Top Gear - Season 22

In this first episode of the series, Jeremy Clarkson, Richard Hammond and James May are in Russia for an incredible race across the vast and very beautiful urban landscape of St Petersburg. May defends the honour of the car in a very small Renault, Hammond tries to prove that pedaling is faster by saddling up a bicycle, whilst Clarkson attempts to demonstrate that water is the quickest way across town, especially if you're in a hovercraft. To make matters more complicated, all three presenters are racing not only each other but also The Stig, who is silently making his way towards the finish line on public transport. Also in this episode, Richard Hammond is at the test track to find out if the dramatic new Lamborghini Huracan is as flamboyant and fun as an Italian supercar should be. Plus, celebrity guest Ed Sheeran tests his steely eyed driving skills as the star in the Reasonably Priced Car.

Jeremy Clarkson, Richard Hammond and James May embark on a grand road trip across Australia's Northern Territory.

Tasked with picking a fast, luxurious GT for the trip, Clarkson chooses a BMW M6 Gran Coupe, Hammond a Bentley Continental GT V8 and May a Nissan GT-R, as the trio set out on an adventure that takes in crocodile-infested rivers, a race around a vast open-cast mine, an encounter with the world's longest lorries and the majestic scenery of one of the world's least-inhabited landscapes. Their dusty endeavour concludes with an unusual challenge involving a farm, their cars and 4,000 cows.

Also in this episode, Hollywood legend Kiefer Sutherland is the star in the Reasonably Priced Car.

Jeremy Clarkson, Richard Hammond and James May conduct a valuable piece of consumer research with their attempts to improve and enhance the ambulance.

Starting with a belief that current ambulances, which are usually very big and based on a diesel van, are in need of a rethink, the presenters go their separate ways to focus on the one area they think could be improved. May focuses on passenger comfort, Hammond tries to improve response times by getting other drivers out of the way more effectively, while Clarkson confronts the same issue with the invention of what he calls 'the sports ambulance'.

Their three very different creations are then put to the test with a series of severe and often messy challenges, culminating in a fast reaction to a spectacular emergency.

Also in this episode, F1 driver Daniel Ricciardo is the star in the Reasonably Priced Car.

Jeremy Clarkson tests the new BMW M3 at the track before switching to another BMW, the space-age, hybrid-powered i8, for a revealing trip up the A1 to Whitby. When he gets there and is fuelled by a portion offish and chips, Clarkson must decide which of the two cars he would rather take for the drive home.

Also in this programme, Richard Hammond marks the imminent demise of the legendary Land Rover Defender with a heart-stopping attempt to drive one straight up the side of a dam.

Meanwhile, James May makes a rare trip to the Top Gear track to test the brand new 500-horsepower Mercedes-AMG GT.

The stars in the Reasonably Priced Car are actress Margot Robbie and Hollywood superstar Will Smith.

Jeremy Clarkson and James May encounter artillery shells, corsets and classic hot hatchbacks as they take a nostalgic look at French company Peugeot, while Richard Hammond is at the test track to compare the Porsche Cayman GTS with the latest Chevrolet Corvette. James also takes the 950bhp LaFerrari hybrid hypercar out for a spin in Italy, and singer Olly Murs is the Star in the Reasonably Priced Car.

In this week's programme, Richard Hammond is dropped into the remote, frozen wastes of Canada to test a watch with a built-in emergency beacon. The distress signal is sent directly to Jeremy Clarkson and James May, who get their hands on two machines and set off on an epic adventure to find their colleague. Plus, Jeremy puts the new 471bhp Lexus RC F coupe thought its paces, while The Fall and The X-Files star Gillian Anderson takes to the track in the Reasonably Priced Car.

James May straps into a highly tuned hatchback as he competes in a world rallycross race, with Top Gear USA host and professional driver Tanner Foust teaming up with him. Jeremy Clarkson puts the latest Jaguar F-type R and Eagle's modernised E-type the Low Drag GT though their paces, while Richard Hammond is in Spain to test the new version of the Mazda MX-5. Plus, X-Men: First Class star Nicholas Hoult takes to the track in the Reasonably Priced Car.
