Volvo tests new VNL truck in extreme desert heat

Volvo Trucks is redefining the standards for heavy-duty vehicles by rigorously testing its all-new VNL model in some of the most extreme environments. After surviving the bone-chilling cold of Arctic conditions reaching -40°C in Alaska, the VNL now faces the blistering heat of the desert, reaching temperatures as high as 120°F (48.8°C). This comprehensive testing approach is crucial for ensuring performance and reliability in diverse driving conditions.

This summer, engineers are conducting hot-weather trials in several states, including Arizona, Nevada, and California. These routes are strategically chosen to replicate real-world conditions, featuring steep climbs like the Davis Dam Grade in Arizona, which ascends over 3,500 feet, and the challenging Baker Grade in California’s Mojave Desert, connecting Las Vegas to Los Angeles. Each test is performed with heavy loads, simulating the demanding environments truck drivers face daily.

“Hot weather testing is just as critical as cold weather testing,” emphasized Peter Voorhoeve, president of Volvo Trucks North America. “We are truly putting this truck through a grueling pace of some of the toughest commercial driving conditions possible in the world. From the freezing subzero of Alaska to the extreme heat, our goal is the same – to make sure our customers can count on their Volvo to perform, no matter where they operate.”

rigorous testing under extreme conditions

The testing phase for the VNL involves a variety of scenarios that push the vehicle to its limits. Each test is meticulously designed to evaluate different aspects of the truck's performance and durability:

• Temperature Resilience: Assessing how the truck’s systems perform under extreme heat and load.
• Climbing Grades: Evaluating engine power and efficiency on steep inclines.
• Payload Capacity: Testing the truck’s ability to handle heavy loads safely and efficiently.
• Driver Comfort: Ensuring the cab remains comfortable for drivers even in harsh climates.

By conducting these tests, Volvo aims to ensure that the new VNL model not only meets but exceeds the expectations of truck drivers and fleet operators. Feedback from test drivers is integral to this process, as they log thousands of miles and provide insights on performance, comfort, and reliability.

the “hot shutdown” challenge

One of the most demanding tests in this rigorous evaluation is known as the “hot shutdown.” During this test, trucks are driven up a challenging 10-mile grade in extreme heat, then shut down at the summit. This allows the engine compartment to heat up significantly before descending with a full load, simulating real-world stress conditions.

This method is critical for exposing any potential weak points in the truck’s design under high-temperature conditions. Engineers carefully analyze how the vehicle responds to this extreme heat, ensuring that all systems can withstand the pressure.

innovative features for extreme conditions

Among the features being validated is the Volvo Parking Cooler, a battery-powered system designed to keep the cab cool during rest breaks without the need to idle the engine. This innovation is particularly important for reducing fuel consumption and emissions, which are critical considerations for many fleet operators today.

“Hot-weather testing gives us critical insights into how vehicles respond when everything is working against them,” stated Matthew Taylor, group manager for reliability test engineering at Volvo Group North America. “We want to know exactly how the truck performs when it is essentially being baked from the road up.”

In extreme conditions, air temperatures can reach 115 degrees, while the pavement may exceed 150 degrees, radiating intense heat upward. This not only adds stress to the truck's components but also poses challenges for driver comfort.

importance of driver feedback

Test drivers play a pivotal role in the success of the VNL testing program. Their real-world experiences provide invaluable feedback that influences design refinements. The data gathered from their extensive driving helps identify areas for improvement and enhances overall reliability.

Volvo’s commitment to quality is evident in their approach to this testing phase. By combining quantitative data with qualitative insights from drivers, the team can ensure that the VNL meets the rigorous demands of commercial driving.

future advancements in truck technology

As Volvo continues to innovate, the focus remains on integrating advanced technology to improve vehicle performance. Some key areas of development include:

• Fuel Efficiency: Enhancing engine technology to maximize fuel consumption rates.
• Safety Features: Implementing advanced safety systems to protect drivers and cargo.
• Connectivity: Leveraging telematics for real-time vehicle monitoring and diagnostics.
• Comfort Innovations: Designing cabs with ergonomic features to enhance driver experience.

This multifaceted approach to testing and development ensures that Volvo remains at the forefront of the trucking industry, delivering vehicles that stand up to the toughest demands of the road.
