Mirror, a British online tabloid, has published the results of a study on actual vs. advertized fuel efficiency. According to the site, green cars are 25% less fuel efficient than what the automakers promise, which is rather surprising.
The Toyota Auris, similar to our Yaris, was the worst of the lot, averaging 4.42 L / 100 km while the Japanese automaker touts 3.33 L / 100 km.
Even the Prius is a let down. According to the results, it guzzled 4.18 L / 100 km instead of the 3.33 L advertized, a 16.2% increase.
Finally, the Lexus RX450h and Honda Insight both consumed 16.7 and 16.2% more than promised.
Four diesel engines and four gasoline engines were also tested and they proved thirstier as well, though their fuel efficiency numbers were much closer to what was promised. The Porsche 911 Carrera with PDK transmission is the one that came closest to quoted figures, only burning 3.7% more fuel.
However, these results should be taken with a grain of salt, as fuel consumption varies widely depending on temperature, vehicle maintenance and driving habits. What’s more, the tests conducted by government agencies may differ from the reality of most drivers.
For instance, Natural Resources Canada, who gives Canadians a point of reference with its Fuel Consumption Guide, establishes consumption ratings by travelling 16 kilometres at an average speed of 77 km/h without exceeding 97 km/h.
I don’t know about you, but I don’t know many people who cruise along at 77 km/h on the highway. So it’s really not that surprising to see that all vehicles are less fuel efficient than what the government and manufacturers say.
