Xiaomi's sub-brand SkyNomad has officially launched with the N70 and N90 extended-range EV (EREV) crossovers. The N70 and N90's gas engine is a 1.5-liter turbocharged four-cylinder unit. Also, they’re not 100% electric, adding a 1.5-liter turbocharged gas engine that acts as a range extender. That makes Xiaomi’s latest SUVs extended-range EVs, or EREVs as they’re commonly known. The shift to longer service intervals could close the gap in affordability in running costs between EVs and EREVs.
