Jeremy Clarkson, Richard Hammond and James May reluctantly agree to test three SUVs in the rugged landscapes of Canada. Clarkson in the Alfa Romeo Stelvio Quadrifoglio, Hammond in the Porsche Macan Turbo Performance Pack and May in the Range Rover Velar. The boys will test their cars' sporting side at a race track and their utilitarian side with some enormous dogs, before ending in an epic race across the snowy mountains. Also in this show, Jeremy embarks on a legally perilous test of the Tesla Model X. This will mark the first time we've seen him drive a Tesla on-screen since the controversial Roadster review in 2008.
