Our story

Colmis was founded in 1985. What started as a modest but ambitious initiative by two local entrepreneurs of Arjeplog, with one customer and one track, gradually emerged into a well-known business, today the permanent winter testing home to some of the biggest manufacturer and supplier names in the global automotive industry and welcoming engineers from all over the world.

why Colmis

Our vision

Our goal is very clear: delivering the most advanced and customised winter test solution on the market. 

We aim at full customisation: being responsive, flexible and proactively finding solutions to our customers’ needs, whatever they may be. 

If it is possible and viable, we always try our best to make it happen.


Our mantra is “Everything you need in one place”.

Whether it’s facilities (workshops, tracks, cold chambers, chargers), a testing infrastructure (tracks on land and on the frozen lakes) or services (mechanics, engineers, drivers and coordinators)… these are all things you will find at Colmis.

together we are Colmis

Our infrastructure would be nothing without our team: Colmis is about the people.

We see our customers as our partners. Only a successful winter testing season for them will determine a successful winter testing season for Colmis. 

The sense of friendship and teamwork between Colmis and its international clientele is founded on a series of pillars that are what enable the delivery of outstanding customer service.

Accreditations & Certifications

Certification is an integral part of the organization and Colmis AB is accredited following ISO 9001 (Quality Management System), ISO 14001 (Environmental Management System) and ISO 45001 (Occupational Health and Safety Management System) standards.

Colmis also has the highest AAA rating from Soliditet, the leading provider of credit- & business information in the Nordics.

Why Arjeplog

a global automotive hub

Every winter Arjeplog becomes a centre for the automotive industry and draws thousands of engineers from all over the world.  

The consistent low temperatures, the many lakes in the area and the scarce population is how it all started several decades ago.

Colmis has played a pivotal role in contributing towards the development and transforming Arjeplog into an annual meeting point for automotive manufacturers and suppliers alike.

reasons to choose Arjeplog

It’s much more than a cold place. It’s where the automotive industry meets. This is a factor by itself. OEMs and suppliers want to be close to one another.

It’s scarcely populated. Only 2,800 people live in the greater region. Meaning testing can be done even on public roads with enough discretion, away from the eyes of the curious.

Varied kinds of roads. Not only our proving ground offers specialised tracks, you can also complete durability driving mileage on the surrounding public roads.

Despite being in a remote area, it has easy access with an airport just an hour drive away.

consistent below zero temperatures

Our winter roughly goes from October until mid April, while the testing season takes off in November and concludes end of March / start of April. During these months the temperatures are consistently below zero degrees. 

The coldest months are usually January and February, which is when the season peaks, as it’s almost guaranteed that the lakes are frozen and the temperatures are very low. However, depending on the testing you need, December or March can be more fitting, sometimes colder… and definitely less crowded.

Even if the average lows are -15 or -20 during the winter months, there are multiple days and weeks a month where -30 and colder is not only normal: it is the norm.

”We are an open proving ground. Open in the sense that, in addition to our long-term customers, we also offer our facilities and services to other companies for shorter-term projects. Many of these companies come back again and again.

The site also welcomes new companies, whether start-ups or established enterprises, every year.”

Mikael Hallin, CEO at Colmis

”Environmental responsibility is high on the list for us and, apart from now sourcing our power from renewable energy sources, the company has also made certification an integral and visible part of the organization.

Today Colmis is ISO 9001 (Quality Management System), ISO 14001 (Environmental Management System) and ISO 45001 (Occupational Health and Safety Management System) accredited.”
