The Mazda MX-30 e-Skyactiv R-EV series plug-in hybrid has received a maximum five-star rating by Euro NCAP as the excellent results of the battery-electric MX-30 e-Skyactiv EV tested in 2020 now officially apply to its new plug-in hybrid derivative.
Both MX-30 derivatives score impressively in all four Euro NCAP test categories: Adult Occupant – 91%, Child Occupant – 87%, Vulnerable Road User (pedestrian safety) – 68% and Safety Assist – 73%.
Moreover, they achieved maximum points in lateral impact tests, as well as full marks for crash test performance based on 6- and 10-year-old children for both frontal and lateral impact.
The MX-30 was the first Mazda to achieve an overall five-star rating under the more stringent 2020 Euro NCAP crashworthiness ratings with a stronger emphasis on occupant protection, post-crash protection, and advanced driver assistance technology. This excellent performance is a result of three key factors: The latest Skyactiv Vehicle Architecture features a high-rigidity, impact-absorbing yet lightweight bodyshell. A wide range of advanced i‑Activsense safety technologies help drivers identify potential risks and reduce the likelihood of damage or injury. High standards of pedestrian protection mitigate the impact of a collision with vulnerable road users.
Having been revealed at the Brussels Motor Show in January, the Mazda MX-30 e-Skyactiv R-EV will arrive in the UK this summer A series plug-in hybrid that offers the same customer values as the pure electric Mazda MX-30, while simultaneously offering new ways of using a car as a battery electric vehicle, with its 17.8KWh battery, the R-EV has a 53-mile pure electric range, while using Mazda’s unique rotary engine technology, the all-new 830cc single-rotor petrol engine acts as a generator to enable longer distance drives without range or charging anxiety.
With no mechanical connection between the engine and the wheels, the rotary unit simply acts as a generator, ensuring the MX-30 R-EV always drives via the electric motor to deliver a seamless EV driving experience. With more than half a century of expertise in the development of rotary engines, Mazda selected the rotary powerplant for this application due to its unique ability to produce the required output from a small, light and easily packaged unit. The rotary engine is placed neatly alongside the generator and high-output motor in the engine bay. The combination of the 17.8kw battery and 50-litre fuel tank create a unique series plug-in hybrid with a flexible total range of over 373 miles, while a WLTP CO2 output of just 21g/km ensures class-leading environmental performance.
Compatibility with both AC charging and rapid DC charging is another benefit, meaning 3-phase AC charging takes around 50mins, while for maximum customer flexibility, DC rapid charging can be completed in around 25 minutes. The Mazda MX-30 R-EV has three drive-modes to suit different driving situations: Normal, EV and Charge, and thanks to a 125kw/170ps output, it delivers slightly better acceleration performance than the 145ps fully electric MX-30.
Between the launch of the Mazda Cosmo in 1967 and production of the RX-8 ending in 2012, Mazda mass-produced more than 2 million rotary engines. Adapted to meet the needs of our times the rotary engine is now back being used as a power generator rather than a drive unit. The new 8C rotary engine is a 830cc single rotor with a 120mm rotor radius and 76mm rotor width, its compact size enables coaxial placement and integration with the electric motor, decelerator and generator to achieve a unit with an overall width of less than 840mm, allowing it to fit under the bonnet without changes to the MX-30 body frame.
Thanks to the use of aluminum the engine is over 15kg lighter than the twin-rotor Renesis engine used in the RX-8. The use of direct fuel injection reduces emissions and increases fuel economy, while the engine also features an Exhaust Gas Recirculation (EGR) system to improve efficiency at low rpm and low load running. With a 50-litre fuel tank the rotary generator allows for long-distance travel without the need for regular fuel station stops.
A 17.8kwh battery was chosen to ensure a enough capacity for a 53-mile electric-only driving range while at the same time considering the environmental impact of the battery over the entire vehicle life cycle. The MX-30 R-EV’s high output 122kw/166ps electric motor can produce up to 260Nm of torque, while the new R-EV retains the same relaxed, accurate and engaging driving experience as the pure-electric MX-30.
The MX-30 e-Skyactiv R-EV features three driving modes: Normal, EV and Charge, however the choice of mode does not affect maximum vehicle speed. Normal mode delivers electric drive as long as there’s enough battery charge. If more power is required than the battery level can deliver – for example, when accelerating – the rotary engine generator will activate based on the degree of accelerator opening and supply the battery with more power. Thus the MX-30 e-Skyactiv R-EV delivers outstanding acceleration performance and ensures drivers can always enjoy the car.
Drivers can turn EV mode on when they want to stay in electric drive for as long as possible. This mode will ensure the vehicle uses electric drive exclusively until the battery is completely drained. It should, however, be noted that if the driver needs to accelerate suddenly and purposefully depresses the accelerator pedal significantly beyond a certain point (equivalent to the kickdown switch function on a standard automatic transmission vehicle), the rotary engine will activate and generate the power needed for the car to accelerate as powerfully as possible.
Charge mode can be used to safeguard the necessary amount of battery for situations such as the need to save zero emissions running for particular urban environments, additionally drivers have the option of setting the amount of battery charge they want to reserve in increments of 10%. The generator will activate when battery charge drops below the specified reserve level, charge the battery to the set level, and maintain that level of charge. Once battery charge is above the set level, the car will operate in the equivalent to Normal mode until the battery depletes to the specified level. It will then use the rotary engine generator to keep the battery at that level.
Committed to a future society free of car accidents, Mazda works continuously to advance safety performance under the Mazda Proactive Safety philosophy. The superior driving dynamics achieved as a result of Mazda’s Skyactiv Technology also contribute to the new Mazda MX-30 e-Skyactiv R-EV’s driving safety. By making the car easier to drive, they reduce the potential for accidents without compromising Mazda’s traditional fun-to-drive character.
