Mercedes team principal Toto Wolff insists their engine is legal and that its design has been approved by the FIA. <\/p>\n
The compression ratio is a measurement of the cylinder displacement between the two extremes of the piston stroke. Rivals believe increasing this beyond 16:1 could give a gain of as much of 0.3 seconds per lap.<\/p>\n
Williams team principal James Vowles, whose team use Mercedes engines, dismissed the debate as “just noise that will probably go away, probably in the next 48 hours”.<\/p>\n
Red Bull’s position on the compression ratio argument has not been clear until now, following their entry as a power-unit manufacturer this season.<\/p>\n
Red Bull team principal Laurent Mekies said on Wednesday: “We don’t think it’s noise. We think we must have the clarity on what we can and cannot do.”<\/p>\n
The new engine proposal came on the same day as the F1 Commission discussed a variety of issues that have arisen from the first running of the cars under the new rules introduced this year.<\/p>\n
These included the increased difficulty of the start process and the way energy deployment and recovery are controlled by the rules.<\/p>\n<\/div>\n
