The 2018 Ford Mustang GT will have a stealth mode to calm the engine's sound, an idea that came about as the result of a noise complaint from a neighbor.
The neighbor called the police one morning after the engine of a Shelby GT350 Mustang, owned by former Ford vehicle engineering chief Steve von Foerster, woke the neighbors in a neighborhood located in the Detroit suburbs, according to USA Today.
Ford will call the new feature "Good Neighbor Mode," and it actually has a setting specifically for "quiet starts." The Mustang also will have a quiet exhaust mode.
According to a study by Ranker.com, "loud engine revving ranks among the most annoying noises neighbors make, alongside other common nuisances including lawn mowers, power tools, barking dogs and band practice.”
The stealth mode features come at a price, however: an extra $895 for the active valve performance exhaust option package that will be available in all 2018 Mustang GTs.
“Active valve performance exhaust gives Mustang owners the best of both worlds — that classic Mustang sound, and the ability to not wake up your neighbors when you leave the house early in the morning or arrive home late at night,” Ford exhaust development engineer Matt Flis said, Auto Week reported.
“When sounds get up into the upper-70-decibel range, that’s typically about when they start to bother people,” Flis added. "With quiet start activated, the decibel level of the new Mustang GT drops by about 10 decibels, to a much more comfortable 72 decibels — about the level of a household dishwasher.”
The new Ford Mustang and its stealth mode will be available to drivers by the fall.
