The compression rate in each cylinder of the 1.6-litre V6 hybrid turbo engines has been limited to a 16:1, down from 18:1 under the previous set of rules.
But the current rules, specifically Article C5.4.3 of the regulations, say compression ratios will be tested “at ambient temperature”.
Mercedes is rumoured to have circumvented this rule by reportedly using materials that can expand in high temperatures, increasing the compression ratio of the engine, but will pass the inspection when cooled down.
