How does extra weight effect range?

[PeteJ]

I am planning a journey of 315 miles and had my route and charging points set out but have now been told that there will be 4 adults rather than 2. how much difference will this make to my expected range? As my co-pilot is already in panic over range -this will be our first trip of over 40 miles - I would appreciate your experience.

Do you have ‘abetterrouteplanner’? if not give the app a try - you modify weight and many other parameters and calculate the journey.

 

[PeteJ]

Thanks, I will have a look

I have had a look at ABRP which looks very good but am unsure what the entry ' Reference Consumption' means. can anybody help

That's what you would expect to get as an economy (m/kWh, km/kWh) when you're driving.

Start the car, and use the down arrow to cycle to the dash to accumulated statistics, and it'll tell you what you've been getting as an average, and plug that in.

If you want to err on the side of caution, use a lower number than what the car shows. that let's the app figure out how far you'd likely get on a charge.

Many thanks for that info.

Good luck, depending where you are traveling there are limited charging options here in Victoria
(unless you are in Ringwood UK lol)

I am in Ringwood UK which is in the New Forest, very different from the Ringwood in Victoria which I have visited.

It will make a difference, but please also ensure you up the tyre pressure as that will help with your rolling tyre resistance, the manual recommended 42 psi cold for a fully loaded car.

Thanks, I had forgotten tyre pressures.

Just remember that’s cold so more like 44 psi once warm

42psi? The manual states 33psi when cold:

Yes - the manual is not great is it? If you look inside the drivers door shut the laden and unladen pressures are on a plate there - you’ll see Mark is correct.

Makes a big difference to mile per KWh, that’s the unladen or one driver PSI

Hi Pete, our experience will be totally different I would imagine to what your planning but our 'worst' consumption has been average 18kWh/100km here in Australia. That's on a 600 klm road trip fully loaded, 30 degrees temperature with AC on, highway speeds (80-100klms) travelling over the Great Dividing Range twice (elevation change of 780 meters each crossing). In summary we've found fully loading adds 3-5 kWh/100km in consumption. Here's a video of a different trip (look at approx 20:20 mark).

I will say one thing about weight! I picked up 400 litres of bagged compost for my garden last week, The drive back from the garden centre was way smoother than the drive to going there.
