Thanks for the welcome!

The aerodynamics of the Calibra are state-of-the-art even today, and it was a world record when introduced in 1989.

This car has Cd 0.26 and frontal area = 1.93 square meters. So its SCd (the real parameter) is 0.5018 in metric. An Audi A2, with 0.25 x 2.18, has worse aerodynamics at SCd = 0.545

.

For those interested in aerodynamics here goes a nice article on the subject, at the end they analyze the aero tricks used on the Calibra:
