On the efficiency drive

With so many messages flying around the trailer world regarding which design is the most fuel-efficient, we've taken a Look at research carried out by MIRA on behalf of Lawrence David to assess what's best for artic aerodynamics.
White the price of fuel may have dropped slightly in recent weeks, there's still no sign of diesel returning to sub-LI-a-litre pump prices any time soon. As a result, all operators are taking a long, hard look at their operations to ensure they've got the right kit for the job.
This is a trend that has not been lost on the trailer-makers, with many stepping up their game on aerodynamics to ensure they've got the most slippy — and as a result, operationally efficient — trailers in the business.
Trailer manufacturer Lawrence David is concerned that operators may be getting blinded by marketing messages and are unable to make decisions based on technical facts. To shed some light on the shadowy areas of trailer aerodynamics, the company recently commissioned automotive research institute MIRA to carry out an in-depth research project (see panel, above). Using the latest computational fluid dynamics (CFD) modelling techniques, MIRA researchers have tested the aerodynamic efficiency of a multitude of trailer variants.
By overlaying this with financial modelling, Lawrence David is able to offer guidance on the likely impact of the operating efficiency of all types of trailer.
Invaluable research
"As well as being instrumental in directing our own product development, this research is invaluable for operators," says Laurence Marshall, managing director at Lawrence David. "Anyone purchasing and operating commercial vehicles is faced with a lot of choices to ensure they are buying the right equipment for the business.
"We've heard a lot of claims from various manufacturers about how their new design is superior. Our research demystifies some of these claims and counter-claims."
