Spoiler alert: Pommier launches lightweight aerodynamic kits09 March 2020

Commercial vehicle bodywork equipment supplier Pommier has announced a new range of aerodynamic rear spoiler kits.

Called Airwin, the patented kits are supplied ready to mount on rear doors and weigh less than 20kg per spoiler in the standard version.

Based on an offset rear spoiler, Airwin reduces the suction effect around the rear doors. The spoilers act as shrouds, which force part of the airflow to compensate for the aerodynamic pressure drop generated by the vehicle and reduce its drag.

The technique is already used in motor racing, and allows the length of rear spoilers to be halved, while maintaining the same efficiency in terms of improved fuel consumption.

Pommier says Airwin reduces fuel consumption by 2.5% – around 0.7 litres for a vehicle with average consumption of 27 litres per 100km – and offers a rapid ROI for vehicles covering long distances on motorways and/or at high speeds (above 75kph). For vehicles covering 150,000km a year, says the supplier, ROI will be less than two years.

The kits are intended for dry vehicle bodies (vans and curtainsided vehicles) but can also be installed on refrigerated bodies. The range, which comprises two versions for different door heights, is now available and can be mounted on the majority of trailers, semi-trailers and truck-type vehicles.

Airwin is fully compliant with aerodynamic device regulations: it is designed to have a rear spoiler overhang of less than 200mm, so can be left in the road position in all conditions, including in urban areas. The product also allows for an optimum door opening angle of 265° for easy access at loading docks.
