OK, so the day finally came when I filled Eva up with petrol. I built up a spreadsheet (as you do) to highlight the MPG and the effect of using electricity. I won't share costs because my electricity tariff is not the cheapest, I still fill with V Power and the vast majority of charging is free. But the MPG looks like this:
Headline: 39.27mpg
Petrol Only miles: 19.92mpg
Total kWh: 95
Miles/kWh: 1.702
Virtual: 33.74mpg
That final figure is taking the total of my kWh and using my home charge rate (I only charge in 2 places currently - home and Country Club) ignoring the free electricity (which is running at about 2/3
) and then converting it to petrol using the price per litre and assessing it as if it were petrol. It made sense to me, but there's probably some flaw somewhere.
Looking at it from my driving habits, I generally do mostly 3-5 mile round trips: massively inefficient and the reason for the more than 50% electric running. The 19.92mpg should be tempered by the fact that my 95kWh is not responsible for all the electric miles due to re-gen and engine charging, so the engine does more work than just pushing the car along.
Then we can consider the performance in light of the Gorilla: the 19.92mpg on petrol running of Eva is higher than Gorilla's overall mpg over 5+ years and the 39.27 is double. This particular tank has done a bit of everything, from motorway journey with no traffic on collection all the way to electric only running to Sainsbury's which got me thinking: should I do one tank on "sport" only? - ie no electric running aside from overboost. I assume that will happen on a long road trip so I'll be proposing a repeat of this year's cross Europe journey so I can try that out.
No report yet: still smitten with it to be objective.
