They're calling the wheel fairings on the 2010 Brabus E V12 "Speed Spads." Don't laugh too hard, with 800 HP and 1047 Lb-Ft, it'll rub dirt in your face all the way to 230 MPH.
As you can tell from the trashy vanity plate, there's only going to be ten of this generation of the E V12 ever made. Despite the ugliness, we find that kind of sad, the world needs more 230 MPH four-doors.
DISCUSSION
My 1982 Olds had them. It didn't need them, but it had them. I didn't know that they helped the speed, but maybe I just wasn't trying hard enough.
