Extreme Mercedes-Benz AMG Mythos prototype spotted testing near the Arctic Circle

An extreme Mercedes-Benz AMG prototype has been spotted testing in one of the coldest places on Earth.

Wrapped in heavy camouflage and charging through snow near the Arctic Circle, the car looks far more serious than a routine development mule.

Mercedes-AMG has confirmed this is the second model in its ultra-exclusive Mythos series, and it’s currently undergoing intensive cold-weather testing in Sweden.

Details are still tightly guarded, but this clearly isn’t a low-stakes development exercise.

Mercedes-Benz AMG pushed to the limit in Arctic testing

Cold-weather testing isn’t just a box-ticking exercise, especially at this level.

Near the Arctic Circle, temperatures plunge, traction disappears, and mechanical systems are pushed into situations most road cars will never experience. 

That’s exactly why Mercedes-AMG is here. 

These tests are designed to validate performance, reliability, and overall drivability when conditions are at their harshest.

Even under camouflage, the prototype stands out. 

While it’s clearly based on the Mercedes-Benz CLE platform, AMG isn’t trying to hide that this car goes much further. 

The proportions look more aggressive, the stance more purposeful, and the overall presence more confrontational than anything currently wearing CLE badging.

That tracks with how AMG is positioning the car internally. 

This isn’t being developed as a high-performance variant aimed at volume sales. 

Instead, it’s framed as a statement model, backed by a powerful drivetrain and engineered to deliver drama as much as speed.

Cold-weather testing plays a key role in that ambition. 

Steering response, power delivery, braking systems, and electronic stability controls all behave differently on ice and snow. 

For a car that’s meant to sit at the extreme end of AMG’s lineup, those systems have to feel predictable even when grip is at its worst.

And that’s before you factor in the Mythos badge.

Why the Mythos series exists at all

The Mercedes-Benz Mythos series exists outside AMG’s usual rulebook.

It’s a small, tightly curated lineup of limited-edition collector cars, built to explore ideas that don’t need to make sense on a spreadsheet. 

The first entry, the Mercedes-AMG PureSpeed (featured in the video above), made that clear immediately. 

With no roof and no windshield, it was less about practicality and more about pushing emotional design and engineering to an extreme.

This second Mythos model appears to follow the same philosophy, even if the execution looks very different.

By basing it on the CLE and then radically reworking it, AMG seems to be using the series to test how far it can stretch familiar platforms before they become something entirely new. 

It’s also a way to separate its most experimental ideas from the broader AMG range, where expectations around usability and production scale still apply.

For now, Mercedes-AMG isn’t saying when the car will be revealed, what it will be called, or how many will be built. 

But the sight of it being driven hard in Arctic conditions says enough.

This isn’t a concept designed to sit under lights. 

It’s being engineered to prove a point.
