Today’s a day where sound seem to be a theme and now we’re dragging you into it. Part of being a dedicated gearhead is an appreciation of the many ways that cars, trucks, and other mechanical devices interact with all of our senses. Hearing is an important one when it comes to engines. From the glacial RPM scale of an old tractor engine to the incredible roar of a blown alcohol mill, they all have an auditory signature. Some of those are more flowery and complex than others.
Mostly based on personal taste, this question is one where a general consensus is virtually impossible to achieve. Sporty car guys will speak whistfully of the shreik that small cube engines in old European road racing cars make, import drag racers lovingly talk of rotary engines that many people plug their ears for, and oval racing fans stand pat on the basso rumble sent forth by the headers on an alky injected big block hanging off the side of a Super Mod.
You can give the cop out, “I love ’em all,” line if you want to look and sound like a weiner. Otherwise, man (or woman) up and tell us loud and proud what the best sounding engine of all time is!
