Hi there,
Has anyonenoticedthe samedifference as me on exhaust note between early published clips (from test drive in Slovenia) and new clips (captured using cameras mounted on mass production car). Check below

Clearly a "pop" or so called "burst"whengear up

No "pop" whengear up



Did Merc or AMG change something on this?

Personally, I would prefer the one with "pop" since it makes you feel the car is more sporty.

yeah have noticed before that not all clipshavethat, but many reviews have commented on the 'boof' or 'bursting' on flat out up shifts ....i dont think anything has been changed. I just put itdown to the fact that maybe the conditions arent right?? sports mode/revs/quality of micetc etc??



Mbznut or anyone elase with an engineered will confirm soon im sure...

Mine doesn't pop going up the box only on over run and going down the box, turbo gets quite vocal though. Might get better with more use or warmer weather?

cheers fella ... love over run pops.So glad i wont be losing that going from the scooby. Granted it might be quieter on the a class but nonetheless i'm chuffed to have some pops!


what about the 'boof/boom/bursting' on up shift??(or the fart as seem people like to call it). A lot of reviews mention it, and as per the clip round the old airfelid in slovenia ...



Similar to Golf DSG up shift noise.

All I can hear when going up the box is turbo. It might sound different from the back? Down shifts in sport mode sound great and the auto box is much quicker than I thought it would be

Then looks like the "pop" or "burst" sound when up shift has been dropped by Merc.


The clips from Slovenia test drive are only sources we could hear it from.

There are several reivews which mention it ... i had pasted extracts from them last night but my internet explorer crashed and i lost my post,but here are some now:


'Under the bonnet the Sport gets an overboost function that adds 11kW at throttle openings above 4000rpm. The function delivers the extra power (but not extra torque) for up to 30secs. A new muffler and modified exhaust design delivers the trademark 'boof' on gearchanges that the GTI set so cherishes'



'The gear changes are also quicker in the A250 Sport, followed by wonderful exhaust blow-offs that reminds you of the VW GTI'




But on that slovenia clip there is a comment from someone saying their engineered does not make that sound either.



And on another Youtube clip there is a further comment saying that their engineered doesnt burst either.



All very interesting .... something fishy is going on it seems lol ...



In fact. if i remember correctly, one of the official mercedes adverts for the engineered also subtly includes that sound it the soundtrack ... if i can find a link i'll post it.

I sent Merc an email about this ... and laid it on a little thick. Judging by their reply, they either think i was complaining about a fault?? or they're suggesting that the test cars may have had a fault?? im not sure really ....





'I am asking this question on behalf of many avid fans/owners/and potential owners of the Engineered by AMG. We are all memebers on the same forum.

there is a clear difference with the exhaust note when in sport, not sure I am going to risk death by trying to record it.. it is far more noticeable with the window open in a tunnel.. floored it in the Limehouse link and def. noticed the bursts.. but couldn't quite get up through all the gears due to the speed camera at the end
