Right. But there are only two methods, I suppose, NEFZ and 'the old one'.

So I guess the 2018 was measured using the NEFZ method, and the 2013 using the previous method. And I think the top speed is roughly hp@top speed / aerodynamic drag.
This new 2021(?) 1.2L car gets 4,9/5,0L/100 km, and a top speed of 160km/h.
This should also be NEFZ, in which case the economy is worse, and so is the top speed. Both could be explained by more drag by the new nose. If the latter is true this is a bad decision of Mitsubishi. I don't case about the top speed, as I never drive that fast. I don't actually care about the looks. I don't see it when I'm inside. But I do care about the economy. I feel it each time I have to fill it up.
But of course there are other possibilities. The top speed might be capped to meet some rules somewhere. Or the new engine management causes the engine to deliver less hp@top speed. And the worse economy could just be a side effect of the lower emission implementation.
