As long as we're talking about exhausts and engine sounds, which it always seems we are, can someone explain to me what exactly it is about a v10 that they like?
To me they sound like cement mixers at low RPMs. I remember from the mid-90s when the viper first came out all the reviews talked about how they sounded like garbage, a result of the inherent imbalance in a v10s (and I am aware that bank angle played a big role in the Viper sounding like crap as explained here
). I get the arguments for i6, v8, v12, heck even v6, but I don't get it for v10.
Once you get to high enough RPM, it's pretty hard for me to distinguish between engines but at lower rpms where you can more or less hear the melody, I tend to agree with the orthodoxy that v12s and i6s sound the best, but that v8s have their benefits too. No one likes a 5 cylinder engine and sticking two of them together doesn't seem to change that. Some of this can be difficult to unpack because exhaust tuning has a huge impact and at higher RPMs it can be really difficult to discern the tune. I'll say it again for emphasis, but I prefer my lopey 15 year old domestic v8 at low RPMs to an M5 or Gallardo because the v10s sound like they have a misfiring cylinder. LFA is a bit different because it has a 72 degree bank angle which helps balance things but none of the other V10s people talking about have that feature because they're mostly 90 degree v8s with an extra pair of cylinders grafted on.
I realize this is outside the scope of the thread, but ramu next time you do an engine sound comparison can you create some sort of web interface where we can see the RPM and decouple the engine sound from the exhaust tuning? Bonus points if you can include spectrum analysis. Extra bonus points if you could let us choose under load or not. Maybe ramu and GF can go into business together to create the ultimate engine sound web app and live happily ever after.
Also, one more question - Pio - do you pay attention to fuel economy at all? I'm wondering if your new GL is any more fuel efficient in practice than your old one? My X1 is listed at 25/33 and my wife (who drives it 90% of the time) typically average 24 miles per gallon in mostly HWY driving. Her previous car was 23/32 (pre-2008 so it would probably be rated 21/30 today and naturally aspirated of course) and she averaged more like 27 with the same mix.Edited by UnFacconable - 3/13/16 at 10:46pm
