As the series literally got back on track with the last week's episode, the fourth and the upcoming episode is just around the corner.

The 30-second promo shows that the trio is back in Whitby this week. They will be seen driving some cars made of sustainable material before they take part in an environment-friendly motor event.

The promo teases James May's vehicle sinking into a lake as he admits, "May be leaking slightly," while Clarkson's car stirs a little controversy as his off-roader seems to be covered in animal skin and fur and different other body parts.

Meanwhile, an eight-foot-tall sculpture of Jeremy Clarkson's head has been spotted on the back of a lorry in Washington, DC.

The trailer also teases that the upcoming episode will draw a comparison test between the latest Porsche 911 GT3 RS and BMW M4 GTS.

The third episode of the Grand Tour garnered accolades last week amongst its fans worldwide while the trio were seen driving some spectacular cars such as Clarkson's (Brown) Aston Martin DB11, Hammond's Dodge Challenger SRT Hellcat and James May's Rolls Royce Dawn across Italy

Watch The Grand Tour episode 4 live on Amazon Prime Video every Friday.
