I don't get what your trying to say though? Just sounds like nonsense tbh. The Clio's power is all up on the higher rev? So a diesel staying with it if your under 5K rpm is completely irrelevant? Why would you race something when your not even in the right gear. That's the same as implying an Astra vxr is slow off boost? Or a 600Hp car that only makes 350hp under 4K Rpm? It's the nature of the engine. It's just lazy if your implying you accelerate in higher gears and under the powerband. Different engines/ different driving style.
Fair enough if you said 'the fiesta suits my driving style' but my brothers corsa vxr I find boring, I love a high revving n/a, love working an engine. So it's all down to preference. It's hardly asthmatic...
The fiesta is rubbish after 6K rpm? So is that asthmatic, whereas the Clio keeps revving and comes alive.
Just your points sound completely irrelevant.
