Hybrid batteries
Not news I know, but the Panamera is going quite a bit further on battery alone, now that the weather is warmer. My morning commute is 19 miles. A40 dual carriageway then country roads and through villages. During the winter, the engine would activate towards the end of the dual carriageway bit, then go on and off at various times through the villages until reaching the office, normally with a flat hybrid battery. I'd do around 14 miles I guess, if driving at moderate speed (60 down the A40 and no more than 70), before the engine came on.
Now though, I'm getting to the villages with the battery still on 20%. This means I roll through them without the engine running (because even though 20% is normally the point at which the engine spins up, it only does that if it thinks it's going to need to use the engine soon). So I'm doing perhaps another 3 or 4 miles just because the weather is warmer. This also means I'm arriving at the office with an engine which has just started, so there's no heat in it, but which I immediately them switch off. Porsche insist this is fine for the car but longer term I'd have thought it wasn't.
Anyhoo, interesting to me anyway

Re: Hybrid batteries
I’d love to see the Porsche mechanics face having to entertain questions like that!

Re: Hybrid batteries
YMMV but I believe my LOLvo uses the engine coolant to condition the battery pack and keep it at a constant temperature for consistent performance - so the engine is reasonably "warm" when starting after a longish battery drive anyway. Maybe something similar on the Guantanamera.

Helps sneak by the rock-throwers I guess.

Can you not choose when to switch to battery then Mark?ShockDiamonds wrote: ↑Thu Apr 19, 2018 1:05 pm Not news I know, but the Panamera is going quite a bit further on battery alone, now that the weather is warmer.

I know some other hybrids allow you to choose when to switch to battery, so when you get to town/city, you can switch your dirty IC engine off and switch to battery power. Won't somebody please think of the children?
Oui, je suis un motard.
Re: Hybrid batteries
I always try to use the petrol engine in central London to make up for the times I pay the congestion charge
How about not having a sig at all?
Re: Hybrid batteries
It’s not good for the engine, but, it would have been designed into it so probably makes no difference. It probably does more harm to the exhaust system than anything else and modern exhausts seem particularly good compared to 20 years ago.

Re: Hybrid batteries
By switching to ePower mode it only uses the battery (below 84mph IIRC) but once the battery drops below 20% the engine comes on at speed and ePower automatically disengages and you're in hybrid mode, engine and battery working depending upon road, traffic and speed. Point is by the time I get the office, which is just about at the extent of the battery's range this time of year, it's on zero and the engine is just coming on. Will probably try it in eCharge mode for a day or so next week and through the village immediately before the office in order to put some heat into the engine/exhaust before switching it off.Marv wrote: ↑Thu Apr 19, 2018 7:37 pmCan you not choose when to switch to battery then Mark?ShockDiamonds wrote: ↑Thu Apr 19, 2018 1:05 pm Not news I know, but the Panamera is going quite a bit further on battery alone, now that the weather is warmer.

Re: Hybrid batteries
Zzzzzzz
Seriously this is some dull shit. What’s the point of buying something with (faux) sporty credentials to use it like an electrical appliance?
I genuinely (as a dyed in the wool Porsche fanatic) cannot see why you’d buy some hybrid VW engined saloon over say an M5 and to hell with the MPG. If you’re obsessed with penny pinching then switch back to a 520d, no?
I just don’t get the point of them.

Re: Hybrid batteries
On the way home, engine starts immediately usually and off you go (charging as you do so). And I suppose I bought this one because of the spec, and despite the hybrid gubbins. Didn’t set out to buy a hybrid. Can see the appeal tho.
Re: Hybrid batteries
Because most driving is dull shit, and these sorts of cars are very good at that stuff. And if they hasten the death of diesels that can only be a good thing.
Anyway, with that sort of journey I'd be letting the petrol engine run as soon as I got on the dual carriageway - past 50mph the battery usage is heavy and the petrol engine fairly efficient. Plus if you need cabin heat it's better to warm some coolant to do it than use the battery to run an electric heater. If you're not charging at work, better to arrive with some battery left to use on the way home than to drain it and need to start the engine straight away on the trip home.

But the low BIK tax is very pleasing.

Re: Hybrid batteries
It’s the way forward. I tend to use the LOLvo electric motor for urban stuff and the petrol engine for motorways etc. Simple enough rationale, the motor only has 100hp, the petrol engine over 300...ShockDiamonds wrote: ↑Mon Apr 23, 2018 8:58 pmMay have a point there.
