As computational fluid dynamics plays a crucial role in vehicle body design, the CFD committee, one of the technical committees comprising JSAE, embarked on a benchmark project in which a number of CFD codes would be tested on the same vehicle body. A wind tunnel test of the 1/5 scale model was conducted to provide reference data for the benchmark test. In this paper, details of the measurements are presented. On the body surface, smooth flow patterns were visualised by tufting. It was also found that total pressure loss in the wake of the model displayed a unique pattern similar to a mushroom cloud.
