Well, it seems like electric cars really are beginning to make sense rather than just being an eco-showoff...

https://www.theregister.co.uk/2013/11/12/review_bmw_i3/?page=2

Equipped with the REX it can manage a combined cycle of 470.8 mpg! Now, as soon as BMW bow to public demand and put a proper sized fuel tank on the thing (rather than the 9l it can hold) it'll actually be a viable electric driven car with the option of saving a few quid on the commute too.

i8 looks like it will be even better. I'm waiting for the iz4 though Smile

<edit> should add that the REX is an on board 650cc engine as everyone so far seems to've missed that point...

MPG is a pointless figure on these...

What they need to show is how much it costs to charge the battery from flat to full at the current Kwh costs.

Now that will scare potential owners off..... Laughing

pointless doing 500mpg if your range is 70 miles and an 8 hour re-charge (for example)

unless i missed it, it doesn't mention range at all..

Agree. They all say, just simply plug it in and away you go the next day. I "simply" plug an electric heater in and my meter goes into superfast spinny mode, what would it do if it was charging my x Ah battery everyday?

BUT you get 500 miles per gallon of electricity Smile

In fairness I love the idea of a motor powering an electric motor, no need for heavy expensive batteries, just let a motor idle away giving all the charge a motor would need. Then that's still relevant for MPGs. If this starts cutting petrol usage though, we'll have to expect the price at the pump to shoot up so they all still get their profits and taxes to similar levels.

The REX is an on board 650cc motor so the mpg does matter...

£3.52 to charge based on BMW's figures and 16p/kwh charges

"between 80 and 100 miles on a charge"... that does beg the question of 470mpg on a combined cycle. Even assuming 100 of that comes from stored charge:
9 litres is almost spot on 2 gallons.

That means 100 + (370*2) = 840 mile range! Surely not !?!

I join in the questioning of the 470mpg now!

But what does that 'warranty' cover?
I doubt it covers the battery losing charge from use and I expect daily high use could easily see it expiring before 8 years.
Or, you can unintentionally let it run out of power and as per the Tesla, be liable for replacement cost.

Need to consider not only cost of charging, but the extra depreciation as the battery bank gets used. Not sure if that warranty will transfer to the next owner too, which may drastically reduce it's resale value.

I'm not convinced about the figure too - I wonder if it's a case of, say, a 120 mile drive where the ICE fired in for 20 miles and they worked it out from that.

I do like the idea of a petrol-electric hybrid. Especially one where you can remove the ICE for daily use to save weight and space.
However, I still wonder if for longer journeys, it'd do better on economy for the ICE to be directly connected to the drive chain to avoid losses.

I'm sure the technocrat class with a fuckload of disposable income and eager to score some green cred will lap up the prospect, but for the average Joe that gets by on cheap used cars to get from A to B, sinking a shitload of money up front on a battery that may pay off in a number years is a total no go.

And as far as warranties go, they're usually not worth the paper they're written on. Did you go to your authorised dealer to get regularly buttfucked per hour for the required service at the required interval? No? Then the warranty is null and void. Go get fucked is the usual response.

Dream on.

I believe the warranty is like most of the others... once it drops below a certain percentage of charge it gets replaced. In the US they require it at 90% for 8 years or 100,000miles so it'll be similar across the globe I expect.

Efficiency is an interesting one. How many drive trains have over 95% efficiency? Then... there's a definite peak efficiency of an engine and it seems that running constantly at peak efficiency and using electric motors provides greater overall efficiency.

Turns out the combined cycle is about 10km of driving so I have no idea how they reach that mpg figure.

Agreed. Batteries decline in efficiency with time, especially if they're abused, do to overcharging, deep discharging, etc. If a single cell goes weak/bad can the average user replace it easily for a cheap price? You can bet your life that like all modern car manufacture it will be made as difficult as possible.

Also, what's the green cost of all the toxic materials used in the battery manufacture and disposable? Or is this all glossed over in the marketing and washed away to China or an even worse 3rd World shithole? Somalia has no functioning government, maybe we can just load it all on a container ship and dump it off their coast like everything else?

Think of it this way... in 5-8 years time you'll be able to pick these up for peanuts a cheap battery replacement using non-OEM parts and you'll be laughing.

I don't see how it affects the used car market any more than ICEs. Compared to an ICE that requires constant fettling (oil, coolant, belts, plugs) these things are easy! Replace the bits that stop working with non-OEM and you're good to go...

Not legal, you can use whomever you want, even the dealers know this. Plus, manufacturer warranty tends to be a much easier process than a side street car dealer selling the equivalent of a Dixon's policy

Given how much the batteries cost for OEM, even a cheapo after market one would likely still cost enough to write off the car. Seems the estimate of doubling the size of the BMWs standard battery would be US$11k. Probably more than the car is worth at 5 years old.

