Infiniti is the luxury brand of the Nissan group.

You need to post 5 times before you can add links, as a means to avoid spambots.

Turbo charger with wastegate accomplishes same results with far fewer mechanical parts.

No, it goes further. And the turbocharger is part of the plan, the variable compression ratio can compensate for the pressure variance the turbo would cause.

See Variable Compression Engine - How Infiniti VC-T Works.

Sorry, but one, single, spinning turbine is a FAR fewer parts-count than all those mechanical items just for ONE cylinder.

Its a cool idea but it doesn't seem to be that more power full and not that much more fuel efficient then todays GDI turbo engines.

The rod angle is nice and will help with side load but I just don't see any major issues with todays engines when it comes to side load?

One is CHEAPER than many.
And usually way less efficient.
