Is there a sun glasses holder by the rear view mirror on the MG5?

The speed limiter bit is basically a feature of the cruise control. A feature that's probably been in all cruise controls since the early 1980s.

The cruise control has a speed limiter to keep you at the desired speed. E.G. Using cruise control while driving down a hill.

Very dodgy marketing speak in my opinion.

That's not how speed limiters work.

You set a maximum desired speed and then the car won't go above it even if you push down on the accelerator - you need to enter the kickdown step to override it (for safety)

I did a bit of an experiment in my MG5 Excite over the last couple of days.

There's a steep hill near my office.

At the top, I set the cruise control to the minimum speed, which is 20mph.

With 80% battery and KERS 3, the car held exactly 20mph all the way down the hill.

Went back the next day, straight from a full charge, and did the same thing.

With 100% battery and KERS 2 (because you can't set KERS 3 with a full battery), it did NOT hold the set speed but got up to about 30mph by the bottom.

I didn't try putting it in Neutral and freewheeling down the hill but I suspect I'd have hit a lot more than 30mph.

The inkling I got from this relatively unscientific experiment is that the cruise control WANTS to hold your set speed when going downhill, but does not apply the friction brakes in order to do so. Instead it appears to rely solely on regen - which it can't quite manage with a full battery.

Doesn't it say in the manual not to go over 5 mph in neutral ?

Probably. To be clear, I've never freewheeled a car down a hill in neutral in my life and I don't have any intention to try it. More because it's really dangerous than because it's against the owner's guide.

I don't think coasting in neutral is dangerous, especially in car that doesn't have gears.

My father used to switch the engine off going downhill when we had a VW campervan 'to save petrol'.

When we swapped the VW for a 2.8 Granada auto, he very quickly stopped doing that when he realised the brakes and steering didn't work when the engine was off!

(The same VW would also have the electronic choke disabled 'to save fuel'; once I started driving it, the first check would be to lift the rear engine cover and reconnect it - he soon got fed up of having to disconnect it again)

The danger of coasting in Neutral goes back to the old days when trucks had crap brakes and non-synchromesh gearboxes. If you coasted in Neutral and the brakes gave up it could be impossible to get back in gear. There is not a lot of difference between coasting in Neutral in an ICE vehicle and driving an EV with minimum regen or KERS selected.
With an ICE with fuel injection, there is a thing called Deceleration Fuel Cut Off or DFCO which cuts the fuel off entirely when you lift your foot off the throttle, in gear, and above a minimum speed. This is more efficient than coasting in Neutral. I use a mixture of both depending on circumstances.
All of which has nothing to do with EVs, so just an old man waffling.

 

[Kithmo]

Reading through the manual it says when loading or pushing the vehicle on to a tow truck etc. do not exceed 3 mph (not 5 mph as I originally thought).
I was thinking maybe it would damage something if you go over 3 mph in neutral ?

Aye Jocko, but with age comes wisdom.

I'm aware of modern engines having the fuel cut off when you lift off, it's very clever really and something you wouldn't think of.
More modern cars actively coast now and Kia has an "intelligent" electronically controlled clutch that automatically activates to allow coasting as that's the most efficient way to save fuel. Quite remarkable really.

the MG5 does have an overspeed warning setting hidden away in the dashboard menu, plus if you are using the satnav it can be set to warn you that you are over the speed limit. But no automatic speed limiter.

 

[ALANB]

Strange because it's in the manual... Also missing is the speed limiter, which is not mentioned in the manual but is on all the marketing material.

Also missing is the adaptive cruise control which is in the index but not the manual.
