Normally when it comes to Formula 1, who wins the race is mainly a question of horsepower. But in this case we reckon that the RB13 might have its hands full against a competitor that on paper at least is significantly underpowered.
The Red Bull certainly doesn't look comfortable on that rough terrain, in this publicity shot staged by the team ahead of next weekend's United States Grand Prix.
It will be the sixth time that race has been held at the custom-built Circuit of the Americas in Austin, Texas - the heart of cowboy country. The 20-turn, 3.427 mile (5.513km) track made its first appearance on the F1 calendar in 2012.
The maiden race was won by Lewis Hamilton when he was still with McLaren. Red Bull's Sebastian Vettel took victory in 2013, but since then it's been all Hamilton - and all Mercedes.
Will it be the same again next weekend? Or will Red Bull be able to rustle up something special and round up a thrilling three-horse race alongside Mercedes and Ferrari to enthral the American fans with a duel under the sun to remember?
