I read this at numerous second-party website reviews, and then found this text in a Porsche press release:

The 2019 Macan also gains the new Traffic Jam Assist function as a component of the optional adaptive cruise control system. When so equipped, the Macan can accelerate, brake, and keep itself within a marked lane at speeds up to 40 mph.

This is very startling to me. Surely it's a mistake in writing? Adaptive cruise control works in my Panamera at very high speeds (I know over 80 mph). Does it really become disabled over 40 mph in the 2019 Macan? Does anybody know what this is all about?

The ACC will work as normal. Traffic Jam Assist is a subset of ACC using the LCA/LKA to take over during low speed traffic jams as traffic speeds up and down, just like ACC.

From Porsche (https://www.porsche.com/usa/models/p...che-innodrive/)"Traffic Jam Assist
Another feature of Porsche InnoDrive including adaptive cruise control is Traffic Jam Assist. It eases the burden on the driver when congestion is encountered on major highways. At speeds of up to approximately 37 mph, the system uses gentle steering inputs to keep the vehicle in the middle of the lane, regulates the distance from vehicles in front and follows the queue ahead where system limitations allow. To do this, Traffic Jam Assist tracks roadway signs and other vehicles on the road. The benefit? Appreciable stress relief and greater comfort on long drives."
