The Super Truck Racing Assoc. of North America (STRANA) made its debut with 3 demonstration events for 2004. These 12,000 lb, 1,500 hp semi trucks can reach 60 mph in 3.5 seconds, and top out at over 100 mph in less than 6 seconds. Large trucks have been racing in Europe and Australia for years, so entering the US market was just a matter of time.
