>runs at about 31mpg, which is 13.2 km/l or 15.3 km/kg The measurements outside North America are reciprocal, e.g. 7.7L/100km (which is awfully inefficient for a diesel, normally it should be around 5L) So converting gallon to liter, and mile to kilometer is the wrong way to present it. As for the efficiency in general - of course electric engines have a very high efficiency (in the 90s), unlikely diesel which can barely hit 35%.
