Modifying Under-Car Airflow, Part 2

A seminal paper was recently written by Volvo’s Dr Simone Sebben (SAE paper 2004-01-1307). It covers the computer modelling of undercar airflow,

The car is unnamed but it is likely a soon-to-be-released Volvo, ie a current, aerodynamically designed car.

Chances are, it was the 2006 Volvo C30 and the later C30 / S40 / V50 DRIVe models - which are more FE variants based on the PSA 1.6 diesel version.

Designing the rather short C30 on the same platform as the S40/V50 was an aerodynamic challenge to give it a good Cd.

The C30 DRIVe has a partial bellypan - the only Volvo that I know to have one (not counting the cosmetic "offroad"-plates) - while wheelspoilers have shown up on DRIVe models (and scores of other cars).
