Where are you getting 0.7 and 80% from? Really, i am actually asking where those numbers are from, because I they seem very wide of the mark. Especially the 80% charging, what does that refer to?

What-car did a real-life range test, where they took 12 EVs across a broad spectrum of the market, charged them to full, and drove them as far as they could. The worst was a BYD Atto that managed 83% of its claimed range, the best was an VW ID Buzz that managed 92.5%, with most others being in the high 80s. All were vastly better than the 56% you appear to be implying here.
80% - I don't know about the Emeya specifically but in general EVs charging rate slows down the closer they get to 100% charged. So much so that it's generally reckoned to be quicker to stop charging at about 80% when fast-charging en route (i.e. the extra time of stopping again will be outweighed by the faster charging rate at a lower state of charge).

Charging Curve for the ID Buzz as an example, note charging rate tailing off above 80%


The WLTP test is conducted at an average speed of 29mph whereas most people do their long journeys on motorways/DCs averaging maybe 60mph. As power draw rises more than linearly with speed, efficiency and thus range on the motorway is lower than WLTP range by a significant factor, although annoyingly it varies by car.

As an example for the ID Buzz you mention, EV Database lists
WLTP Range 251 miles
Highway Cold Weather 150 miles
Highway Mild Weather 190 miles

so the average highway range (at a constant 70mph) is 170 miles, which is 68% of the WLTP fantasy number.

Usually the EPA range is more accurate. I believe it’s 200 miles for that which, given it’s done in warm weather sounds about bang on the money.

With China’s 1.4bn, ditto India USAs 350M Eu similar there are a plethora of wealthy potential buyers so why concentrate overly on the U.K.
This. It does make me chuckle when the denizens of the PH think the UK is the center of the universe for car demand.

The numbers Terminator is using is just finger in air random maths.
Probably works for the DailMail proof reading team tongue out
Seems a logical formula. Claimed range is known to be off from real world and of course, once driving like a normal human and not like a pensioner living on beans and stale bread so multiplying by 0.7 would seem about right and arguably reasonably generous. Then you have the general advice to not fill up to 100% all the time but to 80% to protect battery longevity. So that would give a fairer range through the year of 150 miles to work off.

This particular car is a very high performance GT so in reality you're going to absolutely cane the range so someone buying this and not panning to use it like Honda Jazz off to collect the pension is probably going to be lucky to see much above 100 miles on occasions and would be a bit dim to not factor that in to their decision.

Well Quite. It may well make a lot more sense to buyers somewhere else. I understand that rear seat room is a big deal in China, for example.
China did lwb versions of the 3 series and the a4.
Yep - my F34 is based on the Chinese LWB chassis. Loads of rear legroom, which is the main reason I chose it over the 4 series gran coupe. Rapidly elongating teenage kids who seem to be 90% legs. My OH’s ex’s genes, I’m the opposite configuration.

The MPG as stated by the manufacturer is absolute nonsense as it is for ICE as well. A more accurate figure is 0.7 of whatever the manufacturer states.

EV is then generally only charged up to 80% either to protect the battery or because that last 20% takes too long at a public charger so EV's are getting penalized if they try to charge into that zone.

The WLTP for my BMW iX40 is 264 miles - I’ve twice gone over this in the last 2 weeks. It’s not just me either - the iX FB groups contain many users app screenshots of range over the WLTP for both the 40 and 50 models.

Charging to 80% is guidance for day-to-day use. If you need to charge to 100% for a trip then you do it ! (Usable battery is less than full capacity anyway)

But sure, using your method - if you’re driving a 250 mile trip then charge to 80% and full throttle all the way clap

As usual from Nick that was a bloody hard read.

If the only two cars in the world were this and the Taycan I'd probably have it but only because it doesn't have a Porsche badge.
It’s probably because he writes like he talks and he must be one of those people who ums and errs and ahs, trying to gather his thoughts. It is fussy and unrhythmic; dull, plodding, and pedantic and not nearly so clever or stylish as he thinks.

Swap out the Y by moving the M, and add an N where the M was…

I think Tx may be confused with the 80% whereafter when charging the rate of charge decreases and the manufacturers headroom capacity which they prevent from being accessed. It just happens that some years ago that was also estimated at 20% hence the 80% figure. In 2024 the battery control and charging systems control charge rates to ensure battery life is not unduly impaired.

The 70% figure is just plain incorrect and a number of independent tests on many different EV give figures ranging from 82 - 93%.

Clearly it will be driver and condition dependent.

I generally leave mine plugged in and it charges to 100% of the available capacity to me. My range is about 80% of the stated range albeit the car is now 4 years old and 40,000 miles.

Ha! After two years with a Tesla (a bit quicker though - 60 in 2.5, not 2.8), that’s exactly what I’ve done biggrin

As someone who appreciates my EV as a transportation device, these things (hybrids included) just seem to merge into one. Usually a new C63, M5 or Lotus release would have me checking my savings, but in more recent times it’s got me reminiscing over classifieds.

Feel a lot of the "hate" here is from people who just wanted Lotus to carry on making a few lightweight Elise and Eviras. Financially, that was never going to be a viable option.
Lotus were profitable from 2016 with the Elise and Evora. The question wasn't about surviving, but whether they would continue as a boutique manufacturer of 2,000 cars per year or to try to pivot into the mainstream with volume.
No. They were profitable for a while but without long term sustainability. Other owners have tried to continue with "boutique" to no avail.

Geely needed to do something different. They've certainly done that... and now we'll have to see if it pays off.
