The 1933 Swedish Summer Grand Prix (Swedish: Sveriges sommar-Grand Prix för automobiler) was arranged by the Royal Automobile Club (KAK) and held at 6 August on a 29.7 km (18.5 mi) circuit at Norra Vram. The circuit was made up at regular countryside roads at a place very close to present day closed circuit Ring Knutstorp in Kågeröd. 12 laps were driven, making the distance 356.4 km (221.5 mi). The 10,000 krona prize to the winner was the largest offered yet for any race in Scandinavia. Astrid Lindgren was race secretary, and 160 policemen and 60 track marshals worked around the course.
