It normally gets 58-60MPG in commute.

According to calculator above the load should have gone up by 25%, and if you consider torque to be constant RPM (load) had gone up by ~50%.
Hi cyclopathic,
What's the problem? If you take a load (power) increase of 25% and a speed increase of about 20% You get a work increase of 50% which should be the same as the rate of increase of fuel consumption, if the engine efficiency is unchanged.
