wrong. the people who actually pioneered the whole overhead twin-cam and 4 valves per cylinder engines, are bentley. and they did it back in the 1920's. (sounds a bit far-fetched, i know, but feel free to look it up) so to correct your statement: there'd be no 16v twin cam engines if it weren't for those crazy brits. and on a side note, they (well, not exactly bentley, but some of the ye-olde 'bentley boys') also pretty much pioneered the concept of forced induction engines. feel free to look that up as well.
