Paul - Mazda's current crop of petrol engined cars are N/A (normally-aspirated - no turbos) lean burn engines, and as such are reasonably comparable in real world driving - check the 'Real mpg' section. Realistically only the VAG TSi petrol engines get the closest to their claimed (unrealistic EU test) mpg figures - those for, say, Ford's Ecoboost engines are much lower.
Comparision of engine performance and mpg (approximately)
Mazda high powered 1.5 petrol (115hp Sport in the 2) = VAG 110hp 1.0/1.2 TSi
Mazda std 2.0 petrol (120hp in the 3/CX-3 & 145hp in the 6) = VAG 110hp 1.0/1.2 TSi (Golf sized cars) and 120hp 1.4 TSi (larger cars)
Mazda high powered 2.0 petrol (165hp Sport in the 3/all in the CX-5) = VAG 150hp 1.4/1.5 TSi
The VAG TSi engines are about 5-7% better on ave. on mpg than the Mazda 'equivalent' performance engines and are a bit more peppy on mid-range acceleration, but in the Mazdas favour they (petrol engines) don't have a turbo (to be fair, most VAG petrol turbos for their lower powered engines seem to be quite reliable) but more importantly are ALL chain-cam driven, so no costs for belt replacements, and will be more reliable long-term if kept well-oiled in line with the manufacturer's guidelines (12.5k miles/1 year [whichever is achieved first). Bear in mind that the KIA big cars won't be any more fuel efficient than the Mazda equivalents, maybe less so if they have their older spec N/A engines. The KIA/Hyundai 7/5yr warranty is well regarded though.
The VAG 1.4/1.5 150hp engine is very well regarded (not the 'old' turbo and supercharged version though) and generally commands a price premium. For me, its the rest of the VAG engineering and customer service that, to varying degrees, has put me off buying one as yet.
Lots to weigh up I think. Best to make a list of 'must haves', minimum specs and performance (be as realistic as possible) and check out other factors that are important via the reviews, including user reviews and the 'Good & Bad' section of each car's review - they can give a flavour of issues that can never be picked up on a brand new car's media review test drive.
Also bear in mind how long you intend to keep the car and check out the local dealers, including reviews of them, some on this website in the Good Garage guide section:
good-garage-guide.honestjohn.co.uk/
...and on other websites. You may find a local dealer isn't well regarded, and may put you off buying a new/nearly new car if the next nearest dealership is too far away/not near work, etc.
I had a similar problem as you finding a decent small to mid family sized TC (non-DSG type) auto car, and nothing really stood out as great, so (and for other reasons), I stuck with the Mazda3 1.6 petrol manual I've owned since new for (now) 12 years. Like I did, do as much research/get good advice as you can and don't rush the search - you may have to compromise to some degree, especially on the performance/mpg side if you don't want the risk of a potentially less reliable DSG type auto box.
