Here’s your first look at the next episode of all-new Top Gear TV. And for Sunday’s show, we’ve brought out the big guns.

Yep, Chris Harris takes on Aston Martin’s astonishing 820bhp Vulcan; Gaydon’s £1.8m track-only hypercar. The venue? None other than the Abu Dhabi GP circuit. At night…

Elsewhere, Rory Reid takes on Tesla’s all-electric Model X SUV – complete with those crazy doors and supercar shove – in New York to see what’s what.

And for our main event, we’ve got another classic TG race: Chris Evans, Matt LeBlanc and Sabine Schmitz strap into second hand cars – including an old Jag and an Audi – in a race against Eddie Jordan on a train. The Orient Express, if you’re talking specifics.

The reason? To prove that travelling by road is better and more luxurious than taking the train.

We’ll also have celebrity guests in the shape of Bear Grylls and Professor Brian Cox, so click above for your big episode four preview.

Tune in Sunday, 8pm on BBC Two and BBC Two HD, and don’t forget to catch Rory and Chris on Extra Gear at 9pm on BBC Three and BBC iPlayer.
