Thanks, I hadn't fully read the VWroc since early Jan, so I'm up to speed now, I agree, seems like a storm in a tea cup.

Just curious what the overall consensus is on this, if for instance buying a 1-2 year old GTi or ordering a brand new one, is loss of MPI really a deal breaker?

How much are you going to use it and for how long? I'd sooner take my chances with a new car than a secondhand one - who knows what problems you are buying - why take the risk if you don't have to?

If you are thinking resale, most people won't know the difference. Its going to make bugger all resale value drop.

Meh petrolheads storm in a teacup.

Just had confirmation via the Polo forum that MPI on the Polo GTI's 2.0TSI engine has retained MPI after becoming WLTP compliant with GPF (post October build). Pictures seen that show the expected MPI specific components are still there. Makes it even stranger that Golf GTI has lost it and the Polo didn't. I wonder if any other VAGs using that engine have lost MPI?

A golf is heavier than a polo... Heavier is more polluting. I'd guess the polo doesn't have the gpf... In the same way as previously the oil burning passat had adblue but the golf didn't (does now...)

Not sure about all of the Polo range, but the WLTP compliant Polo GTI/GTI+ with a 200ps version of VW’s 2.0 litre EA888 engine does have a gpf, as well as retaining dual injection / MPI following WLTP certification.

The Golf isn't that much heavier than the Polo - the Polo GTI+ is about 56kg lighter than the new GTI Performance. My pre WLTP Polo GTI + doesn't have a GPF, the WLTP compliant one that started building in November does.

The Polo is marginally smaller than the Golf now ,- same interior size, shorter bonnet (Most of the difference) and slightly less deep boot.

There really isn't much in it at all.

I can't figure out why they'd have two versions of basically the same engine - one DI only, the other port/DI. Doesn't make sense.

56kg can make a lot of difference, plus its not just weight now WLTP is "real world" testing.

I've no idea what their aim is either for WLTP figures, but its more than just "we want a Golf to be xyz g/km to make the road tax figure right" its more to do with their attempts to have a lower fleet CO2 figure.... If they sell more Golfs than Polos (and they do by a massive amount), they will need to get the figures down on a Golf far more than a Polo or an UP!
