The MPG tests aren't carried out on the road, so not having mirrors won't affect the figures. Although this link is for the US, I imagine that the EU uses a similar system.

"WHO DOES THE TESTING?</h3>
The testing is carried out either by independent test organisations, or by the vehicle manufacturers or importers themselves, usually at their own test facilities."Doing their own testing is just asking for manufacturers to find ways to exploit the tests. One thing they can do is to provide a car with an ECU programmed to achieve the best test results. How many do this?The tests are intended to provide purchasers with comparative information but they do not provide the confidence that this objective is realistically achieved.Red Move with sensor and winter pack.
