MHT
Anyone know why the petrol G20/1 models don’t get MHT? Can’t be a limitation of the car size as the diesels have it. Can’t be a limitation of the drivetrain as the 520i and 530i have it. Seems that the 3 series petrol are the only models that do without, other than the M340i

I have a theory: I bet on “dirty” diesels and the 6 cylinder petrol the addition of MHT is sufficient to bring the car in to a lower WLTP emissions bracket. On the heavier 5 series, even on the petrol, it also brings it down a level. I suspect on the 4 cyl petrol 3 it stays in the same bracket to BMW haven’t bothered.

It's all smoke and mirrors. Power wise, does a 3 litre straight six turbo engine need MHT? Nah, course not. Does it look good on paper and economy? Sure! Presumably that engine (or something like it) also now has a 15 year life span, as I guess it counts as a hybrid to 2035 when all combustion engine cars (hybrids too) go end of life.

I realise it’s all bollocks but my question really was around why the diesels get it and petrols don’t. As to whether there is any real benefit to either is a moot point.

But my G21 is registered as MHT and has the animated power flow screen to prove it. Apparently it's mainly used pulling away from standing start. |
