To say that the 172 is old hat when it comes to hot hatches is wrong IMO.
EVO had the 172 as its best hot hatch for ages before the cooper s came out.
Its true that these new cars that somehow have gotten into the hothatch category have ridiculous amount of power compared to the old ideals of hot hatches.. this being a small car that handled superbly and has enough power to enjoy the chassis.
Cars like the CTR, RS Focus, Alfa GTA really go against the original idea of the hot hatch. They have masses of power and weight also.
Maybe were seeing an evolution of the hot hatch... Im not convinced its for the better though.
