The vehicles were equipped with data acquisition equipment. The objective was to determine what expectations the trial participants had of electric mobility and to what extent these were met in everyday use.

The first phase of the project with the Audi A1 e-tron lasted one year and covered more than 550,000 test kilometers (341,754.2 miles). Specific issues were investigated in the individual locations of Berlin, Nuremberg, Munich, Stuttgart, Ingolstadt and Garmisch-Partenkirchen. These included a new system for the charging and communications infrastructure and how electric mobility can be coordinated with the supply of green electricity to homes.

With the Audi A1 e-tron, a prototype electric car with range extender, users quickly learned to trust in the technology, with the result that they were able to make extensive use of the car’s all-electric range. By the end of the trial, 87% of the distances traveled by the participants were being covered using electric power alone.

In April 2015, Audi stepped up its involvement in the Electric Mobility Showcase, with 40 production models of the Audi A3 Sportback e-tron taking to the road in Berlin, Munich and Stuttgart. As of March 2016, they have covered around 805,000 kilometers (500,203.8 miles) in total, gathering findings on issues such as the charging infrastructure on public roads and the usage patterns of commuters and commercial delivery services.

In this second phase of the Electric Mobility Showcase program, the trial participants in the 40 Audi A3 Sportback e-tron cars used all-electric mode for 70% of the distances traveled. Though the compact models with their plug-in hybrid technology are also well suited to long journeys, the test drivers usually covered less than 50 kilometers (31.1 miles) a day. As a result, they stayed within the vehicles’ electric range.

Around half of all routine trial trips made by the users were shorter than 10 kilometers (6.2 miles). One participant, who had a particularly fuel-efficient driving style, refueled only once during a five-month period, despite covering 7,700 kilometers (4,784.6 miles) in his Audi trial car.

Audi concluded that the participants’ experience with electric mobility was a very positive one. However, the degree of satisfaction depended greatly on how conveniently they had been able to charge their vehicles.

Most users want to see a widespread infrastructure and generally greater promotion of electric mobility by the political bodies. Audi is pushing for the charging infrastructure to be expanded into customers’ garages as well as workplace car parks. Audi is also working with partners to develop a Europe-wide network of public rapid-charging stations which use direct current.

At the same time, Audi is also expanding its range of e-tron models.

By 2018, we will have five plug-in hybrid models in the range and will have launched an all-electric SUV with a range of more than 500 kilometers (310.7 miles).
