The accompanying chart indicates the coefficient of drag for 2012 Subaru models.



Cd measures aerodynamic efficeiency – the lower the number, the better

2012 Subaru Models

WRX/WRX STI 0.34-0.35
Outback 0.37
Forester 0.375-0.382
Tribeca 0.38

Perhaps you’ve never considered the aerodynamic design of a Subaru. Aerodynamics are part of every model, and the emphasis that Subaru puts into the aerodynamics of its products has been reflecting its engineering prowess for years. As an example, in the mid-1980s, Subaru introduced its XT Coupe, which had the lowest Cd of any mass-produced car at that time – 0.29. (See article on the 1986 XT Coupe in Summer 2011 Drive.)

The Cd measurements of 2012 Subaru models are not much more than the XT Coupe’s 0.29. All are within 0.10 Cd of it.
