Right guys, listen to me as I been using a Nissan leaf for nearly a year now.
Charging, from empty to full on home charger takes five hours and costs about ninety pence on economy seven. You will quite safely get sixty miles. If you rapid charge at ecotricity chargers it's free and takes thirty mins to eighty percent. As to the torque you have 260 lb/ft from zero to 100mph.
It is the smoothest and quietest vehicle you will ever drive. I'm getting the env200 in April which is better than the leaf and has a payload of 700kg.
The disadvantages are, in winter the range is affected by the cold and the need to run heater. You should still get forty miles safely.
If you need to charge during the day, although free and only taking thirty mins on rapid you are losing your hourly rate during that down time.
I love them mostly because the leaf and env will leave most cars standing from the lights. Test drive one. I'd recommend the env, Peugeot partner and any plugin hybrid.
Also because there are very few moving parts servicing and reliability are second to none. As I said I ran a leaf for nearly a year plus I've researched and test drove most of the competition. Outlander is the best plugin hybrid in my opinion.
Give em a try. The safe mileage is based on normal driving. Eg you can drive at thirty mph for 100 miles or 100 mph for not quite 30 miles.
