- Discover in details the all-new 2024 Mazda MX-30 R-EV with Rotary Engine Generator in this presentation film.
One of the key characteristics of rotary engines makes this possible - they’re compact and don’t take up much space. Although our newly-developed rotary engine generator uses an 830 cm³ engine with a maximum output of 55 kW (74 PS) at 4,700 rpm, it is more compact than a reciprocating engine with similar output.
This is what made coaxial placement and integration of the MX-30 e-Skyactiv R-EV rotary engine with a thin, high output generator and a 125 kW (170 PS) high output motor possible. It enabled us to achieve a compact set-up that fitted in the engine bay easily and didn’t require any compromise in cabin space.
We then combined this compact drive unit with a 17.8 kW lithium-ion battery and a 50 litre petrol tank. As a result, the MX-30 e-Skyactiv R-EV not only offers an 85 km electric-only driving range for everyday needs, but also, due to an ability to generate power using the rotary engine, longer drives without range anxiety, and the same 140 km/h maximum speed as the MX-30 BEV.

Chevrolet Volt is the Roman Empire of all the plugin hybrids.
Consider this; drive to work on the battery (example: 17 miles). Drive back home in charge mode and top up the battery. That’s for someone living in a tower block who doesn’t have a charger where they park. The petrol has to be used at some point - especially in the UK with the Ethanol E5 or E10 additive that’s mandatorily added to UK petrol - E10 would deteriorate quickly if left to long in the 50 litre tank.
Savings are possible even without a home charger, but the best combination is relying on a home charger daily and then using the Rotary extender if and when the battery becomes depleted.
This vehicle should comfortably handle a 34 mile round trip commute with its 53 mile battery capacity - and even in winter when colder weather means using more battery power to warm the cabin (it uses electrically powered heat pump technology - not inefficient heated coolant from the engine); that Rotary extender should see you through the coldest European winter demands and ensure you get to your destination.
It’s no Prius - that’s perfectly clear - but it’s a very original design. Used correctly with home charging and the appropriate lifestyle, this is definitely an eco EV that will save on transport costs - especially with the correct overnight EV charging tariff from your electricity provider.
I would love this to be my next car - Mazda have a knack for creating “bespoke” vehicles that stand out - a godsend in a world of near identical euro boxes and boring SUVs.
What's your advice for avoiding fuel deterioration?
Absolutely genius in my opinion. An onboard charging station vs spending trillions of dollars to provide charging stations everywhere. Once a week charging also reduces the load on the grid. This car could be perfect for apartment or condo owners who don't have access to their own dedicated chargers.
Not to be a smart ass but I spoke about this many years ago. Smaller engines in hybrids delivering better mileage with slightly larger batteries. Imagine using a small motorcycle engine or a small diesel as a generator? Mazda has proven there's a way to not be mandated to EV cars only.
My only question is when will it come to Canada?
Isn't the Nissan E Power using the same idea? Engine as generator. And years ago, the Vauxhall Ampera/ Chevy Volt.
Honda Jazz too, although it's engine sometimes drives the wheels directly. So what's new? Just the inefficient Wankel engine I suspect
@@piglet5287 most of them haven't proven to be that efficient or popular. Sometimes theories are great but in practice perhaps not.
@@darylpreston7505 I agree with you! Will the Mazda be different?
@@piglet5287 I had an early 1980's RX7. Small engine, I think 1100cc. You're absolutely correct, they're not very efficient. That said, newer materials, improved batteries, more efficient ICE cars and a seemingly infinite combination of technologies makes this an exciting time for car owners.There is no one size fits all vehicle, especially not just EVs when a certain country produces most of the minerals and batteries for our use. Imagine if our relationship with said country soured and decided, sure you can have new batteries but they're even more $$$$? Just sayin.
@@darylpreston7505 you are echoing the head of Toyota's remarks and I don't disagree. Our authorities should legislate for low emissions but leave it to manufacturers to decide how to get there. Lugging around a huge battery has never appealed to me as an engineering solution, because having read car mags since I was nine, I know that "lightness is best" is the golden rule for making cars that drive well (and are economical).
Very interesting. Will this car ever be available in the USA with the rotary extender? I would consider buying it.
