Hatchback or sedan for the Accent?
Also, which engine in the Mirage -- apparently came with a 1.5 or 1.8 in 2000.
The Mitsu seems rated better all around than the Accent.

Also, note that it's not unusual for manual cars to beat the (modern) EPA ratings by a fairly wide margin, when driven conservatively (simply by always upshifting as early as practical).

It'd be pretty safe to expect the Mirage to beat its rating as well.
