    The MX-30 is powered by an electric motorsupported by a 35.5 kWh battery with a power output of 105 kW (141 hp; 143 PS) and 264 N⋅m (195 lbf⋅ft) torque, offering a range of 209 km (130 mi).[8] Up to 80% charge can be achieved within 30 to 40 minutes via 40 kW DC charging. With a 6.6 kW AC (1 phase, 230V, 29A) charging unit, the MX-30 is claimed to get fully recharged within 4.5 hours.[9]

    The plug-in hybrid variant drivetrain will operate in series, featuring a rotary engine that acts as a range extender to recharge the batteries, but not to power the vehicle's wheels directly.[10] In Japan, Australia and New Zealand, a gasoline powered all-wheel-drive mild hybrid version is also available. This version is powered by Mazda's 2.0 L e-Skyactiv-Gfour-cylinder engine.[11]

    This would be a fine replacement for the 2014 BMW i3-REx.

    The BEV is available now. Haven't heard anything about the range extender being released. Mazda has been talking about it for years. There have been discussions here about it. Mostly in other subforums; I remember one that started from a report on the use of hydrogen in the rotary.

    0-60 in 8.5 seconds, that's not an i3. :)

    Because of the CARB hobbling of a REx, I wouldn't get to excited if it did come to the US. Shame cause a range in the 100 to 150 miles is plenty for most, and an unobstrusive range extender would let such cars work as more than commuters when needed.

    I am curious about it, and how the EU model performs. A rotary could have some benefits over piston for a range extender.

    We will find out more about it in a few days. Friday 13th is the debut day in the EU.

    They make it easier to load and unload large cargo.

    Mazda MX-30 R-EV Brings Back the Rotary, but Not Like You Imagined

    definitely sounds like a compliance phev. Let me know if pricing and availability are better than a low production run.

    The new prius prime and rav4 primes look better in every way compared to this for the north American market. I am not sure what other markets this is really made for. I am curious on efficiency versus a similar atkinson engine - the 3 cyclinder in the yaris hybrid appears to be best in class. The small crossover gets a rather poor 92 mpge without the range extending engine.

    For more on the BEV this is based on it is a pretty bad implementation.

    The Wankel does have an advantage when the fuel is hydrogen. Mazda had made some demo PHEVs that use it.

    Not sure how you would fit hydrogen tanks in that vehicle, or where you would fuel it. I don't really believe a wankel is more efficient than a high compression atkinson engine designed for hydrogen. It definitely is less efficient than a 75 hp fuel cell.

    Can't speak on the efficiency. The Wankel's characteristics just match up better with hydrogen's for things like avoiding pre-ignition.
    Why the Rotary Engine Is Perfect for Hydrogen Fuel

    We had discussed this before, Mazda e-TPV to have Wankel dual fuel range extender | PriusChat. I don't know if Mazda actually did make an e-TPV running on hydrogen after thinking about it. The idea was at least considered in the event they needed an hydrogen car for a market.

    If think a hydrogen fueled car of any type is unlikely, but Toyota is playing with hydrogen ICEs now. Mazda might get dragged along.
