Audi A2 is an unremarkable hatchback. It is a small car with advanced design level specially designed for 2 1 century: all-aluminum space frame body ASF. The so-called ASF concept is that the dashboard is supported by high-strength aluminum alloy structure, and the space frame is composed of extruded profiles of vacuum die-casting joints, which are combined into a light aluminum alloy body. From the front pillar to the edge of the luggage compartment, including the door handle pit, aluminum is stamped and formed. The front pillar (A-pillar) adopts a new technology of high-pressure aluminum casting. Because Audi A2 adopts ASF spatial structure, its body weight is lighter than traditional steel body by more than 40%, and the whole vehicle weight is less than 900 kg. The aerodynamic performance is good, and the air drag coefficient is only 0.28; The "space floor concept" design less than 4 meters long makes the rear passengers feel spacious and comfortable; The compartment space is changeable, and the rear seats can be folded and disassembled to make room for placing articles; Set up a "service module" to facilitate the owner to maintain the vehicle; Vehicle pollution is low, and the emission conforms to Euro 4 standard.

Audi A2 has two engines, one is a gasoline engine and the other is a three-cylinder TDI direct injection diesel engine. The displacement of both engines is 1.4 liter, and the maximum output power is 55 kW. The maximum output torque of gasoline vehicles 126 Newton meters, and the maximum output torque of diesel vehicles 195 Newton meters. The above two engines are matched with a 5-speed manual transmission.
