The A2 is built using significant aluminum metal message, providing important weight reward over same sized cars. This helps the automobile to be importantly more efficient than vehicles using conventional form; under positive lot, use of only over 2 50/100 kilometer (128 mpg, royal gallon) is potential.

The Audi A2 won the Nordic Countries EcoRun efficient drive wash in 2005 with use of 2.62 liter/100 kilometer. Even the natural petrol engined versions are able of 5 50/100 kilometer. The A2 uses a place build plan: the out panels of the system have no functional use similarities live with the new Renault Espace and the "place build" bears the forces making on the auto.

Due to the option to make "knots" rather of welding the place build improvements in case stability, case strength, lower weighting and best home place are obvious. Unfortunately, the price of making with aluminum, especially with little product runs, meant that it is expensive

This may have contributed to the comparatively boring sales in connective with the paucity of selling from Audi. Audi was the best maker to hear and contain lightweight construction concepts using Aluminum and linked alloys into an "aggregate marketplace" vehicle; the old efforts at using a Space Frame were determined to the quite more valuable A8.

As per the people comment the full case weighs then small that two folk can well take it upward; the face board over the doors including the An and D-Pillars weighs some 2 kilo The A2 can, still, so be took a trailblazer for different newer aluminum-based vehicles, much as the here A8, future Nuvolari and TT and the here Jaguar XJ and XK8 serial.
