Teardrop trailer (truck)
The phrase teardrop trailer has more recently been used to describe a new shape of goods carrying articulated trailer for use with commercial tractor units. The commercial version differs in that the trailer aerodynamics are considered in conjunction with the tractive unit. As such, the "teardrop" phrase refers to the entire combination, not just the trailer.
Initially introduced in 2006, the numbers of teardrop trailers continues to grow in the major commercial fleets; predominantly due to the sharp increase in fuel price and the ever increasing public pressure to reduce CO2 emissions.
Current versions extend up to the legal limit of 13.660 m in length with the capacity to carry 26 pallets (1000x1200 mm) and up to 44 tonnes gross vehicle weight.
The average commercial tractor/trailer travels approximately 60,000 miles (100,000 km) per annum at an average of 8.5 miles per gallon (3.01 km/L). This consumes 33,222 litres of diesel and creates 87 tonnes (87,000 kg) of CO2; creating a huge impact on the environment. The established aerodynamic shape has been suggested to save 10% in fuel in comparison to a flat roof trailer, which will reduce CO2 emissions proportionately (8 tonnes per annum). These claims have been substantiated by a number of independent bodies, including trials carried out at MIRA.
