Inside Hyundai’s secret proving ground

LinkedIn +

Hyundai Motor UK has revealed the development details behind the i30N hot hatch’s dynamic handling, with a special film recorded at its top-secret test track. The footage shows the unique Cacao Corner, featuring a bespoke surface created by Hyundai’s engineers to capture tire prints for dynamic analysis.

The bespoke high viscosity material has been produced at Hyundai’s R&D facility using a selection of abundant natural and completely biodegradable components. Following months of testing, and the combination of hundreds of different ingredients, Hyundai settled on a mixture of just three.

During dynamic testing the i30N completes laps of the test track – including Cacao Corner – and the project engineers analyze the on-board telemetry in conjunction with the tire prints left in Cacao Corner.
