The Don-Bur Aerodynamic Teardrop™

What is the Teardrop™?

The Teardrop™, first conceived by the Don-Bur design team in 2006, is a unique and innovative commercial vehicle shape that mimics the natural and perfect aerodynamic properties of a liquid teardrop. The streamlined shape generates significant fuel savings and an increase in cubic capacity.

Shape modification of moving vehicles has been proven for some time to improve aerodynamic performance.

In the 1950’s and 60’s, aerodynamics played a crucial role to the design of racing cars, where engineers started to recognise the benefits of higher speed and better stability.

Today, although you may not be consciously aware of it, aerodynamic profiling is commonplace. Modern examples include the Toyota Prius and Honda Insight; both of which have exceptionally low aerodynamic drag. 'Brick'-shaped cars no longer exist except in the garages of the most enthusiastic of collectors.

Sports equipment is also often streamlined to reduce the power-sapping drag and gain improved performance.

Why then, almost a century later, has the proven technology not been used in commercial vehicles?  Why is it that HGV’s continue to be some of the least aerodynamic shapes found on the planet and contribute some of the largest proportions of our countries CO2 emissions?

Goods-carrying vehicles are designed to carry as much load as possible, as efficiently as possible and to withstand the rigours exerted on them by the industry.   Plastic moulding can be prone to damage and shaping of the bodywork can just eat into valuable load space.   In addition, no-one previously considered that aerodynamics would play such a huge role on a vehicle 44 times heavier than its passenger-carrying counterpart.

For those that now own them, Teardrop™ trailers and rigid bodywork proudly stand out amongst the crowd; representing companies that demand better efficiency and care about their impact on the environment…

…companies that are arguably now more attractive to those they supply.

Fuel Savings

Current Average

See case studies



Internal Volume

A standard 4.2m high trailer has 78m3 cubic capacity, compared to a Teardrop™ at 86m3.

There is no effect on load footprint. A standard 13.660m Teardrop™ trailer carries 26 UK pallets.



Impact on CO2 Emissions

CO2 emissions are directly proportional to fuel consumed (2.63kgs CO2 / litre Diesel).

One combination travelling 60,000 miles per annum at 8.5 mpg will consume 32,080 litres of diesel and generate 84.37 tonnes of CO2.

A 10% reduction in fuel use will cut CO2 emissions by 8.4 tonnes.


Key Features & Benefits
