To the best of my knowledge, the same but it really takes friends overseas to check. For example, the North American NHW11 has a hydrocarbon converter not found overseas. However, they had an optional fold-down rear seat. The North American NHW20 has a thermos for hot coolant that is missing in the EU and Japanese NHW20s. Apparently the ZVW30 can have a 'heads up' display that is not available in North America. But the fundamental vehicles and drive trains are the same.

Now the EU and Japanese mileage testing protocols are different from ours and more different after the EPA 'adjusted' them in 2008. So even after adjusting for gasoline units, the respective government tests are different and ours are more conservative. Funny, the modified EPA tests have not really impacted the actual mileage. <wink>

Go to Fuel Economy and compare the EPA numbers versus user mileage for:
  • 50(EPA) vs 48.8(139 vehicles) - 2010 Prius
  • 41(EPA) vs 49.1(16 vehicles) - 2010 Insight
  • 34(EPA) vs 44.8(13 vehicles) - 2010 Jetta TDI
So the 2008 'adjustment' fixed the Prius numbers but the Honda Insight and Jetta TDI still look bad. What is really sad is what happened to the NHW11 Prius:
  • 48(old EPA) vs 41(new EPA) vs 45.4(24 vehicles) - 2003 Prius
The EPA error has flipped to the other side.
