The Grand Tour Madagascar episode will be in Amazon's hands in the next two weeks, Jeremy Clarkson has confirmed.

Speaking with the show's executive producer Andy Wilman on the DriveTribe YouTube channel, the pair concluded they'll have a final edit with Amazon in the next two weeks. And then it's up to Amazon to decide when to put it out.

"Amazon never tells us when they’re going to put it out until they’re sure because we have big gobs," said Wilman.

Clarkson continued: "So if you want to know when the next instalment is coming, ask Amazon, not us."

Why has The Grand Tour Season 4 taken so long to put together?

Wilman explained why the editing process is so complicated. "Most shows shoot a 10:1 ratio, which means they shoot 10 hours for every one hour that goes on TV. We shoot 1,000:1. Most of that is the three guys talking. The guys do have off buttons for microphones – Hammond gets confused and turns his microphone off when he's talking about the car, but when he's talking about Mindy [his wife] or horse b*ll*cks it's on."

Clarkson added: "That's twice as much as David Attenborough shoots waiting for polar bears to come out."

Wilman continues: "It then takes five weeks to get all the footage into the machine because it's 4K and all that stuff. That's before an editor can access it – then there's five weeks of him breaking it down, taking out the bits of James [May] having a fag. Then he has to match up all the cameras. Then there was Christmas. Then there's three months of shaping it – we set off without a script so there's a lot of back and forth."
