I thought the same about the ST on the motorway at first. I do a fair bit of motorway driving and it did get on my nerves a bit with the high revving and noise.
I had a 1.6 Astra before (wouldn't recommend it) and it was revving about the same doing 70mph as the ST.
But, The Astra would run out of steam when going a bit faster when the ST just keeps going.
A 1.4 Fiesta may be the same revs when doing 70mph but it wont go on to 130mph like the ST does.
I soon got used to it and love blasting the bigger cars
