- Enjoy the greatest cars of the world, on the greatest roads of the world with Sixt Rent a Car. The Col de la Bonette is a wonderful route through an amazing landscape. This journey takes us from the south up towards the top and the loop around Cime de la Bonette at 2,802 m (9,193 ft). The car is an Audi A4 S Line 2017 edition and this recording was made in September 2017. Thank you for watching and enjoy!
