From spectator's point of view You are right. The problem is that such wish isn't realistic. Atmospheric engines are a dying kind now. Car market is driven by low-emissions, low consumption, pedestrian safety standards (that's also one of reason why to go for small engine) and blabla. That's why carmakers one after another goes for small turbo units and therefore these naturally get also to all sorts of competitions.
I don't like it but who cares about me. Now nobody cares how long a thing like 100 kW 1.0 engine can last. Where are You going to find someone to repair a second hand hybrid? Yeah, it works like something from a PC game, has nice displays with all the stats, graphs and other playstation-like features but who the hell is able to keep that damn thing running after ten years? Almost nobody even makes new downsized engines suitable for major repairs. Cars are getting more and more just a goods like a fridge, TV or smartphones. How come that You can use 15 years old Civic VTi for competition without any major rebuilds during whole season? I shall stop crying... :)
