FRANKFURT -- Mercedes-Benz will debut a full-electric luxury sedan concept at the Frankfurt auto show
Mercedes teased the car with images on its social media account.
"The EQ story continues. We're pioneering the future of sustainable modern luxury. See the interior design vision of an all-electric four-seater luxury sedan," the automaker wrote via Twitter, describing it elsewhere as "a glimpse into the not-so-distant future."
Mercedes displayed several sketches and CGI renderings that hint toward what might be the EQS, a flagship four-door EV.
