Engine stockpiling clampdown
The changes to prevent stockpiling of engine components was proposed after Mercedes decided to amass a 65-place grid penalty at the Belgian Grand Prix. As a cost saving measure, when a driver uses more than their allocation of engine components for the season they are hit with grid penalties, but the spirit of the regulation is open to abuse. In the knowledge that Lewis Hamilton could start no lower than 22nd on the grid in Belgium, Mercedes fitted three new power units to his car over the weekend in order to concentrate all his penalties on one race while ensuring he had fresh engines for the rest of the season.
In reaction to the component stockpiling in Spa, the FIA has made the following change to the regulations: "During any single event, if a driver introduces more than one of a power unit element that is subject to penalty, only the last element fitted may be used at subsequent events without further penalty. This is to prevent the stockpiling of spare power unit elements."
Wet weather starts
Following a downpour ahead of the British Grand Prix, the race was started under a safety car leading to a single file procession at the start of the first racing lap. Fans complained that they were robbed of a standing start and as a result the procedure for starting races in wet conditions has been changed.
"A new procedure regarding wet weather starts was also accepted," an FIA statement explained. "From 2017, if a safety car is deemed to be required for the beginning of a race due to wet weather, a normal standing start will occur once the track is deemed safe to race. The process will see the safety car return to the pit lane and the cars assemble on the grid for the start." [...]
to both!
