Mitsubishi i MiEV range at 60 mph

24th June 2010 - What is the Mitsubishi range at 60 mph, in normal driving conditions?

Nissan have announced the distance they expect the Nissan Leaf will achieve with different driving conditions at different speeds. We are planning to do our own test over the next few weeks to see what the Mitsubishi i MiEV can achieve in real world conditions.

Today we have completed a drive on dual carriage ways including 'A' roads, motorways and using some roundabouts. The car was fully charged before we left and recharged fully on our return. We also used an energy meter on the recharge to see what the real energy use is.

I left the house at 10am after the rush hour had finished. The temperature was 19C or 66F. Although it was a warm day I did not use the air conditioning, but did have the window open a couple of inches.

The route I chose was using the A45, A46 and M69. There are a few roundabouts on route so there is some slowing down and accelerating. I only used Eco mode and accelerated slowly. The cruising speed was between 55 and 60 MPH, at this speed I was keeping up with the Lorries in the inside lane.

On my return home I had completed 63 miles with the charge indicator flashing on the last bar. The tripometer was showing 5 miles remaining. On a previous journey we have got the range down to zero and still been able to drive the car for a couple of miles.

The car is now fully recharged in 6 hours using 14.39 kWh. Our Electricity is 10.55p per kWH so the journey has cost £1.52, which is 2.4p per mile. Mitsubishi quote on their information 6p per kWh, this is the price of economy 7 tariff.

We will do the same test again in winter conditions to see how many miles can be achieved in colder conditions. We also plan to do a test a 70MPH and slower speeds driving through town.
