OK, so I now admit I have moved to the green (or is it blue?) side with a car with no tailpipe emissions, and indeed, no exhaust pipe.

The little i3 appeals to me as it is still the only composite mass production car. I have been working with carbon race cars since the mid 80’s and I understand their advantages, but cost has always kept them from the mainstream until BMW’s pioneering work. They built over 200K of them from 2013 to 2022

Like my wife’s taste in music, her taste in cars has been very hard to pigeon hole. From Mini to Lexus and SLK to Defender, the one defining factor has been a certain quirkiness. Good experience of both ML and GLE led us to an X3 BMW, but whilst there was nothing wrong with it, she just found it a bit ‘meh’

The i3 I picked up from Canterbury yesterday is just 2 years and 5k miles old. I’ve had new cars delivered which have been in worse condition and the description ‘as new’ really does apply to this one. Both the sale and handover were seamless and the young sales guy was a motorsport nut, which helped.

Range anxiety was dismissed over the course of my 155 mile journey back to Norfolk, as the more I drove, the greater the range diverged from the distance to go and I got back with 65 miles still ‘in the tank’

The throttle pedal has 3 ‘zones’. At the top is regen with up to 0.3g braking, then a small coasting zone like having the car in neutral when on the move, then press a little more for instant go. It must have taken nearly a mile to get used to, but then I touched the brakes only once over the rest of the journey, only thanks to a lane swapping white van man.

Over the last ten miles I got to let the car off the lead on the quiet Norfolk roads and found a real sports car! The low weight and low centre of gravity coupled to instant access to huge gobs of torque, makes the car a real hoot to drive. I laughed out loud on the exit of some tight bends as the little car shot out of them with just a spot of TC to keep the rear tyres gripping. A proper little roller skate. I wasn’t expecting that much fun!

My wife had a short run in the car before I put it in the garage overnight to charge. 170 miles and it has cost less than a tenner to fill the ‘tank’. About 30% of the fuel costs of the Macan diesel. When was the last time you filled up for £10? I think it is 30 years ago on a short range motor bike for me!

Welcome to my composite world! The shell is strong enough not to require a 'B' pillar.

Memory seats are but a memory in this lightweight car, so markers on the seat rails help define positions for Mr & Mrs.
That's a throttle pedal Jim, but not as we know it.

As new!

Quirky, yes. Pretty? I don't think so! But then that's not why I buy them.
 
With the ‘range extender’ an EV I’ve actually considered. Good choice. 😎
The Rex became extinct in 2018 when the bigger 120 Samsung developed battery came on line. This doubled the range of the 2013 launch car.
I don’t want to carry 125kgs of ballast about and have energy converted from one form to another inefficiently . To me it’s neither fish nor foul, but I understand why they did it at the start as a sop to the underwhelming range.
 
Looks good.

Is the boot big enough for a Flatcoat retriever, effectively the same size as a Labrador, and hopefully SWMBO's Cockapoo?

Probably not. We have a Border Collie and a Pollie and intend to use our dog hammock in the rear seat area to give them space.
We used this system successfully in the Audi A8 when the we had the Collie and a Border Terrier. Not much good if you need to use the rear seat for other peeps though!....but it does leave the boot free for luggage!

I suspect they were too expensive to make [ =not profitable enough] for BMW- a great pity-people are not going to be converted to electrical propulsion en mass till someone brings out the EV equivalent off the model T ford to bring them more within reach--signs are manufacturers are going in the opposite direction-bigger/heavier/ more complex /expensive instead of smaller/lighter/simpler/cheaper :(
 
They are a great little car as a local runaround. A mate has one for his wife. School run, shopping, ladies that lunch it’s the perfect solution.
If I were you I’d ditch the virtue-signalling green flash number plates. They don’t match with anything else on the car. Then, for me, it’d be perfect

Yep, as soon as the V5 comes through the post, it will be on my wife's private plate....without nasty green blobs! Hope that will suit!

