The consensus seems to recommend that the test vehicle constitute no more than 5% of the test section cross-sectional area.Only a few tunnels qualify under this criteria.
Hucho does mention that the Pininfarina tunnel,while quite small in comparison,does produce numbers within the 2.5% standard deviation,which is right in there with the big league.
A2 may have some things figured out.Don't know.
