Mustang sound: the 5.0 Mustang GT
The Ford Mustang GT sounds the way most people expect a Mustang to sound, with a deep, uneven burble at idle that hardens into a loud, rising growl, because its 5.0-liter Coyote V8 uses a cross-plane crankshaft. This page covers the 2018–2023 car, whose third-generation Coyote makes 460 hp and revs to 7,500 rpm, with start, idle, rev and drive recordings from the Car Sounds app.
What to listen for
- Start: a strong flare of revs on crank-up, then the engine settling into its fast idle.
- Idle: the uneven, loping rhythm of a cross-plane V8, the clearest example of the classic Mustang sound.
- Revs: how the deep growl gains a harder, raspier edge as the engine climbs toward 7,500 rpm.
- Drive: the low-rpm rumble under load and the pitch rising steadily through each gear.
Why the Coyote burbles
A cross-plane crank spaces its crankpins 90 degrees apart. That keeps the engine smooth, but it means each bank of four cylinders fires at uneven intervals. The exhaust on each side receives those pulses unevenly, and that irregular rhythm is the lumpy, off-beat sound at idle that defines the classic American V8.
At idle and low rpm that unevenness reads as a lazy wobble you can hear from the tailpipes. Under load the pulses arrive so quickly that they blur together into a thick, continuous growl.
A 5.0 that likes to rev
The Coyote is not an old-school pushrod engine. It has four valves per cylinder and dual overhead cams on each bank, and the third-generation version combines port and direct fuel injection. Peak power arrives at 7,000 rpm, and the engine keeps pulling toward its 7,500 rpm limit.
That gives the Mustang GT a wider range of sounds than its big-displacement rivals. The bottom end is all rumble, the midrange adds a harder edge, and near the top you start to hear more intake and valvetrain noise layered over the exhaust. The firing frequency shown above explains why the pitch climbs so noticeably on the way up.
Active exhaust and quiet start
Many 2018–2023 Mustang GTs have Ford's optional active valve performance exhaust, which uses valves to change how loud the car is, with selectable modes ranging from quiet to track. A Good Neighbor Mode can also schedule quiet cold starts for early mornings. That is why two Mustang GTs can sound quite different on a cold start: one with the valves open, one deliberately muted.
Frequently asked questions
What engine gives the Mustang GT its sound?
The 2018–2023 Mustang GT uses Ford's 5.0-liter Coyote V8, a naturally aspirated, dual-overhead-cam engine with a cross-plane crankshaft that makes 460 hp and revs to 7,500 rpm.
Why does the Mustang GT sound different from the Shelby GT350?
The Mustang GT has a cross-plane crank, which gives the uneven burble of a classic V8. The GT350's 5.2-liter Voodoo uses a flat-plane crank, so it sounds smoother at idle and much raspier at high rpm.
What is Good Neighbor Mode on the Mustang?
It is a setting available with the active valve exhaust that keeps the exhaust in its quietest mode during a time window you choose, so early-morning starts are not as loud.
