Macan EV appears to have single speed transmission, unlike Taycan

I know its a question that's been asked here, but I spotted this on the Macan EV configurator:

Yes. From PCA article last month:

Power is transmitted to the ground via a two-stage single-speed transmission, which uses two small gear wheels instead of one large wheel to reduce weight and footprint.

Sorry a bit off topic but anyone think that the Taycan will get a PCM update that will allow us to load non-OEM/3rd Party apps directly to the PCM screen as mentioned for the Macan?

Can't imagine a technical reason why this could not be backward compatible but def no expert there?

I'm confused.
Does a two-stage single-speed transmission of the Macan do the same as a double-clutch two-speed transmission like the Taycan?

No. The Macan is just a single speed gearbox. The two stage refers to the reduction happening through two gear sets. It’s reduced once and then a common shaft goes to another gear set to reduce again.

The Macan PCM is based on Android Automotive OS – so is very, very different to the software architecture on our current Taycan's.

However, the PCM hardware – I would imagine – is a standard enough ARM-based computer. I would be certainly surprised if it couldn't run the new OS. However, it was not designed to – so to answer the question, I think you have to ask: how motivated is Porsche to do so ?

My hunch is that it would be too much effort – however, if they could it might minimise on-going support effort.

Ah sorry missed the Android base - but your last point exactly what I was thinking but unfortunately suspect that indeed the motivation will be low!

I know its a question that's been asked here, but I spotted this on the Macan EV configurator:

I am curious as to whether Porsche keeps the 2-speed gearbox for its more premium vehicles or whether other new vehicles will get the single speed. The Macan is the lowest vehicle in the range so it makes sense to eliminate it for that reason alone but they also have a ton of learning now which may make it unnecessary.

performance on the Turbo appears better than my Taycan GTS!
So to me that sounds like the 2-speed isn’t needed anymore.

I think they move away from the 2-speed. Maybe already in the facelift. Personally I also prefer 1-speed for EV’s, much smoother.

I like the 2-speed transmission. Not ideal from a weight, cost, and complexity standpoint but it provides some personality. I am counting on Porsche to maintain some level of personality in their cars.

Yes single speed and with the 2-speed transmission also gone is the acceleration linearity. Macan 4 has almost the same 0-100 acceleration with Taycan 4 CT but its 100-200 is 13.8 sec almost 40% slower than CT! No info on gear ratio yet but macan’s single gear is very likely shorter than Taycan’s second gear and running out of stamina at high speed, just like teslas.

I thought it interesting that the Macan EV's headline charging rate is 270 kW. I thought Porsche marketing might have gone for a higher >300 kW.

The splitting of the 800V battery into two 400V ones is smart (and something that was signalled for a long time) but it limits charging to 135 kW – lower than Taycan if you have the 150 kW DC option. I was expecting that this battery splitting would have enabled charging at up to 270 kW if the 400V charger supported it.

So charging at 400V Tesla stations is capped out at 135 kW. It does mean that there is no DC booster in the Macan – and I've had my share of troubles with that component recently!

And there is no 22 kW AC charging option – even with the larger battery pack size. Is this Porsche's way of admitting that rate has been problematic ? Or is it a symptom of the shared platform (with Audi) and the new all-in-one "Integrated Power Box (IPB)" under the rear seat just hasn't gotten around to supporting it yet?

For a brand new platform the charging aspects of Macan are in some ways not the leap forward I was expecting.

Tha Taycan was a Porsche project which Audi benefited from later.
The Macan is a group development and the amount of Porsche "personality" and technology incorporated will be more restricted by others from the group wanting a standard - probably cheaper - base.
IMO

I thought they said they can use the full 150 kW without the booster. At least that was Dr Robert Meier stated? Still way below the 270 kW though. And Tesla V3 and V4 can do 250 kW at least. Wonder why the limit it at 150 kW?

Academic issue me since I will not jump on version 1 of MACAN anyway.

It looks however that they have made a number of improvements in SW etc in the MACAN.
