Small power reduction to some high performance petrol engines

[Booth11]

Can someone please share on the Rforum........

I am banned from there still I think 

Yes, will do.  The ‘R’ is actually missing from your original post.

S3 is down to 300 too.

(a whole second of difference at 200km/h means several cars length in between the two cars).

Surely that only matters if you're racing?

Probably... same as any power or acceleration figure only matters to racers usually 

No need for concern for road car drivers then. However, if having to brake from 120 rather than 118mph to the McDonalds roundabout is an issue, then perhaps it should matter.

Saw this: http://www.autoexpress.co.uk/volkswagen/golf/103993/volkswagen-golf-r-power-dropped-down-to-296bhp-due-to-wltp-emissions-rules

Also says no more 3 door R. Is this the beginning of the end?

Evo taking about the reasons and how the power decrease is happening.

Funny that it doesn’t say this is a step back to the same power as the original Mk7 R?

Absolutely no concern at all. We know anyway that people usually pay the premium for 300bhp cars instead of the lesser variants to only ever accelerate in a calm controlled manner, always stay below 70mph and never engage in any sort of "testing" against other cars. Makes sense that no R owner/buyer would care about acceleration figures, first thing they check is usually mpg

From that Evo link:

"Essentially the power loss has come from the need to fit a more restrictive exhaust to reduce nitrogen oxide emissions – something more stringently policed under WLTP. "

That'll be the particulate filter then. Do I win a prize?

"SEAT also recently went through a similar process with its Leon Cupra."

Golly, how strange, an entirely separate car manufacturer with the same problem and solution.

On a serious note, will that be really an extra part of the exhaust (filter) or it is rather a more restrictive catalyst? Because from the wording used it is not clear what's the case.

[fredgroves]

Petrol particulate filter.

When they introduced those to oil burners with Euro5 the performance dropped right off.

It took a while for better designs and other changes to bring it back, which they won't do for the Mk7.5, this is just an emergency retrofit. Mk8 should be better...

I'd imagine that much like the earlier oil burners, removing the PPF will see quite good gains, but I'd imagine that's a MOT fail...

Just checking out these posts about the R.I was shocked to see the first year VED for a manual is £800!.DSG £500.I know it's £140 a year thereafter but that's a total rip off!.Maybe the lower emissions will make a bit of difference.
