blueefficiency

Ответ от Cheery[гуру]
это куча разных пассивных примочек, суммарно приводящих к уменьшению потребления топлива:
уменьшение веса машины (за счет более тонких стекол и звукопроницаемости корпуса) , аэродинамической формы (часть передней решетки прикрыта, выступы в зеркалах и ручках оптимизированы) и тд и тп. То есть измения есть, хоть и незаметные для непосвященных
In its Blue Efficiency line-up Mercedes employs what I like to call passive modifications. Rather than requiring the driver to do something to get better fuel economy, the efficiency is "built in." This means that even the most lead-footed of drivers will end up saving, whether they like it or not.
Most of the modifications were made to either the weight of the car or the car's aerodynamics. In the auto design world, these two items are usually considered low-hanging fruit. Beyond that, they're modifications that don't make the car slower and therefore are unlikely to dull the driving experience.
In the Blue Efficiency models Mercedes shaved weight with lighter windows, less sound-proofing, and a thinner windshield. To reduce aerodynamic drag the car was lowered, has part of the grill blocked, and had some protrusions like mirrors and door handles optimized. This all makes for a more efficient car that the public is likely not to notice.
