Engine swap packaging: offset versus driveline angle

PixelDetailer78Community StarterJul 3, 20262025 Porsche Macan Electric 4SCentral Florida
2025 Porsche Macan Electric 4S, about 4,800 miles. Mocking up an engine/transmission in a chassis with very tight steering and footwell clearance. I can offset it slightly, but I don't want to create driveline vibration. What measurements should be locked down before making mounts? If I fix it I'll come back and update the thread. What am I missing?

I'd wait for the actual TSB/recall population, not the headline. Check whether your 2025 Porsche Macan VIN is actually in the affected batch before you plan a dealer day. Then you'll know the next fork. On “offset versus driveline angle,” that was the fork that mattered for me. This is from a 2025 Porsche Macan in Central Florida with 4,800 miles. Monthly payment math is how wallets disappear. I'd rather look cautious in this thread than stuck later.

New-model numbers always look better than curb weight and tire size. If this is a 2027 reveal, I wouldn't map it onto today's 2025 Porsche Macan ownership costs yet. Then you'll know the next fork. On “offset versus driveline angle,” that was the fork that mattered for me. Was this after sitting overnight? I'd rather look cautious in this thread than stuck later.

Following up on offset versus driveline angle: still happening, but I have better notes now. If the story changes I'll post the new data.

Asking because it changes the advice: If this is a 2027 reveal, I wouldn't map it onto today's 2025 Porsche Macan ownership costs yet. Then you'll know the next fork. Had a similar mess a couple years ago and that's what finally sorted it. Doing the boring step first on purpose.

Fair point. Counterpoint: If this is a 2027 reveal, I wouldn't map it onto today's 2025 Porsche Macan ownership costs yet. I'd do that before spending real money. This is from a 2025 Porsche Macan in Central Florida with 4,800 miles. If you share a photo of the worksheet, easier to sanity-check. That's coming from doing this as an owner, not a shop. I'm keeping receipts and dates in one folder.

I hear you, though I'd still want a second check. If this is a 2027 reveal, I wouldn't map it onto today's 2025 Porsche Macan ownership costs yet. That's where I'd start. On “offset versus driveline angle,” that was the fork that mattered for me. Learned this the expensive way on a previous car. Wrote this up on my lunch break.

Software recalls make me ask how much of 'driving' lives in a module now. On a 2025 Porsche Macan, I'd care more about the remedy and downtime than the press wording. Then you'll know the next fork. Write the result down so the next test isn't a repeat of the last one. Your commute and mine probably aren't the same, but the test still applies. I'll update if anything new shows up.
