Regenerative braking vrs normal braking??

Driving the thing in the mountains suggests to me that it is more akin to second gear.

That's exactly the point - when I refer to engine braking, that includes going down the gears as well.

Yes, but dropping to second gear on the flat from 40mph would imply a significant deceleration!

With the brake lights not lighting...

But I will have gone through 4th & 3rd first!

On a manual gearbox, yes - but there is no gearbox in a PHEV - just the regen brakes. You will do whatever the Mitsubishi programmers have defined - which, according to some (my PHEV arrives next week, so I'll be able to test), is rather harsh braking to not have the brake lights come on.

Hi,
To be fair I wouldn't call B5 regen braking harsh, probably more like moderate braking, or as been described like changing down through a manual gearbox to induce maximum engine braking.
Kind regards,

the thing i would point out is that on the UK roads I've been driving with my PHEV, its mainly at commuter time when many others are in a rush, distracted, or just plain daft. When i used B3 / B4 / B5 to slow down before a line of stationery traffic or a red traffic light, the driver(s) behind often dont look beyond my car at the impending stop, but rely on my brake lights to indicate when they should slow down.

I even heard the ABS of the driver behind kick in once he was having to stamp on the brakes so hard to avoid me. I'd been on B4 for about 10 seconds reducing from 40mph to 5mph down a slight hill with a line of creeping traffic ahead.

Being right won't make it any easier when the idiot slams into the back of you, so for the sake of less than one extra mile per EV charge, when there is traffic behind me (within about 75/ 100 metres as a guide) I don't go beyond B2 without it being a deliberate act and watching the car behind. I agree they should look out. I agree its the same principal as engine braking, not disagreeing at all. I just want to get home without having a muppet slam into the back of me and even worse finding them uninsured.

That was what I was trying to say in my reply on page 1 to help the newbie from my experience. The beauty of this forum is everyone can share their experience but I'm not hearing anyone with a PHEV say they put the car into B5 with traffic behind them and never have a problem

I do not think Mitsubishi intended the B settings for daily use, rather for mountain driving.
It makes next to no difference to normal braking, so why go to the trouble

I agree, why use B5 to slow the car down when using the foot brake does the same thing(even generates more than B5 at speed).

Really? Using the footbrake charges the battery better than B5?

 

[Fragge]

Yup, take a look at the Power/Charge meter when you brake using the foot pedal and using B5 and compare the two. B5 only manages to Charge about 80% on the meter and the foot brake can charge 100% when braking from higher speeds.

+1
Definitely

Hi,
I agree, don't use B mode except to control speed when descending. We seem to be having a concensus
Kind regards,

But how else can I pretend I'm in a sports car if I don't paddle? And won't the brake pads need replacing sooner :lol:

Don't use the ECO button?

It will still use regenerative braking provided you don't leave it too late - the trick to getting good fuel economy out of any hybrid is "brake early and brake gently" - what they used to teach, but nobody seems to do any more!

No, the brake pads will wear the same, as the brake pedal does exactly the same regenerative braking as the paddle does (actually a bit more effectively), only when you reach the limit of regenerative braking the disk brakes will come in additionally.

You're taking half the fun out of driving it, though :shock: . I'm going to paddle regardless

The brake pads don't engage on the paddle, do they? I thought that was one of the disadvantages of relying on the paddle - if the traction battery charges to the point where it cannot accept the output of the generator, the paddle ceases to have any effect?
