Fast-building its EQ family, Mercedes-Benz brings all-electric power to the flagship of the brand: the S-Class. After months of teasing, it has finally given the all-new EQS a proper world premiere. The electric sedan explores the highest echelons of the electric market with a range that pushes 500 miles, a sleek, slippery design that Mercedes defines as the world’s most aerodynamic, and more tech than some Silicon Valley zip codes.
The EQS becomes the latest step in Mercedes’ Ambition 2039 plan that aims to create a fully carbon-neutral new car fleet within two decades. The car follows the EQC crossover, EQV van and EQA hatchback Mercedes-EQ introduced previously, and takes its place at the top of the EQ family. Mercedes intends for plug-in vehicles to push their way to over half its sales by as early as 2030, and the EQS makes some strong arguments certain to wrest sales from the ICE side … at least for those shopping the high end of the luxury sedan market.
The US-market EQS 450+ base model comes with a 329-hp (245-kW) rear-axle electric drive. Those looking for more power and performance will be able to step up to the EQS 580 4Matic, which adds a front-axle electric drive for a total of 516 hp (385 kW) of all-wheel drive power. The 450+ sprints from 0 to 60 mph (96.5 km/h) in 5.5 seconds, while the more powerful 580 cuts that to 4.1 seconds. Both cars have their speeds limited to 130 mph (209 km/h). Mercedes also plans to raise the stakes with a 630-hp (470-kW) performance variant in the future.
A combination of carefully optimized factors and features helps the EQS travel up to an estimated 478 miles (770 km) on the WLTP cycle. Most notably, the new scalable high-density battery family tops out a hair under 108 kWh for the EQS, packing roughly 26 percent more capacity than the EQC battery. A smaller 90-kWh battery will also be used in the EQS line. Mercedes plans to stamp each battery with the promise of 70 percent capacity by the 10-year or 155,000-mile (250,000-km) mark. Over-the-air (OTA) updates will keep the energy management system evolving and performing at optimal levels.
