German Engineering at its finest

[Abott10]

VAG in a word.

Another superb ploy to fool the emissions probe...

The Germans are 100% at it, Mercedes are doing this as well.

Not on the Mercedes Megane "A Class" yet, but I am sure it will be featured at some stage !

Come on! It’s not to get round the emissions test, it’s pandering to people who want their car to look from the rear as though it’s got 400 bhp. I am thinking of something similar on my diesel cart to stop people overtaking me. Six pipes sticking out the back should stop even the ‘stupid’ brigade having a go.All flame red so they don’t miss them. .

did I read on this forum (I think) a few years ago, that the turned down pipes were part of the Euro 3 regs, to try to disperse diesel fumes?

Curved pipes!??
Can't be an EU rule. Too stupid.
They only rule on curved cucumbers! Surely?

No, no no! You have to let them overtake you to begin with; then power past them on the next straight as if they weren't there. Then, slow down, and do it all over again so they know it was no fluke!

Leastways, that how I used to do it, when barrelling along country roads in Portugal. Golf GTi's in particular were always game for a laugh then Mind you, I was in the M5 then... Well, I can always dream, though I have to say my 160hp tourer diesel is fast enough for now... As my old father-in-law used to say, he aimed to be the oldest on the road, not the fastest!

There's an interesting note on this site:

https://www.dpfproblems.net/cars-without-a-dpf/

".....BMW’s also have a cosmetic method of identifying whether a Particulate filter (DPF) is present, assuming that a standard non modified exhaust is fitted, BMW cars which have straight exhaust tailpipes have DPF’s fitted, those without DPF’s have a tailpipe which points slightly downward...."

Bizarre but, apparently, true.

That is correct on the early years when certain cars had DPFs. The BMW M47 diesel engine (sounds familiar?) had an option of of a DPF. The old M47 engine that didnt have one was identified by having a downward pipe like all diesels to stop the rear of the car being covered in soot. The larger diesel engines from 2004/5 had a DPF such as the 325d and 330d. In 2008 the N47 was introduced to replace the old M47 engine and that had a DPF as standard. The problem with the N47 engine was timing chain rattle at approx 100k which meant an engine out job as the chain was at the rear.

German engineering at its best?
Mercedes 560SEC.
And most likely the best car ever built, in my humble opinion.
From before the world went mad.
