BMW Sauber is planning to runs an improved KERS system at the Turkish Grand Prix next month, team boss Mario Theissen has said.
Theissen claimed the new KERS will have a better packaging that the team hopes will allow drivers to achieve a better balance in their cars.
The new package was designed in conjunction with the aero upgrades introduced at the Spanish Grand Prix last weekend, but the team decided not to run it in order to be able to focus entirely on the aerodynamic improvements.
"We have developed the aero package and in parallel we are developing a new KERS package which fits the new aero package," said Theissen. "These were on the same schedule but we have decided not to combine it because it was clear to us that the new aero package alone would eat up all the time we have on Friday and Saturday morning to get it sorted, or almost sorted.
"And if we then had a new KERS at the same time, it would have been too much. We are planning to have it in Istanbul."
The team will not be running KERS at the Monaco Grand Prix, where Theissen says it would not have any benefits.
"It was clear from the beginning of the season that it would not give us the benefit in Monaco," he said.
