In theory I agree with you but A dynamometer would measure the energy delivered at the wheels which does not directly relate to battery capacity as some of it is used other than by the driving motor It is quite valid to use the car instrumentation although it does leave it open for MG to say...

Thanks for your input Another issue is that the % charge left indicators is very non linear. It’s skewed to make the mileage look good when the car is more than 50% full I’ve checked this. The only non driving significant use of power is the ptc heater and to some extent the aircon. Both do...

I think it is likely that all MG4 - 77s have smaller usable capacity than claimed but I only have to prove mine to win a case in the small disputes tribunal Mine is 15% less than the model name suggests and 10% less than the small print claim It really doesn't matter whether that's one year's...

The calculation is high school physics! The measurements are from the vehicle's own instrumentation. If MG want to claim that's no good, then.... I like your analogy ! I guess that if, after eating a meal, I read the menu more carefully and found that it should have had say three meatballs, but...

Of course, the distance the car will travel will vary according to driving and weather, you can tell that easily, mine can vary from about 7km per kWh on a good day, to under 5 when it's cold and raining hard. However the capacity in kWh is absolute, and I have measured it as 15% below the...

There’s a lot of talk about poor range on MG4. Very hard to quantify as driving and weather have huge influence. However kWh capacity is numerical and can be measured easily. Mine is a 77kWh model and in reality is only 67, so I’m commencing legal action. [ Moderator: Deleted redundant text...

Measu Very simple. Fully charge Zero the accumulated journey recorder Drive till battery % is zero Then you have used all the useable capacity as the car is no longer safely drivesble The car displays distance covered and kWh per 100km (or maybe per 100 miles in some areas). Multiply the two...

I’m disappointed with the range of my MG4 77kWh and as an electrical engineer I’ve looked into the battery capacity, which is easily measurable. My initial findings are that it is far short of the claim, less than 70kWh. The MG agent has no credible explanation for this, and I’m commencing legal...

I have done an exhaustive test on my MG 4 77 and find the usable battery capacity between a fully balanced full charge and an indication of 0% is consistently about 68 kWh which goes someway to explain the disappointing range compared with the claim figure. I have tried to claim under warranty...
