The all-new ZDX is Acura's answer to the BMW X6. About the same size as the MDX, the ZDX features a swoopy coupe-like roofline rear door handles concealed in the window pillar, similar to the European-market Honda Civic (Acura is a division of Honda). Acura hasn't announced engine specs, but it will most likely be Acura's 3.7 liter V6. We do know the engine will drive all four wheels via a Acura's first six-speed automatic transmission.
