Volvo Trucks has introduced new aerodynamic enhancements inspired by aerospace technology, with the goal of minimizing drag during long-haul trips, as well as decreasing fuel consumption and CO₂ emissions. These innovations represent the latest step in advancing Volvo Trucks’ aerodynamics, leveraging techniques already prevalent in aviation and motorsports.
The Volvo FH Aero, which won the 2025 Green Truck Award, acted as a testing platform for these initiatives. Volvo states that this truck merges an efficient powertrain with a longer, streamlined cab design, leading to considerable fuel savings.
Up to 7% Improvement in Fuel Efficiency
The latest features consist of cab airflow stabilizers, extended air deflectors, and redesigned chassis fairings. Volvo claims that these modifications can enhance range, lower emissions, and reduce fuel consumption by as much as 2% when compared to earlier models, contributing to an overall fuel efficiency increase of up to 7% for the Volvo FH Aero.
These enhancements are applicable to the Volvo FH, FH Aero, and FM truck models, covering all types of fuel, including electric, gas, and diesel.
“The extensive time spent on simulations and wind tunnel testing has been worth it. With these new cab modifications, we are adding to the substantial aerodynamic advancements introduced last year, which will be beneficial for our customers,” articulated Jan Hjelmgren, the head of product management at Volvo Trucks.
Integrating Aerospace Techniques into Long-Haul Trucking
The standout upgrade, as noted by Volvo, is the cab airflow stabilizers located on the upper corners next to the windshield. These stabilizers utilize small angled vanes designed to guide airflow accurately.
“We are applying a method typically used in airplanes, Formula One racing, and wind turbine technology,” explained Anders Tenstam, senior technology expert in aerodynamics at Volvo Trucks. “The upper corners of the cab play a pivotal role in aerodynamics. With our new Camera Monitor System, we have leveraged innovative techniques, using tiny vanes to manipulate airflow on a micro scale, resulting in a macro-scale effect.”
Targeted Enhancements for Specific Models
While several upgrades are broadly applicable, the cab airflow stabilizers are exclusive to the Volvo FH and FH Aero models. The FH Aero benefits particularly from its extended cab length of 24 cm (9.4 in.), which reduces air resistance and enhances fuel efficiency on long-haul journeys.
These innovations represent a harmonious blend of industrial design, computational modeling, and practical testing in Volvo Trucks’ advancements in aerodynamics.
