Lotus may not use its double DRS system at the Belgian Grand Prix on Sunday after it was unable to test the update adequately during practice.
The two sessions which ran on Friday were interrupted by rain which meant that the British team could not configure the device adequately on the car due to limited running on a treacherous and wet Spa-Francorchamps circuit.
“The forecast for the next two days is for dry and warmer weather so running (on Friday) was not very useful in terms of preparing for qualifying or the race,” said technical director James Allison. “The rain also prevented us from seeing how the ‘Device’ would perform in the expected race conditions.
“With discretion being the better part of valour we will conduct P3 (on Saturday) with a conventional aero package rather than attempting to squeeze Friday’s intended evaluation into the precious final practice session,” he pointed out.
Kimi Raikkonen had previously tested the system on his car at the preceding Grand Prix and teammate Romain Grosjean was scheduled to run it Spa.
"It’s a big shame we couldn’t do much running as it was so wet,” Grosjean said. “I was really looking forward to trying the famous ‘Device’ for the first time, but I guess I’ll have to wait.”
McLaren too was expected to introduce its own version of the DDRS but the team ruled out that it would consider using the system anytime soon and would focus on other developments instead.
“The double DRS is interesting but it hasn’t received the maximum amount of resource,” McLaren team principal Martin Whitmarsh said. “We have a finite amount of resource and we try and judge where we will get the biggest bang for our buck.
“We have found other projects that deserve that resource and we have had greater performance return from them,” he added. “But we are not announcing when, where or if we are going to introduce it.”
