The Mercedes-Benz CLA 250 e Shooting Brake 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 CLA premium subcompact car has been manufactured since 2013. The CLA 250e plug-in hybrid electric vehicle (PHEV) was introduced in 2020. It is available as both a Coupé and Shooting Brake body style. If style is more important than space, then the CLA PHEV will not disappoint, given its sportier coupé exterior styling.
The plug-in hybrid electric car is available in two variants, with the entry level being the CLA 250 e AMG Line Premium. The PHEV has a 15.6 kWh onboard EV battery, which is an average EV battery size for the latest PHEVs. The claimed zero-tailpipe emission electric range is 68 km, which again is what we now expect from a PHEV.
Of course, there is a difference between a manufacturers (OEMs) claimed range and the real-world EV range. In general, expect to have a shorter available EV range in the real-world, impacted by a number of factors, to include: driving style, traffic and road conditions, weather, passenger load, services used onboard, etc.
In any case, the EV should be able to deliver an electric range close to 55 km, which is more than sufficient for urban driving. The EV also incorporates different regenerative braking profiles, which assists in improving the efficiency of the electric vehicle and improving the electric range. The EV does not offer DC fast charging compatibility. It has an onboard 7.4 kW AC charger.
For shorter motorway commutes, the PHEV can still deliver savings when driven on electric mode. Driving on e-mode also benefits the fuel efficiency of the EV. Mercedes claims a fuel economy up to 1.1 l/100km. Like real-world electric range, the real-world fuel economy will be less efficient than manufacturer claimed figures. Nevertheless, if the EV is driven regularly on the pure electric mode, the fuel economy will be better than the conventional combustion engine variant.
The estate EV is available only as a front-wheel drive (FWD) and the overall the performance is good. The EV combines an electric motor (75 kW) with a conventional 1.3-litre petrol engine (4-cylinder). Top speed is 235 km/h (electric mode: 140 km/h) and 0-100 km/h in 6.9 seconds. The electric car also benefits from instant torque, which enhances the acceleration of the vehicle. The EV delivers 218 bhp and 450 Nm.
The Mercedes PHEV has a high quality interior finish and is technology-filled. The EV incorporates the the Mercedes-Benz User Experience (MBUX) infotainment system that used Artificial Intelligence (AI) to predict the drivers behaviour and needs.
The EV also includes a 7.0in digital instrument cluster, a 10.25in infotainment screen with DAB radio and sat nav, heated front seats, KEYLESS-GO starting function, touchpad on centre console, Mercedes me Remote Services, ambient lighting (64 colours), smartphone integration including (Apple CarPlay/ Android Auto) and wireless charging. The electric car also incorporates: active brake assist, active lane keeping assist, cruise control with limiter, speed limit assist and attention assist.
Due to the sloping roofline, the rear-view is impacted. Also impacted is the boot space (445 L) due to the onboard EV battery. The EV has claimed tailpipe emissions up to 24g 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.

Electric Car Charging: A Snapshot
Charging an electric vehicle (EV), is really quite as simple as charging your smart mobile phone i.e. plug and play! Both, battery-electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) are charged in the same manner. Below is a brief guide to charging an electric car:
- Just like a conventional internal combustion engine (ICE) vehicle is filled with fuel, similarly, an electric car is filled with ‘fuel’, the only difference being that the fuel is electricity and not petrol or diesel. In a petrol or diesel car the fuel is stored in a fuel tank, while in an electric vehicle, like the Tesla Model Y, the electricity is stored in an EV battery, usually a lithium-ion battery.
- Electric cars can be charged at home or at public charging points. Most EV charging is done at home overnight via a dedicated EV charging station. However, some households still use a 3-PIN domestic plug to charge an EV. We strongly discourage the use of a 3-PIN domestic plug and instead encourage the installation of a high quality home EV charging station, like Webasto or EVBox.
- Pure electric cars take longer to charge than plug-in hybrid electric cars, as pure EVs have a larger EV battery. In most cases a pure electric car will have an EV battery between 30 kWh and 100 kWh, while a plug-in hybrid electric car will usually have an EV battery between 8 kWh and 15 kWh. Charging an EV at home can take between 3 to 15 hours, depending on the size of the EV battery and the type of charge point or 3-PIN plug engaged for charging. Home charging is AC charging, and in most cases up to 7.4 kW, as most homes, to include, India, are singe-phase.
Charging Times (Overview) | |
---|---|
Slow charging AC (3 kW – 3.6 kW): | 6 – 12 hours (dependent on size of EV battery & SOC) |
Fast charging AC (7 kW – 22 kW): | 3 – 8 hours (dependent on size of EV battery & SoC) |
Rapid charging AC (43 kW): | 0-80%: 20 mins to 60 mins (dependent on size of EV battery & SoC) |
Rapid charging DC (50 kW+): | 0-80%: 20 mins to 60 mins (dependent on size of EV battery & SoC) |
Ultra rapid charging DC (150 kW+): | 0-80% : 20 mins to 40 mins (dependent on size of EV battery & SoC) |
Tesla Supercharger (120 kW – 250 kW): | 0-80%: up to 25 mins (dependent on size of EV battery & SoC) |
- Public charging, to include workplace charging, is quite similar to home charging, except, the charging stations are faster and sometimes more expensive to charge per kWh. Public charging stations are both AC and DC charging, however, the AC charging is at a much faster rate (22 kW). DC charging, is the fastest way to charge an EV and depending on the EV battery size, DC charging can fully charge an EV battery in less than 40 minutes. In general, plug-in hybrid cars do not use DC charging i.e. DC charging is mostly used by pure electric cars. DC charging stations can range between 50 kW to 300 kW.
- We always encourage EV owners to carry an EV cable in the car, as not all public charging points are tethered (attached cable). We recommend the use of a 5m EV charging cable, and preferably a high visibility colour. Of course, you can buy high quality EV charging cables and EV charging stations via e-zoomed.
