The MDX is bulked up compared to its predecessor, but it also enters a field that has improved considerably. It outpowers the Mercedes-Benz ML350 and Lexus RX 350, and neither of those has a third row of seats. The new BMW X5 3.0i offers a third row and very good handling, but its base price is almost the same as our loaded test car, and it doesn’t have the power of the MDX. The closest competitor is the Audi Q7 3.6, which is close in power, torque and price. Start adding options, however, and the MDX holds its edge in value. Other competitors include the Cadillac SRX, Volkswagen Touraeg, Infiniti FX35, and Lincoln MKX.
