Rotary-equipped Mazda MX-30 R-EV introduced

Mazda's preference for doing things differently has delivered a plug-in hybrid that doesn't need plugging in


Mazda can always be relied on to do things a little differently, and confirmation of the MX-30 e-Skyactiv R-EV’s spec is further proof of that. It combines a 17.8kWh battery, an 830cc single rotor rotary engine and a 166hp electric motor to create a series plug-in hybrid like no other. Don’t forget the freestyle doors like an RX-8, too…

The new rotary engine is more than 15kg lighter than the twin-rotor used in the old coupe, with technology like direct fuel injection to improve fuel economy and an exhaust gas recirculation valve that will boost efficiency at low load running. Perhaps most relevant for this application, the motor is absolutely tiny. With a 120mm radius and 76mm width for the rotor, it can be incorporated with the electric motor under the bonnet in a package less than 840mm wide. Consequently, no changes have been made from the pure electric MX-30 body to incorporate the range extender powertrain.

The rotary unit only ever serves as a generator for the electric motor, much as the 650cc bike engine did in the old BMW i3 REx. Its 50-litre fuel tank means a theoretical range of more than 400 miles, way ahead of the 124 miles of the standard car. In its pure electric mode, the R-EV has a 53-mile range, and overall CO2 is rated at 21g/km. The battery can be charged via AC or DC charging, with a best-case rapid charge of a full battery taking 25 minutes.

Though slightly up on power against the 145hp MX-30 EV, the new model has a little less torque (192lb ft against 200) and while we await a kerbweight figure, we expect comparable performance from the R-EV - meaning 0-62mph in 9.7 seconds, and a top speed of 87mph.

There are Normal, EV and Charge drive modes for the e-Skyactiv R-EV. The first keeps the MX-30 electric as much as possible, though can wake the engine up if there’s a call for more battery power; EV will only use electric until it absolutely can’t; and Charge will keep a set amount of juice in the battery (the driver can choose the amount) if, say, there’s a zero-emission zone at the end of the journey.

In the UK, specs for the R-EV will mirror those already in place, with both the Prime Line (£31,250) and Exclusive Line (£33,150) priced identically to the BEV model. The Makoto is £450 more than the battery-powered car, at £36,000. Mazda UK will also be receiving 400 examples of the Edition R, which sounds like a souped-up RX-7 from the early 2000s, with Jet Black paint and Maroon Rouge accents that pay homage to the old R360. There are rotary symbols everywhere, too, from the headrests to the key, and - get this - the mats feature both the symbol and a single stitched white line of 2.6mm. Because the rotor apex seal grooves are 2.6mm wide. God bless you, Mazda - that sort of touch must be worth £37,950 on its own. The MX-30 e-Skyactiv R-EV is on sale now, with the first cars due in the UK this summer.

What's the mpg when running on the wankel? The electric London Taxi manages about 35 mpg.

Dare I say reasonably priced with a few cunning design touches, quite interesting.

Unfortunately my local dealer is a bit of an arse, so won't be buying another Mazda.

53 mile electric only range is disappointing, it'll be a what, 40 mile range at this time of year at best? I know most only do short commutes but 40 mile isn't enough, I'd say 60 is a stretch in reality.

Close but no cigar.

Well if it has a 50 litre tank and a 400 mile theoretical range with 53 miles of electric only (I assume that figure is empty to full of both the fuel tank and the battery), that implies that 50 litres of fuel gets you 350ish miles, which makes 32mpg.

Is this classed for BIK as EV or a Hybrid?

It really does depend on your use case. For our family car, the longest regular trip it does is about 15 miles each way so a 53 mile range would be plenty for 99% of our journeys. We'd only need to use the ICE maybe once a month for irregular trips further afield.

Well done Mazda. That's a fantastic price point and should be bang on for the target market of advanced years folk who pop to town once a week but are worried about range anxiety in EV cars.

I personally wish 'Hybrid' cars all came with a minimum 100mile full electric range. My i3S REX manages 90-125 depending on winter or summer and driving style, I can mostly use it as an electric car, but I still find myself relying on the REX engine perhaps one in ten drives. If the range was 35-60miles then electric running would be in the gimic range for me rather than practical.

Thanks for being gentle beer as it's written in second line of headline, can only get EV via work scheme and was hoping this would fit hence selective skim reading >.<

Top speed of 87 mph ?? So on a motorway it is running near to flat out ? Would you really get a 400 mile range like that ?

I'm pretty certain that it will be an electrical limitation and not mechanical. You don't think it will be configured to run at flat out power and rpm at 87 mph do you?



Rotary engines are pretty good under sustained higher loads, their fuel consumption and emissions are no worse than a piston equivalent. Their downsides occur when they are throttled back and run are partial loads.

I know, as soon as I typed it I knew it was open for discussion and if it was sixty someone would need eighty! I do think it's on the tight side for europeans who don't live in cities however.

There are full EVs that struggle to do 100 miles (looking at you e-Mini)

This to me offers a really good compromise of a useful electric range that would cover most of our journeys, together with proper long range usability.

Great price too vs the mad money being asked for run-of-the-mill EVs, I could really imagine owning/renting one of these via a company scheme.

Some interior pics in the article would be good, for the terminally lazy like me.

Better than expected to be honest. I'd like to know how realistic that range is at motorway speeds, if true then that's a really nice balance between EV and ICE.

Price is decent too.

I assume that in normal hybrid mode the rotary engine is running wherever possible to avoid use of the normal engine. It can't be a "real" 33mpg or 400 mile range even on a long run, that would seem a huge disappointment.

I wonder what proportion of ev's are company cars? I was basically forced into one because of bik, but with these plug-in hybrids it's a different bracket and not worth it

It doesn't have a 'normal' engine. Its Electric, or assisted by the rotary by way of it generating electricity.

Seems like it's economy figure is low if you're always doing long journeys and the rotary is always running, but I assume the car is aimed at people doing short journeys during the week with the odd long trip a few times a month. In that case that mpg figure is less of an issue, as you're saving so much during the week.

If you're doing long trips every day, then you want a modern petrol that does 40-50mpg on a run, or a full on EV with a big battery (assuming everyone is avoiding diesels as a new car proposition). This Mazda wouldn't suit my needs as I have a 110mile round trip commute, but I do think it strikes a very good balance for people who work in the same city they live in. I wish I did.

Interesting, different, doesn’t weigh 3 tons, pretty cheap, not so fast as such - but hey, variety in an otherwise pretty bland world!

Thumbs up Mazda!

Ah, I misread the description slightly about the second engine. In any case, the Vauxhall Ampera with fairly similar specs was 2.1 tonnes with a 35 litre tank and it managed 58mpg:

https://www.greencarguide.co.uk/car-reviews-and-ro...

"After a week and 711 miles in the Ampera, much of it on motorways, we averaged 57.7mpg – which is impressive for such a highly refined car with good performance. On average the car had an electric range of between 35 and 37 miles after recharging.

If you drive the Ampera on its petrol generator, you can expect somewhere between 40-50mpg."

This Mazda is 1778kg. So I think there is something off with the estimated 33mpg figure.
