Mercedes will run a 2014 car during the in-season test at Silverstone for Pirelli to test 2017 tyre compounds.
Pascal Wehrlein will drive the two-year-old car on Tuesday and Wednesday after the British Grand Prix, with Pirelli carrying out tests regarding 2017 compounds on current size tyres. Wehrlein is free having driven for his current team Manor on the opening day of testing in Barcelona in May.
"It's interesting for Pirelli, for the team and even for me to get experience with the tyres for next year," Wehrlein said. "So I'm really happy to do that. It's good."
Mercedes will still be running its 2016 car during the test but is unable to use a race driver after Nico Rosberg and Wehrlein drove on the two days of testing in Spain. As a result, Lewis Hamilton will not take part in in-season testing
Pirelli confirmed to F1i that Mercedes is the only team running an extra car during the test, and the car will not be modified.
The tyre manufacturer plans to run the wider 2017 tyres for the first time in August.
