The Grand Tour: Season 1, Episode 4

1 - 4: Enviro-mental

The Grand Tour studio tent is back in Whitby, England for various complicated reasons, some of which are James's fault. In this show, Jeremy Clarkson tests the Porsche 911 GT3 RS, desperately trying to remain impartial despite knowing that Richard Hammond owns one, and then compares it to the track-focused BMW M4 GTS. Also in this episode, the hosts become unusually ecological as they attempt to create cars made of truly sustainable materials before taking part in what's billed as a green motorsport event.
