What's the Fiesta ST like on the motorway?

I've got a Fiesta 1.6 petrol Zetec S which does 95% of what I need a car to do. One thing it isn't great at is motorway cruising. It's happy at 60mph, working by 70mph and really not all that happy at 80mph. Is the ST any better? I'm thinking of getting the Focus mainly for the extra motorway driving I'll be doing, but the Fiesta would be the car of choice for most of the other driving I do. Stuck between two stools really.

I'm talking about the new one. I wonder if it will be quieter with the six gear and extra power. Not too worried about the mpg.
