Not much has changed this year when it comes to the 2006 Acura MDX, aside from some slight interior modifications. This four door, seven passenger SUV features a 253 horsepower 3.5-liter V6 with a 5-speed automatic, ABS brakes and traction control as standard. The MDX is not designed for off-roading, with no low-range gearing available. In addition to solid safety features including airbags that protect all three rows of seating, the MDX features a nice range of standard equipment that includes auto climate control, front and rear air conditioning and a trip computer.
