Ladoux

The proving ground at Ladoux is located at the Michelin Technology Centre, 10 km north of the Michelin head offices in Clermont-Ferrand (in the centre of France).

The site covers 450 ha.

20 test tracks, 45 km long in total, for grip tests on wet or dry surfaces, handling tests, noise tests, comfort, etc.

Logistics: Recharge bay for electric vehicles, wash station, unloading ramp for vehicles, secure buildings

NEW: Michelin has recently equipped its proving ground with High Power Charging systems.

- Modular systems, charging powers available at 175kW

- Additional charging points possibilities in the future

- Suited for current and next generation Evs

- Located nearby the workshops and dry & wet handling tracks
