Hmmm interesting. So right now the tech "stops" on the RE-X1 car or if manufacturers had more room to play around it could be at Rally1-ISH levels? Considering the weight-performance-safety balance... Like, are the current tube frame cars lighter?
Alone they are slightly lighter but not with the 84 kg heavy hybrid system. With it they are actually heavier than the previous generation of WRC cars (30 kg more total weight).
Answer: NO
WRC Regulations
17.1.1 Each Manufacturer must use no more than 2 engines per car
name per season (see also Art.17.2.2 and Art. 17.2.3).
But
17.2.3 When a car does not finish...
Where do you set the limit?
Do you allow a new engine and a new gearbox on every day of every event?
Using your figures that would be €1.5 million in engines and gearboxes every event!
The WRC has some stupid rules.
The manufacturers spent 60 miilions a year or more to win titles, and then they limite engines to only two?
A third one would blow the budgets? Seriously?
...
Aren't engines linked with certain chassis numbers?
