Our cars, occupying an average space of one cubic meter, are only born after withstanding winds of up to 124 miles/hour (200 km/hour) at the world-class US$45 million wind tunnel. They are subjected to testing on 71 different road surfaces including general test road, Belgian road, low-friction road, dust tunnel, various condition road, hill road and high-speed track at our proving grounds (Namyang R&D Center, Hwaseong, Ulsan and California in US) that total 5,105 acres (20 million square meters), not to mention hundreds of other tests including a road simulator, electromagnetic wave test, heavy rain/snow tests, and high/low temperature tests that evaluate heating, ventilation and air-conditioning (HVAC) systems.

Our proving grounds cover a total area of 5105 acres
(20 million square meters) and are located in Namyang R&D Center, Hwasung and Ulsan in Korea, in addition to the 4329 acres (17.52 million square meters) proving ground in California’s Mohave Desert. Vehicles are put through an exhausting array of tests at various speeds and under diverse road conditions.

Proving Ground

The Hwasung proving ground was completed in 1993 with a high-speed track and 16 tracks. The proving ground at Namyang R&D Center is of international standards. Opened in 1995, the site features no less than 34 roads including a Belgian road, and a high-speed track that is 2.8 miles (4.5 km) long. In all, the site features a total road length of 43.5 miles (70 km).

California Proving Ground

The California proving ground in the Mohave Desert boasts an impressive total road length of 72 miles (116 km), top speed of 155 miles/hour (250 km/h). Constructed with a total investment of US$60 million, the test site is approximately 10 times the size of the proving ground at Namyang R&D Center and is the third largest in the US operated by a foreign automaker. Eight test roads combine to form a total length of 72 miles (116 km). The longest track is the 6.5 miles (10.4 km) oval, three-lane highspeed track which allows a top speed of up to 155 miles/hour (250 km/h). The facility enables high-speed and endurance tests.
