Metrobus Fuel Efficiency on the Rise

September 27th, 2012 8 comments

In recent years, the fuel efficiency of the Metrobus fleet has significantly improved, reducing Metro’s fuel expenses, and improving Metro’s environmental sustainability.

Metro’s bus fuel efficiency has increased by 27% over the past eight years, reducing fuel costs and improving environmental sustainability.

Over the past 8 years, the average fuel economy of Metro’s bus fleet has increased by 27%, from 2.96 miles per gallon (MPG) to 3.76 MPG today. The chart at right illustrates this trend, using actual odometer and fuel readings which are gathered and stored by our bus technology group.(Note that these figures include the consumption of compressed natural gas [CNG], expressed as gallon-equivalents. The slight dip in FY2011 is the result of some data loss during a transition to an electronic mileage tracking system.)

What is Causing this Trend? This steady increase in fuel economy is generally the result of technological improvements in the fleet.  Metro has been replacing older standard diesel buses with newer diesel-electric hybrid, CNG, and clean diesel models.  In particular, introducing diesel-electric hybrid buses to the fleet has helped push up the average: on the streets today, our diesel-electric hybrid fleets are achieving average mileage of 4.49 MPG.  Metro purchased its first hybrid bus fleet in 2006, and today these buses provide 41% of Metro’s bus vehicle-miles.commercial jumping castle for sale
