Red Bull's Helmut Marko has questioned the FIA's recent claims on the performance convergence of Formula One's power units.
As part of an agreement to continue with the current engine regulations until 2020, F1's manufacturers agreed, among other targets, to encourage performance convergence this year. In order to help rival manufacturers catch up with the benchmark Mercedes power unit, the token system -- which was designed to keep costs down by limiting the amount of performance upgrades a team could bring to its engine -- was scrapped.
To help gauge whether the removal of the token system was having the desired effect, the manufacturers and the FIA agreed on a formula -- to be calculated by the FIA -- that would assess the level of convergence after three rounds of the 2017 season.
