Some news that won't be received well by Honda.
One of the fiercest battles off the track in Formula One last season was the ongoing struggle between Mercedes, Ferrari, and Red Bull Renault in regards to developing their engines during the season. This became a top story as teams scrambled for any way possible to close the gap on the silver arrows.
As revealed by Autosport, the FIA is now saying that teams are no longer locked into a single homologation for the year, due to a loophole in the rule book. They may test and implement upgrades throughout the season.
Mercedes loses a little of their advantage
This is a blow to not just Mercedes, who will lose some of their edge, but also Honda. Being a 'new' manufacturer, they must have their 2015 power unit homologated and locked in by the end of February.
The engine freeze was originally put in place as a cost-control tactic with changes only allowed if the FIA agress that it falls under a reliability, safety or cost-saving issue.
