The powertrain of this Genesis SUV has a number of tricks up its sleeve

Luxury cars have always walked a fine line between silence and thrill. For decades, the rule was simple: the quieter the ride, the more luxurious the experience. But Genesis, Hyundai’s luxury offshoot, decided that’s no longer the only way to do luxury. A bold and athletic take on the brand’s flagship SUV, the new Genesis GV80 Coupe wants to make you feel something. Beneath the elegant sheetmetal are two pieces of engineering wizardry that show Genesis is cool in the pursuit of performance: something called an e-Supercharger and a new system called ESEV, short for Engine Sound by Engine Vibration.

It’s not often that a luxury SUV’s party trick involves reinventing what an engine sounds like, but the GV80 Coupe isn’t your standard family wagon. This is the first SUV in the Genesis range to combine the brand’s calm, stately appearance with performance technology that actively enhances the driver’s emotions. The idea is simple but clever: you can’t really enjoy performance if you don’t feel like we as drivers are part of it. Genesis wants to close that gap – not by putting fake sound through the speakers, but by translating real mechanical feedback into sound you can feel and believe.

To provide the most accurate and up-to-date information, this article uses data sourced from various manufacturers and authoritative sources.

The e-Supercharger: instant gratification

Let’s start with the hardware. The 2025 GV80 CoupeThe e-Supercharger is a small but powerful electric compressor that pressurizes the intake system before the turbochargers are even spooled up. Think of it as a head start for your boost – a magic bullet straight to the heart of turbo lag. Traditional turbos rely on exhaust gases for spooling, meaning there is some time between throttle and boost depending on the system. We call this car-killer “turbolag”. The e-Supercharger fills that gap, delivering near-instant throttle response and smoother, more linear power delivery.

Genesis borrowed this technology from its 3.5-liter twin-turbo V6, giving the SUV a sharp, confident feel when you put your foot down. The electric compressor is powered by the 48-volt mild-hybrid system, meaning it can kick in even at low speeds or while cruising. The result is seamless acceleration: no waiting, no hesitation, just smooth torque and controlled thrust. Ooh! Direct connection? Is that the sound of EV evangelists tightening their seats?

That’s important because the GV80 Coupé isn’t trying to be a hooligan. It’s a luxury SUV with the manners of a grand tourer. The e-Supercharger makes it feel effortlessly fast rather than brutal, retaining the refined character Genesis is known for and giving drivers a satisfying, instantaneous punch when merging or overtaking. Our own John Beltz Snyder said this about the E-Supercharger’s power delivery:

…it is also well mapped. This provides instant but smooth power – super linear as the twin turbos pick up where the e-Supercharger leaves off. A solid eight-speed gearbox ensures a drama-free transition through the gears.

ESEV: turning vibrations into music

Then there’s the real headline act: ESEV, or Engine Sound by Engine Vibration. At first glance, it sounds like another version of fake engine noise, something enthusiasts dutifully mock. But Genesis’ approach is much more sophisticated. Instead of using cheap, pre-recorded sounds, as many car manufacturers do, ESEV uses real-time data from vibration sensors mounted on the engine itself. These sensors measure power pulses and mechanical harmonics and then feed that data into an algorithm that translates it into sound: sound that corresponds exactly to what the engine is doing. Driving the GV80 Coupe, Snyder was once again shocked by how little he disliked this new generation of sound, given his obligatory skepticism of such technology.

I turned the sound off, which made the GV80 feel more like the quiet luxury experience we normally get from premium SUVs. I turned it back on because it not only sounds great, but also provides accurate audio feedback about what’s going on under the hood, making for a more engaging drive.

That means no awkward delays, no mismatched tones, and no artificial “revving” while nothing is actually happening. There is also a mental connection that keeps you in it. The system operates with a control loop of just 23 milliseconds, faster than the human ear can detect, creating a natural sense of connection between operator and machine. The vibrations you feel through the steering wheel, pedals and seat are perfectly in sync with what you hear through the cabin.

Amplify what is already there for more emotion

Senior Genesis engineer Dongchul Lee explained it best: “While ASS [Acoustic Sound Design] independently generates virtual sounds, ESEV goes one step further and takes into account the physical properties of the engine, such as vibrations, to create sounds that perfectly match driving performance.” In plain English: it’s not a sound effect. They are the real events of the engine, translated and refined.

A symphony, not a scream

The goal of ESEV is not just to make noise. Genesis has spent years fine-tuning this system to create a sound that feels as refined and sporty as it sounds. Engineers from Hyundai’s eP Acoustics & Vibration Research Lab studied the way the human ear perceives timing, pitch and mechanical feedback. They found that even a delay of 0.03 seconds can make a sound feel ‘off’. So they built a system quickly enough to trick your brain into thinking you’re hearing pure motor response, even if part of it is digitally enhanced.

That’s a big problem because modern engines, especially turbocharged and hybrid engines, can feel muffled. Sound plays a major role in the way we perceive speed and force. Genesis didn’t just want to turn up the volume; it wanted to restore emotion. The sound you hear in the GV80 Coupé is tuned to change dynamically with throttle and gear changes, emphasizing the rhythm of the drive without ever feeling artificial.

During initial testing, the system debuted in the Genesis G90 sedan, where it produced a smoother, more luxurious sound. But in the GV80 Coupé, ESEV’s sound profile is livelier: deeper, sportier and designed to make the SUV feel more alive without compromising serenity. It’s a balance that few brands manage to achieve, but Genesis seems to have found a sweet spot between authenticity and polish.

The luxury of feeling something

There is a certain irony in the GV80 Coupé’s approach to emotion. For years, luxury cars have tried to isolate the driver from the experience: quieter cabins, softer suspensions, thicker glass. Genesis does not abandon that comfort; it redefines it. The GV80 Coupé wants to give you the best of both worlds: peace while cruising, character while carving through bends.

Both the e-Supercharger and ESEV contribute to that feeling. One improves how the SUV responds, the other improves how it sounds. Together they create a sense of immediacy: a dialogue between machine and driver that most modern vehicles have lost. It’s not about volume or theater; it’s about coherence. When you accelerate, everything – the torque, the tone, the vibration – happens in perfect synchronization.

That harmony is the real trick of the GV80 Coupé. Genesis isn’t chasing old-fashioned muscular or electric minimalism. It walks a middle path: a high-tech luxury experience that still feels human.

A glimpse of the future

As electric vehicles continue to dominate the conversation, technologies like ESEV indicate where brands like Genesis could be headed. In an EV world, sound design becomes part of the emotional equation. Genesis engineers have said they see ESEV as a stepping stone – one that bridges the combustion emotion with the coming era of electrification.

If that’s the case, the GV80 Coupe might be more than just a stylish new SUV. It could be a blueprint for how luxury cars will make us feel connected again.
