Driving on all the roads off the world!
Our proving grounds in Korea include those at Namyang R&D Centre, Ulsan plant. The world-class California proving ground in the US covers an area six times the size of Yeouido in Seoul. With a combined area of 20 million m2, our proving grounds in Korea and the US enable driving tests that reflect all the speeds and road conditions that can be experienced by drivers.
Namyang R&D Center, Ulsan proving grounds
The proving ground at Namyang R&D Centre was completed in 1993 and is recognised around the world for its excellence. The 1.65 million m2 grounds feature 34 roads including a Belgian road and a 4.5 km high speed track to total 70 km of total testing roads. The Ulsan proving ground was the first of its kind in Korea when it opened in 1984. Covering an area of 660,000 m2, it features 19 road types including a high speed rack.

The California proving ground in the Mohave Desert boasts an impressive total test road length of 61 km, top speed of 250 km/hr and total area of 17.4 million m2. Constructed with a total investment of USD 60 million, the test site is approximately 10 times the size of the Namyang R&D Centre proving ground and is the third largest in the US operated by a foreign carmaker. The longest track is the 10.3 km oval, three-lane high speed track which allows for various high speed driving and endurance tests.
Main test road
- High speed road
- Under the Board of Directors, there are the Audit Committee and External Director Candidates Recommendation Committee. We further established the Ethics Committee in 2007
- Multi-purpose road
- Measuring 1.2 km long and 70 m in width, the road is capable of landing light airplanes. True to its name, it is used to conduct a diverse range of automotive performance tests and comparative trial runs with rival cars.

Low friction road (ABS test)
- Belgian road
- Many European countries like Belgium have very old roads. Due to their uneven, cobble-stoned surfaces, the roads deliver shock levels to cars that are approximately 100 times greater than regular roads. Accordingly, the Belgian road offers a chance to test the strength and durability of new cars and its parts within a short period of time.
- Low friction road
- When sprinklers shower water on road surfaces made of materials like epoxy, the friction coefficient of the road becomes equivalent to that of roads covered by rain, snow or ice. This enables tests for driving and braking performance on icy roads regardless of actual weather conditions.
- Dust tunnel
- Man-made dust is used to recreate road conditions which generate large amounts of dust. It tests the driver’s visibility and seal quality of the car body and parts.
- Various condition roads
- Diverse road conditions that can be found all over the world are recreated to ensure the same levels of ride comfort and noise levels regardless of the location. Recreated roads include pebbly roads, cracked surface roads, Seongbuk-dong road (Seoul), wavy roads, European asphalt road, long wave pitch road and the West Coast Highway.
