The challenge to get weight reductions in EVs must be continuous, although engine braking is a useful offset, no doubt

Regenerative braking (the same as on the railway actually) only works if there's a receptive element in the system. I doubt the cars have resistors to dissipate the energy as heat, so if the battery is full then you can only use the friction brakes. A good reason to not recharge every day/ 20 miles...

 

The SUV thing is disappointing. I don't want one, but as usual I'm in a minority and I just hope that there are enough people like me that someone continues to build normal cars for us.

The Chevy Bolt has a feature called 'Hilltop Reserve' where you don't quite charge fully so you have regen when you set off in the morning.

I think it's location based so it only happens at home (on your hill) but when out & about you can get a full charge.

The next MG to hit the European market, is the Marvel-R.

Based on an all-new EV only platform.

Available in tri-motor or dual motor versions.

WLTP 250 miles....(so probably around 190 to 230 in real world conditions)

Coming late 2021 or early 2022.

It is good to see that more and more new EVs are being designed from the ground up, rather than the manufacturer trying to shoehorn an electric power train into an existing ICE vehicle.

The towing eye location seems to be the same for LHD & RHD cars. Which makes sense otherwise they'd need two sorts of bumper moulding for the holes.

The towing eyes used to be on the kerbside regardless of drive side as centrally mounted is a pain and a cross/angled towing rope can be a pain when towed, so we tried to keep them to one side or t’other.

 

In the end we tried just to put them all on the one side regardless of country. partly as you say it was cheaper just to make the one component.....were you ever a bean counter? :D

Not sure about other EVs but the i3 when completely fully charged still has regenerative braking, but in fact uses friction brakes so as to keep the “one pedal” braking effect constant and transparent to the driver, in practice the amount of spare battery energy capacity needed for regenerative braking is tiny compared with the total battery capacity, so it hardly ever uses the friction brakes when seemingly fully charged.

I used to have to photograph all the competitor boards with the components wired to them in teardown, as you say every single component was weighed and analysed to see if we could do the same or better.

 

One job I had early on at Halewood was photographing part of the production process (water spray tunnel) but during the day I noticed the Escort had three extra studs on an inner wing that appeared to be doing nothing, as it turned out they were for LHD models but all models got them as a matter of course, just half inch threaded studs resistance welded in place, I put forward a suggestion (we had an employee suggestion reward scheme) to delete them from the models that didn’t need them......about three months later I got a £400 award in my pay.....that was a lot back then......just three little studs, but over hundreds of thousands of vehicles it adds up.

 

I don't know whether it's an apocryphal story or not, you may be the man to know, but didn't someone suggest painting the indicator bulbs orange instead of using coloured plastic and saved the company a fortune?

Nah, that was just a styling choice, they wanted the clear DI lenses to match the headlamp clear lens.

 

Biggest issue we had with coloured DI lenses (and brake etc) was the aftermarket versions (usually made in China) in fake OEM boxes and trademarked, after just a year the orange dye faded enough to fail the MoT, and who did the cheapskate owner come running to and complain?

The model 3 regenerates as soon as you reduce pressure on the accelerator pedal.

 

I rarely touch the brake pedal, safely stopping simply by not accelerating.

 

it’s an adjustment that I think my wife struggles with as she charges up to stop lines then brakes hard as if she was in her Tiguan.

People keep going on about SUVs but personally I wouldn't want one, too big. My current car is a Honda Jazz and it does everything I want in a car, but I can't find an EV which comes close.


Does the Honda E not appeal?

 

A bit pricier to buy, mind, so you’d need to do a reasonable mileage at much cheaper EV costs to make the economics work.

A lot pricier and much much less space along with a short range.

As it happens I replaced a 50mpg Jazz with a Leaf. It's paid for itself in fuel & servicing but the days of picking up an ex-demo Leaf for the £12k it cost me are long gone. I used to do 19k miles per year pre-lockdown.

For a Jazz replacement I'd propose a Renault Zoe. Over 200 mile range and you can get them around £22k

Looks interesting, thanks 

EDIT: https://www.driving.co.uk/car-reviews/2020-renault-zoe-review/

Still has a range issue c148miles at motorway speeds and takes ages to charge from zero-ish. A journey to the North could take forever,  they really need to double range for motorway usage, then it could be left to charge overnight like this phone!

Also c£10k more than the Jazz.

Perhaps not so interesting after all, sorry.

As does the i3 (and other EVs I beleive)......it makes driving much more fun I find, last time my i3 was in for a service/inspection (4 year/22K miles) the brakes pads were reported as “wear unmeasurable” now I’ve never seen that before on a report!

Alas I've had a sticky piston so one brake pad is low. 63k miles so far.

I once wore the brakes off a Corsa in less than 20k

This is an interesting range of developments for the bit at each corner....

Fully Charged - REE

 

Maybe coach building will make a comeback?

A motor in each wheel has been shown before, a long time ago.....I think back then it failed due to the motors just not being powerful enough in such a small package, this looks slightly different by having gearing/shaft drive to the hubs, nice and compact though.

That looked quite interesting. They mention you can change the layout of your vehicle without messing about with half shaft lengths etc.

To repair it you just unbolt the corner and fit an exchange one. Not sure on what that costs and it prevents the use of pattern parts.

 

I see it working for commercial vehicles & basic cars. If you're an expensive car maker trading on your fancy suspension & handling you can't really use this.

That review reads like they had a go in it for ten minutes and didn't really understand it. They don't say if the test car was fitted with CCS but you really shouldn't buy one without it.

I am surprised by the 148 mile figure and it does come straight off Renault's website. I'd have guessed it at more like 170. Visiting a Zoe forum might be in order.

Grabbing some CarWow quotes gets me a Jazz for £17k and a Zoe for £22k. That £5k difference will disappear if you do some miles.

I'd still go for the Zoe over the Jazz. In fact if I buy an ICE car it's going to be a Dacia of some sort. I have no interest otherwise.

I think you've missed the point.