This power train would suite many. But for me the MX30 is too small and I believe that a Mazda 3 size car would have sold a lot better.
Did I hear this commentator just say 'New-kew-lar'? It's 'New-Clear'! You're not George Bush!
Yeah it's cool as a range extender, but the environmental propaganda, specially the scenes of filming this with renewal energy behind them (lol) is quite misleading.
Those Generators, even the ones in the MX-30, are incredibly inefficient, for environmental sake you would be better off it not being an ICE or Hybrid at all, and instead being purely an EV and then use the gasoline/diesel on an actual efficient industrial generator to power the grid with more electricity with the same amount of fuel than this car would consume...
EV's are the future, this coming from someone that owns an environmental unfriendly Honda Civic Type R GT.
If you really care about the environment as a manufacturer, you would focus on pushing battery tech to be even easier to recycle than it already is, make the batteries be purely out of graphene with no lithium which will happen sooner or later, and use the fossil fuels for powering the grid instead of wasting it on motorized vehicles which as mentioned above are known to be incredibly inefficient power generators with it compared to an industrial generator.
The last Mazda rotary engine was useless, used loads of fuel, oil and only lasted 70k
useless therefore essential
The 1.3L dual rotor (possibly turbo’d) Wankel Rotary Engine used in the Mazda RX-8 is a totally different propulsion unit to the 830cc single rotor unit installed as a range extender in the Mazda MX-30 R-EV.
The latter engine uses more advanced technologies and benefits from the latest research into making these engines long lasting.
This 830cc Rotary Engine is designed to be a range extender that works exclusively as a generator that charges the battery / provides extra power to the vehicle’s electric traction motor on demand (or as decided by the BMS / ECU).
This rotary engine never drives the wheels directly. Its speed is NOT governed by an accelerator cable connected to your throttle pedal.
It is set to operate within a very safe zone of no more than 4,500rpm and often marginally less than that.
Believe it or not, the often derided Prius has an Atkinson cycle engine which is governed in a similar manner, despite having a throttle pedal. If I recall correctly, the engine runs at only three (or four) specific set levels of RPMs - this is true as I presently own one.
The engine jumps between these preset operational RPMs depending on how you press the throttle pedal. For example, you’ll only get the maximum performance from the engine only if you floor the pedal - something that’s rarely done in a Prius - so RPMs seldom go over 4,500rpm in day to day use. The e-CVT transmission (actually a planetary gear set) mimics engine RPMs rising and falling through the full available spectrum like a normal vehicle with a CVT gearbox.
This is one of the reasons why those Atkinson cycle engines (on the 2nd Gen Prius for sure) are lasting at least 250,000 miles and often much more. 400,000 - 500,000 miles aren’t uncommon - but, back to the Mazda MX-30 R-EV 830cc Rotary Engine.
With its preset levels of operation, this engine is running in an optimised and unstressed regime that will virtually guarantee a long-life for the unit. There’s no turbo attached, no insane revving at 9,000rpm - at most, it’s spinning at half that speed - which research has proven to be the most optimal range of operation for that newly designed Wankel rotary generator unit.
As a range extender - it wouldn’t be constantly in operation unless the driver was extremely heavy footed or never bothered to plug the vehicle in to charge.
Under normal operation with home charging being the primary energy source of the vehicle and catering for the Monday to Friday daily commute - with longer journeys coming into play on weekends where the rotary might be pressed into service more often, and for longer, this 830cc Rotary Generator should last a great deal longer than many nay-sayers might imagine.
Indeed, 10 to 12 years at least, with proper maintenance can be easily expected - if not 15+ years.
Obviously, time will tell - but I strongly believe, based on Mazda’s history and experience, that this is likely to be the case.
Lastly, nobody seems to be aware that carefully maintained Mazda RX-7 rotary engines were known to last up to 200k miles before wearing out the rotor tips.
These were cars whose engines were NOT abused or turbocharged.
Ergo, the Mazda MX-30 R-EV Rotary Range Extended will NOT be a problem and will not suffer premature rotor tips wear - even the walls these tips move against have been sprayed with a newly developed coating to reduce tip wear further 😊
