Thanks for helping me back in there Bobby.

Interesting, I thought a V6 was imbalanced. It being 2 3 cylinder motors joined together.

The I4 has perfect primary balance (That surprised me).

I had a  3 litre V6 toyota motor years ago. Beautiful motor. Very smooth, revved freely.
Used more fuel, dearer to maintain.

Now I have a 2.4 litre I4 toyota. A bit less smooth at idle, once spinning it is very smooth.
They use a resin shaft in the counterbalance that negates the secondary vibrations.
Being a higher volume per cylinder may make it a less revving motor.

Cooling wise, the I4 is better.
In terms of using a motor more in its optimum working zone, the 2.4 is much better suited.

The 3 litre V6 was 'under' utilised far too much.
It would rarely be above 2000 rpm.

The 2.4 litre is usually around the 2000 rpm or much more.
Motors are happier spinning a bit rather than labouring at all.
