Currently reading: Mazda set to reveal renewable-fuel sports car at Tokyo motor show

Brand aims to offer combustion-engined driver’s cars “for as long as possible”

Mazda will reveal a new sports car concept that could be powered by renewable fuels at the upcoming Tokyo motor show.

An official preview image leaves much to the imagination, but it shows the concept is a four-door coupé with a steeply raked roofline. The cut-outs around the car’s rear deck suggest it may also have an active spoiler.

Mazda said the concept will demonstrate how it aims to build sustainable driver's cars into the distant future – "toward the year 2035" – with the tagline "the joy of driving duels a sustainable future".

Alongside the concept, the brand will show a new CO2 capture system claimed to cut emissions the more a car is driven, as well as a carbon-neutral fuel produced using algae.

Mazda has become one of the industry’s largest proponents of renewable fuels as an alternative to battery-electrification, owing to its legacy of building lightweight sports cars such as the MX-5. Transitioning such models to battery-electric power without a significant increase in weight poses a real challenge, given existing battery technology.

Last year, it partnered with Toyota and Subaru in an engine development project described by Toyota CEO Koji Sato as a “friendly competition”, aimed at further optimising combustion power. 

Mazda president and CEO Masahiro Moro said: “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.”

Mazda presented a new development of its signature rotary engine designed to fit into the same space as an electric motor, allowing it to be transplanted into existing battery-electric models. 

Mazda also races an MX-5 and a 3 hatchback powered by carbon-neutral fuels in Japan’s Super Taikyu series.

I love the clean surfaces of Mazda, but the image shown seems to exaggerate the worst part of the Mazda3, the heavy C-pillar that reduces rear three-quarters visibility, and makes that area look too heavy from the outside.

You just know it's going to be mouth-wateringly gorgeous. Nobody does desirable mainstream styling better than Mazda.

"Mazda presented a new development of its signature rotary engine designed to fit into the same space as an electric motor, allowing it to be transplanted into existing battery-electric models" and just why anyone convert a Nissan Leaf to run a rotary engine.  Maybe a small underpowered rotary could fit in the space but have you forgotten the exhaust, radiators, gearbox, clutch, fuel tank, electrics etc etc.

Come on Mazda even you cannot believe this is a goer of a concept.
