Has anyone tried to find out the usable battery capacity of an Astra PHEV during normal driving? I owned a Vauxhall Ampera for almost 10 years, until it was written off in late 2022, and opted to replace it with an Astra PHEV. Both Ampera and Astra were specified with a usable battery range of 10.4 kWh, so I was hoping for similar performance, but I have been disappointed by the Astra. The Ampera showed total kWh used on the display, and when all of the battery was used the value displayed was usually 10.4 kWh (or very close to that). The Astra doesn't show a kWh value, but does give [B]miles [/B]and [B]miles/kWh[/B] values, so on long trips when all of the battery capacity has been used, I have been dividing the [B]miles [/B]by the [B]miles/kWh[/B] to get a [B]kWh [/B]value, and I have been surprised to find out that this typically gives me a figure of around 9 kWh, significantly less that the expected 10.4 kWh. For example ... 38 miles at 4.1 miles/kWh = 9.3 kWh 74 miles at 7.9 miles/kWh = 9.4 kWh I would very be interested to know if anyone else gets the same sort of numbers. If so, we've potentially been mis-sold a car that has 10% less usable range than advertised, or my Astra has a faulty battery that needs to be replaced. I have raised a Customer Support request with Vauxhall, and after over 2 months and numerous emails they have decided to close the case because they appear to be unable to explain why the usable battery capacity is lower than expected, so I thought I would share my experiences to see if others are seeing the same issue. Any feedback from other Astra PHEV owners would be very much appreciated.
