Comparing the H3 in size to the most popular mid-sized SUV the Ford Explorer (which I can't stand), it is actually 3" shorter!, only 1.5" taller, and only 2" wider than an Explorer:
Ford Explorer Exterior Dimensions
A. Wheelbase (in.) 113.7
B. Length (in.) 189.6
C. Height – empty (in.) 72.1
D. Width (in.) 72.1
E. Track width – front/rear (in.) 60.9/61.3
...That is MUCH smaller than I expected and pretty disappointing.
And btw, according to the Honda website, the accord sedan is 189.5" long making it nearly 3" longer than the H3.
