The Volt's calculation of MPGe or Le/100km, which should be based on a fairly standard calculation, comes up with a value that does not make sense to me. For instance, it routinely gives me around 100MPGe (2.3Le/100km) for my daily commute, which is about 87km (54 miles) on a full charge (14.6kWh). By most calculations, this should land closer to 1.9Le/100km or 125MPGe.
I'm wondering why there seems to be such a discrepancy. The industry accepted conversion is around 1-gallon to 33.70 kWh, so for my commute, 14.6kWh=0.43gal, 54 miles/0.43gal = 125MPGe.
