If you can afford a Ferrari, you let someone else worry about that!..............

Great potential for improved combustion efficiency.

Hemispherical combustion chamber was invented for that reason don’t believe Ferrari will gain much if any ground over that.

I recall those engines had some cooling issues and were short-lived. ‘90’s was a great period in bike racing.

If the add TWO sparkplugs per cylinder, one on each end you could get more complete combustion!..............I

For as long as internal combustion engines have existed, pistons have been round.

False. Cylinder bores have been round. Pistons are slightly elliptical to accommodate thermal expansion.

The benefits of oval pistons are potentially more than just space-saving. Depending upon how the oval shape is implemented, there is great potential for improved combustion efficiency, lower frictional losses, and better thermal management


granted there is space savings. the other things are potentials to attract investors.

complexity is a problem in it self. Lots of innovation in the past but simplicity seems to win.

but it is good to explore.
