The all things EV chat thread

[Tashyboy]

Falling outta love with the CX5 and Ave seen the Lexus UX 250h hybrid. I think the hybrid tern is very loosely described, however the mileage is very good. How I never came across that car when looking a year ago is beyond me. Maybe the Lexus badge made me think it was outta my price range.

Possibly, but I've not heard of losing lots of range in an ICE when loaded up. Can Bunkermagnet confirm what happens with his diesel van?

A full tank of fuel only weighs about as much as one person, so that seems a minor factor compared to loading a van up with lots of stuff.

The thing that affects my van mileage is how hard I press the loud pedal.
How much load 8 have doesn't seem to make any difference.

Do you think there is a stigma on t6 plus tradies having higher end tools?

I had a Kia ceed as a pool car back in 2012 and other than cheap seats for long mileage, the car was bullet proof.

I dont think there's any stigma to owning a VW T6. I would say the VW"s have progressively become less reliable as they've developed.
The biggest thing about the Transporters up until the latest Transit collaboration is their security. Aside from the glass, you wont see a Transporter with holes punched through the doors to disable the locks and alarm.

Can anyone explain the physics of why adding load impacts range so much more on an EV than an ICE? I just can't fathom why.

I didn't know this; I did a little AI research because I was interested...

Average electric van battery is about 80kwh.
Average diesel van has a 70 litre diesel tank. 70 litres of diesel produces the equivalent of about 700kwh, most of which isn't converted into mileage.

Electric is very efficient.
Diesel is massively less efficient but there is a huge buffer of wasted energy that can be used to shift a greater load without impacting so severely on consumption. Electric just doesn't have that buffer.

But that is the same as having four bags of say cement in a van.

Not range but performance- I have had cars that I noticed the difference with a passenger in the car.

I used to drive a 2.5 litre diesel Transit and used to notice the difference when it was loaded up when we went on holiday compared to me driving around on my own but too long ago to tell you what that difference was exactly.

Anecdotal...

Most of the mileage in my BMW 520d is just me on my own without luggage. It averages 50.7 mpg.

In the summer I went away with a couple of pals so it was carrying an additional 2 adult males, 3 sets of clubs, 3 trolleys and luggage for 3 days away. It averaged 50.4 mpg.

No argument that electric is way more efficient than ICE.

But the highlighted bit implies that a diesel engine gets more efficient when it's hauling a bigger load. That makes no sense; I'm not buying it.

It doesn't. It's just largely drawing on some of the 90% of energy that is otherwise being wasted.
Whereas an electric motor has only a tiny amount of wasted energy so the extra energy needed for dragging the extra load is all coming out of the battery on top of the usual.

Please do get one and then review it. I'm not looking to change my car yet but when I do this is one of interest. You can give a golfers review

If that is true, then it's precisely the definition of getting more efficient as the load goes up.

But I don't believe it's true. If a diesel engine is wasting lots more energy when it's not hauling a big load, where does that wasted energy go?
