I thought initiatives like WLTP were designed to harmonise test results across all manufacturers? Whilst it’s understood that real-world driving will mean WLTP figures are better than can be expected in reality, at least the playing field is level? Let’s be honest, no-one here has bought a car that says it does 65mpg and been surprised reality is closer to 45mpg, have they? And yes, I know there are worse examples but that quoted 65mpg is only achievable if you live on perfectly flat ground, where there’s no wind or rain, you don’t have a heavy right foot and can continually drive at 56mph everywhere.
There should a test for BEV’s, which take into battery temperatures with/without heatpump into acount during the colder seasons, that account for the plumet in range which can be as much as 40% or more depending on the model.
However the article is about Tesla algorithm to make the cars sound as if they go further than they actual do, which as I understand WLTP takes into account as their base line. Similar to VW dieselgate!
