Lotus have confirmed that Kimi Raikkonen will take part in the Young Driver Test alongside Nicolas Prost and Davide Valsecchi, but Romain Grosjean will be absent.
Several teams are making full use of the FIA's decision to tweak regulations to allow race drivers to sample the new Pirelli tires at the three-day test at Silverstone from July 17-19.
Lotus are no different and they will use Raikkonen on the Friday while development driver Nicolas Prost will be in action on Wednesday and their third Davide Valsecchi will be behind the wheel of the E21 on Thursday.
"It's great timing for us to have this season's Young Driver Test scheduled in the middle of the year as it allows us to evaluate more of the new parts we have for the E21 as the championship battle intensifies. Remarkably, the UK has been having some notably good weather recently so we're looking forward to getting some good running across the three days," said team boss Eric Boullier.
"By running Nicolas and Davide we are giving them both invaluable experience and also gaining great feedback, as we've previously seen what they can do in the car and appreciate the valuable information they give us. It's also a fabulous second opportunity for all Formula 1 fans to come and see the teams in action at Silverstone."
