When Acura redesigned its popular MDX crossover for 2014, press materials specified 90.9 cubic feet of maximum cargo room, a significant increase over the prior MDX's 83.5 cubic feet. Still, something didn't quite add up. The new MDX was 2 inches longer from bumper to bumper, but height and width had decreased 1.5 and 1.3 inches, respectively. How had cargo room increased 8.9 percent?
Acura explained: Maximum cargo room was actually 68.4 cubic feet, not 90.9 cubic feet. It explained both numbers in the fine print on its consumer website as "based on [the] SAE J1100 cargo volume measurement standard plus floor space between first and second seats and front seats moved forward. This figure compares more accurately with most competitive measurements."
That should certainly clear things up for shoppers trying to find a car with enough room to get the kids to soccer practice or cross-country for a summer vacation.
