Driving to work today it was mentioned that VW had announced that they would stop development on combustion engines around 2024. By then there will be advances in technology which will, no doubt,overcome the distance limitations of a all electric car.

I wondered, though, how the performance of an electric car compares with a diesel.

Example - I tend to corner in a low gear so that I can accelerate once out of it. I've got a diesel and it pulls away sharply out of the bend - which my wife's car struggles to do so.

What is the experience of those with pure electric?

Also, what about heating in winter - how does that work?

If you like the low down torque of a turbo diesel, then you'll be just fine with electric - just check out one of the millions of Tesla videos online.

Electric cars have insane torque from 0rpm, they don't require gears at all they have so much torque. That's why the Tesla is the fastest 'normal' production car in the world with a 0-60 of ~2.3 seconds.

Most EVs use a heat exchanger for heat, taking heat from the outside air (down to about -20) and also using the heat from the electric motor and finally a normal electric heater. Uses about 5-10% of the battery in winter.

What do you mean? Most have a heat pump now to warm the car relatively efficiently (compared to a fan heater), but yes you will still lose some range.

Some can pre-heat the cabin automatically when plugged in overnight to save having to warm the car up using the battery in the mornings.

Consider an electric motor to be around 85% efficient, compare that to an ICE.

We have a Model X P100D, which is the big people carrier. Torque is absolutely instant. It's not far off my motorbike in terms of throttle response at pretty much any speed, but especially below 100mph.

I'd wager there isn't a diesel anywhere that goes faster at any point sub 100mph.

Re heating: It has 'normal' climate control, heated seats (all six), screens and wheel. It doesn't seem to significantly impact range.

If you have a local dealership for Leaf, i3 or Tesla, just go and have a drive of one

Physical answers to your questions right there waiting

Available torque and / or functionality of heater will not disappoint you. I am pretty certain of that.

When I tried out the sister's Leaf it was quick round town but fairly gutless out on the open road, kind of the opposite of where I'd want the performance, but YMMV.

Maybe.

But, do you think any Govt. or local council will be able to put the charging points & infrastructure in the next 5 years?

Lot's of the UK looks like this.

Its well known that the grid is already at capacity and that it isn't possible to install enough charge stations for every single car on our roads but its also highly unlikely that every single person in the UK is going to wake up one day and scrap their ICE and get an EV... However, as much as people might think it, ICE are not going anywhere any time in the next 50 years let alone 5. I think that what VW are saying is that they won't be producing anymore 100% ICE the near future is definitely very focused on Hybrids.

I've got a 4.2 twin turbo V8 diesel, it can't keep up with my mate's Tesla...

Absolute rubbish. Grid can support 24million EVS *today*. They released a pamphlet on their website to try to stop stupid made up posts just like yours.

There's a nice little site here: http://www.gridwatch.templar.co.uk/

While it looks like w're close to max demand, wind drops off massively sometimes and CCGT (Gas) takes it's place. But also bear in mind we can import/export as per the line graphs on the right.

"They" being the environmentally friendly hippies that actually believe EVs are better for the environment than a normal engine?

Believe me if 24 million EVs were to suddenly appear on the road tomorrow our grid would not cope. We have a buffer of around 20GWs currently between what is reliable energy and what is used at a daily peak so tell me mathematically how the grid could support 24 million evs?

Also, don't forget there is a difference in stopping development and stopping production.

What we can read from that is that from 2024 the combustion engines in play at that time will be used for however long ICE continues, maybe with a tweak here and there. And predominantly in the form of range extenders maybe.

I think what VW actually said was that they will develop no new platforms capable of taking an internal combustion engine after 2026. I rather suspect they mean no new platforms capable of taking an ICE connected to the wheels though, I can't see them going pure electric final drive without some form of range extension in that time-frame.

Of course if they release their last ICE platform in 2026, that'll realistically mean they're still producing ICE cars until the mid 2030s at least and it'll be the mid 2040s by the time most of those cars are retired from the road. That time-frame sounds about right for the death of pure ICE and mild hybrids to me.

Umm, no, "they" being the actual National Grid.

I don’t because you are not right, and mixing up grid, power generation, adoption rates, grid-flex, numbers, demand and whole load of other stuff. I guess you’re new around here as this a well-trodden path in the EV vs ICE debate - I can recommend you try the search function.

Requires 30GW, peaks at 60, according to DUKES capacity is 81GW including wind solar and hydro...

Also don't see where it says 24 million anywhere in that paper
