Marko: TD ‘backfired’ on Mercedes, must solve their own issues

On the eve of the Canadian Grand Prix, the sport’s regulator announced a change in the rules which was designed to limit the amount of bouncing the drivers were being forced to endure.

A statement from the FIA read: “A Technical Directive has been issued to give guidance to the teams about the measures the FIA intends to take to tackle the problem. These include:

“1. Closer scrutiny of the planks and skids, both in terms of their design and the observed wear.

“2. The definition of a metric, based on the car’s vertical acceleration, that will give a quantitative limit for acceptable level of vertical oscillations. The exact mathematical formula for this metric is still being analysed by the FIA, and the Formula 1 teams have been invited to contribute to this process.

“In addition to these short-term measures, the FIA will convene a technical meeting with the Teams in order to define measures that will reduce the propensity of cars to exhibit such phenomena in the medium term.”

That one team was Mercedes, who raised suspicion when they appeared with a different floor during one of the practice sessions before swapping it
