Which Volkswagen models do not have a rear floor hump?

[SimonFitz]

All Volkswagen vehicles have a rear floor hump, which is designed to accommodate the exhaust pipe and drive shaft. The chassis of sedans is relatively low, and without this hump to house the exhaust pipe, scraping could occur on certain road surfaces where the exhaust pipe is positioned too low. Many four-wheel-drive and rear-wheel-drive vehicles also feature a rear hump, which not only accommodates the exhaust pipe but also the drive shaft, making the hump more pronounced in these models. The Volkswagen Group encompasses eight brands: Volkswagen Commercial Vehicles, Volkswagen Passenger Cars, ŠKODA, Bentley, Bugatti, Porsche, Scania, and MAN.
