I did a bit of searching on this, and the short answer is: when the EPA lab tests a manual transmission, the test driver has to follow prescribed shift points, and they're not optimized for best fuel econony.

So in the real world, it's relatively easy for a manual transmission ecodriver / hypermiler to beat the city/combined EPA rating, sometimes by significant amounts. (Like 41% over, in the case of the 5-speed Mirage!)
