Efficiency over range

[LenEV2016]

Been saying this on here for a while, bigger and heavier isn't the way to go.

Forget range, electric car efficiency is what really matters for drivers looking to cut costs | Auto Express

Pete Baiden thinks the obsession with ever longer EV ranges is missing the point. More efficient EVs are what we need

Must admit, I tend to check out the range first.

Thinking environmentally efficiency is the key variable.

It also makes sense financially.

Where it gets a bit more complicated is that of course greater efficiency improves range as well!

The problem is that beyond a certain point it can be easier to get more range from extra battery than from (very marginal) efficiency improvements.

So OEMs stick in more battery capacity to attract those who worry unnecessarily.

I expect that as charging speeds increase and the charging network improves people will worry less about range and can focus on efficiency instead.

Glanced at the so called 240 mile range of the X Power, even though we know it won't do that, particularly in winter and thought, that'll do me. The X Power's party peice, was what I was more interested in.
The range was definitely a secondary consideration with me. Although I can certainly understand why range is a big deal, to some.

The thing is Tesla can give range and efficiency, so there are lessons there.

Nobody is getting range out of a battery like they do on the model 3.
The LFP standard range and rwd long range are about the best in the UK at the moment (range to battery size) and have been for a while

But at what price to the purchaser?

I'm sure the M3 is a great tool, the software integration with the supercharger network would make it ideal to travel all over the UK for work. I'm retired, my longest day trip is around 170 miles so well within my range summer or winter. When you charge at home ay anything from 0p (solar) to 7p (IOG) the efficiency of 3-4.5 m/kWh isn't a factor but the £10k more for a M3 does matter, plus I wanted a hatchback and the MY is just ugly (juniper is little better).

 

[LenEV2016]

But at what price to the purchaser?

I'm not advocating the M3 as the be all and end all, what I'm saying is if they can do it so can others but the choose not to.
As it says in the article the current trend is just to chuck bigger and bigger batteries in cars

 

[GaryMG4]

I suspect it is easier to add battery than engineer an efficient drive train and aerodynamics tend to converge designs in one direction. The original Ioniq had good efficiency and even our e-Niro can be quite good given its weight and bulk. The problem is they listen to the 'I won't buy an EV until they can do 200/300/400 miles' rather than try to educate people that just because you drive to Cornwall once a year and drive 20 miles a day the rest of the time you don't need a range of 400 miles.

I think it's from about £37,000 now, I hope that answers your question.

However, if as I suspect you may have implied, you want to include the manufacturers owners as an element, then probably a similar cost to buying Chinese state owned items, such as ....... but we wouldn't be hypocritical would we.

When I was thinking of buying an EV at first I thought about range. However, once I looked into the ease to find a public charger then range went out of the window.
My wife and I have had our MG4 LR Premium for just under 3 weeks. We drive it like we did the ICE car it's replaced i.e. air conditioning turned on etc.. and because we have only had the home charger fitted last Friday, no pre-warming of the battery, we are getting 3.8m /kwh, which I'm happy with. I'm sure as the weather warms up that efficiency will improve. Equally we could switch the Aircon off, but to improve the efficiency, but I see no need.

would be interested to see what their efficiency figures are in real life. i am always a bit skeptical of reported consumption figures especially when there is no way to verify the claim. I have infact witnessed a tesla m3 overreading speed and distance which made me wonder how many others do that and if it's by design or whether it's due to non-standard wheel sizes.
Eg i had a 16 year old skoda fabia, the budget version, which had a speedometer that would read exactly the same as GPS! running on the bog standard wheels.

There are many YT videos of range/efficiency for Teslas. I watch a channel RSEV, a second hand EV dealer, mostly Teslas but does reviews of others too, and does lots of interesting challenges.
A recent video is this one



but have a look at their 4 corner challenge too.

My MG4 speedometer reads exactly the same as the GPS, the E-Niro reads 3 mph higher than GPS at 30 mph. BjornNyland on YT does at lot of range efficiency checks where he drive the cars over measured routes to check.

The speedometer reading on my T-Roc is 1mph above the GPS and my wife's Polo which we have replaced with the MG4 was 3 mph above the GPS.
Not checked the MG, but will take a look.

As for Bjorn Nyland's YT channel, I have not been on there for a while, but @GaryMG4, thanks for the reminder about the channel, I will go and have a look at what he's been doing.

Ditto my SE SR speedo reads bang on GPS value .. also confirmed by several roadside speed indicators. (Easiest way to confirm is to find a clear, flat section of road, set the ACC to a given speed - e.g. 30 - and then track the speedo reading vs a GPS app, or satnav app with integrated speed indication).

Speedometer on my car is also 1mph above GPS at lower speeds.
