Mazda prepares MX-5 for an electric future

MAZDA has confirmed the next-generation MX-5 is being engineered with an electric future in mind, although the Japanese manufacturer has stopped short of confirming the iconic roadster will launch with a battery-electric powertrain.

Speaking to Germany's Auto Motor und Sport, Mazda president and chief executive Masahiro Moro said the successor to the world's best-selling roadster would need to accommodate changing global regulations while remaining true to the lightweight philosophy that has defined the MX-5 for more than three decades.

"The successor must also be ready for a scenario without a combustion engine," Mr Moro said.

"The challenge for us is to make the basic structure lighter without using exotic materials like carbon fibre."

While the comments represent Mazda's strongest indication yet that an electric MX-5 is under development, they stop short of confirming a battery-electric version will form part of the production line-up.

Instead, the remarks suggest Mazda is future-proofing the platform so it can accommodate multiple powertrains should market demand or legislation require it.

Weight remains the overriding priority.

Mr Moro said engineers are targeting a kerb weight of between 1000kg and 1200kg - a challenging objective given the additional mass associated with battery-electric powertrains.

Maintaining the MX-5's lightweight character has been identified by senior Mazda executives as essential to preserving the model's renowned handling and driver engagement.

The current ND-generation MX-5, launched globally in 2015, weighs between approximately 1070kg and 1140kg depending on specification and remains one of the lightest sports cars on sale today.

Other Mazda executives have also indicated that electrification is inevitable but caution that it must not compromise the vehicle's core character.

Earlier this year, Mazda Motor Europe's Director of Research and Operations, Christian Schultze, said a fully electric MX-5 would fundamentally alter the vehicle's architecture.

"The moment you go fully electric, you fundamentally change the car's architecture," he said.

"That means different proportions, different weight, a different balance."

Mr Schultze said his preference would be for an electrified MX-5 rather than a fully battery-electric model, while European design director Jo Stenuit has previously confirmed the next-generation roadster is expected to receive at least some form of electric assistance.

"Nothing is set in stone yet, but I'm certain that car will have some form of electric power assistance," Mr Stenuit said.

"Mild hybrid will be the least of the options."

Industry speculation continues to suggest the next MX-5 will retain an internal combustion engine, potentially adopting Mazda's forthcoming Skyactiv-Z four-cylinder 2.5-litre petrol engine with some level of hybrid assistance.

A battery-electric derivative is also considered increasingly likely later in the model's lifecycle, although Mazda has not confirmed any technical details or launch timing.

The company has consistently maintained that preserving the MX-5's "Jinba Ittai" philosophy - the feeling of unity between driver and machine - remains central to development regardless of powertrain.

The next-generation MX-5 is expected to replace one of the automotive industry's longest-running model generations, with the current ND entering its eleventh year on sale.

Mazda has yet to announce when the fifth-generation MX-5 will make its global debut.
