Warming up plug-in hybrids?

[Tom]

I was reading a review about a plug-in hybrid and it said something to the effect that the car will go 10-15 miles before using a drop of gas. I'm admittedly paranoid about making sure my car is fully warmed up before driving it hard, so am wondering if that means those e-hybrid cars (like the new Cayenne) won't be fully warmed up for 20 miles or so -- until after you run the batteries dead and then run it on gas for while?

No idea but I'll make myself a note to ask tomorrow when I'm at the shop.

Found your answer today from both Gold tech and sales rep - it's easy and all good. (Well mostly, anyway.)

For hybrid Cayenne's (and others as they become available), you have a choice of how you want to begin any ride - gas or electric.

However, the catch is that electric is the mandated default. (You know where the mandates come from ...).

Much like auto start/stop, the default is for electric-only when one "starts" the car and drives off. So, choose ICE instead and that's how you'll be powered. Of course, the ICE option has to be selected manually via PCM every time the vehicle is turned on.

That is until intrepid souls figure out how to program a permanent start mode override.

Great info, thank you. Any idea if there are programmable diamond buttons on the steering wheel to pull up ICE mode? Or a mode dial that you can turn to some sport-ice-only mode?

I don't know. Either (or both) of those options would seem logical based on current setups we have in the newer Porsches, but logic sometimes flies out the window. PCM settings were mentioned today so i didn't pursue it further. I don't think there are any hybrids at the shop but I'll be there again tomorrow and will look.

On another note, was trying to figure out if I could jury-rig your license plate mounts for the new Cayenne that is due in mid-Feb, so I looked at the rear plate area of one today and I don't see a way to make anything work. I guess it's drill time - the different dimples for various countries' different sized plates are there, so in that respect it's a "world" car I guess. Unfortunately, the surface as dimpled and oddly shaped - not much to stick to.

The Cayenne I looked at today has already been drilled and has screws in it. The material is thicker than that of 718's and 911's but it's still some kind of plastic material.

Some of the early base 992's had an unpainted, textured plastic like that for the license plates. My local dealer actually used our 992 mounts on that material, but I was never all that comfortable they'd stick with the same tenacity as they do on smooth paint. We could surely design a shape that could fit that area with 3M molding tape, but I'm interested in those two screws in the middle? If those are secured in metal, perhaps we could design a piece that secures to the bumper with those screws, and extends out where needed to offer threaded holes for the license plate?

I thought you might ask about those screws!

My first thought yesterday was that they held were there to hold the raised portion but there are no seams around the edge - the raised area is molded with the rest of what's visible in the picture; they are one and the same. I have not figured out exactly what they are for. Maybe they are helping to secure the bigger piece?

I'll look into it further when I'm there today and take better pics. I'll get some measurements too.

We've been driving a 2016 Audi plug-in as our primary car for 7 years, and I'd be really surprised if the Porsches behaved any differently.

In our Audi, when we drive until the EV battery reaches the depletion point (~7kWH of the total 8kWH capacity), the ICE powers up. But it does not begin driving the car immediately. Instead, the car continues on electric while the ICE runs at a steady 1700 RPM while disconnected from the transmission until it reaches what Audi considers to be safe operating temp. Generally several minutes. Only then does it take over from the electric motor.

Hmmm... is it off-putting to drive around with the engine rev'ing itself like that? Does the heater work on electric power when on electric power, and switch to the heater core when the ICE takes over? Overall, does it feel like clunky transition technology or pretty sorted?

Not really. After a time or two you don't really notice it.

Does the heater work on electric power when on electric power, and switch to the heater core when the ICE takes over?

Yes to both.

Overall, does it feel like clunky transition technology or pretty sorted?

Actually quite nicely sorted. Especially given that we are talking about software written 8 or more years ago.
