Fuel Efficiency Numbers Overstate MPG More For Cars With Small Engines

whoever57 writes: All official numbers for fuel economy in the EU typically overstate the miles-per-gallon figure that drivers can expect to achieve in typical driving. A recent study confirmed this once again. However, what the study also found was that MPG figures are more unrealistic for cars with smaller engines than for cars with larger engines. Actual MPG figures achieved based on typical drives for cars with small engines could be as much as 36% under the official number, while those cars with 3-liter engines would typically achieve 15% less than the official figure. These discrepancies need to be accounted for if we're going to be serious about regulating fuel efficiency. But then, we should be using gallons-per-mile instead of miles-per-gallon, too.

Your car can't even make it between gas stations, sadly.

40 rods = 0.125 miles
1 hogshead = 63 (US) gallons

0.125 miles / 64 gallons

0.001953125 / gallon

10.3125 feet/gallon