The 9L tank seems to extend the range from a claimed 90 miles to a claimed 168 miles. So 78 miles on 2 gallons, 39mpg.

It would be much better if they didn't go for the futuristic look and some how managed to replicate a 1 series and so on.


Anyway it sure is progress nonetheless.

Agree on the point that the more these sell in the future, fuels going to rocket forcing people to get electric cars Crying or Very sad

^^ Yep, Audi have managed it with the A3 which is coming out next year with a motor/ICE combo claiming something like 200MPG but looks exactly like the current A3.

Do people really want this robocop looking shite?

Not nearly as bad as ebike that have to make themselves look really stupid to justify their stupid prices.

Amused that the Audi is a bit quicker to 60.

I don't unserstand how electric car ownership is meant to happen for the masses.

My street is terraced houses, can't remember the last time I actually managed to park outside my house, how am I meant to safely and securely string a cable across the pavement to charge it?

Think holes drilled in petrol tanks are bad news? Pikeys and the like on a battery rob will make it look like nothing. Then there's the malicious cunts who'll twat a nail through it, shorting it good and proper, with the possible bonus of a battery fire.

Electric vehicles aren't for the masses. They are supposed to use the bus, tram, pedal or walk. Cars are for the select, privileged few that can afford them. That's how green communism works.

Electric cars do seem to be getting better, but as per questions above lets do a few figures.

However, I bet the big benefit is you pay around 75% tax on petrol/diesel and 5% on electricity. I would also assume power stations are more efficient at creating energy than car.

For the calc, the car says it can do between 80-100miles on a full charge. Lets say 90miles.

It also states it takes 3hours to fully charge with a 7.4kw wall box.

I currently pay 11.41pence per KWh - lets add on 10% for the coming price rise.

12.551pence x 7.4 x 3 = 278.6322pence

It would cost £2.79 to drive 90miles.

Ok, a diesel car can get 50mpg easy. So how many miles would £2.79 get you?

Diesel = 137.73pence per litre = 2.023litres of diesel (or 0.445 uk gallons)

0.445 gallons at 50mpg will get you 22.2502miles

so,
£2.79 of diesel will get you 22.25miles


But the big benefit, is I'll charge it at work! Boom!
(I don't have, or intend to have an elec car)


Edit: I forgot I was on BCF, so I'll end with ... innit bruv.

Worse than that. It is 5% tax on electricity (VAT), while with fuel it is higher (currently 57.95p a litre fuel duty, and then 20% VAT, with petrol currently £1.26.7 near work, 79.07p tax which works out at 166% tax).

All the best

If it actually 'took off', it wouldn't be unreasonable in densely populated hours to have charging posts at regular intervals with reasonably chunky chargers which would be a bit of hassle in a house - ie 10kw or whatever.

Any cost saving from electric won't last very long.

If it did happen and people stared using leccie cars the consumption would go up raising the cost (because they can, although they'll say it's due to fuel costs rising to generate it) but moreso than that, I'm surprised no ones considered that the moment people start moving to electric they'll just add the tax onto that instead of just being on fuel.

The government wants their cut from somewhere.

Who remembers diesel in the early 90s? 1/4 1/3rd of the price of petrol? The government said they wouldn't tax it anywhere near as much as petrol as it was meant to be the economical option..

Yeh.. and how much is it nowadays?

Trust me, the moment we all move to leccie powered cars that £2 odd to drive 90 miles will evaporate.

Depends where you live... Diesel is cheaper over here - €1.20/l even in my 3l bmw that makes it ~€10/100km. I think Petrol is around €1.30

Tax is a tricky one - there will have to be rather odd tariffs to allow cheap home energy and taxed vehicle energy. I'm sure they'll figure something out that ends up with us paying more overall.

As for the look - aren't people bored of the standard silver curved boxes? I mean, an A3!?! It's as generic and boring as they come. I really like the look of the i8... the i3 not so much because it's a compact SUV body. Roll on the change I say - repmobiles have had their day.

Keith - you're forgetting that battery prices are likely to reduce over the next 8 years and that a well made electric vehicle will likely hold it's value better due to the easy swapping of vital parts.

I don't really see what the kia warranty link has to do with it - someone is in the first stages of making a warranty claim and ranting before seeing it through... I bet they get it sorted for free...

Terraced houses - yup... always seen that as a problem. Street chargers? I bet they'll take the tax that way too.

ThoughtControl - as usual you've got your political ideas mixed up and seem to be ranting about nothing in particular but rather vociferously... This is green capitalism... Those with the money to spare make more money/savings... My prediction for the future is pay as you go electric driver-less cars hop in the car, use it essentially as a taxi and pay for your journey. Why would you need your own car if you don't drive it? Only the car companies will lose out... Governments will be able to tax, google will make billions, component manufacturers will continue along nicely the amount of money taken will be braodly similar, just some companies will be replaced (BMW->google etc).
