Stella on hardware changes to current F1 power unit rules
McLaren boss Andrea Stella says Formula 1 needs hardware changes to the current power unit rules, and wants major adjustments finalised within two years. Stella said: "Hardware adjustments to the power unit in order to improve Formula 1 in general, I personally think are required. They will have to do realistically with the fuel flow to increase the power from the internal combustion engine. I think they might have to do with harvesting more power than the power you actually deploy, because you spend much more time deploying electrical power, rather than harvesting it."
