The website Clean Green Cars has published complete tables of sales-weighted CO2 performance for all manufacturers, models and segments in the UK up to September 2007. While we already know the MINI is a pretty clean burner, independent verification is always nice.
>The best performance came from Mini which cut its average CO2 by 17.1% to 150.8g/km, partly due to the development of their highly efficient diesel engines. By 2008 Mini could have the lowest average CO2 output of any mainstream manufacturer.
