More hybrid bashing: "MINI D emits less CO2 than hybrids"

BMW-owned MINI recently commissioned YouGov PLC to conduct a survey on alternative fuels and technologies in Britain. It turns that few respondents were aware that some diesel-powered cars actually had lower CO2 emissions than the hybrids currently on the market. Of the cars included in the list (Honda Civic Hybrid, Toyota Prius, MINI Cooper D, Ford Focus 1.6 Duratorq TDCi and Citroen C4 1.6 HDi), most people thought the Civic Hybrid had the lowest emissions. In fact the MINI D was lowest at 104g/km equal to the Prius and ahead of the Civic's 109g/km.

Umm... ok. I guess. How can BMW claim that the Mini "had lower CO2 emissions than the hybrids currently on the market" when it turns out that the Prius has the same lower CO2 emissions level?

And why would one compare the Mini (a sub-compact) to the Prius (midsize) or the Civic (compact)?
