How Accurate are MPG Figures?
October 30, 2014
As we all know, high gas prices are here to stay, which means fuel efficiency has become an important factor when it comes to choosing a new car. However, consumers need to be aware that the MPG shown on a car's window sticker may not be completely accurate. Consumer Reports recently conducted a study to see how accurately the promised city, highway and combined MPG stood up in the real world.
At the top of the list is the Honda CR-Z EX, which according to Consumer Reports promised a 34 overall MPG and performed better with an experienced overall MPG of 35. And on the other side of the spectrum is the Lincoln MKZ Hybrid, which fell 11 points short of its promised 45 combined MPG when tested. Below is a look at 19 vehicles tested by Consumer Reports and their results.
