1. Engine performance

Let’s start where the real magic happens: under the hood!

The Mercedes E63 S and S63 aren’t just any regular cars; they’re part of Mercedes-Benz’s AMG lineup, which means they have some serious power.

Both the E63 S and the S63 are equipped with the 4.0-liter V8 biturbo engine. However, there are some small differences in their performance figures.

2. Fuel economy

With high-performance vehicles like the E63 S and S63, you might expect them to have quite an appetite for fuel.

3. Comfort

Let’s be real: no matter how powerful a car’s engine might be, it’s a deal-breaker for many if it doesn’t offer a comfortable ride.

The E63 S is designed with the spirited driver in mind. Its adaptive sports seats ensure you’re snug and supported, especially during spirited drives.

Now, the S63 is what many consider the epitome of luxury. Imagine sinking into a cloud – that’s the kind of comfort we’re talking about here.

The seats are more than just seats; they’re a full-on experience. Think of multi-contour adjustments, massage functions, and memory functions that remember just how you like to sit.

The air suspension in the S63 is like magic; floating over rough patches is like you’re gliding on air.

Ultimately, while the E63 S offers sporty comfort, the S63 is all about opulent luxury. It’s a bit like choosing between a high-end ergonomic chair and a plush, feather-filled sofa. Both are fantastic; it just depends on what kind of “sit” you’re in the mood for!

4. Dimensions and weight

Size does matter in cars, and the Mercedes-AMG E63 S and S63 prove just that.

The E63 S is more compact and lighter compared to the S63.

The E63 S is rooted in the E-Class lineup, which is traditionally more of a midsize sedan.

Its dimensions reflect a good balance between spaciousness and maneuverability. Lengthwise, it stretches to about 194.3 inches. As for its weight, the E63 S tips the scales at around 4,491 lbs.

This blend of dimensions and weight makes it nimble enough for city drives and robust enough for highway cruising.

The Mercedes-AMG S63 S-Class is larger in dimensions, spanning approximately 208.2 inches in length. And with the added size comes added weight; the S63 clocks in at around 4,564 lbs.

To boil it down, if you prefer a more nimble, easy-to-handle ride, the E63 S’s size and lighter weight might appeal to you. But if spaciousness has your priority, the S63 would be a better fit.

5. Exterior styling

Exterior styling – it’s the first thing people notice and, often, the last thing they remember.

The E63 S is like a finely tailored suit: sharp, stylish, and impeccably put together.

Its aggressive front, characterized by the large air intakes and the striking Panamericana grille, hints at the beast lurking underneath.

The side profile showcases muscular arches, especially over the rear wheels, emphasizing its sporty intentions. The rear is just as sporty with a lip spoiler, diffuser, and the signature quad exhaust tips – all signaling that this is no ordinary E-Class:

The S63, on the other hand, is pure elegance in motion. The front end is dominated by the signature Mercedes grille, flanked by intelligent LED headlights that not only illuminate the road but also add to the car’s sophisticated look.

The side profile is long and flowing, with a gentle curve that extends from the front to the rear. At the back, the S63 keeps it classy with integrated exhausts and a subtle hint of sportiness.

In short, the E63 S is for those who like a touch of aggression, a hint of racetrack DNA in their daily drive. The S63, meanwhile, whispers elegance at every curve. It’s for those who appreciate the finer things in life and who prefer subtlety over showiness.

6. Price tag

Ah, the price tag – the make-or-break factor for many decisions.

The E63 S comes with a premium price tag, as expected. Depending on the region, added options, and packages, you could be looking at a starting price in the ballpark of $110,000 to $120,000.

The S63 represents the pinnacle of Mercedes’ design and comfort ethos. Therefore, its price point is naturally loftier. The starting range for the S63 typically revolves around $160,000 to $180,000.

It’s evident that both cars command a significant investment, but they cater to slightly different audiences.

If you’re leaning towards performance and sporty aesthetics and are looking for something that can make your heart race on open roads, the E63 S offers quite a bit of bang for your buck.

On the other hand, if you’re after a car that feels like a five-star hotel on wheels and you’re willing to pay a premium for that elevated experience, the S63 is a better fit!

As we’ve broken down the nuances of each, it becomes evident that “best” is, indeed, subjective.

So, let’s approach this from different perspectives:

  1. For the adrenaline junkie: If you’re after the thrill and love the occasional push back into your seat and the roar of a powerful engine, the E63 S might be your spirit. Its performance metrics and slightly more aggressive design language make it a favorite for those looking to blend the world of luxury with that of sport.
  2. For the luxury enthusiast: If, however, you’re all about opulence, the S63 might be calling your name. From the plush interiors to the more refined exterior and the cloud-like comfort, the S63 embodies luxury in motion.
  3. For the pragmatic buyer: Let’s talk numbers for a moment. While both cars are undeniably expensive, the E63 S offers significant power and luxury for a slightly more accessible price. So, if you’re juggling performance, luxury, and budget, the E63 S might be a more balanced option.
  4. For the statement maker: There’s making an entrance, and then there’s making an entrance. The S63, with its grand dimensions and undeniably imposing presence, is for those who want to make a statement every time they arrive.
