Thanks Paintboy - you have brought us back to earth! While much less interesting and fun than contemplating the world order if the Germans had the 2.5 in WWII, I just checked the EPA site re: the fuel economy numbers for the 1999 2.5 versus the 2000 2.7:

1999 Boxster 2.5 manual: 17 MPG city, 24 MPG HIghway, 20 MPG combined
2000 Boxster 2.7 manual: 17 MPG city, 25 MPG Highway, 20 MPG combined

Wow, if Porsche changed the gearing on the 2.7 for the purpose of improved fuel economy, they failed dismally! The combined number is identical and the 1 MPG improvement on the highway cycle could probably be explained by anything from varainces in individual cars to the improved fuel injectioin system. Even worse, while trying to improve fuel economy at the expense of performance, they actually by their own admission in the brochures (and as confirmed by contemporary tests) IMPROVED performance. Porsche got it all wrong!
