    Average full-size passenger cars have a drag area of roughly 8 sq ft (0.74 m 2). Reported drag areas range from the 1999 Honda Insight at 5.1 sq ft (0.47 m 2) to the 2003 Hummer H2 at 26.5 sq ft (2.46 m 2). The drag area of a bicycle (and rider) is also in the range of 6.5–7.5 sq ft (0.60–0.70 m 2). [5]
