The teams adapt their vehicles to drive miles of forest track, rescue a (stuffed) cat from up a tree and chop down a Scots pine.

The teams visit the coast, where they must modify their motors to race across sand, recover a buried key and climb a Sahara-sized sand dune.

The teams must modify their rally racers to head across miles of moorland track, pick up a scrappy metal sheep and and launch it 15 metres through the air into a sheep pen.

The teams have just two stages left to determine who will win the rally. They must convert their racers to push a large metal boulder along a track to the top of a hill.

In the final stage, the teams must convert their vehicles to rescue a whisky barrel from a loch and carry it through a forest and over a steep bank before heading to the finish line.
