Dear forum, does any of you know if and when other engines than the current V6 M276 come with the lean technology? Next maybe the 400 BE with M276 Turbo? The new four-cylinders in the B-Class are obviously not lean, does that come with the announced 2-litre? And wouldn’t the V8 have to come with the technology at some point in theory, or does it already? Or does it prefer cylinder formwork like AMG and Audi? I ask because Audi with the A4/A5 has now presented quite a bit with 5.7l/100km, the C 200 currently needs exactly one litre more (and by the way, the A4 accelerates even faster). In the new 3 Series there are no techs. Data from the 320i. And the 350s are today very superior in consumption, i.e. one would have already finished the technology. Many greetings and beautiful Christmas!
