I don't share the opinion that a way forward is in making cars basically same aside their look. In fact I don't like that at all. By that motorsport looses one of its fundamentals which is the engineering genius. Already the existing rules are making all cars basically same. The size, layout, main functional things, all operates same way in all WRC cars. The differences are in particular details but in nothing major. That's exactly opposite to how it used to be in the past. Mini bringing small nimble FWD to victory, Audi bringing 4WD or semi-automatic gearbox, Lancia bringing mid-engine RWD or two-level supercharging, Peugeot bringing mid-engine 4WD... all that and much more would never happen if the rules fix all cars in the same scheme.
