Automotive Doors – New Technology and Trends
Emissions from road transport increased by 26% between 1990 and 2008, with passenger cars currently responsible for 12% of overall EU emissions of CO2 (1). The EU introduced regulations for passenger cars in 2009 with targets for emission levels that manufacturers must adhere to. By 2015 passenger cars should have maximum emissions of 130g CO2/km, with a further target of 95g CO2/km to be achieved by 2020. Limits for the emissions of light commercial vehicles were added to the legislation in 2011, stating that the maximum should be no more than 175g CO2/km by 2017 and 147g CO2/km by 2020.
These targets for reduced emissions are one of the biggest drivers of innovation in the automotive manufacturing sector, with weight reduction at the forefront of development. To meet the regulations each car manufacturer is assessed on the emissions of their overall fleet. Every new car registered is given an indicative emission level based on its mass, and manufacturers must ensure that the average mass of all its cars is in line with the emission allowance. Heavier cars are targeted for greater emissions than lighter cars, so the reduction in the mass of their overall fleet will help manufacturers to comply with the legislation.
The automotive door sector is one area in which manufacturers are looking to reduce overall weight by using alternative materials and new manufacturing concepts. Door suppliers are continually striving to improve the design and engineering of their products, and any reduction in weight will need to be integrated with other areas of innovation such as noise reduction, closure and sealing systems and keyless technology.
