Toyota's next-generation Supra sports car has been subjected to testing in Australia to confirm its suspension tuning and dynamics are suitable for the local and world markets.

Chief engineer Tetsuya Tada and engineers from Japan have put a Supra prototype through its paces on Australian roads, supported by Toyota Australia's highly regarded vehicle engineering and development (VED) group.

The five-day evaluation and suitability test involved areas where Supra customers are likely to travel, including sweeping country roads, twisty mountain climbs and the Great Ocean Road - considered one of the world's great drives.

Mr Tada said he had been keen to use Australia's roads to confirm performance targets for Supra and ensure it would satisfy the dynamic preferences of local drivers.

"Working on aspects of handling and other details here in Australia allows us to make refinements that will result in a better car right up until production starts in the first part of next year."

Mr Tada said the local VED group, led by Paul Diamandis, was regarded among the best in the world for suspension tuning and dynamic evaluation.

He said Australia offered surfaces that replicated 80 per cent of the world's roads, including some of the toughest that would be experienced by customers anywhere.
