Mercedes-Benz hasn't made much hay with its EQ Power line of plug-in hybrid powertrains in the U.S. market, most recently lobbing batteries at the short-lived GLC 350e and the S 560e and introducing the 2024 GLE 400e 4Matic. The dual-power motivations are bigger deals in other markets, hence the introduction of the Mercedes-Maybach S 580e.
