I don't know about the specific cars you mention above, but if it helps at all I had a Toyota Corrola estate for a 2 day hire a week ago and it was returning between 65 and 75mpg dependant upon the style of driving. It returned better MPG pottering around the backroads A/B roads with lower MPG on a long motorway blast. There was plenty of grunt, but it definitely is NOT a sports car.
The electric/petrol switching was utterly seamless and if you don't watch the rev counter it was impossible to know what power was being used. It really was a great car, loaded with tech which is usually reserved for £££ options on higher spec cars (adaptive cruise control for example), the problem is that it was as dull as 4 week old dishwater. If it were a colour it would be magnolia. Absolutely nothing about it made you smile or enjoy the journey. In nearly every way it was brilliant, but it was a car you buy with your head/wallet and leave your heart behind.
If you want a hybrid, try the specific ones you like the sound of and see what you think, as they all have their individual 'quirks'. The noisy gearbox on Toyota hybrid's being one of them...
