BIGGER THAN BIG! That's the only way to describe Summernats 4. More people, more cars, and more attractions meant more action. "Brute Horsepower" can show the feeling of being there in amongst the cars and the crowd. The Street Machine Summernats is designed around cars, fun and sun; so crank up your VCR, turn up the volume and relive 3 days of high horsepower madness in the Cruisin' Capital of the world, Canberra.
