners

• PACCAR has invested in a strategic partnership with Aurora to develop, test and commercialize autonomous Peterbilt and Kenworth trucks

• PACCAR's autonomous vehicle platform will be integrated with the Aurora self-driving technologies

• PACCAR customers will benefit from the autonomous vehicles' enhanced safety and operational efficiency

• Kenworth T680 and Peterbilt 579 trucks utilizing the Aurora Driver are expected to be delivered in the next several years

PACCAR and Platform Science Connected Vehicle Partnership

PACCAR has made a strategic investment in Platform Science

• PACCAR and Platform Science will

  collaborate on connected trucks

• PACCAR will integrate the Platform Science Virtual Vehicle into Kenworth and Peterbilt trucks

• The solution enables fleets to access telematics, software solutions, real-time data, and third-party applications directly from their vehicles

• Customers will have access to a customizable platform elevating their capabilities to innovate and utilize, manage and deploy digital applications
