Jethro Bovingdon tests a Porsche 911 GT3 RS 4.0 on the epic, desolate roads of the Scottish Highlands. On a rare sunny day, he's also joined by an iconic Carrera GT supercar to help him determine whether the 911 is the greatest Porsche of all time.

Jethro Bovingdon heads to the French Riviera to put a BMW M3 through its paces in the mountains above the Mediterranean. He's joined by rally legend Ari Vatanen, who attempt to convince him that the 30-year-old icon can still cut it in the Alps.

Jethro spends five days with the McLaren P1 crossing the Spanish Pyrenees. Starting on the edge of the Mediterranean in Barcelona, he heads up into the mountains that separate Spain from France, on en epic trip that ends a thousand miles away in Bilbao.
