The Mercedes-Benz S Class Saloon PHEV
Mercedes-Benz, simply known as Mercedes, is a leading global luxury automative manufacturer based in Germany. The company is headquartered in Stuttgart and is famed for its high quality passenger vehicles, to include the Mercedes-Maybach. However, the company is also a leader in manufacturing commercial vehicles, to include the plug-in Mercedes eSprinter commercial EV and the plug-in Mercedes eVito electric van.
Mercedes-Benz EQ is the sub-brand used by the company for its portfolio of battery-electric vehicles (BEVs), plug-in hybrid electric vehicles (PHEVs) and mild hybrids. The pure electric cars are branded as EQ, while the PHEVs are branded as EQ Power. The mild hybrid vehicles are branded as EQ Boost. The PHEV portfolio includes:
- Mercedes A-Class Hatchback PHEV
- Mercedes A-Class Saloon PHEV
- Mercedes B-Class Hatchback PHEV
- Mercedes C-Class Saloon PHEV
- Mercedes C-Class Estate PHEV
- Mercedes E-Class Saloon PHEV
- Mercedes E-Class Estate PHEV
- Mercedes S-Class Saloon PHEV
- Mercedes CLA Coupé PHEV
- Mercedes CLA Shooting Brake PHEV
- Mercedes GLA SUV PHEV
- Mercedes GLC SUV PHEV
- Mercedes GLC Coupé PHEV
- Mercedes GLE SUV PHEV

The Mercedes-Benz full-size luxury S Class saloon was introduced in 1972 and is at the top end of luxury saloons in the global market. The executive saloon has sold well since its introduction and is considered a flagship vehicle for the German automotive manufacturer. The premium saloon is currently in its seventh generation. The S Class includes a plug-in hybrid electric vehicle (PHEV) variant, the S 580 e L AMG Line.
The Mercedes-Benz PHEV has a 28.6 kWh onboard EV battery, with a WLTP certified zero-emission electric range up to 103 km. Both, the EV battery size and electric range are above average, when compared to other PHEVs. In general, PHEVs have an e-range between 40 km to 50 km.
Of course, the real-world EV range will be lower, impacted by a number of factors, to include: driving style, weather, road conditions, passenger load, services used in the EV and more. Expect a real-world electric range closer to 85 km.
Nevertheless, the EV offers much scope for lowering the cost of motoring for city and motorway driving. Depending on where and when the EV is charged, the cost per km on electric mode, is between 5 cents and 10 cents i.e. far cheaper than using the internal combustion engine (ICE).
Moreover, using the electric mode, also improves the overall efficiency of the vehicle. Mercedes claims a fuel economy up to 0.6 l/100km for the PHEV. Of course, the real-world fuel economy will be lower, but far improved compared to the fuel economy of the conventional petrol variant (8.4 l/100km).
The PHEV is capable of DC charging up to 60 kW (10% – 80%: 20 mins). Not all plug-in electric cars are capable of DC fast charging. But given the price tag of the EV, DC charging compatibility is a must! Though the EV has an 11 kW onboard charger (10% – 100%: 2 hrs 15 mins), the majority of homes in Ireland will not be able to take advantage of the faster 3-phase AC charging, given that most residential premises have a single-phase power supply. A single-phase domestic EV charger like myenergi zappi, will charge the EV in under 4 hours.
As one would expect for the S Class, the interior is luxurious and technology-laden. The EV also has a number of safety features to include: active blind spot assist, active distance assist DISTRONIC, active emergency stop assist, active lane change assist etc. The interior of the PHEV is just as well specified, to include: climatised rear seats, active multicontour front seats with inflatable air chambers and massage function, MBUX augmented reality head-up display and leather upholstery.
The electric vehicle (EV) pairs 3.0-litre (6 cylinder) petrol engine with an electric motor (110 kW). The rear-wheel drive EV can achieve 0-100 km/h in 5.2 seconds and has a 250 km/h top speed (in electric mode, the top speed is 140 km/h). However, this variant is not currently available in Ireland. Currently available is the entry-level S 450 e, which can achieve 0-100 km/h in 5.9 seconds.
For those seeking luxury with lower tailpipe emissions (19g CO2/km), the S Class PHEV is well suited. Do keep in mind that driving the PHEV on the electric mode will result in zero-tailpipe emissions.
Bottom-line, electric driving is good for the environment and the wallet!
PROS | CONS |

Ireland: EV Market Overview
As is the case in a number of global markets, to include, the European Union and the United Kingdom, the sale of electric cars in Ireland is also fast gaining momentum. In 2022, a total of 23,356 new electric cars were registered in Ireland. BEVs commanded the highest market share (67.13%), between the different types of electric cars, with PHEVs commanding just over 30% market share. The majority of the plug-in hybrids registered were petrol plug-in hybrids, with only very few diesel plug-in hybrids registered.
We can expect this trend to continue, given the significant increase in electric range, affordability and choice of pure electric cars in Ireland. Top EV brands in Ireland in 2022: Volkswagen, Hyundai, Kia, BMW and Volvo. Other popular electric car brands include: Tesla, Mercedes-Benz, Nissan, Peugeot and Audi.
In January 2023, battery-electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs), accounted for over 20% of all new cars registered in Ireland. A total of 3,674 BEVs and 1,900 PHEVs were registered. The all-electric IONIQ 5 was the best-selling EV in Ireland in January 2023.
The government has set a target of 936,000 electric vehicles (EVs) by 2030, with 845,000 to be private passenger cars. This will be approximately a third of the vehicles on roads in Ireland (currently there are 2.8 million vehicles on the road). Like many other governments, Ireland is committed to ending the sale of internal combustion engine (ICE) cars by 2030.
The government is committed to the rapid adoption of electric cars in the country. The Department of Transport has committed€100 million for EV subsidies in 2022 (almost double the commitment in 2021). The grant for private electric vehicles is up to€5,000 on qualifying battery-electric vehicles (BEVs). Plug-in hybrid electric vehicles (PHEVs), do not qualify for the electric vehicle grant.
Top 5 Electric Cars (2022) | Market Share (%) |
---|---|
Volkswagen ID.4 | 12.77% |
Hyundai IONIQ 5 | 4.99% |
Tesla Model 3 | 4.47% |
Kia EV6 | 4.09% |
Volkswagen ID.3 | 3.96% |
