Audi A1 e-tron
Audi released a summary of real world test for 120 of its plug-ins.
Notably, 80 Audi A1 e-tron prototypes and 40 production A3 Sportback e-tron), that in total covered 1.4 million kilometers (869,919.7 mi) of Electric Mobility Showcase trials in Germany.
According to the study (and as one might expect given the source), feedback from the drivers was very positive.
The fleet of 80 Audi A1 e-tron covered 87% of the total distance travelled in EV mode. In case of the Audi A3 Sportback e-tron, it was about ~70%.
The typical journey was less than 50 kilometers (31.1 miles) a day.
"In fact, 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."
As it turns out, despite Audi testing plug-in hybrids/range extended electric vehicles, drivers said they would be more satisfied with more charging points available:
"All in all, Audi concludes that the participants’ experience with clean, quiet and progressive 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. The brand with the four rings 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."
About the Electric Mobility Showcase:
"The Electric Mobility Showcase program is a joint initiative of the German government and the automotive industry. Four ministries have lent their support to 90 individual measures in four regions of Germany. Audi was one of the first vehicle manufacturers to sign up to the program and when it commenced in 2012 was involved in six projects for which it provided a fleet of 80 Audi A1 e-tron prototypes. 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 yielded valuable findings from the more than 550,000 test kilometers (341,754.2 miles) covered. 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.
In April 2015, the brand with the four rings 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."
