This is one of those "only in China" stories.
In my last post, I mentioned how surprised I was to see an "欧V" label on the back of a tour bus in Beijing:
欧V universally means Euro V tailpipe emission standard; the strong implication here is that this vehicle meets that very strict standard. Similarly, here is a label on a (different brand) bus showing that it meets Euro IV (欧IV, the current standard in Beijing) emission standard:
However, I just learned from my colleague that the "欧V" label on the white bus does not have anything to do with tailpipe emission standard. Rather, the bus model is simply called 欧V, with the V meaning the letter "V," not the roman numeral for 5. The website for the bus, made by Foton, is here. In English they call it model AUV:
Although it appears that the bus is available in some alternative energy configurations like hybrid - which is commendable for many reasons - even the hybrid apparently only meets the Euro IV tailpipe emission standard: 污染物排放再[sic]欧III基础上减少30%，达到欧IV同等水平 (pollutant emissions are 30% lower than the Euro III level, meeting Euro IV equivalent).
Hmm. A bus called 欧V than only meets the 欧IV emission standard? Sounds like shanzhai to me.
