It is described as the most extreme contest on the planet, where 30 weaponised vehicles clash in a desert arena.
But according to Norfolk friends Jake Isbell and Chris Beatty, Sky One's soon-to-be aired Carnage competition was just 'proper good fun'.
The duo from North Walsham were chosen to enter the show after designing their own Mad-Max-style vehicle.
Their creation was built around a 2.8l Audi A4, purchased off Ebay for just £500.
But after weeks of work, it ended up having more in common with a mine clearing tank than a family car.
Mr Isbell, 24, said Sky transported the car from a garage in North Walsham to South Africa in February this year for the contest.
It was then up to Mr Beatty, 25, to drive - and attempt to destroy - the other team's vehicles.
'The car worked as intended,' said Mr Isbell.
'A lot of the other teams went for heavy vehicles, but ours was quite nimble as it was a four-wheel drive.'
In order to destroy the other cars, their Audi was fitted with a motor-driven flail, inspired by a Second World War minesweeping tank.
Several gas bottles, covered in nails, were also hooked up to the back of the car, which could then be dropped in front of other vehicles.
For protection, the pair installed an internal and external roll cage.
Mr Isbell said the vehicle, nicknamed 'Jeff', was built over six weeks from a garage on Burton Avenue in North Walsham.
He added that Sky gave them £7,000 to purchase and upgrade the car.
'It was nice to build something with someone else's money,' Mr Isbell,w ho works as an engine tester at Lotus, said.
'But we were both working full-time and so we would have to go to the garage after work, sometimes carrying on until 4 to 5am.'
While Mr Beatty, who works as a building draftsman, drove the vehicle, Mr Isbell said he was the engineer and mechanic.
Their team name in the show is 'Norfolk and Good'.
'It was proper good fun,' Mr Isbell said.
Sky One describes Carnage, which airs on May 6, as 'the most extreme contest on the planet'.
It is hosted by Freddie Flintoff, Lethal Bizzle and Vick Hope.
