Picked up my new Advance Sport on Friday. Really happy with it although the Honda+ app doesn't seem to want to connect (cant generate pin!).
I'm slightly baffled by the regenerative braking paddles by the steering wheel. When I am in D mode if I increase the resistance to the maximum level it feels very much like B mode. It kind of makes B mode redundant really. Although perhaps I am missing something? Would be interested if anyone else who finds the paddle feature useful, maybe I'm just doing it wrong.
-
I have paddles on the E and find them useless in town traffic where every acceleration returns to light paddle and more clicks all the time so find one pedal much better. On the motorway it might be different, but I still think that once you are used to the feel of one pedal it is easy not to flutter the pedal and keep a constant speed without tiny accels and brakes, and adjust speed to conditions smoothly and efficiently. You hardly need the brakes at all except sometimes for a complete stop. I would be interested in any reliable data that paddle mode is more efficient on the motorway but have not seen it yet.
-
Personally I would like the paddles: B mode brakes too hard for my liking, D sometimes isn’t enough, so I keep shifting from D to B and back. The paddles would allow me to stay in D almost always and gently increase braking using the paddles. It would also avoid the ‘clunck’ sound when going from B to D at standstill (from the lever itself).
I think that B mode triggers maximum braking possible, and that is similar to the maximum using paddles.
-
Use the paddles going downhill to stop the car running away. Its a bit like dropping down a gear in a manual car to provide engine braking but in this case the retardation is increasing the amount of power going into the hybrid battery.
-
Sounds a complication?
-
I'd get in a flap with such complications .I wonder how many owners make full use of the facility. A bit of an affectation I think. Flappy paddles for formula 1 type gear changing makes more sense.
-
On the upside: The paddles give the same decelaration/recuperation up to B-mode only with finer adjustment plus they allow cruise control (which is impossible in B-mode)

B mode cruise control a good thing.

I realise that this is all personal choice, but I would like the 'B' mode braking to be harder.
The effect can be reduced by using the accelerator.
I have no experience of paddles, but feel they would be annoying to the say the least, using them every time you slow down ;D
-
I like B mode just as it is :)
-
I always drive in B mode, except when ACC forces me to D.
-
Surely this addition of paddles is a gimmick added to the Advance Sport, trying to look like the gear selectors replicated on the 'supercar' models. Constantly having to paddle your way to different levels of breaking... only having to reset it every time too! I find nothing wrong with the 'older' method. I drive in B around town and the occasional winding B road which are prevalent in my area, and D mode on straight and speedier roads. Easy.
-
I tried using B all the time but found with D the economy was if anything better and it means using the brakes occasionally which helps to keep the disks free of rust. I still use B for a long downhill stretch but that's all.
-
I have been a bit reckless today. Very slow German HGV in front of me. Came to lights, took the outside lane, switched off ECON, switched into D mode and floored it. The 0-30 time is seriously impressive.
Sorry - not really relevant.
-
...Why would switching to D help?

Good point! Switching the ECON off was the main thing in terms of unleashing extra power.

And don’t forget to turn off the air con, for a further 500 BHP!

I can’t perceive any difference between B and D mode or eco or not when you foot to the floor on the accelerator. Too busy concentrating on how fast the speed is building up!
Under part throttle eco and normal mode gives differences
-
It doesn't make any difference. But since none of this was relevant anyway... ;D

Switching off the air con will not unleash any more power as it is not driven by the engine. As far as I am aware it is powered from the hybrid battery, so the engine may fire up a bit more frequently to recharge the HB, and I think the ventilation fan is powered by the 12v battery.

Yes I understood eco was disabled when you floor it because it could be an emergency to get out of trouble as fast as possible.

Late to the party on this one, but I've just got an Advance Sport and discovered that the paddles can be used to modulate regen strength in B mode. Quite a useful feature I think.
I haven't tried the paddles on the open road in D mode yet, but I imagine they could be handy to regulate deceleration and avoid using the brakes too much.
-
Flappy paddles, as I have said in an earlier post, are apparently revered in the Asian market and that is where the feature is aimed, subsequently Jazz Hybrid Sport models arrive in the UK as is. So it appears they are a marketing item rather than being something very useful for the average bloke, or sheila – please note the equality/inclusivity. If you find yourself on a race track I guess that is where they will be really useful.
As for me using them on a day to day basis, I do occasionally, because there are a few hills where I live with a 20mph limit and they are useful for getting the descent rate perfect and harvest some energy to go up the other side. It just gives me more fine adjustment over the B mode selection. They don’t get in the way and are just there if I want to use them.
As for B & D it is either Black and Decker, Bondage and Discipline, or Brake and Drive. Your choice. As for driving around in B mode I gather it will do no harm but for me I maintain it is just another control (a brake is a control) for the car and I use it selectively and don’t get obsessed with the regenerative aspect.
I say that because using D mode and slowing the car it will take a certain time/distance to slow to the point you want it to. Using B mode permanently merely shortens that slowing time/distance so you have to commence slowing later to reach the same point you want to. I see no reason that the regenerative aspect will be different, and indeed will be equal in both cases.
So the choice is long and smooth deceleration or a slightly more shorter and harder slowing down. I go for the longer slow down because I see no difference as to energy harvesting, it is better for passenger comfort, and it also stops me shortening any braking too late to err on the side of safety.

It's not really as simple as that. Stop start in the city will get more braking in B than paddles, B will give higher voltage regen since friction brakes will need to be used much less. On a long mainly constant speed trips it will make no meaningful difference. I have paddles on the E with a comprehensive regen display, and hardly use the paddles at all in city driving since the relatively slow braking and constant switching does not achieve much overall efficiency at the end of the trip. And every time you touch the brakes the paddles go back to minimal braking and you start swtching all over again. Each to his own - it's personal preference at the end of the day.
-
My new elegance has no paddles. The dealer said that in D mode, using the footbrake gives regenerative braking, whereas in B mode, merely taking your foot off the accelerator does so.
-
and in D mode you do need to use the brakes more
I don't think I've ever used D
-
I don’t have paddles and I never use B mode
The only time I used B mode, over 10 years of owning a Prius, was down very steep hills
-
On the Sport model the difference between 'D' and 'B' modes is that in 'D' the regen level is temporary and the car switches it off when it decides (eg after stopping at a road junction or moving uphill). In 'B' mode the regen has to be cancelled by the driver using the right paddle, ie the regen level is remembered. The regen level is also remembered when driving in Sport mode (whether in 'D' or 'B'). There are four levels of regen available in both 'D' and 'B'.

It's not remembering the regen Levels in D/Sport mode either. What sport mode does, is automatically increasing regen to maximum when approaching v-max, and also setting regen to a medium level (2/4) by default. Essentially it's just tricking you into experiencing more acceleration, as it sneakily gives you forced recuperation whenever the car otherwise wouldn't be accelerating.
On Eco/Normal, the car will just silently stall at 185km/h with the battery kept enough, in sport mode it will actually settle closer to 170 but with a full battery charge unless you floor it.
Personally, I use B mode exclusively when driving inner city, in combination with manual speed limiter. D mode only with ACC on - as far as I'm concerned I actually find it really annoying that it doesn't associate limit/ACC mode automatically with B/D.
