I foresee very nervy times ahead for F1 engine specs. The next set of engine regs will last well into the 1930s to ameliorate development costs - that is if the engine regs from now don't just rolled over indefinitely until we know where we are going.....
Despite the astonishing efficiency of the current turbo-hybrid engines, they may become irrelevant as I believe that hybrid road cars will change from being considered EVs (huh?!) to being chucked in with ICE cars (petrol and diesel) and therefore banned in many countries starting around 2030. That ain't far away.. already the sales of hybrids are falling in some markets and quickly as diesels! That didn't take long for customers to realise that hybrids are a daft idea and were conjured up by current car manufacturers to hang onto their ICE technology.
As a F1 'petrolhead' for many years (decades even...) AND a green tech supporter/EV fan (I have a BMW i3 and charge it from solar as well as running the house off-grid), I am now bewildered where F1 goes in the foreseeable future wrt power unit. Eventually I suppose F1 will morph into FE Max (fuel-cell; battery; other?) but what happens for the next decade or more?
I certainly can see the social/political dangers of staying petrol BUT if F1 went carbon-neutral with all the freight; support vehicles/equipment/factories and spectators arrive in EVs, the F1 could make a case for staying with petrol engines for a spectacle and sport. The minimal percentage of petrol used for racing may be justifiable....hmmmm? There could be a carbon off-set arrangement (trees?)
A return to 1970s Cosworth (plus some others)-style simple, cheap and noisy racers....
Obviously this may only be a temporary solution as eventually it would be deemed too anti-social/anti-green (mid 2030-2040?) and wither on the vine...…..Then FE WILL take over as the premier World Championship, like it or not.
What suggestions do people/F1 fans have out there that are practical and realistic? No anti-green/anti-Greta/anti-EV rhetoric and tirades - that ain't gonna help. The Jeremy Clarkson brigade can pull their heads in!!
