Do I see future for PHEVs? Not really because adding the combustion drivetrain with its costs, maintenance and fuel use loses as battery prices go down.

But there's this too: they use massively more fuel than tests assume.

In practice this means 2-4 times more fuel pipe emissions of CO2 and NOx than currently assumed. And switching to WLTP doesn't really help either (and the ICCT agrees with me).

So if tests would be based on reality instead of the laboratory, this would be really bad for PHEVs.

And there's good news on the testing front. It seems the EU might be moving to reality based testing. Also the is more and more on road testing by institutes like @TheICCT informing policy.

I cannot emphasise enough how important it is that we stop using #faketests to determine CO2 and NOx emissions. Once policy becomes based on reality, it will make the advantages of BEVs and the disadvantages of PHEVs en ICE-cars much clearer.

Also, I think most politicians and even car manufacturers are tired of all the energy expended in cheating. It goes on and on and on. All that energy could be spend on improving the technology and saving lives.
