is it too close to the current model?

for example, i don't see so much difference outside. also, new engines only improves milelage, and the S model is still using 1.6 engine. even peugeot 207 is using a 1.6T, not even a very high class model. opel astra OPC will have 200(+?)hp and renault clio RS already has 200hp. the MINI seems doesn't have significant difference to the old one.

would anyone plz explain that if you know?
