The Great Sounds of the Automotive World

To me it sounds like a straight 6 that's been possessed by the devil.

Well, technically it is like 3 straight sixes firing simultaneously - 6 6 6

*Edit: I'm not sure if the 20B fires all rotors simultaneously or if they are phase shifted. Maybe @Griffith500 would care to shed some light on this.

GT40

I never really liked the GT40 sound all that much; the manifold design makes it sound like a big cube, low revving, (flat plane) Ferrari 348 with wild cams.

Nothing like the sound of a good old ported rotary.

Remember that Mazda rotaries use a 1:3 ratio for the eccentric shaft. So when the rev counter is reading 9000rpm, the rotors are spinning at 3000rpm. But since there are 3 firing events per rotor, it sounds like 9000rpm.

The 13b has a 180 degree crank which translates to 60 degree difference between the two rotors' firing pulses. I believe 20bs are even fire with 120 crank rotation between firing events, which means 40 degrees at the rotor. So what you hear is 40 degree firing intervals. For reference a V12 has firing events every 30 degrees of crankshaft rotation, hence the smooth, deep, and complex tone.

Put another way, at 9,000rpm, a 20b is doling out 27,000* ignition events per minute (if you count trailing plugs, that doubles to 54,000 ), which is equivalent to a 4 stroke 6 cylinder engine, which is why they sound similar.

*[360* full rotation/40* rotation between ignition events x 3,000rpm rotor speed @ 9,000rpm = 27,000 ignition events per minute at 9,000rpm]

I didn't even know that. Thanks for the explanation.

That turbo noise!

As much as I love n/a engines, that one is just too small and too high revving for the relatively heavy 86. A twin screw supercharger on the stock 2 liter would probably perform better with just as much throttle response.

Probably my favourite engine sound of all time:

But the article, Where this is from, Claims that it's 30kg lighter, And a slightly improved the weight distribution.

Cool guy, awesome car, great sound.

If you like the sound of the 2.7, you're going to love this 3.0:

IMO I don't think there's a modern supercar that sounds as good as the Lexus LFA
