I found this extract in an article entitled "New 5 Series heads BMW changes for 2013"
on the BMW Group website:
"All 5 Series diesel models now benefit from either a NOx Storage Catalyst or an SCR catalytic converter with urea injection, which allows them to meet EU6 emissions targets more than a year ahead of the scheduled introduction"
Can anyone confirm whether the 535d available in SA has Urea injection?
I am looking for a new car and am debating the merits of the F10 535i vs the 535d. I will most likely buy a 2-3 year old car and have found a good example of a 2013 535d.
The diesel is more economical but diesels can release harmful emissions, NOx being one (hence the need for the Urea injection). The diesel releases less CO2 vs a petrol engine.
Extract of an article I read this morning about the petrol vs diesel debate:
"Diesel requires more crude oil per gallon. The end result is a fuel that boasts much greater energy density than gasoline, which explains why diesel cars get up to 40 percent more miles per gallon than their petrol counterparts. The higher energy density also means that burning a gallon of diesel emits more greenhouse gases than burning a gallon of gasoline—about 15 percent more, to be specific. But due to the appreciable fuel-economy savings, diesel cars usually emit less of these gases per mile driven.
There's a more disturbing difference between diesel and gasoline: Burning diesel also emits nasty particulates and smog-forming nitrogen oxides, as should be apparent to anyone who's ever gotten a mouthful of bus or tractor exhaust.
The good news is that today's diesel contains significantly less sulfur than in years past, resulting in much less harmful soot. On top of that, new diesel cars are outfitted with ingenious emissions-control systems such as BlueTec, which treats exhaust with a urea-based solution to reduce its toxicity."
