Race car is proving platform for bioresin

RED Motorsport's Lotus Exige completed the third race of the new season on June 14th and 15th, taking place in the Touring Car Championships (TCC) of the Deutscher Motorsport Verband (DMV) at the Hockenheimring. The racing car, which Evonik (Essen, Germany) uses to test new applications, boasts a number of novel features this year including a multilayer line for charge-air cooling.

The green section of the line (see photo) has an outer layer of a biobased polyamide, Vestamid Terra. This is the first time Evonik Industries is testing the multilayer tube system with the biobased plastic on the race track.

Since 2007, Evonik has been testing coolant line systems consisting of multilayer tubes of petroleum-based Vestamid under tough racing conditions. These multilayer tubes serve as lightweight replacements for rubber hoses and reinforced lines. The MLT 8000 multilayer tubing system has since proven its performance in vehicles worldwide. The racing car of the current season uses MLT 8000.3 with an orange outer layer. This system is around 870g lighter than cooling line systems with steelflex tubes, which means a weight reduction of more than 70%....
