Just seen this in my TOPIx activity stream, I don't have the access to see details - it could just be a reflection of registering customers concerns. Any ideas anyone?TOPIx said:SSM72551 - AJ200D (I4D - Ingenium engine) fuel economy concerns.
I think you are dead right on this. Car manufacture set there car up to get the best test results. If the test reflected more how people drive then the difference between test figure and real life would be less.Comeinhandy said:The mpg you get shouldn't be a surprise if you had read a few car reviews, the DS is similar to its competitors. This is not a LR issue. It is an issue of the standard test not being realistic of typical driving, which is why they are planning to change it. On more powerful, less economical cars the real and official figures are more similar, it mainly shows up in much more efficient cars, where the mpg is much more sensitive to driving style.
Other manufacturers are no different. E.g BMW X3 20d combined mpg 54mpg, real world test 38 mpg
Merc glc 250d combined 56mpg, real world 39 mpg
