Yağız Avcı and Dmitry Sotnikov are used to racing hard across the world's most inhospitable terrain as rally stars, however nothing could quite prepare them for a duel on one of earth's most dangerous roads - the D915 in Turkey.

Here is all you need to know:

- Five-time Turkish Rally Championship winner Avcı has stepped out of the shadow of his legendary father Nejat to become a star after completing his first race in 2002.

- Russian truck driver Sotnikov is a two-time Silk Way Rally champion, who has also placed second at the 2017 and 2019 Dakar Rally, so he knows how to master natural and man-made obstacles.

- The D915 from Trabzon to Bayburt is regularly named as one of the world's most dangerous roads thanks to its spine-chilling 13 hairpin bends over 13 gruelling kilometres at an altitude of 2330 metres.

- Built by Turks and Russians together in 1915, the terrifying hairpin bends on the foot of Soganli Mountain are seen as one of the toughest road challenges.

- Nevertheless Avcı and Sotnikov rose to the occasion with a thrilling duel on the narrow cliff road that takes no prisoners.

- Avcı, 35, revealed: "It was quite a risky track that did justice to its notoriety. The track was quite dangerous, but also very exciting and competitive. It was a high-adrenaline challenge with plenty of tight and hairpin bends, pushing the limits of the car and tyres. Stones and rocks created fewer problems for it (Sotnikov's Kamaz - Master truck) than for me. Our exhilarating race was a nice contribution to the story of the road."

- Sotnikov, 34, added: "I raced in the most dangerous rallies of the world, but I had never competed on such a narrow road with so many bends. It's a road with a marvellous view, but, naturally, the cliffs are scary. It also imposes a great psychological burden on the driver. You have to focus very well. When I found out that this road was built by Turks and Russians, I was fascinated by this great history. I felt special, just like this road."
