@moritz in response to your question here, product updates are either generational changes or facelifts. Generational change involves a significant overhaul of the product such as changes in powertrain and a complete redesign of the vehicle while facelifting usually result in minor changes such as minor tweaks on the exterior and the interior. Out of the over 30 model updates in 2024, generational change will only occur on the Panamera, Macan, Tiguan, Passat, Skoda Kodiaq and Skoda Superb. The Audi Q5 is also moving to a new generation. However, it is hard to differentiate the changes made to the Q5 with that of a facelift.
In comparison to the previous upgrades, I would say Porsche 2024 product changes look significant while that of Audi are mostly minor. The magnitude of Skoda product changes in 2024 looks unchanged from that of the past. But Skoda product changes have mostly been significant. The other Passenger Cars’ 2024 upgrades such as those of the Jetta, Atlas and Golf are minor. But it’s argued that issues in the prior Golf have been rectified in the 2024 upgrade.
