the exact, same 2004 engine regulations, with only one twist. Open up spark mechanisms. im sure manufacturers can and will come up with something much better than the current spark plug.
these engines were making 980hp with 2004(!!!!) technology. A modern V10 will no doubt be around 1200hp with all the juice, without throwing billions at it. How much does a complete HYBRID Power UNIT costs? was it around 30 or 40 MILLIONS?
How much can a V10 cost? With
another thing that is a modern argument, the road relevancy and leading tech fairy tale. From a road relevancy standpoint the hybrid V6s are a failure, no road car has an MGUH, MGUK aside from few exceptions. The ONLY road car to have an MGU H is the AMG ONE and it's not that grand anyway, heavy, relatively underpowered, the Valkyrie is a superior machine. I vividly remember browsing some F1 forums back in 2010, 2011, watching races, etc. I NEVER saw the words "road relevancy" come up in the screen, somehow few years later all you hear is the same thing over and over.
Then come complex fuel formulations that wont make the street market, this is also pointless, it's all a tale, since when F1 was supposed to be the place to test technologies to THEN be brought to road cars? as I said, I have never heard of such thing until few years ago.
lighter and raging cars are the way to go, it's what "open-wheel formula" has been about since its inception. Cars are bloated, heavy, all thanks to current PUs, when you have FORMULA 1 cars LONGER than commercial trucks, it's when you start to realize somethings odd in the formula. (pun intended)
