Audi is the first car manufacturer to adopt this environmentally friendly paint application technique in series production.
Using a method known as 'overspray-free painting', Audi is now able to apply two different colours in the same painting process, protecting the environment and cutting costs.
A robot-controlled applicator now allows for two-colour paint finishes to be applied without any masking-off beforehand The new technique is being adopted for the first time for the 'edition one' limited edition models of the A4 Sedan and A5 Sportback, which were updated in 2019, and feature an optional roof finished in brilliant black. Audi is the first car manufacturer to adopt this environmentally friendly technique in series production.
Until now, two-colour paint finishes have inevitably involved two painting processes with masking-off beforehand. Overspray-free painting technology revolutionises this time-consuming and material-intensive process by utilising a robot-controlled high-precision instrument that measures the laser-brazed seam between the car's roof and side panel frame.
An applicator then applies a black paint specially developed for this method onto the body in strips, with millimeter precision but without spray mist. The precision with which the fine strips of paint are applied enables the contrasting paint finish to be created in a single process, saving time and money while also benefiting the environment.
Audi has been testing the new painting process intensively since early 2018 to get it ready for series production. Since mid-2019, it has been possible to create contrasting paint finishes with a black roof within the series production process. The new technology not only reduces the amount of paint used, but also means that masking material is no longer required. This enables Audi to save resources while broadening its customers' scope for customisation.
