The Mitsubishi Outlander PHEV is based on the older 2.0 engine and 10kWh battery rather than the later 2.4 engine with variable valve timing and a larger 13.2kWH battery.
The VW Passat PHEV again is based on the older 2015 model with the smaller battery, what is the point of performing a NEW independent test, when some of the data being used is OLD ?
Having said al that the new Volvo XC40 PHEV is near the bottom at 49.6mpg
And to be honest does anyone really fall for these inflated manufactures fuel consumption claims.
Unfortunately I have suffered a brain injury and occasionally I get confused and often say the wrong thing.
