It might not seem to be it, however Mazda‘s rotary ambitions are alive and effectively.

True sufficient, that silence has been damaged, as Mazda has lately introduced that the Iconic SP idea’s development–or regardless of the ensuing rotary range-extender electrical car (EV) manufacturing sports activities automobile will be–only wants one last ingredient for it to be produced. So buckle up, girls and gents, rotary followers of each technology, here is what you might want to find out about Mazda’s upcoming production-intent Iconic SP idea. Oh, and also you’d higher stick round to seek out out what it plans for the next-generation MX-5 as effectively.

Mazda Launches New Sporty Electrical Sedan For A Shockingly Low Value

With a purpose to provide the latest and correct info doable, the information used to compile this text was sourced from Mazda and different authoritative sources, together with MotorTrend and Highway and Monitor.
The Substances That The Iconic SP Already Has
With a purpose to perceive how shut we truly are to a brand new rotary sports activities automobile, now we have to judge what Mazda’s Chief Technical Officer, Ryuichi Umeshita, informed MotorTrend. Spoiler alert, they have already got every thing that is wanted to provide the Iconic SP, aside from one last hurdle that has nothing to do with the automobile’s mechanicals.
The Rotary Is Alive, And In Two Guises
We might not see it but, however Mazda is already at or close to completion of the Iconic SP’s promised rotary vary extender engine. This may present juice to the batteries for the twin electrical motor, all-wheel drive (AWD) system that was promised to have 365 horsepower. Sure, whereas it would not sound just like the glory days of the RX-7 with the rotary engine being the principle ingredient, Umeshita promised this: “You’ll be able to anticipate Iconic SP can be a superb successor for RX-7.”
The MX-30 R-EV was by no means bought in the US as a result of its rotary vary extender engine didn’t meet emissions laws. Nonetheless, the brand new, extra highly effective rotary vary extender will, in response to Umeshita. In truth, they’ve even managed to discover a method for the rotary engine to combust not simply classic-old oxygen, but in addition hydrogen and different fuels.
However here is excellent news for people who need the rotary to be the principle ingredient. Sure, there may even be one other model of the Iconic SP whereby the rotary engine is the first powertrain. Requested if a pure EV model of the Iconic SP is in improvement, Umeshita says it’s doable, however not deliberate.
And It Solely Wants This Closing Ingredient
The ultimate ingredient that the Iconic SP wants to ensure that it to be produced shouldn’t be even immediately associated to the mechanics of the automobile. That is as a result of the one factor for this automobile to be greenlit for manufacturing is a viable enterprise case. Guys, if you happen to’re a type of who’ve been eager for a rotary sports activities automobile to make a comeback, then you definately higher put your cash the place your mouth is.
Sadly, particularly in in the present day’s international financial system that is pushed by tariffs, the timing for a stable enterprise case is trickier than ever. Time the enterprise case proper, and Mazda would simply recuperate the price of improvement. In any other case, the Iconic SP may flip into the Lexus LFA, whereby the Japanese supercar by no means made cash for each mannequin it produced.

Complement, Not Change The MX-5
No, the Mazda MX-5 will not be discontinued. As a substitute, the Iconic SP, with its incrementally bigger but nonetheless compact footprint, the long run rotary sports activities automobile will complement the MX-5. Just like the MX-5, the Iconic SP’s manufacturing mannequin is not going to be a quantity vendor. With 27,669 models bought globally in 2024, the MX-5 is a tiny drop within the bucket for Mazda’s general gross sales of 1,277,578 models.
Nonetheless, till now, its title when it hits the manufacturing line remains to be a thriller. Although the expectation is that it’ll honor the RX-7’s title, what you’ll be able to assure is that it undoubtedly will not be referred to as the Cosmo, a reputation that was beforehand used for an extended line of luxurious two-door coupes with a rotary engine. Masashi Nakayama, Common Supervisor of Mazda’s Design Division, describes the Iconic SP to be a pure sports activities automobile with a Coke-bottle form, huge haunches, and an extended nose–design elements which are removed from what the Cosmo mannequin lineage was recognized for.

Coming into its fifth technology in a 12 months or two, work is already being executed to create an MX-5 that maintains its standing as an inexpensive, light-weight sports activities automobile. Design-wise, the MX-5 will undertake sure elements of the Iconic SP idea, as this sports activities automobile will kind the idea of Mazda’s subsequent chapter in design.
Not like the Iconic SP, which may have a model that is powered by a rotary vary extender, the MX-5 will persist with its pure inside combustion engine (ICE) roots, alongside an obtainable handbook transmission. Mazda has already introduced Skyactiv-Z, its new, future engine that is due in 2027. Nonetheless, just like the Porsche 911 Carrera GTS T-Hybrid, its engine can be operating with the Lambda 1 combustion technique always. With a really perfect air-fuel ratio of 14.7:1 always and in any respect throttle hundreds, energy will naturally go down. To counteract this, Umeshita informed Highway and Monitor that they may elevate its displacement to 2.5 liters to cancel out the drop in energy figures. He says:
“However in an effort to keep away from that, now we have outlined the displacement to be 2.5 liters. So the facility is superb, and the gasoline financial system can be excellent.”

Vary Extender EVs Gaining Worldwide Traction
Whereas the MX-30 R-EV is a humble try for Mazda, the Iconic SP represents a efficiency utility for this powertrain structure. Different automakers are additionally taking discover, as a result of if there’s one market that has accepted range-extender EVs in droves, that will be none aside from China.
How A Vary Extender EV Works
Since it is a Mazda article, let’s check out the MX-30 R-EV, its first rotary range-extender EV. A single-rotor 830cc rotary engine produces 74 horsepower, and its sole responsibility is to cost the 17.8 kWh lithium-ion battery. That is labeled as a sequence hybrid, whereas Toyota and Honda use a series-parallel hybrid system with an e-CVT. A parallel system is the place the engine, transmission, and electrical motor are all related in a driveshaft, with a K0 clutch disengaging the engine from the transmission–often a conventional torque converter computerized.
A spread-extender EV is technically a plug-in hybrid electrical car (PHEV), however the terminology exists as a result of the engine by no means powers the wheels. Different PHEVs with a series-parallel or pure parallel association nonetheless let the engine immediately energy the wheels. With these methods, the engine shouldn’t be a part of the driving expertise, which suggests it may be “right-sized” in alternate for bigger batteries, extra highly effective electrical motors, or each.
What Made It In style In Latest Years
The attraction of a range-extender EV is that, when executed appropriately, it could present an excellent driving vary that may even surpass a standard “self-charging” hybrid. A spread of greater than 600 miles is the norm for these automobiles in China. Talking of which, range-extender EV gross sales there grew by 83 p.c in 2024, surpassing the expansion of EVs, plug-in hybrids, and conventional hybrids. As a consequence of China’s sheer market dimension, its urge for food for range-extender EVs has made these automobiles the fastest-growing electrified car kind worldwide.
Consequently, you now have a slew of automakers which are about to launch range-extender EVs. Probably the most outstanding one can be the closely delayed Ram 1500 Ramcharger, whereas Scout is creating range-extender EV variations of the Traveler SUV and Terra pickup to be launched by 2027. Rumors additionally counsel BMW is making ready for a range-extender EV model of the next-generation X5, marking the return of BMW’s REx powertrain for the reason that i3’s discontinuation. Now, now we have Mazda creating a rotary range-extender EV drivetrain for efficiency purposes within the case of the Iconic SP’s future manufacturing mannequin.
