Much of the difference in automotive engine technology between the U.S. and Europe/Asia is due to taxation and other regulatory reasons. Vehicle tax in Europe has traditionally been based on engine displacement, so the European automakers have had to respond with high technology, small displacement engines to reach desired power levels. With no displacement limits and traditionally "cheap" fuel relative to Europe, U.S. manufacturers took the large displacement, low RPM approach to reach equivalent power levels.
Neither is necessarily better or worse than the other - they both got the job done in their respective marketplaces in their day. Globalization, emissions regulations, CAFE standards, etc. are moving technology toward the smaller displacement turbocharged engines we see today almost solely because they produce better numbers in government test cycles.
