Car/engine shake when releasing the clutch pedal

[Kioshi]

Either the Yaris needs to be at a 100,000 miles + or something because my friends BMW 3 series doesnt do it and i thas 192,000 miles on it.
Its just not receiving enough gas. It works the same way in reverse too, try it. I use the reverse shaking one to pull out from the garage because I have blind spot on not seeing the car turning the corner.

Keep in mind that the 3xxi has a lot more torque than the Yaris, so the engine is less likely to stall as you let the clutch up.

The shudder is caused by the stationary clutch plate touching the engines flywheel. Obviously one has to stop or the other must turn. Therefore, the engine slows a little as it tries to move the clutch plate and when it drops below an acceptable idle it shakes. You can do this in any car if you let the clutch up at the right speed. Just take it as the car saying "you are about to stall me".
