It’s not often drivers are given permission to take part in events outside of F1, particularly rallying which carries a high risk factor.
In 2011, Robert Kubica took part in a rallying event and suffered near-fatal injuries which ruled him out of F1 for several years – the Pole is set to make his competitive return with Williams this season after an eight-year break.
Bottas though is excited ahead of his debut: “This is a unique opportunity to take a peek into the world of rallying, and I would like to thank everyone who has made it possible.
“It’s totally new territory for me too, as I have no prior experience of a World Rally Car. Still, being the race car driver that I am, you always go flat out whatever the vehicle you’re driving in.”
