Are diesels still superior to petrol-fuelled cars in terms of fuel economy?

I am new to Audi but love our new A5 SB. A few thoughts. We have a 2.0T 180bhp petrol. We are getting 44.1mpg over 6000 miles, and on a recent 1000-mile mostly motorway trip, got 52.7mpg. I am the passenger and a little out of touch, but when I drove a SAAB 9000 2.0 LPT I only got 32 mpg approx. I know the A5 is lighter but have petrol engines got that much better? I wonder if a carefully driven petrol car gives as good an MPG as a diesel?

Yes, turbo petrol engines driven judiciously can be very economical. Not much point in a diesel and all the risks they involve. I even got 28mpg over 700 miles from a 501bhp supercharged XFR.
