part of the () UK-wide program involving trials of 340 ultra-low carbon vehicles from several car makers. The selected test area is roughly a triangle contained within the M40 motorway between the M25 motorway and Oxford, the A34 south to the M3 motorway, and the M3 back to the M25. The 40 Mini E electric cars were kept in use after the trial was completed in March 2011, participating in activities to promote awareness and understanding of electric vehicles. These cars were part of the BMW Group UK's official vehicle fleet of 4,000 low-emission luxury vehicles deployed for the London 2012 Olympic Games. The fleet also included 160 BMW ActiveE electric cars. China Field testing in Beijing started on 22 February 2011. Testing also took place in Shenzhen. Japan A field trial took place in Tokyo in 2011. Field test results The main concerns reported by those participating in the U.S. during the first year trial were range anxiety and lack of public charging infrastructure, as the country had only 734 public charging stations, most located in California. Another concern was the range on a fully charged battery reducing to between 80 and during very cold weather. In the UK, an abnormally harsh winter also showed how very low temperatures diminished power output until the battery 'warmed-up'. There was one report of the range dropping below in sub-zero weather. There were issues reported with exterior charging points as winter temperatures dropped dramatically. Other complaints in the U.S. related to the lack of space in the car as the battery pack eliminated the Mini's back seat and most of its cargo area, and the difficulties found in practice to install the charging equipment in homes; installation permits, site visits, inspections and installation could take up to a month. BMW According to the BMW team of engineers responsible for the demonstration program, the following facts and key lessons were learned during the Mini E first year trial: Most of the Mini E applicants were well-educated and well-off males over 35, with an affinity for new technology, willing to experience a new and clean technology, and for them the lower vehicle running costs were not very important. Most drivers used the Mini E as a second vehicle and for the daily commute. Longest trip in a Mini E to date was In the Berlin trial, the average Mini E remained stationary for over
