Mazda MX-30 R-EV rotary plug-in hybrid revealed
4 min read
Mazda has launched a 3rd member of its quirky MX-30 crossover vary; a plug-in hybrid utilizing a model new rotary engine as a generator.
This long-in-development mannequin was as soon as firmly on Mazda Australia’s agenda, however seemingly not, with the launch now being targeted on Europe.
The MX-30 e-Skyactiv R-EV revealed on the Brussels Motor Present at this time gives a claimed 85km of pure electrical vary, with the rotary engine then serving as a range-extender and booster.
Why a rotary? Mazda cites packaging advantages for one: Rotary engines are extra compact than piston engines with the identical output.
However in fact it’s all the time been wanting to discover a strategy to deliver again certainly one of its signature applied sciences for the electrical age – on this case as a generator not a drive unit. Mazda’s final rotary, the RX-8, was discontinued in 2012.
But it seems unlikely to return to Australia, within the short-term a minimum of.
“Globally, Mazda introduces fashions and powertrains to markets primarily based on a multi-solution technique that considers regional variations in power manufacturing, environmental rules, and buyer wants,” the corporate’s native division instructed us.
“In Australia, this 12 months we’re focussed on launching our new massive platform hybrid fashions in Mazda CX-60 and Mazda CX-90, plus a variety of updates throughout key mannequin strains, together with Mazda CX-8 and Mazda6.”
In different phrases, don’t search for it any time quickly.
In Europe the MX-30 e-Skyactiv R-EV joins the MX-30 M Hybrid (a very gentle hybrid) and MX-30 pure EV, with its restricted vary.
The drive unit operates as a sequence hybrid moderately than a parallel hybrid. Meaning the 55kW and 830cc displacement rotary engine’s job is to generate cost for the electrical motor moderately than immediately driving the wheels.
The rotary will even spring to life when extra energy is required than the battery stage can ship to the motors – for instance, when accelerating – primarily based on the diploma of accelerator opening. But it surely’s by no means immediately related to the wheels.
The MX-30 eSkyactiv R-EV derives its claimed 85km combined-cycle electrical vary from a 17.8kWh lithium-ion battery, which powers the 125kW and 260Nm entrance motor. It’s able to a claimed 9.1 second 0-100km/h time.
This battery is identical because the one used within the bigger CX-60 PHEV.
It’s on the bigger facet for a PHEV – ergo the longer than common 85km WLTP combined-cycle vary, which extends previous 100km in city visitors when you need to use extra regenerative braking.
As soon as depleted, the brand new rotary engine with a 50L gasoline tank kicks in. Mazda says it has fitted this newest rotary with higher apex seals than its Renesis forebear and minimize 15kg in weight utilizing aluminium for the facet housing.
Mazda has not stated what gasoline effectivity to count on when counting on this generator, nor subsequently the automobile’s full vary with tank and battery mixed. Evidently it’s quite a bit longer than the MX-30 pure EV’s 224km declare, making this mannequin extra suited to lengthy journeys.
The MX-30 e-Skyactiv R-EV is appropriate with single-phase and three-phase Kind 2 AC charging, and fast CCS charging at a most 36kW DC.
The battery may be charged from 20 per cent SoC to 80 per cent in roughly 25 minutes. One-phase 7.2kW regular AC wallbox charging will take roughly 90 minutes. The time on a house powerpoint isn’t specified, however you typically trickle cost in a single day.
The MX-30 e-Skyactiv R-EV additionally helps vehicle-to-load (V2L) energy provide performance as much as 1500kW.

Background
We spoke with Mazda Australia advertising director Alastair Doak again in March 2022 concerning the native plans for the MX-30 rotary, and the reply was optimistic for native patrons who need a fair quirkier providing.
“Will probably be unveiled this 12 months,” he stated, earlier than the automobile was clearly delayed. “It’s undoubtedly getting very near manufacturing, just about the event is completed on the automobile. We’re excited.”
Nevertheless, the corporate modified its tune within the interim, with Mr Doak telling us extra not too long ago in October that its Australian prospects had grow to be cloudier – maybe no shock given the MX-30 EV’s modest gross sales right here.
“The automobile does exist and can exist,” stated Mr Doak, including the MX-30 rotary range-extender was nonetheless on the native division’s want record.“I feel subsequent 12 months it will likely be unveiled, and from there I’m not fairly positive if it is going to come to Australia.”
Now we all know it’s not right here for a minimum of the subsequent 12 months.
Final 12 months, Mazda did submit a variety of logos to IP Australia for the naming rights to ‘e-SKYACTIV R-HEV’ and ‘e-SKYACTIV R-EV’, so maybe in time…
