It seems there’s a rising concern for fuel economy ratings, to no surprise, as it’s become a major selling point for new cars around the world, thanks to tightening government regulation.
First, it was Hyundai and their inaccurate fuel economy ratings for being overstated and now, Mercedes-Benz was found to have overstated some of their fuel economy tests as well. A new study was conducted by the Transport & Environment group in Europe and they allegedly found that some Mercedes-Benz cars consumed around 40 percent more fuel than what’s written or advertised. The average for all automakers in the study was around 31 percent.
As a result of this study, Transport & Environment hope to make fuel economy ratings more accurate for customers, while forcing car makers to make their cars truly fuel efficient.
