Jessica Ray: When it comes to the Mercedes-Benz S-class, it’s not so much a luxury car, as a full-on luxury experience; one that just got a whole lot more impressive with the launch of an all-new 2021 S-Class. 

Smoother sheet-metal delivers a more sophisticated look than ever; overall length is up about an inch, while a 2-inch wheelbase stretch pushes wheels closer to the corners, adding even more interior room.

And big doesn’t have to mean cumbersome, as the rear-axle steering system gives the new S-class the same turning radius as a subcompact A-class.

And as for that interior...well, we’d rather spend 10 or 12-hours in here than in any 1st-class cabin, no matter the airline. 

Greg Carloss: Of all the premium German brands, I think Mercedes offers the most welcoming and luxurious interior and alot of it starts at the S-Class before it trickles down into other models. I am a little sad the 2021 forgoes the beautiful twin-screen design. But this new center screen setup does look elegant and has proven useful for other brands."

Jessica Ray: MBUX is now available for all seating positions, and materials are more elegant looking than ever.  

Here in the U.S. we’ll have a choice of either a 450-horsepower turbo inline-6, or a 517-horsepower twin-turbo V8; both with EQ Boost electric assist.  A plug-in hybrid will arrive later. 

Of course with the S-class it’s all about the technology, and the ’21 is packed full of so much new tech, they needed a new assembly facility to build it.

Stephanie Hart: "One cool feature is the large Head Up Display with augmented reality content. When you turn it on, arrows are virtually and precisely projected onto the road."

Jessica Ray: We’ll have much more on the all-new 2021 Mercedes-Benz S-class soon. Until then, stay safe and keep it locked on MotorWeek.
