FD1 - 1.8 -> acceleration is good poor fuel consumption
FD4 - 1.6 -> compared FD1 acceleration is low (For some people its not enough as they expect performance from a Civic)
FD3 -> You buy a Hybrid for a better fuel consumption but its not that economical compared to other Hybrids. So due to avoid extra maintenance people try to avoid FD3 and go for a FD1 or FD4
