OT: Which Engine Configuration has the Most Power?, Curious Minds Want to Know Options

[Britain Smith]

I was discussing the engine layout of a Porsche motor in a horizontially opposed configuration and the question came up on which engine configuration produced the most HP/liter and why? I know that an advantage of a Porsche motor is that the center of gravity is really low, but does its configuration have any power advantages when compared to say a 90 degree V6 or an straight 6? For simplicity, lets keep the discuss focused on normally aspirated motors. What are you thoughts and why?

[Rotary'14]

Concerning rotary engines, I feel that mazda has come a long way in regards to the refinement and evolution of the engine. Mazda's latest rotary engine uses an idea that has been around since the 70s (in regards to port design/layout) but efficient fuel control took 30 years to make the idea a reality. Remember the rotary engine is merely an adolesent compared to the piston engine designs that have had over a century of developement. I bet new coating technology would likely help the rotary engine in it's later developement.

On a side note my beloved rotary engine has attributes that make it a good candidate for a hydrogen IC engine. So the engine might be as common as the piston engine in a hydrogen powered future.


Don't get me wrong now, I do not want this to turn into a rotary is better than everything kinda thread.
I think piston engines are marvelous too, really!
