Formula E has confirmed the dates for collective testing at Donington Park in England ahead of its third season.
The new campaign is due to start in Hong Kong on October 9, but teams have already been extensively testing their season three powertrains for many months.
Besides the 15 days of private testing, all 10 teams are able to take part in the two collective tests at Donington Park over the summer.
The first three-day test will take place from August 23-25, with the second and third days being open to the public.
The second test is scheduled to be held from September 5-7. Details regarding access for fans will be released at a later date.
Testing at Donington will offer the Formula E paddock a first chance to check out its rivals ahead of the new season, including the new Jaguar team.
Sebastien Buemi enters the new Formula E season as the defending champion after defeating rival Lucas di Grassi at the London ePrix finale earlier this month.
