Mazda CX-30s Complete Epic Baltic to Arctic Journey Using Sustainable Fuel

In an impressive demonstration of alternative fuel capabilities, a fleet of twelve 2025 Mazda CX-30s recently completed an extraordinary journey spanning over 1,300 miles from the Baltic Sea to the Arctic Circle. This remarkable expedition showcased not only the vehicles' performance in challenging conditions but also highlighted Mazda's commitment to exploring sustainable fuel solutions as part of their multi-solution approach to reducing carbon emissions.

The journey began in Malmö, Sweden, situated on the Baltic coastline, and concluded in Tromsø, Norway—a coastal town located more than 200 miles north of the Arctic Circle. Throughout this extensive northern European trek, the vehicles traversed through Sweden, Finland, and Norway, covering precisely 1,344 miles while exclusively powered by SUSTAIN's 100 per cent biofuel, which contains zero fossil fuel components.

The New e-Skyactiv G Engine

The 2025 Mazda CX-30 models featured in this expedition were equipped with the newly introduced 140ps e-Skyactiv G 2.5-litre petrol engine. This powerplant represents a significant advancement over its predecessor, incorporating sophisticated cylinder deactivation technology paired with Mazda's innovative M Hybrid mild-hybrid system.

This engineering combination has yielded measurable improvements in both fuel economy and emissions reduction during real-world testing when compared to the outgoing 2.0-litre engine previously offered in the CX-30 range.

Sustainable Fuel as a Viable Alternative

The Baltic to Arctic expedition serves as compelling evidence of sustainable fuel's potential as an immediate solution for reducing greenhouse gas emissions from existing internal combustion engine vehicles. Particularly noteworthy is that these CX-30 models required absolutely no modifications to operate efficiently on the sustainable biofuel.

The vehicles achieved an impressive average fuel economy exceeding 40 miles per gallon throughout the journey, demonstrating that performance and efficiency need not be compromised when transitioning away from conventional fossil fuels. This flexibility represents a significant advantage in the broader context of reducing transportation-related carbon emissions.

Understanding SUSTAIN Biofuel Technology

The sustainable fuel powering the CX-30 fleet was provided by SUSTAIN, a company specialising in second-generation biofuels. Unlike conventional fuels derived from fossil sources, SUSTAIN's product is manufactured entirely from agricultural waste materials that would otherwise serve no purpose for human or animal consumption.

This innovative approach to fuel production creates a more environmentally responsible cycle. The biofuel utilises carbon already present in our atmosphere—carbon that was captured naturally by plants during their growth cycle and is then released again during combustion. This closed-loop system stands in stark contrast to fossil fuels, which release additional carbon dioxide that has remained sequestered underground for millions of years.

Mazda's Broader Commitment to Sustainable Fuels

The Baltic to Arctic expedition represents just one component of Mazda's ongoing efforts to showcase the potential of sustainable fuels in transitioning away from fossil fuel dependency. Since June 2023, Mazda UK has powered its entire Heritage Fleet with sustainable fuel, preserving automotive history while reducing environmental impact.

In 2023, a Mazda MX-5 became the first vehicle to complete laps at racing circuits across all four UK home nations while running exclusively on sustainable fuel. Following this achievement, a quartet of MX-5s made history as the first cars to travel from Land's End to John O'Groats—the traditional route spanning the full length of Great Britain—using only sustainable fuel.
