In the first ever episode of Petrolhead Planet, Jethro Bovingdon heads to the Scottish Highlands in what might be the ultimate Porsche, a 911 GT3 RS 4.0. This motorsport-inspired 911 doesn’t disappoint, but what about the epic, desolate roads of northern Scotland that make up the North Coast 500? On this trip Jethro encounters the best and worst of British weather, but on the day the sun shines he’s joined by the iconic Carrera GT supercar, to help him determine whether the 911 GT3 RS 4.0 is the greatest Porsche of all time.
