Talking at a convention held at the side of the Japan Mobility Present (JMS) in Tokyo final week, the corporate’s powertrain chief Takashi Uehara stated there’s no timeline for the top of diesel-powered Toyotas.

Nonetheless, Toyota repeated its dedication to ‘decarbonisation’ on the JMS, primarily through its trademark petrol-electric hybrid automobiles. However whereas it wouldn’t verify it’s growing a diesel-electric hybrid powertrain, it didn’t rule out including electrification to diesel engines.
Whereas the corporate’s vary of hybrid fashions is dominated by petrol engines, the 48V mid-hybrid HiLux and Prado ‘V-Energetic’ fashions launched in Australia in 2024 have been the primary electrified diesel automobiles to reach in native showrooms, though Toyota doesn’t seek advice from them as hybrids.
“There may be excessive potential for ICE [internal combustion engines] – the combo of fuels that’s extremely accommodating of various sorts,” Uehara-san stated.

“Some areas need the battery-EV and [also] have the ICE – it’s not a sure deadline that now we have or sure 12 months; I believe this sort of demand will likely be ever present,”
“It’s the identical for gasoline [petrol] and diesel fuels, too, and if we attempt to develop the chances, availability, now we have to look into the varied engine availabilities, not simply the engine alone.”
On diesel engines particularly, Uehara-san stated: “We would not have a sure deadline that we’ll finish improvement or manufacturing, however emissions rules will turn into more durable going ahead.”

Toyota, the world’s largest automaker, was criticised for being gradual to introduce EVs and never making a dedication to go EV-only inside a sure timeframe like lots of its rivals. However now many business consultants regard its strategy as prudent as different automakers stroll again their all-EV commitments and mop up important monetary losses resulting from extra EV manufacturing capability and/or unplanned ICE car improvement.
“The fee for admission goes to be heavier and that will undermine the recognition of the diesel sooner or later – that’s a risk,” Uehara-san added.
“We will likely be selling our electrification and likewise discount of CO2, however persevering with the large torque on the diesel engine – sustaining that – as we proceed our analysis and improvement.”
If Toyota does embrace diesel hybrid know-how, it received’t be the primary automaker to take action. And whereas a number of European manufacturers beforehand provided diesel-electric powertrains, Chery Australia’s first ute is anticipated to be powered by a diesel-electric plug-in hybrid system, which might make it the primary car of its variety Down Underneath.
