E Pace 300E query

[Redhorse003]

Only a general enquiry if anyone would know if the E Pace PHEV records separate figures for using the battery and mileage on petrol power.

Pretty certain the answer is no, only records either instant or average mpg.

This is a great topic as generally owners like to know how efficient their cars are, or are supposed to be. In addition of course this can be an early indicator that not everything is quite right with the vehicle.

With the conventional cars we all know that the MPG of MPL reading is the normal method of monitoring efficiency. With cars such as the I-Pace the convention is either Miles per kilowatt hour (m/kWh) which would be a similar relationship to the MPG reading. However some EV's, including Jaguars use the reciprical reading to m/kWh which is kWh used in 100 miles or kWh/100ml. Very confusing.

Then we come to the plug in hybrid cars such as the Jaguar E-Pace. I am not 100% familiar with the read out configuaration of the E-Pace but the difficulty with all Hybrids is 'how do you accommodate the two different systems'.

If the car is running in electric it will register mileage with no fuel used and therfore the MPG will rise. Therefore, for example you could complete 300 miles of short journey's on electric and record a very high MPG as no fuel has been used. The Hybrids that I am familiar with also provide a reading for the electric use in either m/kWh or kWh/100 miles. A good reading for the fully electric I-Pace is, 2.9 to 3.3 m/kWh but I have not found the Hybrid cars as good, therefore if you have access to the hybrid E-Pace it would be really interesting to hear about your experiences. Your should find something similar for the E-Pace PHEV - i.e readouts for both the MPG and the kWh/ml and these should be both instant and average for both readings.

I was also hoping to cover the hybrid Jaguars in the SUV section of the magazine so any thoughts for this would also be interesting.

Kind regards

Hi Paul - as you say, this is a complicated subject! To my mind, it’s not just how many miles you’re getting per kWh, but what that kWh cost you in the first place. My cheap overnight rate at home is 7.5p, whereas the public charger down the road would be 58p per kWh!

Also, back in September the range for a full charge was over 30 miles - now it’s colder it’s showing about 24, so miles out of a charge varies to quite a degree and is not a constant like a gallon of unleaded.

Incidentally, my P300e e pace is back with JLR as once the ICE has run it now refuses to go back to EV, unless you stop, turn off and back on again. This fault seems to be taking quite a while to be diagnosed.

Best regards, Simon.
