THE SECRET BEHIND THOR

ONE or TWO Thor speakers,
optionally with the Thor ECHO system, are mounted underneath the vehicle.
An electronic control unit (module) is installed inside the vehicle.
THOR reads the accelerator pedal position and engine speed to deliver a perfectly synchronized sound experience.

Frequently asked questions

Thor is compatible with the majority of petrol, diesel, hybrid and electric vehicles equipped with a CAN-Bus, which means nearly all vehicles produced since 2005. Please just make sure there is enough space under your vehicle to mount the speakers.

Yes, completely. The Thor system can be removed without any damage to your vehicle and can be reinstalled on another compatible vehicle if you change cars.

It is technically possible if you have skills in automotive electronics and the right tools. To benefit from the full warranty, we recommend installation by a professional, one of our European partners or directly at Thor Tuning Belgium.

The Thor system is an additional sound device that alters neither the exhaust nor the original components of your vehicle. In most cases, no specific approval is required. We recommend, however, that you check the regulations in force in your country and switch it off during any technical inspection.

The audibility of the sound inside the cabin varies depending on the vehicle model, its sound insulation and the speaker installation position. For an enhanced sound experience that is clearly audible from inside your vehicle, we recommend adding the Thor Echo to amplify the sound up to 2X and/or opting for Level 3 or Level 4.

You manage everything from the Thor app (iOS/Android): sound selection, volume, activation/deactivation. You can also link a specific sound to a driving mode, or use the vehicle's standard buttons to switch between profiles.

Ford Mustang 2.3 EcoBoost: giving the world's most iconic four-cylinder turbo the sound of a V8 with a Thor Level 4 + Echo

A Mustang with a four-cylinder turbo instead of a 5.0 V8? To many purists, it borders on heresy.And yet, the 2.3 EcoBoost has its own logic. 290 horsepower, lively handling, finally affordable taxes and controlled fuel consumption. This is the Mustang that lets you live the myth on a daily basis, without putting your budget on the line.Except that one detail remains, one that nobody can pretend to ignore. When you drive a Mustang, you expect to hear a Mustang…

Lotus Eletre: giving the Lotus sound DNA back to an electric SUV with an Active Sound Thor Level 2 + Echo

In 2023 Lotus launched the Eletre. A hyper-SUV weighing more than 2.5 tonnes, fully electric, technologically spectacular. A brilliant car in many respects. But also, by its very nature, completely silent. For the brand's purists, that silence is more than a detail. It is a fundamental question about what made the soul of Lotus.The owner of this Eletre, a former Exige driver, approached the car with exactly that nuance. He embraced his transition to electric driving, but he was not willing to give up the sensory identity that had always drawn him to Lotus. Here is how a Thor Level 2 + Echo Kit reconciled the two.

BMW i8 Roadster: giving BMW's most spectacular silhouette the voice it deserves with an Active Sound Thor Level 4

Park a BMW i8 Roadster anywhere and watch what happens. The butterfly doors opening towards the sky, the futuristic supercar silhouette. Within seconds, every head turns and the car becomes the centre of attention.Then the engine starts. And that is where the deal breaks down. This spectacular machine, looking like a prototype that has escaped from a motor show, springs to life with a surprisingly civilised purr. A three-cylinder petrol engine paired with an electric motor. Technically impressive. Emotionally frustrating.The owner of this i8 Roadster wanted to fix that last imbalance. Here is how a Thor Level 4 Kit finally gave the car a sound to match what it is.

Porsche Cayenne: Restoring the Porsche Sound DNA with a Thor Active Sound Level 2 System

Driving a Porsche Cayenne means embracing a paradox. On one hand, the Stuttgart crest, a rich motorsport heritage, and the promise of raw driving emotion. On the other, a comfortable, versatile SUV designed to cover long distances in near silence.But a Porsche should be heard. It should have a voice — and that’s exactly what we gave it with the Thor Active Sound system.

BMW X5 (F15): Transforming the Sound Presence of a Diesel SUV with a Thor Level 4 Kit

The BMW X5 F15 commands respect. Its imposing silhouette, massive grille, and stance as a large German SUV give it an immediate presence on the road.

Mercedes GLS 350d: installing a Thor Active Sound Level 4 on a luxury 7-seat SUV

The Mercedes GLS is a rolling monument.

BMW 330i F30: make a 3 Series sound like an M3 with Active Sound Thor

Let’s be honest: choosing a 330i instead of an M3 is not a compromise. In many cases, it’s the smartest decision.Lower taxes, cheaper insurance, better fuel consumption, proven reliability and real everyday comfort. On paper and in real life, the 330i wins almost every rational argument.Except one. And it comes back at every start, every acceleration, every weekend drive. That’s the one thing this installation was designed to fix: the sound.

Diesel cars are very practical and efficient. This is what everybody loves them for. Especially if it is a family crossover. 

BMW X5 G05: why owners choose Active Sound Thor after a few years

When you take delivery of a BMW X5, the first months are all about discovery. You explore the technology, fine-tune the seat position, test the driving modes and enjoy the feeling of a new car.But after two or three years, something changes. The owner knows the car inside out. He understands exactly what it delivers, and more importantly, what it doesn’t. And at that point, one question keeps coming back: “Why can’t I hear anything when I accelerate?”The owner of this 2023 X5 contacted us three years after purchasing it.

BMW 530d G30: giving high-mileage drivers back the pleasure of driving with a Thor Level 4 Kit

There is a category of BMW 5 Series owners that rarely gets talked about. Those who cover 40,000, 50,000, sometimes 70,000 kilometres a year. Executives on the road, business owners, senior sales managers. For them, the car is not a weekend hobby: it is a rolling office.The 530d ticks every box for this profile: diesel range, comfort, reliability, image. On paper, it is the perfect car for this kind of use.But after two or three years spending more time behind the wheel than at a desk, many of them notice the same thing: the car has become too transparent. Here is why this installation changed everything.

Mercedes V-Class: giving a family van the sound of a sports car with an Active Sound Thor

A practical everyday car that becomes something unexpected the moment you press the accelerator. Here is how a Thor Level 2 Kit turned this diesel van into one of the most surprising vehicles on the road.

Audi Q7: giving German discretion a voice again with Active Sound Thor Level 2

Choosing an Audi Q7 over a BMW X5 or a Mercedes GLE is rarely a coincidence. It is usually the choice of a very specific vision of premium motoring: less ostentatious, more precise, almost silent in the way it asserts its presence.Audi has always embraced this philosophy of discretion. The problem is that by refining this identity so much, the brand has also softened what once made its legendary Quattro models feel alive. Here is how a Thor Level 2 kit gave this diesel Audi Q7 its voice back, without betraying the elegance that makes it so distinctive.
