While I don't think it's TOO bad, I do believe that rear window adds significant wake area, somewhat comparable to that which is created at the rear of the car's deck lid.
I think "fixing" the flow there at the window area could lessen the rear drag by at least 30%. No expert, so input is necessary here. (Phil?!?) |
Yeah, I'd say definitely a rear spoiler.Ford has the roof falling off as it moves rearward and then I think we'd all agree that she separates at the backlight header,then may re-attach.Don't know.I do know that the angle between the rear edge of the trunklid and backlight is steeper than what Dr.Kamm would accept.He advocated no more than 10-degrees.You could probably cheat a little,say 12-13.
I'd do like CAR and DRIVER on the Pinto and Z-Car.Angle the spoiler up to the rear at 30-degrees and take it as high as you can live with.In a perfect world.the spoiler would reach up until it intersected the imaginary line of the Kamm or Jaray roofline which is what the template is all about.
Also,the straight-back foil,as on the Fusion is good,it just has to go way back before it intersects the 10-12 degree line.
Oh,by the way,999 was the number of Ford's first race winner.I think Barney Oldfield drove it to victory.That's why they used it on the Fusion.
