2011 Spanish Grand Prix
McLaren engineering director Tim Goss says the FIA’s plan to restrict the use of exhaust gases to increase downforce would affect most teams.
Speaking during a Vodafone McLaren Mercedes phone-in Goss said: “I think all the major teams are up to the same tricks with regards to engine mapping. Certainly we exploit them.
“The latest guidelines on use of engine to drive floor systems, if that came in it would be a performance setback to us and I know it would almost certainly be a performance setback to our main competitors.
“As to whether it affects us more than our competitors it’s impossible for me to say. I know what we get out of it and we get quite a substantial benefit. But I imagine it would be just as sizeable a setback to our competitors as well.”
He admitted the FIA’s plan had not been discussed by the Technical Working Group: “It’s been around for a while but there hasn’t been much debate about clamping down on it, if any.”
Goss added the FIA were keen to restrict how teams use their exhausts in this fashion: “For the moment it would appear the FIA have decided it’s quite a complex matter and they need more time to consider how they will try and police it.
“As a result it looks like at the Spanish Grand Prix it will be business as usual.”
Goss explained why the team abandoned their planned upgrade at Istanbul:
“Just prior to the Turkish Grand Prix we had a relatively minor issue which meant that I wasn’t confident the upgrade would be durable for the race distance. So we pulled out of that at the last minute.
“We’ll re-evaluate all of our upgrades on Friday in Spain and those that look good we’ll take forwards.”
He said the team planned further changes this weekend:
“As you know we introduced a change of concept at the rear end of the car just before the start of the season.
“We’ve been living with some sub-optimal packaging in that region for several races now and I think what you’ll see is some bodywork and floor changes that aim to tidy up that area of the installation.”
