MAZDA is switching its Heritage Fleet in the UK to run on sustainable petrol.

Highlighting the role sustainable fuel can play in de-carbonising classic cars the 15-car Mazda UK Heritage Fleet will be filled with Sustain Classic Super 80 supplied by Coryton, each time the cars are driven or loaned out.

None of the cars required modification to run on the petrol, which can be used by any standard petrol-fuelled vehicle.

Developed by UK firm Coryton, Super 80 is one of three fuels in the recently launched Sustain Classic range. Super 80 is a second generation bio-fuel created using 80 per cent agricultural waste, such as straw, by-products and waste from crops which wouldn't be used for animal or human consumption.

The fuel offers a reduction of at least 65 per ceny in greenhouse gas emissions when compared to fossil fuels.

In November 2022 Mazda drove a 2.0-litre MX-5 for 1,000-miles around the UK, lapping a circuit in each home nation all powered by sustainable fuel from Coryton - underlining the potentialsustainable fuels have for decarbonising motorsport and the many millions of combustion engine cars that will remain on our roads for decades to come.

The switch to fuel the heritage fleet in the same way further highlights how sustainable fuel is a real and credible player in efforts towards net zero, while at the same time allowing the continued enjoyment and preservation of classic vehicles.

David Richardson, director at Coryton, said: "We're delighted that Mazda has decided to place its trust in SUSTAIN Classic to fuel its important fleet of heritage vehicles. We believe that SUSTAIN Classic is the world's first ever publicly available sustainable fuel catering for classic vehicles and we hope that these fuels will give classic car owners confidence that there are options for them to continue running their vehicles in a sustainable way in the years to come."

"Now is a vital time to start proving that sustainable fuels can have a real future fuelling our transportation - past and present. While other technologies are given the necessary time to develop, sustainable fuels are here and ready to go to help tackle emissions from the existing fleet of classic and modern cars on our roads - and can be scaled up relatively quickly if needed. Every kilogram of CO2we avoid adding to our atmosphere, by replacing fossil fuel with sustainable fuel, is a win. We don't instantly have to go for the full switch to start making a genuine impact. As more feedstocks become available, these fuels will start to contain even higher levels of traceable sustainable elements."

The Mazda UK Heritage Fleet features 15 cars with engines ranging from rotary to both four and six-cylinder petrol, all of which will now be running on Coryton's sustainable fuel.

Commenting on the switch to Sustain Classic by Coryton, Jeremy Thomson, managing director, Mazda Motors UK, said: "Our heritage fleet highlights Mazda's long tradition of engineering ingenuity and stand out design. Mazda's ‘never stop challenging' approach can be seen throughout our heritage, so it's great that we can highlight the potential sustainable fuels can play in the future as part of a multi-solution approach to CO2reduction.

"While our new car range will feature ever more electrification as part of this multi-solution approach, using a sustainable petrol in our heritage cars is a great way to highlight the role these fuels can have in reducing the environmental impact of the combustion engine cars that will remain on our roads for decades to come."

Mazda UK's 1973 Mazda RX-3 was demonstrated at the recent Flywheel Festival at Bicester Motion, where it ran powered exclusively by Coryton's Super 80 Sustain Classic petrol.
