Couple of articles looking to Australia, which has an appalling rollout so far of BEV's, but looks like things may start to change soon.

Also one article is kinda funny given how many people still think of BEV's as slow, but when it comes to ill-informed critics - torque is cheap!

It's not what you drive, it's how you drive it

The latest (I think) MAZ buses are hybrid, and very quick off the mark, as discovered on one of them last year.

Just some throwaway energy figures for a couple of drives I did yesterday. Thought I'd post them as they start off quite interesting (scary). [m = miles]

So, popped out about 10am, it was very hot but the sun hadn't directly hit the TM3 yet. Forgot to turn climate on before I left, so at the 0.2m mark the car was blasting the A/C and showing 1,000Wh/m ...... Holy Cow!  It quickly settled down to 300Wh/m once I'd finished pottering at local shops and suburban roads, and hit the 40-50mph sections, then slowly and steadily dropped down to 213Wh/m at the end of a 22 mile circuit.

Then in the evening Wifey and I popped out at 6.30pm. Again forgot climate, and the car was in direct sun, so switched it on 1min before we left, so again started high. On dual carriageway at 50mph it was slowly dropping from 600 down to 300Wh/mile when we hit the M4 (after ~4miles), then (for once) I drove gently at 70mph and it slowly dropped to 256Wh/mile after 24 miles. Left restaurant around 10pm, still hot, but no longer HOT, so with Wifey driving and sticking to 70(ish)mph, we got home with a total of ~48miles and 236Wh/m.

Goes to show the impact of heating/cooling the car, and my inability to remember to do it in advance, especially when the car is plugged in. Doh!


Edit - Just to say, the figures I've given are running averages, hence they start high with high consumption from A/C and low distance to 'spread it out over', then steadily fall over time and distance. M.

Interesting figures Mart, 1000Wh/m, Wow that's a scary consumption to learn of.

Have to confess that our black Leaf being out in the sun on the drive does get hot at times too. While I've set climate control in winter to warm up while plugged in I hadn't even considered doing the same in summer for the opposite reason. So good thinking on that point. On the other hand, after getting in, I do just tend to lower the front two windows for a mile or two before closing and then switching on CC.

You say "scary" but it's similar to my ancient Fiat Panda both financially (13p/mile, more or less) and with carbon dioxide (233g of CO2 per kWh of electricity, 230g for 1/10th litre of unleaded). And you get to drive a Tesla not a Fiat Panda

Not sure of the weight differences vs the Ioniq, but those are very similar motorway numbers to the Birmingham trip, most of it at a steady 70mph the average was around 290Wh/mile with the window down a crack (downside of being a smoker).

I'm more interested in how it will cope with the winter commute (it's doing roughly 2 days on 85-90% of the battery, commute is 44mi one way, motorway then A406, occasionally with the M25 and A1(M) thrown in making it slightly longer), but it seems efficient enough to do this, even if it needs to be plugged in every night when getting colder.

Yes, my mother was interested that £3 can run a car for 170-ish miles as she thought her car was cheap to run. She drives a Chevrolet Spark

Just a guess, though I may test it out at some point, but I suspect our 28kWh Ioniq would have done that shorter journey of 22 miles at something like 5.5miles/kWh or 180Wh/mile. Again, only a guess, but driven smoothly and avoiding 70mph+ roads, the Ioniq is incredibly efficient.

Regarding weight, the TM3 LR is 1,847kg, whilst the Ioniq 28kWh is 1,429kg (the petrol car was 1,370kg and the PHEV was 1,495kg).

But I bought my Panda brand new for £5950 plus a knackered old Land Rover.

Somewhat cheaper than a Tesla.

That's some efficiency (meaning the TM3). A joint venture partner has a Y arriving imminently (in a LHD-only market, I believe it's coming from China but am not sure whether EU versions will be too), so I'm interested to see one in the flesh even if it isn't styled in a way I'd go for (plus the various data collection issues I personally take with the company).

My commute isn't that efficient, that's granted. It'll still be more eco-friendly over the life of the car than something diesel-powered.

Looks like they have copied this park and ride in Stirling, with a paltry 32 chargers, vs Oxfords superior 38

https://www.stirling.gov.uk/news/2020/august-2020/works-begins-on-castleview-solar-panel-transformation/

Though the Stirling ones are mostly 7kw chargers... and mostly powered by solar, which to my simple mind seems a far better solution for a park and ride.

Motorway stop, you want the rapids, park and ride... eh?

Edited to say I have actually used the rapid chargers here about 2 years ago, before this creation, and did note about 3 months ago, its pretty well on.

Hopefully open soon for charging on the return from Dundee or Aberdeen 

Double edit, they are still showing only 3 devices on zapmap, but the picture gives an idea of what it's like

I swung by this park and ride in Stirling today. 
There are now 4 x 50kw chargers... unfortunately all of them being used when I was there today, but loads of 11kw standing chargers, and the solar panels would have been doing very well today
