I've got in touch with someone who attended the ImechE conference I've mentioned in the previous posts. Did not manage to get any of the presentations but I was provided with a very good summary:
FIA has contracted IFPEN Transports Energie Carnot Institute (https://www.ifpenergiesnouvelles.com/in ... -institute
) to study different options for future F1 PUs. FIA's initial guidelines suggests ultra-downsizing to roughly half the current engine displacement. Fuel mass flow and on-board fuel will halve. BTE target is set to 60%. Emission regulations and P4 hybridization with front axle recovery have also been suggested but do not appear to be firm targets.
Technologies proposed to achieve these objectives include:
-Removing the CR limit
-HCCI and spark-assisted HCCI
-2 stage supercharging
At the moment they seem to be leaning towards keeping the MGUH.
Teams are expected to feed back which of these technologies they would like to pursue. As manufacturers start finding common ground the regulations will start to firm up.
This would suggest that in future they continue the same race for more efficiency and performance as we have seen the past 6 years. Any idea’s how prevent another expensive development war? I doubt that current manufacturers or any potential new entrant would be interested in burning another bilion each.
I do believe that MGU-H or another form of Exhaust Heat Recovery is still on the table. Porsche preferred it over front brake recovery, for the 919 WEC racer. Exhaust Heat Recovery is very efficient, smaller, lighter and also not influence the feeling of the front brakes.
To bad it’s also a big muffler...
