the devise (and the car) pictured above looks more subtle and stylish than what i'll show below
my kadett (also note the massive pop up whale tail spoiler )
here's another example on a citroen AX
both cars have a very prominent "lip" on the rear bumper... i suppose this is somewhat similar to the lip spoilers found on the rooflines of hatchbacks and sometimes trunklids on sedans... just something to get the air off in the right direction like Snax pointed out... note that the AX has a spoiler like portrusion at the base of the windshield... this was part of the trunklid and all models had this... i believe the cd of the car was around 0.32 wich is pretty good for something build in the 80's... it's interesing as the angle of the windhield would not allow the air to stay attached , but maybe the bump breaks some turbulence going on there. anyway, i just mention it as these are two cars that had a lot of aerodynamic features for the time, so i'm sure these bumps and lips are there for a reason other than looks...
the audi looks great, and is probably much more aerodynamic too, but on todays smooth styled cars it's sometimes hard to tell what's for looks and what's effective
Yes - I've seen similar on most Lexuses (Lexi??), though in painted plastic.
I think it must be to encourage clean separation.
Or you could call it a mini-mini Kamm back. Same idea either way, I'd think.
Currently getting +/- 50 mpg in fall weather. EPA is 31/39 so not too shabby. WAI, fuel cutoff switch, full belly pan, smooth wheel covers.
Seems like an easy addition to almost any vehicle!
