Mazda Teases New Four-Door Coupe Concept for Tokyo Motor Show

Mazda’s upcoming four-door coupe concept is said to run on renewable fuels, set to debut at the Tokyo Motor Show.

Another day, another Japanese automaker teased its lineup for the upcoming Japan Mobility Show 2025 (JMS), as Mazda just unveiled a teaser image of its upcoming concept model. Interestingly, this supposed four-door coupe concept is part of Mazda’s fight to keep its combustion engine “for as long as possible,” where it is said to run on renewable fuels.

Described as “the vision for future Mazda vehicles,” this concept will serve as a design and technology blueprint for upcoming models from the Hiroshima-based marque. At first glance, the single teaser image highlights the concept’s sleek profile, featuring a fastback-style roofline with sculpted shoulders, thick D-pillars a la Mazda3 Liftback, and frameless windows with no physical side mirrors.

From said image, we can also see that this sleek fastback coupe comes with four doors, thus hinting at a sporty four-door GT saloon style. But then again, this could also be a sleek coupe crossover, possibly a continuation of the popular Mazda CX-30.

Beyond its sleek style, this mysterious concept will play an integral role in shaping Mazda’s future, as it will demonstrate how the company aims to build driver-centric cars that are still sustainable, with the tagline "the joy of driving fuels a sustainable future."

That said, it may take a while before we get to see the production version of this sustainable concept, as Mazda says it will come out "toward the year 2035," thus giving the automaker roughly a decade to sort things out.

Alongside the concept, Mazda will also display a new system for capturing carbon dioxide that it claims can cut emissions the more the car is driven, plus a new carbon-neutral fuel produced using algae.

Unlike most Western automakers out there, Mazda has always been one of the industry’s key believers in renewable fuels as opposed to straight-up battery EVs, so much so that the automaker even pledged to keep internal combustion engines (ICEs) as long as it could.

“We will continue to offer customers exciting cars by honing internal combustion engines for the electrification era and expanding the multi-pathway possibilities for achieving carbon neutrality,” said Masahiro Moro, Mazda president and CEO.

Prior to this, Mazda had partnered with Toyota and Subaru in an engine development programme, with the aim of further optimising the use of combustion power with carbon-neutral fuels.
