Top Gear : Season 23

This week, Matt, Chris and Eddie Jordan take music stars Sharleen Spiteri, Seasick Steve and Tinie Tempah on the ultimate SUV test in wildest South Africa. Back at the track, F1 superstar Jenson Button gives Chris a ride in the McLaren 675LT, while actor Damian Lewis is this week's Star in a Rallycross Car.

Boxer Anthony Joshua and comedian Kevin Hart are this week's Stars in a Rally Cross Car.

Matt LeBlanc gets his hands on the new Porsche 911 R whilst Chris Harris puts Honda's reimagined NSX through its paces.
