Sports Listings: This Weekend / Motor racing: Thunderdrome Challenge, Earls Court

Short-circuit racing's appeal is aided by the fact that spectators can watch every lap on the oval course and this weekend the Thunderdrome Challenge brings together a host of leading drivers in this stock car sport, including three world champions. It is the first time Britain has staged an indoor stock car event and Earls Court 2 in London will ensure comfortable spectating for the three shows over the weekend. Three classes will race. 1700cc modified saloons, known as national hot rods, will be complemented by the smaller 1600cc saloons or hot rods and superstox, which are single-seat, hand-built machines. With 16 cars in each race, jockeying for position, the racing will not be dull.
