BMW Alpina B5 F10 Bi-Turbo photos break out early

"get the same results"? You clearly have never driven an Alpina! ;-)

Although a petrol engine might emit more CO2, a diesel engine emits far more bad 'stuff' (e.g. fine particles) that actually makes you cough and directly cause asthma and cancer. CO2 is not directly harmful for humans, only indirectly (greenhouse effect and all that). Also from one barrel of crude oil one can produces far less diesel then petrol. So although a diesel engine might get a lower mpg rating, it will still effectively use up more crude oil then a petrol engine does! The diesel lobby (in Europe) is trying to push diesel as the more environmentally and economical option, which is blatantly untrue, as it is just a tactic to justify taxing diesel less then petrol. Which comes down to taxing the public more then businesses, which is of course completely unfair, especially since it's based on lies.
