Inside the delta they come across a swamp they must cross. There they will encounter many deadly animals and so must reinforce their cars with added protection after they stripped them down for the Makgadikgadi. The next day the group discover they must drive through the Okavango Delta, the world's largest inland delta. They're forced to drive as the crow flies to the nearest gas station to fill up. After fixing the Lancia, the group realize they are almost out of fuel and their film crew are all running diesel engines. Clarkson's Lancia Beta Coupe, however, fails to start and African Stig decides to walk off into the wilderness. African Stig takes Hammond's Opel Kadet around in 1.12.0 and May's Mercedes 230E in 1.06.0. The group's cars are tested on a rally special stage with The Stig's African cousin behind the wheel.

Making it through that, they arrive at a village for their next challenge. They eventually make it out, but encounter the Kalahari Desert and its choking dust. Due to there only being a thin layer of crust on the flat, the group have to shed as much weight from their cars in order to not get stuck in the muck and die. It is almost completely lifeless and about the size of Portugal.

On their way across Botswana the boys encounter the Makgadikgadi Pan, the largest salt flat complex in the world. But should their car break down beyond repair, they will be forced to continue the journey in an old, white Volkswagen Beetle. The trio then discover their challenge: drive their cars on a 1,000-mile safari across the spine of Africa, from the Zimbabwe-Botswana border to the Namibia-Botswana border. Hammond decides to name his car "Oliver". May chooses a 1985 Mercedes 230E, Clarkson a 1981 Lancia Beta Coupe and Hammond goes with a 1963 Opel Kadet. They're given just £1,500 (about $3,100) to buy a normal two-wheel drive car. Jeremy Clarkson, Richard Hammond and James May leave the Top Gear studio and head to Botswana.
