That leaves us with so little to work with that we'll send the ball back to your side of the court with these suggestions:
The $43,185 MDX has been redesigned for 2014 and is quieter, more refined and more fuel-efficient (18/27 mpg city/highway with optional all-wheel drive) than the previous generation, which had more attitude and was more performance-oriented.
The $48,595 Q7 is more driver-oriented than most luxury SUVs, but the current model debuted for the 2007 model year — ancient history in the auto industry. A redesigned Q7 is expected in the U.S. in 2015, and it should be considerably lighter than the current model's 5,567 pounds (versus 4,255 pounds for an all-wheel-drive 2014 MDX). The all-wheel-drive MDX's mileage is almost as good as the Q7 TDI diesel with standard all-wheel drive, which is the more efficient option of the available engines at 19/28 mpg. Compare other MDX and Q7 specifications here.
If you're concerned about reliability, Acura has finished above the industry average in the last three J.D. Power and Associates Vehicle Dependability Studies, which measure problems in the third year of ownership. Audi has been below the industry average in those three years. Acura was eighth among 32 brands in the most recent study, and Audi was 23rd.Related
