auto24ring (also known as Audru Ring, Pärnu Ring, Sauga Ring and EST-Ring) is a motor racing circuit in Papsaare, near Pärnu, Estonia. It is operated by A2 Racing MTÜ and is the only permanent road circuit in Estonia. The track has two configurations, the 1.5-kilometre (0.93 mi) Grand Prix circuit, and the 2.2-kilometer (1.4 mi) Long Circuit. The circuit hosts rounds of Baltic Touring Car Championship and other Estonian, Finnish, Baltic and North European Zone events.
The first competitions at the location of the circuit were held in 1930's. The original layout, called Sauga Kolmnurk (Sauga Triangle), was a 6.1 km long circuit utilising three public roads: Nurme tee, Sulu-Papsaare tee and Haapsalu maantee. Racing activities at the Kolmnurk ceased in late 1960s.
A new circuit, designed by Enn Teppand was built in 1989–90. This 3.668 km long layout included one of the corners of the original Kolmnurk as well as two, shortened, straights on Nurme tee and Haapsalu maantee. There was also a new section introduced consisting another public road and a short purpose build section.
In 2000, construction of the current circuit begun. The current circuit, opened in 2001, is designed to minimize the use of public roads. The 2.173 km long layout uses the sections added in 1990 plus a new straight and a chicane. A 350m long straight on Nurme tee is all that remains of the original 30's circuit.
