Happy girl! I was only allowed to sit in the back while the sales guy went through the tech in front of her. Maybe I'll get to drive in a week or so....

Congrats! It looks great George! Is that Algarve Blue Metallic?

Yep

Same as ours. It's a new Porsche color and I love it!

I was allowed to go look at the car this evening. It has Hankook tires. These used to be cheap tires. Are these any good?

Porsche puts Hankooks, Pirellis, Michelins, Dunlops, Goodyears and Continentals on various vehicles and they are need to meet their standards. I would prefer the Hankooks over the Pirellis for sure and many folks who do Endurance Racing have use the RS-4 as the Gold Standard for years , though new products are out now that are slightly better.

Definitely prefer the Hankooks over Pirellis as WillyDaP said. And agree also that Hankooks are good tires!

Another dumb hybrid question. How do you drive long, multiday, trips? What hybrid mode works best without having to find a charging station.

Not a dumb question, and good timing, as I just returned from a long weekend trip. I've also done a long trip from Wisconsin to New England and back, towing a car on a trailer on the return. In both cases I haven't bothered trying to charge it at a public station, though I did get to borrow my sister's charger at one point. I have played around with various strategies, including charging the battery while cruising at highway speeds and just using up the battery and letting the hybrid auto mode take it from there. Gas mileage drops noticeably, say around 25mpg when charging the battery at freeway speed, vs around 32mpg when driving freeway speed in hybrid auto. (And about 15mpg towing a car on a trailer ...) However, you have to account for the fact that driving on the highway in auto hybrid runs down the battery, eventually, so you're using electrons in addition to hydrocarbons. This past weekend I purposely charged the battery during the final run into my destination, where I was doing city driving (Minneapolis) for a few days. On the last day there the battery finally gave out. I kept it in hybrid auto mode the whole way home, knowing I'd charge it when I got home.

When you use the engine to charge the battery, it stops charging at 80%. At that point, it's just in the battery hold mode. You get better mileage than when charging the battery, but not as good as when you're in full auto mode. You really need to be at highway speeds to efficiently charge the battery.

"Works best" may depend on what you mean by "best". If by that you mean "optimize fuel costs", it is highly variable, depending on gas and electric charging costs. The prices I've seen at public charging spots make me more inclined to just fill it with 93 octane gas, especially in MN, where it was surprisingly low. I pay about 18c per kWh for electricity at home, and that's cheaper than 93 gas here, but not by a lot. I calculate I've saved about $500 in fuel costs after 13k miles, 4.5k of which have been electric powered.

Another good way to save the battery charge is to put it in Sport mode

Thanks. "Works best" for me is not to need to find a public charging station while on trip where I won't be home at the end of the day. I haven't tried the charge or hold modes yet. Internal combustion engines sure are less complicated to run

Grazie

We have had two! A 2021 and a 2022. Great cars! Picked the 2022 up at Zuffenhausen…. Other than the fact that Porsche REFUSED to paint it Lava Orange (so I had to wrap them both!) they’ve been great. They’ve both towed our Airstream 19’ easily.

A cold winter update from SE Wisconsin. I just posted in a different thread my experience changing the original Hankook A/S tires to Michelin winter tires. Major upgrade in all respects.

Temperatures here are hovering in the single digits (F) / -15ish (C). The e-power mode does not like these conditions. My garage isn't heated, but it's staying above freezing. As I drive away from home, the engine pretty quickly fires up, even if I'm in e-power mode. Not a huge deal, but if I'm just doing short errands I cringe at the engine doing a few cold starts. One of the things I appreciate most about the plug-in hybrid system is that I can spare the engine that stress when I'm just doodling around the neighborhood with short trips. Seems like it would be extra hard on the engine at these temps. Simple solution - put it in Sport and drive for a while to get the oil warm.

You don't want to know what energy consumption falls to at these temps.

How much does battery availability degrade at colder temps?
