Just two cars deliver their advertised fuel economy when on the road, with the thousands of other models 30% worse on average in the real world, according to comprehensive new data.
Some cars, such as the Fiat 500 and Ford Fiesta, gave barely half the mileage advertised.

A company called Emissions Analytics published a database of MPG results using onboard equipment to measure mileage over four hours of real-world driving.

A couple of notes:
1. Since this is UK data, the fuel consumption ratings they're taking to task are the famously optimistic (unrealistic, some would argue) Euro ratings. They're significantly more optimistic than current US EPA ratings for the same vehicles.
2. The Fiat 500 is sold in Europe with a 2-cyl engine, which is probably the model in question here.
But the Fiesta is likely the same 1.0L turbo that is available in North America.

Oh, and the only 2 cars that matched their ratings in on-road driving? The 4.7L Aston Martin Vantage & 3.7L Nissan 370Z.
