Mercedes-Benz is ready to start a new electric era with its newly minted EQ sub-brand. At the top of the EQ lineup sits the 2022 Mercedes-Benz EQS Sedan, the S-Class of luxury electric vehicles. Mercedes just passed a major milestone with EQS production starting at Factory 56 in the Sindelfingen plant. This is the same factory where the gas-powered S-Class and Maybach S-Class are produced.
