This week sees Jeremy Clarkson, Richard Hammond and James May arrive with their travelling tent in Nashville, Tennessee – and warm the audience up with a bit of Trump-baiting.

The Trump tirade emerges as Clarkson greets the residents of the city, saying how it was named after General Nash – a prominent figure in the War of Independence. Describing Nash, he says “War hero, kicked the British out, you got independence and how’s that working out for you?” to the amusement of the audience.

Among the other exploits featured this week are the trio’s attempts to save the world’s coral reefs in Barbados. In pure Grand Tour style, they try to build a new reef using just car body shells as a foundation… and things don’t quite go according to plan. With a bit of inept crane driving, rubbish boat steering and an embarrassing incident with a local hotel, it makes for some great television.

Elsewhere in the episode, Jeremy gets to indulge his Alfa Romeo obsession, testing the new 500-horsepower Giulia Quadrifoglio. Hammond and May of course mock Clarkson’s obsession – with Hammond asking if he painted it “with a brush – or a bucket?”. In an attempt to persuade the others that the Romeo is better than the Porsche alternative that has been presented, Clarkson takes the others on a drive.
