4S rear drive unit is attached directly to the body (like the Turbo)

[LivingTheDream]

When the 4 and Turbo were introduced, it was noted that the rear motor was mounted differently for the two models. For the 4, the drive unit is mounted within the chassis subframe. For the Turbo, the drive unit is rotated around the vehicle’s transverse axis (positioning it as far to the rear as possible) and attached directly to the body via four mounting points.

While reading a review of the newest Macans in Autocar, I noted the reference to a "rigid-mounted drive motor" for the 4S. Curious, I did some digging and sure enough, the rear motor for the 4S is, like the Turbo, mounted directly to the body (see this article in the Porsche Newsroom). Not sure if it's also rotated to the rear as in the Turbo (the Newsroom article is a bit vague on this), but the 4S does get the same mounting point.

I've not seen this reported anywhere else, so I thought the forum would like to know.

It actually is quite clear on this point: “At the rear axle, Porsche developed the ‘Performance’ styling for the Macan. The electric motor has been rotated around the vehicle’s transverse axis and positioned as far to the rear as possible.”

Thanks for sharing.

When I first read the text you quote, it struck me as ambiguous. It talks about the rear mounted motor and its contribution to a rear weight bias, but then references the weight distribution on the RWD Macan—which does NOT have a rear mounted motor. That model owes its rear weight bias to the fact that it does not have a front motor.

Reading further down the same article, you can deduce that the 4S has the same rear mount as the Turbo (even though it's not stated explicitly). The giveaway is this sentence: “The separate connection between the axle and the electric motor creates space for rear-axle steering and for the PTV Plus rear differential lock.” Although you can option the RWS in all models, the PTV can only be specced on the 4S and Turbo. So, a nice little tidbit to further differentiate the 4S from the 4.

Based on the referenced article (and other Porsche citations), we can infer the following weight distributions (front/rear) across the model lineup...

• Macan RWD: 46/54 (due to lack of front motor)
• Macan 4: 50/50
• Macan 4S: 48/52 (this could be less due to lighter motor than Turbo)
• Macan Turbo: 48/52

I'd be happy to correct this if anybody can find a hard citation on the weight distribution for the 4S (the only one for which I don't cite Porsche's numbers). Options (e.g., RWS) may also impact these numbers a bit.
