The Mercedes-Benz GLE 350 de SUV 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 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
- Mercedes GLE Coupé PHEV
The Mercedes-Benz GLE (formerly M-Class) premium mid-sized SUV was introduced in 1997. It is currently in its fourth generation, which was unveiled at the 2018 Paris Motor Show. The GLE PHEV SUV is only available as a diesel/electric variant.
For a start the GLE PHEV does stand out from the average plug-in hybrid electric vehicle, given the 31.2 kWh onboard EV battery. In general, most PHEVs tend to have an EV battery smaller than 15 kWh. With the larger EV battery, the GLE 350 de plug-in hybrid SUV also commands a higher EV range, in comparison to other PHEVs.
Mercedes-Benz claims the PHEV has an electric range up to 93 km (WLTP certified). Real-world range will be lower, impacted by a number of factors, to include: driving profile, braking profile, road conditions, weather conditions, passenger load etc. Either way, the electric vehicle (EV) should be able to deliver over 80 km with zero-tailpipe emissions. This should be sufficient for most urban needs and also for shorter motorway driving.
The all-wheel drive Mercedes PHEV can be charged using both AC and DC charging. The EV can be charged up to 60 kW DC (10% – 80%: 20 mins). Keep in mind that most plug-in hybrid electric vehicles (PHEVs) do not offer DC charging.
However, given the premium price tag, it is imperative that this PHEV offer fast DC charging! For AC charging, the electric car has a 7.4 kW onboard charger, allowing the EV to be charged up to 100% via a domestic single-phase EV charger in 3 hours and 30 minutes. We discourage the use of a 3-PIN domestic socket for EV charging.
We at e-zoomed recommend a ‘topping up’ approach to EV charging. This way, EV range is available to use and regular charging also improves the long-term maintenance of the onboard EV battery. Mercedes offers a 6 years or 100,000 km warranty for the EV battery.
The 100 kW electric motor is coupled with a 2.0-litre (4-cylinder) diesel engine (a petrol variant is not available). Overall performance of the Mercedes PHEV is respectable: 0-100 km/h in 6.8 seconds and a 210 km/h top speed (320 bhp/ 700 Nm).
Given the hybrid engine configuration, the plug-in SUV is more economical to drive compared to the conventional internal combustion engine (ICE) variant. Mercedes claims a fuel economy up to 0.7 l/100km. Of course, the more the vehicle is driven on the electric mode, the greater the potential for fuel economy and savings.
The EV is a good blend of luxury and practicality. The SUV can seat up to 5 adults, with ample headroom and legroom for adults seated on the rear seats (7 seater option not available). Despite the large onboard EV battery, the EV has up to 490 L cargo volume, but smaller compared to the conventional ICE variant (630 L). The PHEV is technology-packed, to include the Mercedes-Benz User Experience (MBUX) infotainment system that used Artificial Intelligence (AI) to predict the drivers behaviour and needs.
The EV has claimed tailpipe emissions up to 20g CO2/km. Again, substantially lower than the emissions of the conventional petrol variant. Bottom-line, electric driving is good for the environment and the wallet! The Mercedes-Benz electric car is not available in India.

Air Quality: The Basics
It does not matter where in India one lives, no one can escape the increased level of air pollution engulfing our villages, towns and cities, across the country. However, this is not unique to India.
Air pollution has been documented globally as one of the key issues in increased mortality rates, in particular, for those that are most vulnerable: the children and the aged. Increased air pollution has been linked to increases in premature deaths, higher rates of cancer, heart attacks, stroke and lung diseases.
In India, air quality worsens closer to more densely populated urban centres, the 1st, 2nd and 3rd tier cities. Delhi, Mumbai, Kolkata and Bengaluru are just some of the examples of cities with dangerous levels of toxic air pollution or poor air quality. In fact, air pollution levels have been so high in India in the recent years, that it has captured the attention of the world media.
Many factors affect the level of air pollution, but one that is significant, is the pollution released from road transportation, commonly referred to as ‘emissions’ or tailpipe emissions. For the majority of the globe, to include, India, emissions from petrol and diesel vehicles contribute more than 30% to air pollution. This is an average, and certainly, in more populated cities like Delhi and Mumbai, the level of toxic contribution from vehicle exhausts will be even higher. The other major contributor to air pollution is energy production and consumptions (fossil fuels).
So, what is air pollution?
- Air pollution is the release of pollutants in our atmosphere that have a negative impact on the health of individuals and the environment as a whole.
- The majority of pollutants are invisible. The are minutely small particles (finely divided solids) or gases that cannot be seen with the naked eye. These extremely small solid or liquid particles are also called particulates. Examples are: fumes, smoke, dust and soot. The majority of these particulates are less than 10 micrometres.
- Air pollution can affect the environment both outdoors and indoors. There are a number of different types of pollutants, but the most well known are particulate matter, carbon dioxide, methane, carbon monoxide, sulphur dioxide and nitrogen dioxide.
- Both carbon monoxide (CO) and nitrogen oxides (NO2), contribute to smog formation, very common in the winter months. Sulphur dioxide (SO2) contributes to haze and also acid rain formation. Particulate matters also contributes to haze and acid rain. All the above negatively impact health by increasing irritation of breathing passages, aggravation of asthma and irregular heartbeat.
- Pollutants like carbon dioxide have a far reaching consequence on our lives. It is not only air pollution that it impacts, but as being a major source of greenhouse gas, CO2 has a long-term and detrimental impact on our environment and ecosystem. More commonly refereed to as ‘climate change’.
- Most of us know in India are familiar with PM 2.5 (fine particulate matter). These are tiny particles or droplets that are two and one half microns or less in width. A micron is a unit of measurement of length equal to one millionth of a metre. An increase in levels of PM 2.5 concentrations result in an increase in unhealthy air quality, haze etc. Vehicle exhausts are a major contributor to higher levels of PM 2.5 in the air.
- Though measures like reducing traffic (odd-even system in Delhi), wearing air masks etc. can help reduce the impact of pollution, the reduction is not far-reaching. Zero-emission road transportation i.e. electric cars, are a panacea for a sustained and comprehensive improvement in air quality. The sooner, we in India, migrate to electric vehicles, the sooner can we start to improve our local air quality.
