Wait for the X3

Presumably you mean the iX3?! If it is a 'conversion' of an existing ICE car (like the Golf; Leaf; Zoe?) then I am not interested. Which is my understanding so far but I may have the wrong end of the stick.....

I want to buy a genuine, designed 'from the ground up' EV (like the i3; I-Pace; any Tesla) which optimises all the space and format of an EV. I want revolution not evolution!

Up to this point, the only non-Bridgestone OEM tires available for the i3 are winter tires from Nokian. As far as I can tell, the i3 is the only vehicle that utilizes that size, so the market is limited. BMW, like most manufacturers, prefers to have alternate sources, but there is a limit on who will play or pay for the limited volume. As the car is on the market longer, and more have been sold, someone else may decide to take up the project but it hasn't happened yet, except for Nokian. Scandinavia has probably the highest proportion of EVs of any place, but China may be catching up...coupled with their severe winter conditions, Nokian saw a market for winter tires. Nobody else has for either the winter ones or those for other seasons.

Your 20" tires have 1" less sidewall height compared with the i3's 19" tires which could explain the tire noise. There's less sidewall to absorb pavement irregularities. Many i3 owners familiar with both the 19" and 20" tires have stated that the 19" tires provide a more comfortable ride.

There's only one 20" tire option regardless of where you live, so until a tire manufacturer decides to produce a competing 20" tire, no choices exist.

Brave new world for most of us: kW is a power unit, kWh is an energy unit. So your efficiency was 5.8 km per kWh.

The actual and usable capacities depend on temperature, how rapidly charge and discharge occur (i.e., charge and discharge current levels), and how well-balanced the 96 battery cells are in terms of capacity, charge level, and internal resistance. BMW states the nominal actual capacity as 33.2 kWh with 27.2 kWh usable. Some feel that the usable capacity is greater than 27.2 kWh under many conditions. You might have a battery pack with exceptional battery cells.

Thanks Art - useful stuff.

Incidentally I felt that the demo i3 on 19" wheels was no better than this car on 20" wheels. Indeed I was surprised that the ride still seems fine - quite acceptable to me but I like a 'firmer and talkative' ride....

Now I have filled the i3 with heavy rubber mat just about everywhere I can fit it, I'll just have to accept the tyre noise - already my ears are cancelling out the background noise a fair bit. The difference between smooth tar noise and the rougher stuff that we have all over the place is night and day.

But the Harmon Kardon sound system helps in this task!

If we've got excellent batteries, I'll not complain. Already with the range I'm getting (and the Rex as back-up) allied to the journeys we do, I am over range anxiety.

I'm going to do a set of T-shirts - "Electric Cars - just simply better". Can't believe the amount of EVangelising I'm having to do - there is far more awareness and curiosity than I imagined - even here in darkest Afrika.....

Our i3 is back home with tinted windows and the roof rails blacked out - looks great with a 'black top' and the tinting helps with the hot weather we're having - 28deg C in mid winter - crazy.....

Enjoying it more and more as I get into the swing of it. A small query to other drivers - I have read some comments about the handling/steering being a bit skittish at times and I find this too.

One thing I notice is that the steering does not strongly self-centre so the steering is a bit dead at straight ahead so the car can wander or dart a bit (particularly over a bit of broken road) This could of course be due to my tracking alignment being slightly out,

Anyone got any more helpful observations!?

I always blamed the skinny tires for the handling you describe

I don't think skinny tyres per se should produce that effect. Has anyone tried increasing the toe-in at the front a touch to enhance self-centering and directional stability? May reduce range minimally and increase tyre wear.

Another query! Petrol certainly goes stale if left for a long time and it seems that the petrol in our i3 may never get used - will this result in poor quality petrol that may be problematic when the Rex does (eventually) have to kick in. Should the petrol be drained or deliberately used up on a regular basis?
Thanks Guy

If the wider tires are still unique to i3 and more specifically i3s[2018], they will be even harder to find. Just a thought.

The best value will be the 2015. Best balance between available warranty and price. As far as how it ages? The car has remained virtually unchanged since it was released in the USA in 2014 and 2013 elsewhere. Not sure about the situation in S. Africa, but the USA leases are typically 3 years which is why we have so many 2015's available as lease returns, making it the best value as inventory surpasses demand by a substantial amount.

I don't know about the market where you're at, but in the USA, people were sitting on their hands waiting for the "cheap" Tesla that never came. So potential demand was high, but actual demand was low which helped keep the prices on the used i3's further down. The range is is rated at 72 miles give or take 15-20mi depending on how you drive it and what mode you're in.
