TOKYO — Mazda is introducing its MX-30 compact crossover in Japan as a mild hybrid first, not as the full-electric vehicle it unveiled last year at the Tokyo auto show.
Mazda also said a version of the new nameplate will be the first to get a revived rotary engine, when the company introduces it as a range-extender in 2022.
The MX-30, which went on sale Thursday in Japan, will initially get an e-Skyactiv G engine mated to a 5.1-kilowatt assist-motor and 24-volt lithium ion battery.
In Europe, where deliveries of the MX-30 started in September, the vehicle is offered only in all-electric form. That vehicle gets a 104-kilowatt motor and 355-volt battery.
EV planned
Mazda said it will introduce a full-electric MX-30 to Japan next year, but under a lease program.
The Japanese automaker said it is still weighing introduction plans of the mild-hybrid version outside Japan. Mazda is still uncommitted to a U.S. launch of either version of the MX-30, noted for its barrellike body, rounded edges, slitlike grille and doors that swing opposite each other.

Mazda said the mild hybrid's motor-assist system gives the engine a boost from a full stop, facilitates controlled braking and provides smooth power when the vehicle accelerates.
In this episode of the Ally All Ears podcast, host Emma Hancock interviews Kelly Olson, Senior Director of Operations for SmartAuction at Ally Financial, about the importance of quality control in online wholesale auctions. Olson discusses advancements in online auction platforms, highlighting the importance of detailed condition reports, AI technology for damage detection, and the evolving incorporation of electric vehicle information, all aimed at building trust and reliability for dealers purchasing pre-owned inventory.
The mild-hybrid introduction comes before the revival of Mazda’s trademark rotary engine. This year, Mazda noted a small Wankel engine was used as a range extender in a prototype Mazda 2 EV.

"A similar system could find its way onto the Mazda MX-30," Mazda said in an April statement.
At the MX-30’s Japan launch, CEO Akira Marumoto said the world would have to wait a little longer.
“As part of multi-electrification technologies, the rotary engine will be employed in Mazda’s small-segment products and be introduced into the market in the first half of 2022,” he said.
In Japan, the hybrid MX-30 starts at 2,420,000 yen ($22,900) and runs up to 3,393,500 yen ($32,100), including tax. It is available in both two-wheel-drive and all-wheel-drive layouts.
Mazda expects to sell only about 12,000 units a year in Japan.
