They may be in the same McLaren-Honda team, but British F1 legend Jenson Button and Spanish racing star Fernando Alonso are fiercely competitive - and this video clip only serves to prove it. Filmed to celebrate the new global partnership between McLaren-Honda and Chandon, the video stars both world champion drivers racing each other across the Chandon winery in the Yarra Valley - but there's not a car to be seen.

Presumably because Chandon weren't prepared to have Formula 1 vehicles tearing up their historic vineyards, Jenson and Alonso race on pushbikes, Segways, motorbikes, tractors and, in one leg, boats instead. "It was great to spend some time in the beautiful Yarra Valley filming the content scenes, it's certainly not a usual way to spend our time in Australia!" Jenson said in a release. It's clear both Jenson and Alonso had a little too much fun during filming - see who wins in the video below.
