You couldn't be more wrong. Especially when we are talking about Rally1 cars which are tubular space frame prototypes while Rally2 (and WRC) are built from a production chassis. The engines are quite different, and so are the transmissions and suspensions. Rally1 and 2017 WRC has much improved safety and the transmission is designed to withstand higher power from the engine.

Performance wise a Rally2 car is probably nowadays close to a 2011 WRC car. But it's still more costly to run a 2011 WRC car in a rally.
