According to Volvo, the enhancements include three key modifications: cab airflow stabilisers, extended air deflectors, and revised chassis fairings. Together, these updates are claimed to improve fuel efficiency by up to 2% on top of the gains already achieved by the existing Aero cab design. The combined effect means the Volvo FH Aero model delivers up to 7% better fuel efficiency compared to the standard Volvo FH it replaced.

The stabilisers, positioned on the upper corners of the cab beside the windscreen, are designed with small oblique vanes to manage airflow around the cab. This addition is made possible by the company’s camera monitor system, which replaces traditional side mirrors and reduces aerodynamic drag.

“The upper corners of the cab are super critical for aerodynamics, and with our new Camera Monitor System, we have been able to access new potentials in this area,” said Anders Tenstam, Senior Technology Expert for Aerodynamics at Volvo Trucks.

The stabilisers also support the function of the extended air deflectors – now 50 mm longer – which reduce the gap between the cab and the trailer, and of the modified chassis fairings that improve alignment with the rear fender. Volvo states that these three features complement each other and deliver a combined benefit greater than the sum of their individual effects.

The new upgrades are available in various combinations across the FH, FH Aero and FM models, though the cab airflow stabilisers are currently limited to the FH and FH Aero. The features are compatible with diesel, gas, and electric powertrains.
Volvo’s 2025 Green Truck Award-winning FH Aero model had already incorporated aerodynamic changes, including a 24 cm extension to the cab, prior to these new additions.
