Everyone loves the sound of the Mustang GT’s rumbly exhaust, right? Well, we certainly do. But we have to confess that if it was rumbling outside our window and we were trying to sleep in, we’d be a little annoyed. [Editor’s note: My better half would be annoyed…I would try to identify the type of car without looking out the window: “Relax honey, it’s just our neighbor Jim taking his GT350 for an early morning spin.”]
In addition to burning the midnight oil crafting the new 2018 Mustang GT, Ford engineers have come up with a plan to help keep neighbors happy: the “Industry First Quiet Start” (aka “Good Neighbor Mode”).
Ford says the story goes like this: On a peaceful morning in his neighborhood, Steve von Foerster (above), former head of Ford Vehicle Engineering, had just backed a Shelby GT350 Mustang out of his driveway. An annoyed neighbor called the cops. He didn’t get a ticket, but he did get an idea for the new Mustang.
“I love the sound of the V8, but it can be loud, and you can’t annoy people like that in your neighborhood,” said von Foerster, who now leads Ford’s user experience team in product development. “It sounds so cool, but I thought, ‘There has to be a way to give people more control over the engine’s sound.’”
Von Foerster and Mustang program team members went on to develop Quiet Exhaust mode and Quiet Start, known as “Good Neighbor Mode” among Mustang engineers. The new features allow drivers to keep engine sound at a minimum if they wish and to program quiet start-up times in advance.
Using steering wheel-mounted controls, drivers toggle through a menu in the instrument cluster to select when they want to start their Mustang GT without sharing the event with neighbors. For example, between 8:00 pm and 8:00 am, drivers can schedule their car to start, without the roar.
Both new Quiet Exhaust mode and Quiet Start features will be part of the available active valve performance exhaust system on the new Mustang GT, along with different exhaust volumes for Normal, Sport and Track modes, giving drivers more choices.
“When sounds get up into the upper-70-decibel range, that’s typically about when they start to bother people,” said Matt Flis, Ford exhaust development engineer. “With quiet start activated, the decibel level of the new Mustang GT drops by about 10 decibels – about the level of a household dishwasher.”
Ford says active valve performance exhaust is one of many changes Mustang fans will see when cars reach showrooms later this year.
