The so-called cardan tunnel , an elevation between the seats in the interior of a car, primarily houses the cardan shaft from the front engine to the rear axle. However, many vehicles without a cardan shaft also have such a tunnel , equipped either with pure front-wheel drive or pure rear-wheel drive, such as the VW Beetle . The tunnel then serves to stiffen the body and can contain the exhaust system, shift linkage, lines for cooling, brakes, fuel, etc.

In some electric cars, the space is used to accommodate battery modules.

The original Mercedes A-Class Mercedes-Benz series 168 had a flat interior without a cardan tunnel, or even the full area of ​​the interior due to the sandwich construction with double floor .
