Imagine the pressure of making a new Mercedes-Benz S-Class. This car is supposed to be the peak of Everest for buyers who want a full-fat luxury car, and every successive generation should add more to the pile without forgetting its raison d’être, which means there’s a lot riding on every new model. All that hard work has paid off, though, because the 2021 Mercedes-Benz S-Class is an absolute banger, once again setting the standard for all other luxury cars.
