To demonstrate the potential role sustainable fuels can play in reducing greenhouse gas emissions when used as an alternative to fossil fuels, the launch cars on the Mazda UK all-new Mazda CX-5 launch will be powered by a 100 per cent second-generation biofuel with no fossil fuel component.
Provided by SUSTAIN Fuel Technologies, the SUSTAIN 100 95 RON E10 second-generation biofuel is created from biomass such as food and agricultural waste and other non-food by-products. This content utilises the carbon that already exists in our atmosphere, which plants absorb as they grow, recycling it rather than releasing additional CO2 that is currently locked underground in fossil fuels.
The all-new Mazda CX-5 is powered by a 2.5-litre e-Skyactiv G 141ps petrol engine, paired with 24V Mazda M Hybrid technology, replacing the previous 2.0-litre base unit. This engine delivers confident performance with improved torque for quicker response, seamless acceleration, and better driving comfort. Producing 141ps and 238 Nm of torque, the front-wheel drive variant accelerates from 0-62mph in 10.5 seconds, while cylinder de-activation enhances efficiency. Powering this engine with SUSTAIN 100 95 RON E10 fuel requires no modification and delivers no change in performance.
Continued internal combustion engine development blended with electrification is a well-established example of Mazda’s powertrain innovation, enhancing vehicle efficiency as part of Mazda’s Multi-Solution Approach. This strategy is well-suited to the application of sustainable fuels as a compelling alternative to fossil fuels and a way of reducing greenhouse gas emissions in combination with efficient engines.
The use of SUSTAIN fuel at the all-new Mazda CX-5 launch is the latest example of Mazda’s commitment to demonstrate the role, alongside electrification, that sustainable fuel can play in the transition away from fossil fuel. Mazda UK has powered its Heritage Fleet with a sustainable fuel blend since 2023. During the same year, an MX-5 was the first car to complete a lap of a racing circuit in all four UK home nations while sustainably fuelled, and in 2024 a quartet of MX-5s became the first cars to drive from Land’s End to John O’ Groats using sustainable fuel, while last year Mazda CX-30s drove from the Baltic to Arctic using the same fuel.
Each of these activities took place using fuel from SUSTAIN, and they demonstrated the role sustainable fuels can play in transitioning modern and classic cars away from fossil fuel. They also highlight how sustainable fuels could complement Mazda’s Multi-Solution approach to achieving climate neutrality.
Commenting on the use of SUSTAIN for the Mazda UK CX-5 press launch, Suresh Nahar, Brand Manager for SUSTAIN, said: “we are delighted to be partnering with Mazda to fuel the launch of its all-new CX-5 with 100 per cent sustainable fuel. Set against Scotland’s stunning scenery and marking an exciting new era for this iconic model, using a fuel with no fossil fuel content highlights the many benefits we can unlock through advanced technology. What better place to showcase the vital role sustainable fuels can play in building a brighter future for the ICE and fuel security.”
Adding, “the bespoke SUSTAIN fuel we’ve created for this Mazda event will deliver a greenhouse gas saving of over 80 per cent during the drive, when compared to a fossil fuel. While this fuel is currently not available commercially, we do offer fuels for the public that are available with varying levels of sustainable content. As an example, SUSTAIN Classic became the first publicly available sustainable fuel when it launched in 2023. The collection includes products with varying levels of sustainable content to suit a range of customer needs and price points – from 33 per cent to 80 per cent – with the Mazda UK Heritage Fleet powered by 80% SUSTAIN Classic. Our commercially available fuels allow customers to follow in the footsteps of brands like Mazda and start powering their car sustainably.”

Across the week-long launch event, which starts next week, the full fleet of 20 Mazda CX-5s will be exclusively powered by SUSTAIN, with more than 70 guests experiencing the new Mazda CX-5 powered by fuel with no fossil fuel component. Commenting on the use of SUSTAIN, Mazda Motors UK, Managing Director, Jeremy Thomson, said: “at Mazda we will continue to develop the internal combustion engine to meet consumer demand in parallel with our battery electric development, as part of our multi-solution approach. In Japan we are researching and developing engines to run on biofuel as well as algae fuels and synthetic fuels, and in Europe we are a member of the eFuel Alliance. Using a fuel with no fossil fuel component on our all-new Mazda CX-5 UK media event is a great illustration of the benefits of combining an efficient internal combustion engine and advanced biofuels to save CO2 emissions”.
The all-new Mazda CX-5 is available to order and configure now ahead of the first customer deliveries in the summer. With refined driving dynamics, an evolved and distinctive Japanese design and enhanced versatility, the all-new Mazda CX-5 is crafted to elevate every journey – wherever it leads.
