2019 golf R power reduction

(1/3) > >>

csrigo:
Been away a while and I've been looking into some new cars.
Question is how have VW reduced the power in the 2019 R compared to the 2017 310bhp etc? I've read it's down to the exhaust but is that all?? Have any engine internals changed etc? Is it using the same engine...same engine code...310 bhp vs 297 bhp or whatever it is now?

I'm looking at either a 2019 golf R or possibly pushing the boat out to a 2017 rs3 so need to all the info I can before I take the plunge.

Cheers

They now have to use a particulate filter on the downpipe due to WTLP emissions regs. Think it has been retuned for more torque though,

Cheers mate yeah I had read the same...also read somewhere that the injection system was different and possibly the exhaust valves within the head...maybe just some wrong info someone has posted as that seems excessive to drop 10bhp...

colesey:
Iirc the USA cars had a different injection system so maybe that aspect has crept into the mix. The resulting 3% power drop from fitting an extra catalyst device seems quite plausible given gains from sports cat upgrades and is consistent with gains typically claimed for precat deletes on the Mk5.

pudding:
I wondered when petrol engines would be targeted for soot filtration! 

I would stick to older cars personally because all of this nonsense is only going to get worse in the next 10-20 years.

I think my next project will be a MK6 R with the second gen (all alloy) TTRS engine.  I don't really like the backwards changes on the MK7s.
