They're back! Because they think they can do better. Top Gear presenters Jeremy Clarkson and Richard Hammond feel their first Perfect Road Trip ended badly - and this time they're determined to get things right. So, they're off to Italy, travelling 500 miles from Venice to the isle of Capri via Bologna, Siena, Rome, Pompeii, Sorrento and Positano on the stunning Amalfi coast. Pulling out all the stops for perfection they pick the McLaren 650S and its fellow 200mph-clubber, the Lamborghini Huracan. Throw in the mind-boggling 900 horsepower hybrid McLaren P1 and you see they mean business.
