The Australian Automotive Research Centre (AARC) offers an extensive range of automotive engineering services to all vehicle and component manufacturers. AARC occupies a 1000 hectare site near Anglesea, 125km south-west of Melbourne and is the largest privately owned and independently operated automotive testing facility in Australia. Test facilities encompass virtually all driving conditions found in Australia, accommodating vehicles from passenger cars and four wheel drives to heavy trucks and mining equipment. There are many test roads and a variety of surfaces, including a 4.2km hot mixed surface road designed for testing component and vehicle durability. Other roads and sites include a series of gravel and dirt surfaces designed specifically to test road and in-cabin noise, suspension, braking and traction control systems, dust entry, cooling systems, chassis durability for trucks, and many other aspects of vehicle performance. There are also areas designed and approved for testing and development relating to Australian Design Rules (ADR).
