    Mclaren 570s , aventador sv, 918, Gallardo, ZR1, Laferrari, 720s spider, gt3, gt3rs, performante, ford gt, Senna, Scuderia, all louder then 458 italia.

    Every car we test goes through rigorous evaluations of its performance: the straight-line acceleration and braking, lateral grip, and fuel economy. We also measure the sound inside each car three times: once when stopped, idling; again at a steady 70-mph cruise; and—this is the most fun—with the gas pedal pressed to the floor. Since idle sound and highway driving are about as much fun as playing catch with a brick wall, let's focus in on the loudest test: that wide-open-throttle measurement.For all of our sound measurements, we use a precision instrument that measures the sound pressure level in the cabin.

    Why are we talking about pressure and not, you know, "loudness"? Because we're sticklers—and yes, that means you're actually using the term "loud" wrong. Loudness is how humans hear sounds, which is distinct from sound pressure, which is measured in decibels (dB). Anyway, do you want to see which cars we've tested that registered the highest decibels? Swipe through for a look at the list.

    2018 Porsche 911 GT3 Touring – 95 decibels (tie)
    Basically a wingless, more civilized 911 GT3, the 2018 Porsche 911 GT3 Touring opens our list with a wide-open-throttle sound level of 95 decibels, comparable to the sound a subway train makes from 200 feet away. These glorious decibels are blasted into the cabin by a 500-hp 4.0-liter flat-six that revs to 9000 rpm.

    2018 Porsche 911 GT2 RS Weissach – 95 decibels (tie)
    The most powerful production 911 to date is the 700-hp, track-ready 2018 Porsche 911 GT2 RS Weissach. Powered by a twin-turbocharged 3.8-liter flat-six that revs to 7000 rpm, the GT2 RS rips to 60 mph from a standstill in only 2.6 seconds, delivering 95 decibels of auditory assault at wide-open throttle.

    2018 McLaren 720S – 95 decibels (tie)
    With its gas pedal pressed to the floor, the 2018 McLaren 720S's twin-turbocharged 4.0-liter V-8 yelps out 95 decibels inside the snug cabin. Meanwhile, it's routing up to 710 horsepower and 568 lb-ft of torque to the rear wheels; that power is enough to make the McLaren one of the quickest rear-wheel-drive cars we've ever tested with a 2.7-second run to 60 mph and a quarter-mile pass of 10.2 seconds.

    2017 Ford Mustang Shelby GT350 – 95 decibels (tie)
    The 2017 Ford Mustang Shelby GT350 is the cheapest car on this list, with a then-base price of $57,045. It is propelled by Ford's hand-built Voodoo V-8, a naturally aspirated 5.2-liter flat-plane-crankshaft V-8 with 526 horsepower on tap and, at full throttle, a 95-decibel imitation of a Ferrari V-8's voice.

    2017 Chevrolet Corvette Grand Sport – 95 decibels (tie)
    With "only" 460 horsepower at its disposal, the 2017 Corvette Grand Sport is still capable of making quite the racket, which is exemplified by its peak sound level of 95 decibels. None of the reason it's so loud is due to the Z07 track package, which adds Michelin Sport Cup 2 tires, a more aggressive spoiler, and carbon-ceramic brake rotors. Those bits are just cool—and helpful on a track. It's the Corvette's available dual-mode exhaust that helps its 6.2-liter small-block V-8 sing at maximum volume.

    2017 Chevrolet Camaro ZL1 1LE – 95 decibels (tie)
    It is a little surprising that the 2017 Camaro ZL1 1LE's V-8 belts out the same 95 decibels at wide-open throttle as the '17 Corvette Grand Sport. The ZL1 gets GM's LT4 supercharged 6.2-liter V-8 and makes markedly more power. Oh well, we'll take our small-block rocks where we can get 'em. The track-special Camaro rockets from zero to 60 mph in 3.5 seconds and from a bevy of weight reductions all in the name of going fast around the track.

    2016 Porsche 911 R – 95 decibels (tie)
    Porsche's highly coveted and low production 2016 911 R gave brand aficionados plenty to freak out about, including a six-speed manual transmission, the 911 GT3 RS's suspension hardware, and the GT3's sweet 4.0-liter flat six—and less of that car's ostentatious bodywork. Not only does the 911 R look less conspicuous than a 911 GT3 RS, it's far quieter, producing "only" 95 decibels at WOT; the RS's decibel readings are far, far higher.

    2015 Lamborghini Huracán – 95 decibels (tie)
    Introduced for the 2015 model year, the Lamborghini Huracán is the Italian brand's "entry-level" supercar. You probably wouldn't think to use that descriptor given the baby Lambo's performance: It hits 60 mph in 2.5 seconds, and its enthusiastic 602-hp 5.2-liter V-10 shouts out 95 decibels from its perch just behind the front seats.

