Why does the Audi A2 have a rear-engine design?

I recently noticed that the Audi A2 has its engine located at the back of the car, which is quite different from other vehicles. I am curious about the reason behind this design and if it has any advantages or disadvantages overall.

The rear-engine design of the Audi A2 allows for a more spacious and versatile interior, as there is no need for a bulky engine compartment in the front. In addition, it also improves the weight distribution of the car, resulting in better handling and stability on the road.

Having the engine at the back of the car, instead of the front, also helps with reducing noise and vibration in the cabin. This can improve the overall driving experience and make long trips more comfortable.

The rear-engine design is also beneficial for safety, as it helps absorb impact in the event of a rear-end collision. However, it can also lead to some challenges for mechanics during maintenance and repairs, as accessing the engine may be more difficult.
