The second generation of Acura's Canadian-built SUV goes after the likes of the BMW X5 and Porsche Cayenne, sporting a new emphasis on performance and athletic handling.
For the straight-line stuff, the engine has been enlarged to 3.7 litres and produces an emphatic 300 hp, though mechanical smoothness has been compromised in the process. The 5-speed automatic has an F1-style sequential paddle-shifting mode.
In addition to available Active Damper suspension, MDX also adapts the ingenious SH-AWD system first seen on the RL sedan. This street-oriented system (no transfer case, no diff locks) not only can vary front/rear torque distribution from 90/10 percent to 30/70 percent, it can also speed up the outside rear wheel during cornering. The result is neutral handling like that of a rear-drive sport sedan.
Longer and wider but lower than its predecessor, the MDX is still nominally a seven-seater, though it's really comfortable only for four; the second-row middle seat and the two rear ones are for occasional or small-person use (Acura calls it "4+3 seating"). Alternatively, six different permutations of cargo space and/or rear seating can be achieved. A new Trailer Assist System complements the 5,000-lb. tow rating.
New amenities include Tri-Zone automatic climate control and a new 253-watt, 8-speaker audio system.
