The section of the road between Budapest and Kecskemét was opened in 1934 as part of the Budapest-Belgrade international highway.

In the following decade, the arrow-straight section near Gyón was the venue for the prestigious international drag races of the era.

On the more than 5 km long straight, horizontal concrete section of the track, German racing driver Hans Stuck set a world record in 1934 with a speed of 321 km/h.

A reminder of the world speed record era is the restaurant between milestones 45 and 46, built in the 1930s to cater for guests arriving for races.

(According to other data, the Minister of Trade and Transport had already declared it a primary trunk road in 1934, numbering it 5.)
