A series of Porsche 'tech spec' slides have reportedly made their way out of a dealer conference in the US this week, surfacing on enthusiast site Jalopnik.
The slides suggest that when the Macan makes its debut at November's LA Auto Show, buyers can look forward to a pair of turbocharged six-cylinder engines.
In the Macan S, that will mean a 3.0 litre unit, while the Macan Turbo will get a 3.6 litre engine - possibly the same Volkswagen-sourced engine found in the larger Cayenne SUV.
And, while the leaked slides don't mention it, we can likely expect a less powerful base model to enter the Macan range sometime after launch.
Note: The image used in the Macan slide is known to be a commissioned press rendering. Porsche has likely used this image to avoid the real Macan making its way online before the big unveiling.

The leaked slides have also revealed details of the coming 911 Targa, showcasing a single photo of the iconic model with a completely open cabin.
Interestingly, the new Targa will reportedly get an automatic roof, rather than the lift-out panels and sliding glass of earlier models.
"Fully automatic roof system to satisfy customer demands for comfort", the 911 Targa slide reads.
The 911 Targa will be based on the Carrera 4 and 4S, so expect 257kW 3.4 litre and 294kW 3.8 litre petrol engines.
Lastly, details of the new Boxster GTS and Cayman GTS models have surfaced, confirming an 11kW power bump for each model, along with manual transmissions - PDK auto an option), PASM as standard equipment, and more rapid acceleration.
On the styling front, there's Porsche Sport Design bumpers at both ends, 20-inch Carerra S wheels, an upgraded steering wheel, leather trim and GTS badging inside and out.
Watch for official news of all four models to surface in the coming weeks.
