It’s called Quiet Start and it’ll keep you friends with the neighbors
Ford Mustang’s “Good Neighbour Mode,” or Quiet Start, is a feature that allows you to tone down your vehicle’s exhaust loudness in order to avoid disturbing others.
In a Ranker.com survey, loud engine revving is one of the most annoying noises in a quiet neighborhood. Although an American V8 sounds glorious compared to a lawnmower (which, by the way, is THE most hated noise you can hear in the morning) it can still bug people’s ears if they’re not part of the action.
In order to make the Quiet Start and Quiet Exhaust even more easy to accommodate in a Mustang owner’s life, Ford allows both features to be scheduled.
“Sounds upwards of 80 decibels can start to irritate people; some of the most annoying sounds imaginable, such as a coffee grinder, or lawnmower, have decibel levels in the high eighties,” explained Ford exhaust development engineer Matt Flis. “With Quiet Start activated the decibel level of the new Mustang GT drops by about 10 decibels, to a much more comfortable 72 decibels.”
Considering the Mustang’s sales following its European debut, in early 2015, the American muscle is an absolute success: almost 30,000 units have been sold since then.
