Defending New Zealand 4X4 champion Dan Cowper has designed a horror course for invited drivers competing in his second privately-organised Suzuki 4X4 Extreme Challenge in Turakina on Sunday.
The V8 truck builder will host the event on his 36ha farm on SH3 south of Whanganui, the home of his day job, Cowper Trucks.
Unlike courses on the national championship circuit that use natural obstacles, Cowper's series of hazards are man-made and this year they are a fearful set of hurdles for even the most daring teams.
Cowper won his fifth national title last year after then defending champion and fellow Whanganui driver Hamish Auret and his navigator Paul Barnes were forced to pull the pin with a round to go after blowing their 7L Chev motor.
Last year Cowper hosted his own gruelling event with six courses, each featuring hazards of differing degrees of difficulty. This year Cowper has doubled the trouble and has designed a 12-course track with several horrendously devilish hazards.
