When the oldest car manufacturer in the world goes hybrid, you can expect the best. Indeed, they use the adage in their marketing language: “the best or nothing”. And they use it…not for nothing. This we could experience behind the wheel of a sleek E Class estate, where under the hood the well proven 2 litre 4 cylinder diesel is married in hybrid fashion to a powerful electric engine. The result is indeed the (very) best of both worlds. Impressive to say the least. Just read further…

The Mercedes engineers and strategists put their heads together and had a long hard look at what a Mercedes hybrid in today’s world has to be capable of in order to respond to the needs of its clients. It is well known that the E class sedans and estates with the good star are driven frequently at long(er) distances, and therefore the diesel engine is a (very) logical choice.
It is also a fact that this hybrid Mercedes has to be “city proof” for years to come, and therefore has to be able to drive quite reasonable distances in the city centre on lively E-power. So the choice was obvious: the well proven 2 litre four cylinder 191 HP diesel engine known from the E 220 d is also adopted here, but now alongside it is a 122 HP electric motor, which delivers more than enough zest with its 440 Nm torque.
The diesel unit doesn’t lack pulling power either, and has an impressive 400 Nm of torque. Both engines do not develop their maximum power at the same time, but nevertheless total maximum system power is not less than 302 hp and 700 Nm. You understand that this means excellent performance: your are catapulted from 0 to 100 in 5,9 seconds, and top speed is 250 km/h.
Hybrid power the Mercedes way
But the true panache of this Mercedes is the completely effortless way this performance is delivered, and the excellent comfort it offers to its inhabitants, whatever the distance travelled and the quality of the roads encountered.
A reasonable action radius in urban E driving is therefore a must, and with a 13.5 kW battery Mercedes has done what is needed to achieve this. According to the altogether realistic WLTP cycle, this E 300 de can drive on E power over a distance of about 50 km.
We did not quite achieve this with the heavier estate version, but came very close indeed. This means that in practice it is quite possible to meet even the strictest urban LEZ standards for years to come, as you can drive solely on E power.
But that is not all. With the push of a button on the central console, you can select between drive modes, and besides «E mode» and «Hybrid» you can opt for “E-save” and “Charge”.
This means you can also opt to keep the battery charged at a chosen level, or even (re)charge the battery partially or fully while driving, so that you can build up enough charge to drive later a chosen distance on electric power in the city. Very clever, this absolute versatility. On top of all that, the efficiency of the diesel engine lets you chalk up very reasonable consumption figures even during this battery (re)charging on the move, staying for instance in open road driving conditions between 6,5 and 7 litres/100 km. This is about 1l/100 km more than in non-hybrid driving, which you achieve when opting for “E-save”. Of course the hybrid mode will still improve this fuel consumption, but it costs you Kilowatts…
The fuel consumption varies evidently with the use of the plug-in function, and indeed it is in practice quite possible to use this E 300 as an urban electric car in a short distance scenario with frequent plug-in recharging. A neatly placed plug at the right side rear end of the car makes this recharging a breeze. In these driving circumstances, you hardly use the Diesel power, and therefore your fuel consumption will be very low.
CO2 Emissions are as low as 41 g/km, according to the WLTP cycle.
Creature comfort
The E class Mercedes has built itself an enviable reputation as a comfortable and spacious long distance runner, and here only superlatives are called for. The suspension is set up slightly firmer to cope with the 300 kg additional weight. Very good stability is the result, with hardly any noticeable drop in comfort levels. This E Class will still excel in ironing out those frost ridden roads…
State of the art infotainment and driving aids.
The state of the art digital instruments and panoramic infoscreen across the dashboard are now becoming a hallmark for the three starred brand, as well as the commands on the steering wheel. The host of driving aids are also setting industry standards.
Our Mercedes came with Parktronic, an excellent head-up display, 360° camera, speed limit assistant, adaptive cruise control, collision prevention assist plus, PRE-SAFE intelligent anticipation for accidents, you name it. Of course adaptive headlight beam assistant is also provided.
You are also pampered in the cabin: our test car came with the Burmester Surround sound system, Keyless Go, Easy pack electro-hydraulic rear boot lid, Premium ambiente mood lighting of the interior, a panoramic sunroof, and your eyes are spoilt in the AMG line interior with panels of open-pore ash wood and last but not least an analogue clock.The seats in Artico Leather and Dyamica black microfibre have 4-way adjustable lumbar support, and not to forget the dashboard surfaces are clad in Artico leather.
GPS and GSM antenna’s are present, Apple Car Play and Android Auto as well as inductive charging of your phone is also included.
The exterior is also adorned with an AMG line package, with a matte Disegno Selenite grey Magno paint, which suited the test car very well.
Unsurprisingly, this puts the all-in price tag of our test car well above 70.000 Euros excluding VAT, but let it be said that a standard, reasonably well equipped E 300 de Break can be had in our country for 56.700 Euro (excluding VAT) at the time of writing.
Conclusion
A very impressive hybrid, which lets you enjoy E-propulsion just where you need it, in urban traffic. On the open road, you are to enjoy the smooth and frugal Diesel power, and this is one of the good reasons you drive a car with the good star. Of course this hybrid is all the more useful and appropriate when you include a fair share of urban driving in your motoring life.
The Mercedes is a quality car built to the most exacting standards with legendary robustness and longevity, designed to move you over short or long distances in comfort and safety, and this is exactly what this break does.
On top of that, it is well styled, roomy and practical. Need we say more?
