Mercedes-Benz S-Class (2025): Powertrain & Real-World Utility
The 2025 Mercedes-Benz S-Class Plug-in Hybrid features a 28.6 kWh traction battery delivering an official WLTP electric range of 77 km, paired with a 510 HP powertrain producing 41 g/km CO₂ and 1.8 L/100km fuel consumption and 7.2 kW AC charging.
Battery Pack vs Market
28.6 kWh gross
Equipped with a large 28.6 kWh pack, the S-Class sits in the upper percentile of European plug-in hybrids, offering true zero-emission range that rivals dedicated urban EVs.
Real-World Range Expectation
While official WLTP laboratory figures state 77 km, drivers should anticipate approximately ~71 km in temperate urban commutes, and around ~49 km during sub-zero motorway trips with cabin heating.
Charging Infrastructure
7.2 kW AC Onboard
A standard 11/22 kW home wallbox will replenish the pack in approximately ~3.6 hours. Fast DC charging is not equipped on this model, meaning charging is best suited for overnight domestic wallboxes or workplace destination chargers.
| Specification | Official Homologated Value | European Segment Context |
|---|---|---|
| WLTP Electric Range | 77 km | Above Average |
| Battery Capacity | 28.6 kWh gross | Ultra High-Capacity PHEV |
| Total System Power | 510 HP | High Performance |
| Charging Capabilities | 7.2 kW AC (AC Only) | Domestic / Workplace AC |
| CO₂ Emissions & Fuel Consumption | 41 g/km • 1.8 L/100km | Euro 6e-bis Compliant |
Daily Commute & Efficiency Verdict: For European motorists with typical round-trip daily commutes of ~30–40 km, the Mercedes-Benz S-Class's 77 km electric range can comfortably cover ~2.3 days of routine driving on pure electricity before triggering the combustion engine.
Euro 6e-bis & Corporate Fleet Impact: With an official rating of 41 g/km CO₂ and 1.8 L/100km fuel consumption, this vehicle benefits from competitive tax brackets across major European markets. Under revised 2026/2027 Euro 6e-bis Utility Factor calculations, high electric range models like this retain substantially lower Benefit-in-Kind (BiK) and company car tax liabilities compared to older generation PHEVs.
Euro 6e-bis & Company Car (BiK) Tax Impact
With 77 km electric range and 41 g/km CO₂, this model qualifies for an estimated UK BiK rate of 5% (Low). Shorter range PHEVs face stricter testing utility factors under 2026/2027 fleet rules.
