The Audi A2 is a Compact MPV styled five-door four- or five-seat hatchback designed supermini.
The A2 was produced at Audi's "aluminium" Neckarsulm plant in Germany. It was the first five-door vehicle on sale in Europe whose average fuel consumption is less than 3 litres per 100 kilometres (94.2 mpg; 78.4 mpg), although these figures only applied to a special "3L" version with a diesel engine, automatic gearbox, stop-start system, less power and narrower tyres. Due to the construction, the average A2 weighs less than 1,000 kilograms (2,200 lb).
The A2 has a large interior space for the exterior dimensions, including a boot, at 390 litres (13.8 cu ft) with the rear seats in place. This is significantly larger than the luggage space of the next model in Audi's range, the Audi A3. Due to the "sandwich"-type construction, similar again to that of the Renault Espace or the Mercedes A-Class, the floorpan has an upper and a lower portion. The space in the middle is used to house various components, such as the fuel tank and the engine's electronics. The rear passengers also benefit, as their foot space reaches into this sandwich space, creating a comfortable seating position even for tall rear seat passengers. This is in direct contrast to the comfort available on the rear bench of an A-Class. To improve the weight distribution of the vehicle, its battery is located inside the boot, under the floor.’
The A2 had many innovative ideas - such as the space floor storage system which was a box that slotted in the rear passenger foot well, a rear cup holder which unclipped and a double (false) floor boot where items could be hidden from thieves or the space saver spare wheel stored. The warning triangle and first aid kit have a home directly to the left of the boot opening. The toolkit was stored, depending on equipment, next to the battery; if space was needed for the navigation system and / or Bose subwoofer, it was moved to the sandwich compartment in front of the right-front seat (driver on UK cars, passenger on LHD ones). The headrests also do not need to be removed from the rear seats when they are folded, and a four-seater can have the rear seats removed in a matter of seconds. The rear seat belts also have a clip in the upper section of the c-pillar, so that when the seats are folded and returned to their normal position, the belt will not get tangled. More examples of energy saving can be found in the glovebox light that only turns on when the lights are on and the freewheel pulley on the alternator belt, meaning that the alternator is only used when necessary.
The front of the car included an unusual design feature called the "service hatch" or "service panel". On early cars, this was a glossy black panel at the lower edge of the bonnet (hood), where the radiator grille would normally be sited. Behind it are the filling points for oil and screen wash fluid, and the dipstick. Thanks to these features, in the daily use of the car the bonnet does not need to be raised.
