Mercedes’ new full-size sedan, dubbed EQ S, will be part of the Daimler unit’s push to introduce 10 all-electric vehicles by 2022, CEO Dieter Zetsche said. The EQ line will be flanked by plug-in hybrid models offering a “totally different” battery range. While conventional vehicles will feature mild hybrids with 48-volt technology. Mercedes, the world’s best-selling luxury-car maker, had record deliveries and profit last year as it defended the global top spot against BMW AG’s namesake brand and Volkswagen AG’s Audi marque.
