GTI engine - German x Mexican

[Andrei Mattiuzi Balvedi]

Hi everyone!

For about a year now, VW Brazil has imported the MK7 GTI from German; but from now on, it's gonna be imported from Mexico, until the new VW facilities here in Brazil start to produce the MK7, which is to happen late next year, I suppose.

Well, looking at the mexican VW site and at the GTI specifications, I realised that the power and torque are the same, BUT they come in a (very) higher engine speed compared to the german version. I mean:

German GTI: 220ps@4500rpm, 350N@1500rpm
Mexican GTI: 220ps@6200rpm, 350N@4200rpm

Why is that? No Valvelift in the second variant?

I would really like to know, because I'm quite sure VW will omit this irrelevant information...

Cheers

To meet different markets emissions maybe?

Seems very strange would be interesting to see a dyno, maybe emissions, may just be a Mexican typo but it'll be the same hardware so a simple remap should yield the same results you'd hope

I wonder if it's related to fuel specification? Although agree seems odd.....

[Andrei Mattiuzi Balvedi]

Someone told me that maybe they might have informed the max rev in the range where max power and torque are reached, and not the min rev  Possibly that. Wrong way to tell things, tough.

Anyway, US specs show normal GTI with 210hps and Performance Pack with 220hps

I know there has been a lot of talk on the US forums about the lack of port injectors on certain US GTI engines......so I'd guess having 4 less injectors is probably the difference.

i thought that was just emissions, a mapped us gti and a mapped uk gti are the same arent they?

[monkeyhanger]

Could just be the RON91 petrol they get as standard low grade in the US, they have to tune the engine to run on that as a minimum?

[corgi]

One of them must be wrong... because power is directly proportional to torque x revs...

So the same torque at different revs means the power must be different...

[GrahamFR]

they mightve got a good deal on some ex demo mk6 engines....
