Then again, you are a nutter and probably have Mugen wheels on it by now.
I made enquiries with Mugen shortly after I picked mine up--at that stage, they unfortunately had no immediate plans to release parts.

Chris.

Shouldn't even have joked about it!

How far can you go on roughly a gallon of squirt, then?

I don't really know for sure Nick as I've never driven it that far.

I only use it for short journeys, which usually involve 70+ mph dual carriageways that eat the battery......plus I rarely drive it economically, the instant torque/rear wheel drive combo is too much fun. I do use the paddles/regen quite a bit, but don't usually drive in 1 pedal mode--that has the most regen.

When it was warm the on board computer reckoned it had around 110 miles of range. Now it's cold (<5°C), it shows around 70 miles--if you keep it plugged in and pre-warm before you head off then the range goes up into the 90s.

On average, I would say 1% battery charge roughly equates to 1 mile range.


Chris.

That's interesting, Chris - thanks.

Given that I'd probably drive one like you do, I'd be interested if I could get down to the sort of disappointing figures I get out of say, a Jazz.

If your worst-case scenario is roughly 70 MPG, it nicely demonstrates the sheer mechanical efficiency of the heavy little thing.

I've seen studies where using one-pedal does reduce efficiency by 'over-braking' and use of paddles is probably the smoother, more consistent method. Perhaps counter-intuitively.

I've just checked and I've driven 983 miles so far, which has used 384.9 kW/h and cost £57.73 according my charger (although the car currently has a full charge, so you could add 70-80 miles).

I'm not on any fancy low tariff electricity either, just a general variable rate.

Charging overnight on a 5p tariff would reduce costs considerably, probably would work out at less than £20 per 1000 miles.

OOI have you driven the new Jazz with the half hairdryer engine yet Chris? If so, any data on mpg on those?

By way of contrast my 485 miles has used 135kWh at a cost of £7.79 for charging. I mostly drive like Scrooge on country roads locally with very little DC work.

I have been on the 'fancy' Agile tariff from Octopus (wholesale market tracker) for years and for most of that time with a 9.6kWh house battery (plus PV for ten years). The energy used by my 'e' is noted but it is small enough to be absorbed into the overall house budget of 4,500 to 5,000 kWh - the cooking for example uses four times as much and the fridge/freezer about the same as the 'e' at this rate. Mid term, my objective is to somehow make the 'e' battery an additional house energy store, but only the Nissan Leaf is V2G at the moment I think (but there may be others.) Honda is working with Islington council providing chargers for it's little fleet of Nissan e-vans as we speak. The 'e' is not V2G compatible but does have a 230v mains supply outlet in the console

The house, which I see as dominating our energy consumption, was built by me and is grade A (EPC) energy efficient. Passivhaus was too much of a leap financially although my architect pioneered them. My partner could not have survived living in a Passivhaus, she who flings open all the windows in spring! But it is exclusively electric powered with a ground sourced heat pump providing space heating via UFH and DHW heating. Solar hot water as well as electricity (PV). Wood burning stove for if the grid falls over. The house battery controller has an Emergency Power Supply capability which can drive the utility room, fridge-freezer, kettle, microwave and cooker plus a few lights. Push come to shove I can run a lead upstairs to power the wifi router.

Sorry a lot off topic there perhaps but just to give some background to my holistic but pragmatic approach to the green issues.

The moho and Smart car are our last burners of fossil fuels apart from the stove.

Sorry afraid not 'fester, haven't driven the new Jizz.

My Mum is contemplating updating here ageing Jizz with a new one, so might have a chance to drive one in the future, but probably not until the current unsavoriness settles down.......

So c2.7mile per kw or avg 95 miles per 35.5 which is sub £5 so over 100mpge. Not as good as Rog at 300mpge

A quick jazz doesn't really exist anymore but combined mpg is a probably not realistic 62.8 and its more complex and still weighs 1200kg+

plus it's front wheel drive, though the last Jazz I drove was ok (first and second gen I didn't like at all)

(Cheers Chris)

First and Second Gen had weird weighted steering. We're on ( well she is ) the 4th or 5th one now. The problem is the new one is 23k for the 'nice' one and it's not better enough than the outgoing one unless by some miracle the powertrain is massively pleasant. Allegedly the media systems are better but the better ( really better) one is in the CrossStar which is just plain weird.

There's the 130bhp outgoing 'sport' thing which is probably a bit better as the 99.99999675bhp powered one needs it's knackers kicking to keep pace with stuff.

I am sure we'll test drive one eventually but same as Chris, not until the current issues have gone away.