Yes, quite right and the very reason I have got one now as they represent great value at less than half RRP, still in warranty and enjoying the technology the BMW must have spent billions on. The VW ID 3 is half a tonne heavier than the I3 :eek:
 
The i3 is on my list of cars I'd like to own... the only leckie car on it. For the same reasons you bought yours.. I do like the styling.. and the fact its actually lightweight for one that runs on juice. Too many cars in my fleet at present... but maybe someday. ;)
 
The i3 has always interested the engineering nerd in me. A few years ago I drove one of the range-limited ones that was run as a company car by a colleague in Holland. It was fun to drive but the combination of (very) poor range (ISTR not much more than 150km) and crashy ride put me off. It promised much, but - for me - back then it didn’t really deliver.

I see that the range has been improved significantly. What about the ride?

The ride is not the car’s best feature! A little brittle. That said, it is no worse than the X3 it replaces. I’ve gone down just 2psi on tyre pressures and there is an obvious improvement.
As the car is unlikely to be driven at constant autobahn speeds fully loaded so I shall continue down that route until I see some negative impacts. I’m sure there is more to be had.
Not really in the same league as the air suspension in the Macan, but for scuttling around Norfolk, it’s quite tolerable.
 
An i3 is top of my list for when my W203 succumbs to rear subframe rot (it received its first MOT advisory this year). It won't be a newer one, probably a post 2017 with a 33kWh (120 miles) battery, and as they nearly all have the range extender it'll probably have one of those too.

I'm in two minds about the range extender. If used frequently then would I be better off with a 'proper' hybrid, or maybe a different EV with longer range (Leaf Gen 2)? If I rarely used it then why have it? From the figures it's not even that frugal, around 40mpg when running. BMW do recognise it may never be used and have coded the occasional run up when battery capacity will allow, just to keep everything lubricated and drive off condensation. I assume the 650cc two cylinder detuned scooter engine is subject to all MOT emission regulations?

I do like the i3, though I'd have the back seats down and treat it as a two seater to carry my golf clubs and trolley. That's if I could fit a home charge point. My car lives under a carport at the bottom of the (shortish) garden and the electricity meter could be further away, at the opposite end of the house.

I was all set to get a charge point fitted, but I’m going to hold back for a little while. Two reasons, no installers have yet got back to my inquiries, but mostly because it charged happily overnight on its granny charger. It pulled a max of 1.05 kWh and had fully charged prior to 7am.
That’s a similar usage as a 1 bar electric fire. Whilst an extension cable is not recommended, a heavy duty one (uncoiled!) will happily run at 5 amps to where ever you need.
Unless you are doing long distances every day, I question the need for one with i3. If you were taking twice the ‘fuel’ on board as a larger EV can, then yes.
I expect to be plugging in overnight about once a fortnight with mine unless the car becomes much more used than anticipated🤫

Thanks Mac, that's very useful information. My usage would be very light, mostly five miles there and back to the golf course once or twice a week and to pick up a curry or Chinese now and then, although we've starting doing return trips to Sevenoaks about fifty miles away to see new granddaughter, which would be pushing the real world range. The only thing bugging me is I'm occasionally the taxi driver for Mrs. Stratman's 'away' marathons, but I'd cross that bridge as and when.
Thanks again, very informative and encouraging.
 
On a different point, how do the clamshell rear doors pass safety regulations? As far as I can tell they can't be opened unless the front door is opened first. This has to be a concern for getting people out in a hurry, or if the front door can't be opened at all.

The i3 was clearly designed as an electric car with little compromise to make it conform to IC car fashions. I remember that I admired it when it was launched: high tech construction giving relatively lightweight, large diameter wheels and narrow tyres to reduce rolling resistance as much as possible. These are features that all EV's should have if they are serious about reducing emissions. That design philosophy didn't last long with EV's gravitating to the fashionable inefficiencies of excessive size, performance, weight and the usual wide tyres. EV development has been sent in the wrong direction for the simple reason that only the well off have been able afford them and those customers were not prepared to compromise on the fashionable elements.

Apart from the i3 it's hard to think of many other EV's that took the design brief as seriously.
