The future 2014 Acura MDX was recently spied on the Nurburgring during some test runs. Wearing less camouflage than when we last saw it, this 2014 Acura MDX prototype gives away a few of its design secrets. Acura is expected to equip the 2014 MDX with a 3.5-liter V6 engine with an output of around 300 hp. An all-wheel-drive version of the new MDX (2014) is also expected. The 2014 MDX AWD will probably have more than 300 hp from the same V6 engine.
