GTS Range Over 4S

[badboy1980]

Dear all,

I note that the GTS shows more range now on the WTLP rating. Does anyone know why and does it genuinely have more range than the 4S? Thanks in advance.

I went today to my Porsche dealership. Still haven’t placed order for my Taycan… so I’ve talked to the lady in sales and she clearly didn’t know either why there is so much difference in range. She was trying to convince me that GTS has better wind resistance ? I’ve asked her directly that maybe there were some software updates and optimization for battery usage but she denied.
She also told me that I need an onboard 22kwh charger to use 22kwh charging at home but it also doesn’t make sense to me. Any one can confirm this?

Its a new model so the recently assessed WLTP figures are up to date & representing the latest tech that all the other models already have (since the 2022 update).

But the existing models have not yet been re-assessed so their stats are showing the previous performance before they were upgraded.

So in fact the GTS and 4S (both having the same battery) will have very similar range - just not yet showing in the published stats

hope this helps

Ahhh... that makes sense. I just checked out the Porsche website and it still seems that the 4S has marginally better range with Performance Battery.

I did have a 4S on order, which was due March. I have been told that the GTS will come around June. I think I am going to wait till June for the GTS instead.

What electrical supply do you have at home - single phase or 3 phase?

If single then the max kW you will get is 7.4kW.

If you have 3 phase then you can get up to 19.6kW (22kW).

Standard onboard AC charger in the car is 11kW.

To get either of 11kW or 22kW you will need 3 phase supply.

To get 22kW or 11kW charging (assuming 3 phase supply at home) then you need the 22kW AC onboard option or stick with the std 11kW and you need an EVSE which can handle it e.g Porsche Mobile Charger Connect (PMCC) or equivalent.

Single phase is perfect for home overnight charging.

Nearly all public charging you will do will be DC (much faster) rather than AC.

The wall box or EVSE (Electrical Supply Equipment) is not a charger. The charger is in the car.

Thanks for the explanation. I have 3 phase power supply and afaik I have 32A 400V power outlet in my garage. I thought that I can connect external 22kwh charger which I could put in my garage. So looks like I was wrong.
One thing I have to change is my and my provider fuses, on paper I have 9kwh supply... could be a problem I think ?

I have 3 fase 230V here in Belgium but not 3 fase 400V. For 22 kw charging you need 400v.

You need the optional onboard 22 kw charger. Otherwise it will just charge at 11 kw even if you plug it in on your 22 kw wall box.

so in order to be able to charge at 22 kw at home you need a 22 kw wall box, 3 fase 400V in your house and the optional 1800 euro onboard charger

For clarity you cannot connect any external charger to the car - the charger is physically built into the car

The electrical vehicle supply equipment (EVSE) - private or public - which you connect to the car simply provides the electricity and nothing else. People refer to these as chargers but they are not - wall box or charge point would be more accurate.

So if funds permit add the 22kW AC option given your perfect home setup.

There are some places in Belgium where you can have 3x400 V. For the 3x230, you can buy an autotransformer. It's expensive but it will transform the 230 to 400V.

I live in Brussels where it's monophasic 230V (optional 3x230V). It charges with 7.4 kW which is enough for me. Otherwise I need to redo all the electicity in the house.

sqr(3)x400Vx32A = 22,17 kW.

I can have 3 x 400 v but I don’t want to. I will need extra installation and extra tax soon.

I just read that the GTS has more efficient motors which consequently provide more range. Apparently the motors have "less friction" now and these motors will also be introduced to other models too.

No, that's a software optimization which makes able to unplug physically the rear motor in range mode. If you take the Porsche range calculator, you will see that the GTS has less range than 4s.

I am pretty certain the motors are better. Also see the wltp range. The 4S is stated as 26.0-21.0 kWh/100km whilst the GTS is 23.3-20.3 kWh/100km which is lower i.e. better efficiency.

"Technological enhancements: more range in practice
The new Taycan model year will not be homologated separately, so there will not be any new WLTP range values. However, the real-world range of the latest versions will be greater in day-to-day use. Extensive technological developments have been implemented to achieve this increase. In Normal and Range modes, the front electric motor is almost completely decoupled and de-energised in the partial load range in the all-wheel drive models. Furthermore, no drive is transmitted to either axle when the car is coasting or at a standstill. This electric freewheel function reduces drag losses. The motors are switched on again within milliseconds only when the driver requests more power or changes the driving mode."

They did the same optimization on the e-tron and they retrofit on older model via an update.
