It is the engine sound at the end.
Engine sound is the basis of sound emanating from the car.
Although I think that there are that you have heard,
I think you've never heard engine sound turned with the foot on the accelerator with all one's might.
This is the sound of the naturally aspirated engine that was introduced at the bottom of the supercharger.
That is they're in the sound of the engine itself without unmixed.
This sound will excite the car you like.
I think people are excited to be non-car enthusiasts.
In addition, the engine sound is different sound from low to high sound.
Although you'll see if you can look at a diagram of the reciprocating engine, which was introduced in about the engine,
There is a length of up-and-down motion.
Higher the shorter the length, the value is lower if long.
The high pitch is easy out since the time of the up-and-down motion, so reduced as short, it is possible to obtain a high number of revolutions immediately.
To narrow the location of the up-and-down motion to short, high-pitched sound that is comes out the car air quantity entering the engine inside a multi-cylinder is small.
As a typical example, there is a car that Lexus LFA.
The longer the time of the up-and-down motion, time will take speed is to go up,
torque is the force pushing, the car will grow thicker.
Something American-produced automobiles and trucks are so.
To widen the location of the up-and-down motion to long, that is thick low sound comes out the car air quantity entering the engine inside a multi-cylinder in many cases.
When you issue the example of sports car, there is a car that Aston Martin one-77.
I have a different sounds in the same engine.
It is not possible to even consider the environment, and discard the engine again.
We went to the conclusion that we allowed the turbo charger in hybrid vehicles.
