Ring Knutstorp is one of Sweden's most successful tracks, with a history stretching back more than 50 years. Undulating and relatively quick, the circuit is popular with spectators, thanks to the good views afforded by the banks overlooking the course.

The circuit was built by the Hyllinge motorsport club, which had been formed in 1948 by a group of enthusiasts, who began organising motocross events a few years later. In 1951, they had created their first course at Kågeröd, on the site of the present-day circuit. The club grew in stature and by 1958 organised its first World Cup event. In 1962 a new 0.684 miles road course was laid out, though it was not until the following year that it was asphalted. Short and twisty, it boasted the banked 'Liton' corner overlooked by packed spectator banks.

By 1970, the course was extended to just over 2km, with the pits and start and finish moved to the new extension. From the start, the new course headed to a double-apex first corner, then switching back through a series of challenging esses to rejoin the original course at a sharp uphill left-hander.

The circuit configuration has remained unchanged since 1980 but the track remains among the busiest in Sweden, with activity on most days through the summer, including manufacturer and club days, general testing and driver education events.
