Mazda MX-30 FULL REVIEW all-new Mazda EV

[Fobroader]

I was so excited, I thought I thought this was going to be like a Bugeye Sprite version of the Miata not some lame ass battery CUV.....

[me_2]

Sorry for that, mfg tends to mix up themselves their alphabet soup and soon, all CUV (Cute Urban Vehicle) will be stamped 4 doors coupé 

I'm kidding.

I was just going by the MX, thought it was like the MX-5. Thought all their cuv things were CX.

Mazda confirms MX-30 will get a rotary engine as a range extender

I get it, it's cheaper to add a range extender than double the battery capacity. But why a rotary engine? How does its oil burning image compliment an EV?

The idea is that the rotaries are small, have high power to weight ratio(one combustion per cycle versus 2 cycles of a 4-stroke piston engine), and it's very smooth when running. This can be good for packaging and comfort reasons.

As for the fuel efficiency and emissions, remember this is a range extender, so it will run at a constant RPM and load. You can design the engine to run efficiently in that one particular region, so while it won't be as efficient as a piston engine, you won't have the case of RX-8 being as fuel efficient as Corvette despite making half the peak power and a third of the peak torque.

The only thing I am curious about is the lubrication. Rotaries have to burn oil by nature. Historically, they have burnt crankcase oil which is not clean-burning. Wonder if they use some kind of special oil that's more similar to 2-stroke oil or something like that.

^^^ I can't help but feel this rotary engine is a continuation of the MX30's quirky design and it's chosen for the car not because it's the most logical choice for it but because it can be done, like teenagers wearing jeans that have more holes in them than fabric. But I digress 
Between Mazda itself and their partnership with Toyota they have an endless assortment of tiny 4-pot engines that are reliable, fuel efficient and low on emissions. So it's almost like Mazda engineers wanted to make up challenges in order to have fun solving them. Any way, looks like it's gonna be fun

If they went that route, then it brings up the obvious question of why not just buy a Toyota...

That, and I4 isn't as smooth and it would still be bigger than a rotary engine of the same output.

I am curious to see how they combat some of the issues in rotary engines. Range extender application seems like a good testing ground.

Are they taking a page from the Tesla book? 

Lots of other automakers have used I4 and I3s as range extenders, BMW i3, Honda Clarity, Chevy Volt to name a few. I haven't heard many complaints about the NVH issues, perhaps mainly because ppl drive those cars on battery power, most of the time. I'd take reliability and fuel economy over a slightly quieter engine.

There is also the packaging advantage. The rotary guys have been calling this thing as the shoebox, because that's how big it is.

The reliability might not be too bad in the range extender usage. Rotaries most get a bad rep in reliability with the turbocharged RX-7s and RX-8(compromised for emissions). The older NA RX-7s are actually very reliable and last a good while from what I have heard.

Good conversation here.   I've seen articles on the topic of suitable gas engines for use in range extenders.

BMW went with a motor cycle engine in the i3 and a 3 cylinder Mini engine for the i8.

The use of an oil burning rotary with relatively poor emissions and requires more controls for particulates to be sold in Europe post 2025 is a strange decision.

The price of battery cells to get to 300 mile range will make efforts on range extenders moot in the next 4 years.

First Mazda MX-30 I saw on the flesh. I'm still unsure about the style / form factor, strange like, maybe not as much BMW I3 is/was but still, a 2 visible doors CUV (Cute Urban Vehicle).
160 km range (only 29 km more than my former 2014 Spark EV), its price/range ratio seem to me as weird as its proportion. To each their own I guess...

... and that version won't be sold in North-America. It's like the marketing aspects of the MX-30 were subcontracted to VW of America.

My wife just leased an MX 30 GT red today and picking it up tomorrow. I had a deposit on the range extender but won’t be getting that in Canada.
She is replacing her 2018 Volt.
I got a red 2023 CX 5 Signature to replace my Mazda 3 sport. Won’t be getting mine for a few months. More in show and shine when I get it.
