When you hear about class S cars, we are not just talking about a category of vehicles, but about the top of the automotive hierarchy. These are cars that combine extreme comfort, advanced technology, power and status. But what exactly is hidden behind this letter? Why are some models classified as S, but others don’t?

Many people mistakenly think that class S - this is exceptional Mercedes-Benz S-Class, but in fact this designation is used more widely. It defines a segment executive sedans and luxury cars, which are a step above even premium class models E or F. It is important to understand here: class S - this is not just a marketing ploy, but an objective classification based on dimensions, equipment and target audience.

In this article we will look at which cars belong to the class S, how they differ from other categories (for example, D or F), and what to look for if you are planning to buy such a car - be it a new one BMW 7 Series or used Audi A8.

What is class S in car classification?

In the European vehicle classification system (the so-called segment Euro Car Segment) letters indicate the dimensions and purpose of the machines. Class S - this is the highest category that unites full-size executive sedans and luxury cars with body length usually from 5 meters and a wheelbase of at least 2.9–3.1 m.

The main criteria by which a car gets into the class S:

  • 📏 Dimensions: length ≥ 5 m, width ≥ 1.9 m, wheelbase ≥ 2.9 m.
  • 💺 Comfort: multi-level sound insulation, premium finishing materials (genuine leather, wood, aluminum), ergonomic seats with massage and ventilation.
  • 🚀 Technical equipment: powerful engines (from 250–300 hp), adaptive suspensions, level driver assistance systems Level 2–3 according to SAE.
  • 💰 Price: starting cost of new models from 5–7 million rubles (in Russia) or 80–100 thousand euros (in Europe).

Important: class S does not always mean sedan. For example, Mercedes-Maybach GLS or Bentley Bentayga belong to this segment, despite the body SUV. The main thing is the level of luxury and positioning as the flagship model of the brand.

⚠️ Attention: Don't confuse the class S with class F (sports coupes, for example, Mercedes-Benz SL-Class). The latter are focused on dynamics, rather than on comfort and representativeness.

Differences between S class and other car classes

To understand why class cars S stand apart, let’s compare them with neighboring segments:

Class Examples of models Body length Target Audience Features
D (Business) BMW 5 Series, Audi A6, Mercedes E-Class 4.7–4.9 m Managers, entrepreneurs Balance of comfort and dynamics, price from 3–5 million rubles.
E (Executive) Jaguar XF, Volvo S90, Lexus GS 4.8–5.0 m Top managers, civil servants Improved sound insulation, premium options, price from 4–6 million rubles.
S (Luxury) Mercedes S-Class, BMW 7 Series, Audi A8 5.0–5.3 m Business owners, officials, celebrities Maximum comfort, unique technologies, price from 7–15 million rubles.
F (Luxury Sport) Porsche Panamera, Maserati Quattroporte 5.0–5.2 m Lovers of speed and luxury Sports dynamics + premium finishes, price from 8–20 million rubles.

Key difference between the class S — orientation towards rear passengers. For example, in Mercedes S-Class the back row is often equipped with:

  • 🪑 Separate climate control with air ionization.
  • 📺 Individual entertainment screens 10–12 inches.
  • 🍾 Refrigerator for drinks and heated/cooled cup holders.
  • 🔇 By the system Active Road Noise Cancellation (suppression of road noise through speakers).

For comparison: in the classroom E the emphasis is shifted to the driver, and the rear row is often identical in equipment to the front row.

💡

S class cars are designed as "mobile offices" - passenger comfort is more important here than handling or sportiness.

What makes and models belong to the S class?

List of cars class S small - these are flagship models of premium brands. Let's look at the key market players:

German trio: Mercedes, BMW, Audi

  • 🚗 Mercedes-Benz S-Class (including Maybach S-Class) is a segment standard, updated every 6–7 years. The latest generation (W223) debuted in 2020.
  • 🚗 BMW 7 Series (G70) - emphasis on manufacturability (for example, screen iDrive 8.5 across the entire panel) and hybrid powertrains.
  • 🚗 Audi A8 (D5) - features an aluminum body ASF and the system AI Traffic Jam Pilot (autonomy level Level 3).

Japanese and Korean brands

  • 🚗 Lexus LS - the only Japanese representative of the class S, famous for its reliability and hybrid power plant LS 500h.
  • 🚗 Genesis G90 — a Korean outsider with an aggressive design and a price lower than its European competitors (from ~6 million rubles).

British luxury and deluxe

  • 🚗 Bentley Flying Spur — manual assembly, genuine leather Mulliner, engine W12 6.0 (635 hp).
  • 🚗 Rolls-Royce Ghost — the “junior” model of the brand, but with a characteristic grille Pantheon and suicide doors Coach Doors.

An important nuance: some models (for example, Porsche Panamera) formally belong to the class F, but in terms of equipment and price they compete with S-Class.

Why are there no American brands in the S class?

American manufacturers (for example, Cadillac or Lincoln) have historically focused on the US market, where preference is given to large sedans E or pickup trucks. Models like Cadillac CT6 (discontinued in 2020) could not compete with German brands in terms of technology and status. Exception - Tesla Model S, but it is rather classified as a class E due to the electric platform and smaller dimensions.

Technical features of S class cars

Cars in this segment are not just “big sedans”. They are equipped with unique solutions that are not found even in premium crossovers. Let's look at the key technical tricks:

Power plants

  • 🔥 Engines: from 3.0 V6 turbo (340–400 hp) up to V12 6.0 biturbo (600+ hp) in Bentley or Maybach.
  • ⚡ Hybrids and electric vehicles: Mercedes S 580 e (V8 + electric motor, 500+ hp), BMW i7 (pure electric car with battery 101.7 kWh).
  • 🛢️ Transmission: only Automatic transmission 8–9 steps or e-AWD (electronic all-wheel drive).

Suspension and handling

  • 🌀 Adaptive air suspension with preliminary scanning of the road (for example, Magic Body Control in Mercedes).
  • 🎯 Rear steering (steering angle of the rear wheels up to 10° for maneuverability in the city).
  • 🛡️ Active anti-roll bars (suppresses roll in corners).

Safety and autonomy systems

  • 🤖 Autopilot Level 2–3: BMW Highway Assistant or Audi AI Traffic Jam Pilot allow you to ride hands-free at speeds up to 60 km/h.
  • 👁️ Night vision with a thermal imager (for example, in Mercedes projects images of pedestrians onto the windshield).
  • 🚨 Preventive protection: When an accident is detected, the car automatically tightens the seat belts and closes the windows.
⚠️ Attention: In Russia, many autonomous driving functions (e.g. Level 3) are not officially certified. Their activation can lead to problems with the traffic police.
