If you're a tech junkie (like me), you will enjoy seeing what was then the state of the art (automotively speaking) vs. now.

The epitome of piston engine development we see being revisited today, i.e., 4 valves/cylinder, fuel injection, water injection dual stage supercharging, cam phasing, etc was known at the end of WW-II - engines used in aircraft specifically. So, I find the "gee whiz" press releases and tech writers falling all over themselves to marvel at some of the automotive engine tech du jour as being so "cutting edge". Oh, please! But, I digress...

Interesting (YouTube) article anyway...
