250 miles.... NOT!

[Deleted member 7134]

Just picked up Whitey-Excitey LR and manged this on the way home from dealers. Obvs I was driving very carefully, but driving at speed limits, in Eco with Kers2, no heater on, 5°C outside. So I reckon 200 miles would be possible, based on what GOM said, and my driving style.

 

[Deleted member 7134]

Trip now at 20 miles and 90% (so still on track for 200 miles perhaps) and that included a bit of 'zoomies' in Sport but didn't last long as SWMBO said it made her feel sick

This may interest you about EV range reduction in winter..

This may interest you about EV range reduction in winter..

I'll have a look, thanks.

There range or MPG is equally affected in the winter time.
But because you are carrying such a massive surplus of fossil fuel around in the tank, you don't notice the decrease in efficiency.

I was horrified when I discovered that the fantastic mileage promised on my Diesel was nowhere achievable when I picked up my new CRV in March about 6 years ago. I discovered Diesel efficiency falls off a cliff below 25 Degrees C. All WLTP testing for Diesel cars is done above 25 Degrees C

in the warmer months i use 10% battery every day to and from work in the winter months i use 15% battery per day with heaters demister and heated seats on not bad i think

Why do people believe that they can get anywhere near manufacturers figures in ICE or EV? When I bought my combo van 4 years ago the dealer made a big deal about it being able to do almost 60mpg. My reply was not a chance in hell I will be lucky to get 35mpg. It turns out I was pretty accurate the best I get is 38mpg and the worst IV had on a journey was 25mpg.

The WLTP figure for the SR MG5 is 214 miles, I could beat that easily in Summer but won't get anywhere near it during winter.

I think I’m still getting about 170 on my standard range. Upgrading to a long range this week, it’ll be interesting to see if it suffers more from the cold compared to the standard range as some people seem to be suggesting.

My qashqui has done 36,000 miles, 1.5 diesel 2018, the combined mpg on the odometer withou ever been reset is 62mpg, I don’t think that’s far off the official rating. I worked out it ran at about 10p a mile, with the mg5 been 1.2p a mile if I charge between 12:30 and 04:30 and about 3.5p a mile at all other times.

The difference is that ICEVs already waste 80% of the energy in the fuel. An extra 50% energy to the wheels doesn't require 50% more fuel to be burned.

Because EVs are so much more efficient, the losses in winter are more directly translated to extra energy being taken from the battery.

Yesterday, motorway driving at 60mph, heater at 20C in 4C outside, MG pilot, heavy traffic.

Drove 100-10% in an out & return trip giving an effective full range of 184 miles in a LR

What was your total travel time?

Hmm, I was always told that ice cars prefer cold, dense, winter type air. The combustion cycle has more air to mix with the fuel so you get a bigger bang for the buck! All the other factors go against both types of car though. Road condition, wind, rain etc.

With ICE diesel or petrol you get slightly more power with cold dense air and theoretically a tiny increase in efficiency ( depending on how the engine management systems and sensors work together ) but then on short to medium journeys you have a massive lump of cast iron or alloy to heat up from near freezing which wrecks the economy. My old jeep (3.0v6) did 25-28mpg ( ouch! ) on warm days and 15-20(!) on cold days ( aargh! ) . Defrosting the jeep and running the first 5-10 miles only returned 10ish mpg. ( help!!!! ). The only energy "wasted" in the EV is that used to get the cabin warmed up. Something to watch out for is having the circulation fan too high otherwise your sucking in more cold air that needs more warming up. Makes a big difference to m/kwh. You do realise that owning an EV can make you into a total nerd even if you were nowhere like that to begin with. I'm probably only a few small steps away from gluing myself to a road somewhere.

When I first got my previous car (diesel) I became obsessed with trying to get over 70mpg on my 45 mile commute to work. It was like a challenge I had to complete. I did it in the end though (in the summer)

No doubt I'll be just as obsessive with this EV

 

[EVsince2016]

What was your total travel time?

It should have been 1.5 hours each way totalling 3 hours but due to a police incident I lost 45 mins out and 1 hour on the way back. Sat for an hour in traffic cost 2-3% alone!

My 2001 Diesel quoted at 55mpg. Average MPG obtained = 54.5 mpg
My 2008 Diesel quoted at 49.5 mph. Average achieved = 36 mpg

2016 30kw LEAF quoted range 107 miles (EPA) ignored NEDC - average range at 4.0 miles per KW = 110 miles
2018 40kw LEAF quoted range 151 miles (WLTP) - average range at 4.0 miles per kw = 152 miles
2021 MG5 LR - so far 184 miles range average but it's winter, estimate achieving only 220 of 250 miles range

 

[5teep]

Did a 70 mile run today in 0c or near temps and really bad weather. Sparing use of AC and heater got me 162 miles equivalent range on my SR, average speed 48mph.

 

[SachaF]

Had my car (MG5 LR) for a week now. I've been playing around with kers and driving style a little on my commute of 20 miles, which is being done at 3-5°C with a cold car. Using heated seat, finding kers 1 with a smooth drive is more efficient, I am using about 10% for 20 miles now (20%/day) as I am more familiar with the car, so this would equate to nearly 200 miles which I am very happy with. A mixture of 30/40/traffic queue/60, rural and semi urban driving.

There range or MPG is equally affected in the winter time.
But because you are carrying such a massive surplus of fossil fuel around in the tank, you don't notice the decrease in efficiency.

Absolutely not comparable - while an ICE also loses some fuel efficiency mostly due to friction losses of colder fluids, an ICE always has a big surplus of heat that can be used for heating the cabin - in other words, there is no additional fuel burned for heating, v.s. the EV, which must 'burn' lots of energy to heat the cabin.
Moreover, gasoline does not need pre-heating, does not lose thermal output like a battery. All things considered, ICE are by far less affected than battery powered cars in cold temperatures - it's simply one of the disadvantages of EV's.
