Aerodynamic Vehicle Features

Aerodynamic enhancements for fuel efficiency

Aerodynamic vehicle features are designed to reduce drag, lower fuel consumption and cut emissions across articulated trailers and rigid bodywork. This section covers Don-Bur aerodynamic developments including Teardrop body profiles, bulkhead deflectors, side skirts and rear airflow devices.

At motorway speeds, aerodynamic resistance is a primary contributor to fuel use. Optimised body shapes and airflow management systems reduce turbulence around the vehicle, improving operational efficiency without compromising payload or structural integrity.

What is included in this category

The content in this section includes both complete body profiles and retrofit components, depending on the feature. Where available, solutions are supported by technical validation, measured performance data and real-world operational feedback.

• Front interface improvements between tractive unit and trailer or cab and body
• Side airflow management and under-run control
• Roofline shaping and body profile optimisation
• Rear wake reduction and pressure recovery

Applications range from long-haul trunking to regional and urban distribution where fuel efficiency, emissions reduction and whole-life operating cost remain key operational considerations.
