Have'nt they learned from Toyotas misguided placement of the electric motor?

Sending the power through a gearbox sabotages the whole power transfer.

@ Macroshaft -

I beg to differ. Cost and weight of an electric motor are primarily defined by rated torque, which is proportional to rated current. Directly connecting an electric motor to the wheels translates to a heavier, more expensive solution.

Combining ICE and electric motor torque upstream of the gear box means the electric motor can be kept small and always operate in an efficient speed range. Permanent magnet synchronous motors cannot be field weakened without additional features.

I agree with Macroshaft, they should’ve simply designed an electric motor with the needed rpm; any extra weight as a result would’ve been offset by losing the transmission and related components. It might have been more expensive but we’re talking about a Porsche here, furthermore doing it in parallel as they did reduces efficiency and reliability.

My guess is they have a lot of old mechanical engineers sitting around and didn’t want to leave them jobless.

Not wishing to detact from the efforts and merit of this concept, especially the slim profile in line electric motor as shown.
Definately the logical place for the (apparently twin ) electric motors is on the drive wheel axis.
Eliminate the bevel drive for a huge 15% plus straight up efficiency. Use a twin - centre mounted drive motors, with a diff lock in case one blows, to provide intergrated regen braking and traction control , lighterweight control units via reduced killowatt capacity each.
This could work with either a seperate FWD for the ice or a full electric drive from say fuel cell or turbine, constant speed deisel or other electric. Or just plain old plug in electric.
For those city types that need a Porshe with the sunroof down to look cool in a traffic jam twice a year when the the mood takes .
Could even come with a Porshe tm carport complete with solar charger.
As long as it still looks like a Porshe, Then I'd have to consider the possibilities myself.
Come on Porshe , blow us away.

RAF, you are a class act. Some responses are, say, less than well thought out, at best. Keep posting, man. (By the way, Porsche is not know for shabby engineering)

Building an electric or hybrid electric vehicle wherein the electric motors act directly without benefit of gearing is a "less than optimal" idea. Way less.

@ Rafael, I agree with Bud that your comments always display a high level of class and knowledge. However, the PM motors can be field weakened and really must be in order to operate at the speeds needed to get the necessary power in the allotted package space, particularly when very high low speed torque is also needed, driving up the magnet strength. The burried, embedded, or interior PM motors are field weakened quite easily, in fact, not very differently than d-q control (or alpha-beta in Europe perhaps) for induction motors.

@roy, so tesla? are resorting to a twospeed trans. So put a planetary -through on the center mount coax motor and a smile on your dial.

I think that in the case of Tesla, it was the realization that they needed two speeds later on in the game. It sounded like the investors were not happy that this was not thought through early in the process. It is speculation on my part, but they did have a recent major change of personnel at Tesla.
