The hybrid fuel consumption may be obtained over an 11 km long distance. True. But this is done with a depleted battery. The plugin hybrid fuel consumption is derived from the hybrid fuel consumption as:ChrisMiller said:According to Wikipedia (so by no means infallible), the European fuel economy test is only 11 km long. The only reason I can see why the PHEV wouldn't give a 'zero' figure is that it includes a brief spell at 120 kph.anko said:The plug in hybrid fuel consumption is calculated over an imaginary trip of 75 km.
In general: ((0 * EV range) + (hybrid consumption * 25 km)) / (EV range + 25 km)
For the PHEV: ((0 * 52 km) + (5.8 l/100 km * 25 km)) / 72 km = 1.9 l / 100 km.
The 25 km is prescribed by the test and suggests how far you need to drive to the next charge station after depleting the battery.
So, roughly plug-in fuel consumption is one third of non-plug in consumption. But this applies to our PHEV. With a smaller battery, the factor would have been bigger. With a bigger battery the factor would have been even smaller.
