Why is there a hump in the rear seat of Volkswagen cars?

[NevaehDella]

The reason for the hump in the rear seat of Volkswagen cars is: to maintain the flatness of the chassis. Since the car chassis is equipped with an exhaust pipe or drive shaft, rear-wheel-drive vehicles typically need to transmit the engine's power to the rear wheels through the drive shaft, which structurally requires such a hump. Taking the Volkswagen Lavida 2021 model as an example, its body dimensions are: length 4670mm, width 1806mm, height 1474mm, with a wheelbase of 2688mm. The Volkswagen Lavida 2021 is equipped with a 1.4T turbocharged engine, delivering a maximum power of 110kW and a maximum torque of 250Nm, paired with a 7-speed dual-clutch transmission. It adopts a front suspension type of MacPherson independent suspension and a rear suspension type of torsion beam non-independent suspension.
