aerodynamic chart
can someone post up the chart with the drag coefficient for the xB and the other vehicles it beats. the Diablo and such. i searched but couldn’t find what i was looking for
and the tc has a lower drag co-effcicient than the xb, and the xa has the best one of all scions.
besides, don't the intentionally have drag to keep the car more stable at the triple digit speeds they are made to experience on a reguler basis?

So i have some info on the Cd (Coefficient of Drag) for other aerodynamically challanged cars here: Volvo 245(station wagon) is 0.39, 850 wagon is 0.32. V70 wagon is 0.31. So if xB is indeed 0.35, then it is impressive since it is very close to "sporty" 850. Lowering the car will further decrease drag, as will installing smaller side mirrors (stock are huge!). Making rear rims/tires flush with the fender will probably help too. Nothing beats chopping the top though
Here's an exceptionally long post... this list was pulled from the Wiki for Cd. I've added the xB in there, as it was not included in this list.

Every time you turn around it's another damn Rumpler. Must be 10 on my street alone.
Rumpler, Rumpler, Rumpler. They're like roaches.
vertical height is only one part of coef of drag . the smothed edges from the front aka front plane to the sides as well as undercarriage , roof profile , trim pieces , door handles , spoilers or not , EVERY piece of EVERY vehicle changes coef of drag for both the good and them bad
