The Mercedes S-Class lineup is growing as the company has announced the S580e 4MATIC will arrive at U.S. dealerships later this year.

When it does, customers might be in for sticker shock as the plug-in hybrid will start at $122,550. That’s $8,050 more than the S500 4MATIC and $15,150 more than the electric EQS 450 4MATIC.

Mercedes is currently accepting orders and noted the model features a plug-in hybrid powertrain that consists of a turbocharged 3.0-liter six-cylinder engine, an electric motor, and a 21.5 kWh battery pack.  This setup enables the luxury sedan to have a combined output of 510 hp (380 kW / 517 PS) and 553 lb-ft (749 Nm) of torque.

In terms of performance, the model will scoot from 0-60 mph (0-96 km/h) in 5.1 seconds before hitting a top speed of 155 mph (250 km/h). The car’s EPA range remains to be determined, but Mercedes noted the model has a WLTP range of more than 62 miles (100 km) in Europe.

Mercedes says the S580e 4MATIC will have the “highest level of standard equipment” including an AirMatic air suspension.  Customers will also find an assortment of options including E-Active Body Control and rear seat features from the Mercedes-Maybach S-Class.  Speaking of the latter, Mercedes noted the vehicle will offer adaptive rear compartment lighting and a calf massage function to stimulate circulation as well as prevent fatigue on long trips.

We’ll learn more details closer to launch, but we wouldn’t be surprised if equipment echoes the standard S580 4MATIC.  If that’s the case, the sedan could have a 12.3-inch digital instrument cluster, a 12.8-inch infotainment system, and a 15-speaker Burmester surround sound system.  They could be joined by Nappa leather multicontour front seats with heating, ventilation, and massage functions.  Other standard equipment may include soft-close doors, power rear sunshades, and an Air Balance fragrance system.
