Adrian's Tomcat 100"

Off Road Challenge Motors

Some of the most extreme and most capable off roaders are now used in Challenges such as the Scorpion Racing Challenge. They involve getting to nearly impossible locations to punch a card attached to the vehicle usually using one or more winches to aid traction up steep hills and inclines.

As second hand Landrover Defender 90s and 110s with coil springs the same as Range Rovers (replacing the Series Land Rovers with cart / leaf springs), become cheaper it is not more common to use a Defender 90 or 110 in stead of building a hybrid (eg. putting a Land Rover or Defender body onto a Range Rover chassis) or cutting up a Range Rover. A newer Landrover Defender 90 or 110 may (may!) have less rust than an old Range Rover. However Defenders do not come as standard with a 100" wheelbase or a fibre glass body on a full roll cage.

Defender 110

I could take a Landrover Defender 110, remove half the bodywork, then add a tray back and a 3.9L Rover V8 engine (from a previous vehicle), 2 winches and some other off road bits to produce a winch challenge vehicle. I could then enter events such as the Scorpion Racing Challenge as Cliff Garrod and Paul Church do in the yellow Defender 110 shown below.
