The Mercedes-Benz S 450 e is a plug-in hybrid S-Class long saloon, not a fully electric car. Mercedes-Benz says the refreshed S-Class plug-in hybrid can travel around 100 km on electric power, while a Mercedes-Benz UK brochure lists 67–68 miles of Equivalent All-Electric Range (EAER) for the S 450 e. Those figures come from different manufacturer materials and should not be treated as a single universal specification or a guarantee of real-world range.
What is the Mercedes-Benz S 450 e?
The S 450 e is a long-wheelbase S-Class saloon with EQ Hybrid plug-in hybrid technology. In its refreshed S-Class material, Mercedes-Benz describes the plug-in hybrid as pairing an upgraded six-cylinder engine with an electric motor. It can operate on electric power, but it also has a petrol engine; it is not a battery-electric S-Class.
The available figures depend on the market and specification year. The UK brochure effective from August 2024 production gives one set of S 450 e specifications, while Mercedes-Benz’s 2026 refreshed S-Class press material describes the updated plug-in hybrid in broader terms. The two sources do not establish one launch date, launch price or globally applicable configuration.

How far can the S 450 e travel on electric power?
Mercedes-Benz says the refreshed S-Class plug-in hybrid has an electric range of around 100 km. That is a manufacturer claim, not a promise of the distance every driver will achieve.

For the UK-market S 450 e, the 2024 brochure lists 67–68 miles of Equivalent All-Electric Range (EAER). EAER is the brochure’s stated range measure; it is not interchangeable with an electric-range figure certified under a different market’s test procedure. Driving conditions and vehicle use can also affect the distance available in practice.
What are the UK brochure specifications?
These figures are for the S 450 e in the Mercedes-Benz UK brochure effective from August 2024 production, not a universal specification for every market or model year.

| Specification | UK brochure figure |
|---|---|
| Electric range | 67–68 miles EAER |
| Lithium-ion battery capacity | 21.96 kWh |
| Petrol engine output | 299 hp / 220 kW |
| Electric motor output | 150 hp / 110 kW |
These component-output figures describe the engine and motor individually; do not add them and assume the result is the vehicle’s combined system output. Mercedes-Benz’s refreshed press material separately says system output increased by up to 55 kW over the previous engine generation, a manufacturer comparison rather than an independent measurement.

| Charging setup | Stated charging time | Charge window |
|---|---|---|
| 60 kW DC public charging station | 20 minutes | 10–80% |
| 11 kW three-phase AC wallbox | 2 hours 15 minutes | 0–100% |
These are brochure figures for the specified charging conditions, not a single time that applies to every charger. Charging equipment, installation and vehicle-market configuration matter when assessing a particular setup.
Choosing an AC charging cable
Mercedes-Benz’s UK brochure recommends a Mode 3 cable for AC wallbox charging. Before buying or using a separate cable, check that its connector and current rating suit the car, wallbox and market-specific equipment. The brochure’s recommendation is not proof that any third-party cable will be compatible.

What makes the S 450 e tech-forward?
The documented technology advantage here is its plug-in hybrid drivetrain: a six-cylinder petrol engine works with an electric motor, and the battery can be recharged from external charging equipment. That combination gives the driver an electric-driving capability alongside the petrol engine. Mercedes-Benz also says the refreshed plug-in hybrid system delivers up to 55 kW more system output than the previous engine generation; that comparison and the brand’s description of a smoother, more responsive drive are manufacturer statements.

Those points support describing the S 450 e as a technology-equipped luxury hybrid, but they do not establish that it is the “ultimate” sedan or the best choice against competing cars. A meaningful comparison would need matching model years and markets, equivalent range test cycles, charging windows and power figures, along with supported evidence about cabin and comfort features.

What to check before relying on a specification
- Market and model year: Confirm the local S 450 e configuration. The UK brochure figures above are specific to its stated production context.
- Range test measure: Compare EAER only with a comparable test-cycle figure; do not treat it as equivalent to another region’s range rating.
- Charging conditions: Match the charger type, power and charge window when comparing stated times.
- Real-world use: Treat manufacturer range and charging claims as stated specifications, not independently tested outcomes.
