UK: What Car? ranks "real MPG" of small petrol/gas cars, Mirage places 3rd

Real-world MPG: most efficent small petrol cars

-- We name the most efficient small petrol cars
-- Results indicate real-world fuel economy

We test new cars’ fuel economy every week at What Car?, but unlike the laboratory-derived government data, our True MPG technicians gain the numbers from driving in real-world conditions, to bring you realistic MPG figures.

The top 2 spots go to twins:

1) Peugeot 108 (1.0 VVT-i - official mpg 68.9 True MPG 54.6mpg) and
2) Toyota Aygo (1.0 VVT-i - official 65.7mpg True MPG 54.0mpg)

3) The Mirage is the top 1.2L car: official 65.7mpg True MPG 53.4

Unfortunately, like many in the UK media, they don't really like the car itself aside from its good MPG:

Every version of the Mitsubishi Mirage emits less than 100g/km of CO2, and the little car performs admirably in our real-world economy tests as well. Unfortunately, that is about the only strong point for the Mirage, as it falls short of the competition in almost every other area.

I didn't bother to dig and see what type of route/techniques/speeds they're using to evaluate the mileage.
