Hi Chris, I did this on my converted petrol van - both before and after conversion. It was quite small - what is referred to as a 'micro-van' here in Europe. Before conversion it did around 36mpg on average for my daily commute - around 20 miles each way, 5 of country lanes at 30-45mph, 9 of highway at 55-60mph, 3.5 of suburban highway at 40mph and 2 miles in town at 20-30 mph - all assuming no heavy traffic which was the norm as I worked early, late and night shifts then and mostly drove out of the rush hours.
I logged my power consumption at evalbum.com/2092. Conversion saved me around £800 per year. Obviously, the longer the commute, the more you save. My 'car' commute is probably fairly average for this part of the world (commuter belt north of London) but there are a lot more people who drive all the way into central London every day rather than just to the outer parts of it as I do - so more like 30-40 miles and then there is the £8/day central London Congestion Charge to contend with - free in an EV! That on its own would go a long way to cover the cost of an EV lease/hire purchase payment. Regards, Martin.
