At the time of thinking how to improve fuel efficiency we go thinking for motor size reduction, alternative fuels or electricity but it does not normally come to our minds noise cancelling technologies. While the noises that a car makes do not have to do directly with fuel efficiency they are important because often times it is a determinant factor to know if a certain powertrain solution is acceptable to driver and passengers. Sam Abuelsamid from AutoBlog tells us new ways to improve developments without making too much noise.

Companies among BMW, Honda or GM are actively developing ways to control noise at the source in order to make room for powertrain improvements. A good sample is the 2010 Chevrolet Equinox: GM incorporated active noise cancellation so it could let the engine to spend more time running at lesser speeds where the engine tends to make more of a low booming sound. Without the noise cancellation technology, the noise would turn off drivers.

BMW has been carefully after structures of engine blocks or bays. The application of ribs and tuning of structural shapes had made lighter structures without the risk of excessive vibration helped by special insulation materials.

All of these aspects show into making more efficient vehicles that are attractive to consumers. After all, if consumers don’t want to buy a vehicle for reasons that have nothing to do with function, all of the efficiency rewards they might offer will be left stuck in ‘park.’
