The Lexus 8 speed automatic

Can someone please explain why a car needs a damn 8 SPEED?

more moving parts that can break in my book........

but maybe one of you experts can explain the advantages to 8 gears.

People say that everytime a new trans comes out. The 5,6,7 and now 8.

If you look at it your way we would still be driving cars with 1960's technology.

The more gears a trans has, the narrower the power band on the engine needs to be. That is why semi's have 13 speeds, the engines have a low redline but high torque, more gears keeps them in the optimal range. That was the theory behind the CVT, let the engine speed stay the same, and change the gear ratio.
