This is the last in the present series of Banger Boys and a dramatic climax to the season, as Steve attempts to win the World Banger Racing Championships.
Flip and Steve need to win their qualifying races before they can get through to the spectacular final at the same event. But the boys are really struggling to crank their cars up to world final standard.
Steve is pinning his hopes on a Lexus, but all isn't going to plan with time running out. Flip is relying on a Nissan to bring him through this huge challenge. But it's a car he has never seen raced as a banger before so he has no idea how it will rate up against some of the UK's best banger racers.
Big Hoss is keeping well clear of all this strain, stress and adrenalin in the most unusual way. He's decided to join the all action girl's bowling team for a one off starring appearance.
