So I can confirm that Range mode is front motor (still) and when on the level and brakes are applied drive then swings to the rear (40mph).
My point came from an article I read about the new range mode for 2022 cars which seems to be better.
Braking is regenerative so ideally the back torque will be distributed appropriately by the brake-by-wire system to keep the brake balance ideal front and rear.
I think though that all cars got the latest software updates WMA5/6/7+ impacting / tweaking range etc.
I am not sure of anything but plenty of mentions it has gone and no reports that it is due to a glitch.
Late July early August for October delivery but given the Ukraine situation that could be up in the airI am not sure of anything but plenty of mentions it has gone and no reports that it is due to a glitch.
I am disappointed because I found that particular display the most interesting of them all
When are they due to build 2023 models? Maybe it will come back.
Wow. Exactly what I was looking for. Very useful. What about Sport Plus then ?from https://jalopnik.com/an-extremely-detailed-look-at-the-porsche-taycans-engin-1837802533
Shifting That Two-Speed Transmission
What’s most interesting about all of this is how Porsche sets up the shifts in the rear two-speed transmission. To demonstrate the advantage of the two speed, Porsche showed curves of wheel torque (which is directly related to vehicle acceleration) versus vehicle speed for each motor/gear ratio combination—see below. (These look like typical EV torque curves).
As shown, at about 100 km/h, or 62 mph, first gear runs out of steam, and the motor isn’t able to send much torque to the rear wheels (and at 81 mph, the motor hits its 16,000 RPM max speed), which hurts vehicle acceleration.
It’s at the point around 62 mph vehicle speed that the Taycan upshifts, yielding the solid green curve you see below, allowing for more torque at the wheels, and thus more acceleration to a higher top speed.
The shift strategy changes based on the drive mode, which hold gears differently. Range and Normal mode, Porsche told us, prioritize second gear to optimize efficiency. It is worth noting that, in some cases, the Taycan can actually run completely in front-wheel drive and decouple the rear transmission to reduce losses.
Though Porsche considered it, the front transmission has no clutch to allow for decoupling, so the motor is always mechanically connected to the wheels. This, if I understood it correctly, was done for packaging and reasons related to vehicle control, and with the understanding that the small motor and planetary gearbox don’t yield too high losses.
Back to the modes: Porsche says “Range” only goes into first for reversing functions (this is due to mechanical constraints, as I understand it) and “Normal” downshifts during heavy pedal inputs. “Sport” mode, on the other hand, holds first gear as long as possible to maximize acceleration. Porsche even provided some shift maps below:
The map here doesn’t look that different from that of a traditional transmission, with the blue and purple lines representing when the vehicle would upshift or downshift, respectively. If I’m reading this right, looking at the “Range” plot, you can see that at only low vehicle speeds and extremely high torque requests (in other words, the driver is deep on the throttle while traveling slowly), you’ll cross the purple line and downshift to first.
Then, even if you keep your pedal buried, the car will shift to second around 75 km/h. Otherwise, in “range” mode, you’ll be in second always. (In the slide above, Porsche says “Range” stays exclusively in second gear, so perhaps I’m misreading the shift map. (Update: Porsche confirmed that even “Range” mode will downshift to first).
The “Sport” map shows that even at low vehicle speeds and low torque requests (your foot is barely on the pedal), you’re in first gear, and you won’t upshift until you hit roughly 75 km/h. This shifting, in case you’re wondering, happens roughly as quickly as a dual-clutch transmission shift.
“We are not faster [than a dual clutch],” Richter said, “because we have a large ratio spread between first and second gear,” and therefore transmission needs time to synchronize. Still, the good news is that, according to him, there’s “no traction interruption during shifting.”
No shit Sherlock!
Great information Whitex thanks. Any description of what the Operational level refer to specifically? I can see that the trigger temp raises with the Op Level but is there any other actions at each level? (I assume flap opens and pump/circulation starts, is there a variable flow pump on the circuit or just thermostat control?)One other difference which may not be obvious. I mentioned this in the quick summary post earlier in this thread that the high voltage management changes based on driving mode, but perhaps it's worth elaborating on. Driving mode will affect your range (to a different degree depending on how you drive it and outside temperature + wind) because the battery is kept warmer in cold weather and cooler in hot weather. Here is what the numbers looked like for 2020 Taycans, they may have been tweaked since of course (since it software defined).
So for example, if you drive the car the same calm way in Range vs. Sport+ in 34F weather, in Sport+ the battery heater will be using energy while in Range mode it will not. Of course if you are driving the car hard and the internal battery resistance keeps the battery warm between 70F-89F without any heating, then there will be no range difference between Range and Sport+.
AFAIK operational level refers to the heating or cooling capacity rather than the temperature thresholds (the operational levels switch based on temperature thresholds as shown in the graphs). Higher operational mode can move more heat, by increasing the rate of flow of coolant, fan speeds, opening/closing vents, reconfiguring the components through which the coolant flows (bunch of multi-way valves allow creating different independent coolant loops between various component, pumps, heat exchangers, heaters, chillers, or radiators, rerouting the flows as needed). There may be other variables adjusted as well - welcome to software defined cars.
