The Origin of the Teardrop™ Trailer

In 2006, Don-Bur pioneered the first-ever Teardrop™ aerodynamic trailer, transforming the way trailers cut through the air. Its design was inspired by the natural aerodynamics of a water droplet, a shape proven to minimise drag.

This concept aligns with early automotive innovations like the Tropfenauto ("Teardrop Car"), the world’s first streamlined vehicle. Just as car manufacturers embraced aerodynamics to improve fuel efficiency, Don-Bur applied the same principles to commercial trailers—an industry first.

Designed and manufactured in the UK, the Teardrop™ trailer remains the benchmark for fuel-efficient road transport.

Automotive Aerodynamics Today

For decades, the automotive industry has embraced aerodynamics to improve fuel efficiency. Modern vehicles feature low-drag designs, from streamlined bodywork to underbody fairings, reducing wind resistance and cutting fuel consumption.

Now, these same aerodynamic principles are transforming the commercial vehicle sector. Traditional trailers create significant drag, but aerodynamic trailers—like the Don-Bur Teardrop™—apply proven airflow technology to minimise turbulence, delivering measurable fuel savings and lower CO₂ emissions.

As sustainability targets tighten, aerodynamic design HGVs are becoming the standard for fuel-efficient logistics.

Standard Trailer – High Drag, High Fuel Consumption

Traditional box-shaped trailers create significant aerodynamic drag, increasing fuel consumption and emissions. Their flat front, rear, and top surfaces disrupt airflow, causing turbulence and resistance.

As air moves over the trailer, it forms a vacuum at the rear, pulling the vehicle backward. This effect, combined with high-pressure zones at the front, forces the engine to work harder—leading to higher fuel costs and reduced efficiency.

Teardrop™ Trailer – A True Aerodynamic Trailer

The Don-Bur Teardrop™ is an aerodynamic trailer designed to minimise drag and maximise fuel efficiency. Its curved roofline guides air smoothly over the vehicle, reducing resistance and lowering fuel consumption.

Unlike standard trailers, the Teardrop™ prevents excessive turbulence, allowing for a more efficient attached airflow. This streamlined design requires less energy, delivering proven fuel savings and CO₂ reductions.

Fuel Savings – Proven Performance

On average, operators using the Don-Bur Teardrop™ aerodynamic trailer achieve a verified 11.3% reduction in fuel consumption.

Internal Load Capacity – No Compromise on Space

The Don-Bur Teardrop™ aerodynamic trailer maintains a full load footprint, ensuring no reduction in cargo capacity. A standard 13.6m Teardrop™ trailer accommodates 26 UK pallets, just like a conventional trailer.

To retain a generous rear aperture height, the chassis can be lowered at the rear, allowing the roofline to curve without compromising loading access or internal volume.

Impact on CO₂ Emissions

CO₂ emissions are directly linked to fuel use. Every litre of diesel burned produces 2.63 kg of CO₂.

A standard trailer covering 60,000 miles annually at 8.5 mpg burns 32,080 litres of diesel, emitting 84.37 tonnes of CO₂. A 10% fuel reduction cuts emissions by 8.4 tonnes per vehicle per year.