    2015 Chevrolet Corvette Z06 – 95 decibels (tie)
    The 2015 Chevrolet Corvette Z06 is another one of GM's fire-breathing monsters. It's motivated by the wondrously powerful 650-hp LT4 engine, so it's not terribly surprising that the engine delivers the same 95 decibels to the Z06's occupants as it does in the Camaro ZL1. The Z06 is good at more than just creating noise; assisted by the Z07 track-handling package, it pulls 1.19 g's on the skidpad and can absolutely devour a racetrack.

    2011 Ferrari 458 Italia – 95 decibels (tie)
    Everything about the Ferrari 458 Italia is sharp. The steering is superprecise, the seven-speed dual-clutch automatic gearbox shifts ultraquickly, and beneath that sultry bodywork sits an absolute screamer of an engine that barks out an edgy staccato capable of rising to 95 decibels. That V-8, by the way, is a high-water mark—at least in terms of sound: the 458 Italia was replaced by the twin-turbocharged 488 GTB, whose engine sound seemed muffled by the forced-induction setup. The 488 has since been replaced by the also-turbocharged F8 Tributo, but Ferrari claims to have brought back some of the 458's aural magic.

    2006 Saleen S7 Twin Turbo – 96 decibels
    The 2006 Saleen S7 Twin Turbo is the brainchild of famed Mustang tuner Steve Saleen. This wild all-American, 750-hp mid-engined race car for the street was created in Irvine, California, and is the oldest entry here. Hey, it can make noise as good as that of the younger whippersnappers that fill the rest of this list.

    2016 McLaren 570S – 97 decibels (tie)
    A destroyer of corners and slayer of back roads, the 2016 McLaren 570S has a twin-turbocharged 3.8-liter V-8 capable of revving to 8100 rpm. Although McLaren considers this machine to be among its lower-level offerings (the 570S is a member of the brand's Sport Series, which is bested by the Super and Ultimate series), it sure doesn't croon like some "base" car—after all, there's nothing basic about 97 decibels.

    2016 Lamborghini Aventador LP750 SV – 97 decibels (tie)
    The brash and bold 2016 Lamborghini Aventador LP750 SV is blessed with the largest engine on this list, a naturally aspirated 6.5-liter V-12, yet doesn't make the biggest sound on this list. Still, you try a 97-decibel full-throttle rip in the big Lambo and tell us you think anything about the experience counts as "small." The SV's advantage over lesser Aventadors comes thanks to a freer-flowing exhaust and a higher engine redline of 8500 rpm.

    2015 Porsche 918 Spyder – 97 decibels (tie)
    When most people think of a hybrid, plug-in or otherwise, they think of something slow and bland—like a Prius. Porsche's 918 Spyder is neither of those things, even if it is a plug-in hybrid. This ridiculous, 887-hp supercar remains a standout even today—it first went on sale in 2014 and has since been discontinued—and its gas engine and electric motors can stir up a very un-Prius-like 97 decibels.

    2009 Lamborghini Gallardo LP560-4 – 97 decibels (tie)
    For a car with a mouthful of a name, the 2009 Lamborghini Gallardo LP560-4 sure doesn't talk like it has its mouth full. The precursor to today's Huracán, the Gallardo was calm and collected at speed yet capable of whipping its longitudinally mounted, naturally aspirated V-10 engine into a 97-decibel frenzy.

    15 of 26
    2008 Chevrolet Corvette ZR1 – 97 decibels (tie)
    The 2008 Chevrolet Corvette ZR1 was a cruise missile, unlike today's more knife-edged, track-friendly ZR1. It was a raw Vette with huge horsepower, and it was capable of giving anyone who drove it an unparalleled adrenaline rush and a 97-decibel ear thwacking, thanks to its absurdly powerful, supercharged 6.2-liter V-8 LS9 engine.

    2015 Ferrari LaFerrari – 98 decibels
    Ferrari's entry into the hybrid-hypercar wars was the $1.4 million 2015 Ferrari LaFerrari. When we sneaked in a test of the redundantly named Ferrari, its 6.3-liter V-12 easily outscreamed the electric motor and pushed our sound reading at full throttle to 98 decibels.

    2019 McLaren 720S Spider – 99 decibels (tie)
    Just like its hardtop sibling, the 2019 McLaren 720S Spider is a breathtakingly beautiful machine that turns heads as well as it turns lap times. It is, however, louder than the fixed-roof 720S; its folding-hardtop roof lets in more noise from the twin-turbo V-8, showering occupants with 99 decibels. Noise aside, the 720S Spider performs just as well as the coupe at the track.

    2019 Chevrolet Corvette ZR1 – 99 decibels (tie)
    The loudest front-engined car on this list won't be front-engined for much longer. (Get it? Because the Corvette is going mid-engined.) Anyway, the latest and greatest front-engined Vette is the 2019 ZR1. It (and its 755-hp supercharged V-8) is a 99-decibel swan song for the engine layout Chevrolet has relied upon since 1953 for its all-American sports car.

