The Mercedes-Benz GLE 350 de Coupé 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:

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 Coupé is only available as a diesel/electric variant. The Coupé is distinctive in its exterior sportier styling compared to the standard GLE SUV. The sloping roofline adds to the appeal of the PHEV.

For a start, the GLE Coupé 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 a zero-emission electric range up to 87 km (WLTP certified). Real-world EV 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 EV should be able to deliver close to 70 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). 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.

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 GLE PHEV is respectable: 0-100 km/h in 6.9 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 pure 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, despite the sloping roofline (7 seater option not available). However, the rear-view is slightly restricted compared to the standard GLE SUV. Making use of the reversing camera will be helpful.

Despite the large onboard EV battery, the EV has up to 510 L cargo volume. 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 GLE plug-in hybrid is also well suited for company car drivers, given the low tailpipe emissions (24g CO2/km). Bottom-line, electric driving is good for the environment and the wallet!

Electric Vehicles (EVs): Jargons

There is no doubt, in that, for those new to electric driving, the terminology can be both daunting and confusing. We have chosen a few jargons to help you get more familiar with electric vehicles (EVs)! We also recommend reading our article ‘Electric Car Jargon Buster‘ for a more comprehensive list of terms.

Glossary: Electric Vehicles (EVs)
Battery-Electric Vehicle (BEV):What is a BEV? A battery-electric vehicle (BEV) is more commonly referred to as a pure electric car. A BEV is ‘pure’, in that, the vehicle only uses electric power for propulsion i.e. a BEV does not have an internal combustion engine (ICE). It is easy to recognise these zero-tailpipe emission green cars, as these vehicles are silent (except for the artificial noise), and do not have a tailpipe! 
Frunk:What is a frunk? Though a frunk is not a new term, its availability is becoming more widespread with the development of electric vehicles (EVs). A frunk is a storage space/ compartment/ trunk in the front of a vehicle, rather than the rear. In the case of pure electric cars, given that these vehicles do not have an onboard internal combustion engine (ICE), there is space for a frunk. It is worth noting that a frunk is usually much smaller than a trunk, and in EVs, a good space for storing the EV cable.
Mild Hybrid Electric Vehicles (MHEVs):What is a MHEV? Mild hybrids use both an internal combustion engine (ICE) and an electric motor. These cars are also known as ‘self-charging hybrids’. The vehicle uses regenerative braking (recuperated electric energy) to improve the fuel efficiency and to reduce tailpipe emissions (CO2 g/km). However, mild hybrids cannot be charged by an external power source, like an EV charger. 
Plug-In Hybrid Electric Vehicle (PHEV):What is a PHEV? Like a MHEV, a plug-in hybrid electric vehicle (PHEV) aims to increase the fuel efficiency and reduce tailpipe emissions. However there is much difference between a PHEV and a MHEV. A PHEV has a more powerful electric motor and a larger onboard EV battery. In a PHEV, the electric motor and onboard EV battery are also used to propel the electric vehicle. Moreover, a PHEV battery is charged by using an external power source, like a dedicated EV charger.
Regenerative Braking:What is regenerative braking? Also known as regen braking or brake recuperation, regenerative braking is a process of capturing the wasted energy (during braking) from an electric vehicle, to be reused (recycled). In the case of electric driving, the ‘captured’ energy is reused to increase the pure electric range of the EV.
