Thermodynamics. Energy in/energy out, the challenge is making it come out as torque instead of heat.

 

There may be super efficient motors, in terms of fuel conversion to torque, but are they efficient in economic terms?

There's the market aspect.

 

mass production can overcome these cost problems, but it takes time. The world manufacturing infrastructure is tooled up for making cost effective traditional ICEs. The off-brand ecosystem which services the production of these engines is part of the mix. It wall works together to deliver remarkably reliable products at affordable prices.

One way to increase fuel efficiency and overall cost, is reduce the weight and speed of the vehicle. But people don't want that. And the world fleet of used vehicles can be kept going indefinitely, unless legislation forcibly retires it.

Always thought  that it would be best enviromentally to retrofit rather than replace but it seems to not make economic sense versus new.

It's a great idea. A common powerplant unit, super efficient but mass producible due to being a single model. Every car gets the same engine, no arguments. A one off, properly engineered (probably by Toyota), built for low down pulling power, not speed, with as many standard parts as possible. Built for repairability.

 

The powerplant will be supplied with a cradle appropriate to your vehicle engine bay.