    2018 Porsche 911 GT3 – 100 decibels (tie)
    It's only marginally disappointing that Porsche buries the epic 4.0-liter flat-six that powers the 2018 911 GT3 deep in that car's tail, under a tiny trunklid and an innocuous plastic fan shroud. Hey, at least using your senses other than sight to experience the engine is easy. Simply step on the gas and prepare to be assaulted by 100 decibels of race-car-like noise. That isn't the only motorsports connection: the GT3 is assembled in the Porsche Motorsport race-car factory in Flacht, Germany.

    2018 Lamborghini Huracán Performante – 100 decibels (tie)
    In taking its fantastic Huracán and adding some more power, spicier aerodynamic bits, and better tires while cutting weight, Lamborghini created the 2018 Huracán Performante. You're welcome, world. Just looking at the thing, it probably isn't surprising that this raging bull snorts 100 decibels into its driver's ears at full chat.

    21 of 26
    2017 Ford GT – 100 decibels (tie)
    It's no surprise that the 2017 Ford GT looks, drives, and sounds like a race car. It was, after all, developed at the same time as the Ford GT that won its class at the Le Mans 24-hour endurance race in 2016. Its twin-turbocharged 3.5-liter V-6 is noisier than most other forced-induction engines, pumping out 100 decibels at full throttle. It also pumps out 647 horsepower and 550 lb-ft of torque, enough to (briefly) make the GT the quickest car ever to lap Virginia International Raceway in our hands. Its crown was later stolen, but still.

    2019 Porsche 911 GT3 RS – 102 decibels (tie)
    In creating the 2019 911 GT3 RS, we're glad nobody at Porsche stopped to ask if having a flat-six engine capable of spinning to an insane 9000-rpm redline and delivering 102 decibels was legally okay. Of course, we assume the car passed the U.S. market's necessary drive-by noise regulations—but those tests aren't conducted at full throttle. Truly our only complaint about the GT3 RS is that this everyday, street-legal race car is somewhat quieter than it used to be. A 2016 model registered even more decibels.

    23 of 26
    2019 McLaren Senna – 102 decibels (tie)
    The 2019 McLaren Senna has a powerful twin-turbocharged V-8 engine, lots of racy aerodynamic features, and launches from a standstill harder than you can say "from zero to 60, and beyond!" It also pumps Saturn V rocket levels of eardrum-shattering noise into its cabin at wide-open throttle, cranking our decibel meter to 102.

    24 of 26
    2009 Ferrari 430 Scuderia – 104 decibels
    In creating the hard-core, track-ready 2009 430 Scuderia, Ferrari removed the sound deadening material from the regular F430 and turned up the wick on its 4.3-liter V-8. In our testing, that series of excellent decisions resulted in 104 decibels of glorious noise while the V-8 chased its 8500-rpm redline. Without the pesky sound deadening, you're free to enjoy every vibration—or suffer hearing damage.

    25 of 26
    2016 Porsche 911 GT3 RS – 108 decibels
    The 2016 Porsche 911 GT3 RS is a beauty. Whether you find carving apexes to be attractive or are tickled by a thing's actual looks, the RS checks the right boxes. Aurally, it's in a different league. At idle, the Porsche makes a discordant cacophony of sounds, but with its gas pedal smashed to the floor, we measured an earplug-worthy 108 decibels inside the car. Seriously, the RS's 4.0-liter flat-six as it approaches its 8800-rpm redline is not something to be trifled with, and it's definitely something you want to experience in person.

    Personally, I always take these articles with a pinch of salt.

    Like most things in life, there are excellent professionals and bad professionals. Some journalists have driven more cars than I own trousers, have even bought some of the cars they’re reviewing and lived with them as opposed to spending an afternoon in it, have an intense passion about what they do and always go the extra mile: read more, dig up old articles and review them in a different light, contact former drivers and engineers and, more importantly, express their view based on experience and facts, with absolute independence.

    Others, I’m sad to say, are paid to write whatever their master tells them to.

    It’s hard to distinguish sometimes one from the other, although given enough time, it becomes crystal clear.

    My point being: when it comes to the sound department, loud doesn’t necessarily mean quality or good. My neighbor’s grandmother can shout louder, but she’s no Pavarotti.

    Well... for what it’s worth, it is the ONLY mainstream Ferrari on the list, a 26 car list with just 2 other Ferraris, one of which is a 1.000.000 plus car. :)

    Should we make fun about the 458 being on that list, or the fact that the 488 isn’t in any variant? :)

    Ha , ha. I knew you were going to respond -:). Yes, magazine/reviews of performance and driving characteristics I'd tend to agree with you.

    There's no subjectivity with measuring in car sound at wide open throttle.

    Exterior sound = Enjoyment for people standing around outside the car
    Interior sound = Enjoyment for people inside the car (which to me is the more important type of sound).

    I've owned and driven at WOT - gt3rs, 720s, scuderia, 458. I've been inside Laferrari, performante as a passenger at WOT.

    I tend to agree with the list (it's not subjective anyways).

    As an owner I’ll tell you this....the Performante spyder is by far the loudest I’ve been in for my ears. 458 the most pleasing sound.
    I have not been in a tdf yet sadly. I found the 918 to be fairly loud.
    Aventador svj 63 maybe highest ear splitter.
