Although impossible to see the vehicle shape under the heavy camouflage, we can easily infer that the covering extending from the roof over the rear end is propped up like a tent hiding the true contours of a sloping coupe like roof line...
The X6 from Acura?
Spy snappers caught this Acura CUV prototype while testing in Germany at the Nürburgring circuit. With segment busting sporty crossover/SUVs like the X6 from BMW filling orders for 2008 despite difficult economic conditions on the global automobile markets, apparently more car makers are developing their version as well. And in this case it's Acura, the luxury brand from Honda.
Although impossible to see the vehicle shape under the heavy camouflage, we can easily see that the covering extending from the middle of the roof over the rear end is propped up like a tent hiding the true contours of a sloping coupe like roof line similar to the X6. Furthermore, looking through the tail light and license plate cutouts in the cover, you can see the angled position of the tail lamps and rear body sitting away from the cover while following a sloping trajectory up towards the roof. Also, in one of the attached photos the downward sloping roof line is seen in the top of the rear door window frame.
Seeing an Acura model, distinguished by its prominent front shield grille, being testing in Germany begs the question - could Honda bring Acura to Europe just as Nissan has done with its luxury brand Infinity this year?
Engines are unknown at this point, but the well known 3.7-liter V6 would be an obvious choice followed by a (long overdue and possibly too late) new V8 engine which Acura officials have confirmed will be introduced.
