The original Type 916 engine was apparently developed as a 2-liter 4-cam race motor and fitted in a 910 prototype, but was abandoned in the testing phase due to rule changes that favored development of the 8-cylinder 3.0 liter engine, and later the 12-cylinder for the 917. A group of engineers in Germany used the original specs for the 916 to develop a "916 Reloaded" 2.5 liter version at a "boutique engineering workshop in southern Germany close to Stuttgart," and the 5th iteration of this new engine has been installed in my old '68. Matthias calls it a "911RR" now.

I would love to have a chance to drive it again with this new powerplant. It was a hoot to drive with a Euro 3.0 of only 204 HP, so an extra 60 HP and 2000 more RPM before redline would make it even more lively, I'm sure!
