SEAT first rolled out the duo trailer in 2018 in a pilot phase, after testing the giga trailer for the first time two years earlier. The company pioneered the use of both trucks in Spain, in the framework of its firm commitment to sustainable road transport. It expects to open new routes with both trucks in order to take a leap forward in the use of this form of transport.SEAT Vice-president for Production and Logistics Dr. Christian Vollmer stated that “SEAT’s commitment to sustainability and logistics efficiency is a part of our goal of reducing to zero our production impact. Using the duo trailer and the giga trailer for freight transport reduces CO2 emissions by 30%, as well as the number of trucks on the road.”
The duo trailer features two 13.6-metre-long trailers pulled by a truck, with a total length of 31.7 metres and a maximum payload capacity of 70 tonnes. Designed for travelling on high capacity roads, the duo trailer lowers the number of trucks that travel on conventional roads, which is where the highest number of road accidents take place, and enables a 25 per cent decrease in logistics costs. In this sense, six duo trailers take up 36.5% less space on the road compared to six regular lorries. In addition, SEAT is testing new, 520 hp nine-axle trucks that will reduce emissions by 30%, compared to the current 20%.
The giga trailer, the duo trailer’s ‘little brother’, measures 25.25 metres in length and has a maximum payload capacity of 60 tonnes. It consists of two trailers, one measuring 7.8 metres and an additional one that stretches to 13.6 metres pulled by a truck, with a combined maximum payload of 60 tonnes. This truck delivers a 22% savings in logistics costs and lowers CO2 emissions by 14%.
