We drove the Mercedes GLC 400e  4MATIC: a plug-in hybrid with the luxury and panache of the good star… – Autoprova – for the Connaisseur

Mercedes is an expert in designing and building premium lifestyle cars, and has with its new GLC Coupé a new and strong contender in this segment. The Coupé version is a more sporty and stylish looking variation on the GLC SUV, which is indeed one of its absolute bestsellers. This Mercedes combines good proportions with stylish surfaces and, certainly in the AMG Line version we tested, a beautiful interior. Mercedes says when stepping into its cars, it feels like coming home. We can only agree. All this is combined with state of the art plug-in technology. Just read further…

Indeed, the Mercedes GLC looks good, albeit the overall silhouette of these bigger SUV Coupés are a bit chunky. The AMG Line version we drove The AMG Line is available with 19-inch or 20-inch mixed-profile tyres and wheel arch liners in the vehicle color. Also offered as optional extras are easy-entry running boards and last but not least a so-called “Night package.”

The interior is a chapter on its own…

Indeed it is… The color of the seats and upholstered panels was very well matched to the exterior, and indeed the generous trim area flows seamlessly into the curved centre console. Standard for the AMG line is the leather-lined dashboard with nappa-look beltlines, and it is a pleasure to see and touch. Some trim elements have innovative surfaces. In our test car, these included interpretations of open-pored wood veneers in brown, with aluminum inlays.

Of course, we find a further improved MBUX operating system in front of us. . The 12.3-inch (31.2 cm) LCD screen in front of the driver appears to float freely above the trim surface. The 11.9-inch (30.2 cm) portrait format central display rises from the centre console and likewise seems detached from the trim surface. Like the dashboard, the screen surface is slightly angled towards the driver, which makes it a bit awkward for the front passenger to imput commands on the screen and seeing the resulting information…There is a special tactile slider command for the sound volume, which reacts indeed more positively and faithfully to your finger input.

A new feature which we liked aesthetically is the floating control cluster, into which the door opener and seat adjustment controls are integrated.

Driving: enjoying workmanship and efficient performance…

There is something unique about driving a Mercedes. It is the feeling of solidity, absolute workmanship, enhanced by the opulence of the interior and the experience of an ultra solid bodywork and chassis. A Mercedes will never really invite you to throw it around corners but nevertheless lets you feel its sheer power and high performance capability. You feel indeed that it is fully ready to do great things, but it will rather invite you into a sedate and responsible driving style. Of course it has the performance.

We tested the 400e, which is the plug-in hybrid version with a 2 litre petrol engine, delivering not less than 185 kW/252 hp at 5,800 rpm and 400 Nm of torque between 2,000-3,200 rpm. But that’s not all. It is assisted by a 100 kW electric motor delivering also 440 Nm of torque. You understand that this makes for effortless, instant accelerations. This Mercedes will catapult you from 0 to 100 km/h in 5,6 seconds, and the top speed is also almost in supercar league with a good 239 km/h. Total system power by the way is 280 kW/381 hp, and total system torque not less than 650 Nm.

But don’t expect a nervous supercar when you are driving it in town. The 100 kW electric motor will take most of the honors, and drive you whisper smooth over the city boulevards. If you choose the hybrid driving mode, it will in default configuration (you can select another configuration of course) run on battery first, until it is depleted, and this especially in urban driving conditions. According to the WLTP test cycle, the electric range varies between 119-131 kilometers. But you can also choose to hold the battery charge constant for later use, and then there is also the obligatory sport mode. You can also choose for instance the electric “all-terrain” mode, the choice is yours…indeed, it is a 4MATIC…

The battery has a rated capacity of 31.2 kWh, and is an in-house development by Mercedes-Benz. . Starting from empty, a full recharge with the optional 60 kW DC charger is completed in around 30 minutes. The GLC Coupé is equipped as standard with an 11 kW three-phase AC charger.

The full electric power is available up to 140 km/h. It should also be noted that in the new GLC Coupé, Mercedes-Benz uses a so called “electromechanical brake booster”. It automatically controls the flexible transition between hydraulic braking and recuperation, depending on the driving situation, to ensure optimal energy recovery and braking performance at all times. Indeed, we noticed that even in the “battery hold” position, after we braked almost to a standstill, we then drove for a few hundred meters on battery power when we continued our route, just based on the electric energy we recuperated during the previous braking.

Excellent agility and comfort The GLC Coupé is also surprisingly agile. It has a new four-link front suspension and a multi-link independent rear suspension mounted to a subframe. The hybrids have air suspension and level control at the rear axle as standard too. On request the new GLC Coupé is available with the so-called “Tech Package.” This includes the AIRMATIC air suspension system and active rear-axle steering with a 4.5° steering angle. A very positive handling is the result. The steering has a variable ratio as standard, and this also helps to give you the impression of steering a smaller car. Of course, comfort is paramount in this GLC.

The optional ENERGIZING Plus package brings them to life at the touch of a button or by voice command and bundles them in up to seven comfort programmes. At the same time, the system creates a matching atmosphere in the interior - e.g. invigorating in case of fatigue or relaxing in case of an elevated stress level. The ENERGIZING COACH suggests an appropriate fitness or wellness programme based on vehicle and trip data… need we say more? We can only say that the seats are excellent fore and aft, and that indeed long trips are restful in this Mercedes. Of course the GLC offers excellent stability on motorways and open roads, with very little road or wind noise reaching the cabin.

Another novelty with the GLC Coupé: there is a trailer menu and towing route planner for navigation: In the central display, routes can be planned that are suitable for driving with the previously defined trailer. This takes into account permitted widths and heights along the route, among other aspects.

Efficient

Plug-in hybrids have a varied consumption pattern, largely depending on how you use it. WLTP figures for combined fuel consumption are 0.6-0.5 l/100 km, with weighted combined power consumption being 22.4-20.2 kWh/100 km. We noted that when cruising in the “battery hold” function between 110-120 km on the open road, that the excellent aerodynamics of the GLC resulted in a consumption of… 5,7 l/100 km.

Practical

The GLC has of course all the thinkable infotainment on board, and we also enjoyed the masterful Burmester® surround sound system, offering 15 premium speakers and a total output of 710 watts. With even more boot volume than before, the GLC Coupé offers 390-1,335 litres in plug-in hybrid form. The EASY-PACK tailgate is standard. This opens or closes at the touch of a button using the ignition key, the switch in the driver’s door or the unlocking handle on the tailgate.

Standard equipment of the new GLC Coupé already includes the AVANTGARDE Line, among other features. This includes large displays, smartphone integration, wireless phone charging and heated seats for drivers and passengers.

The new GLC Coupé has LED High Performance headlamps as standard. DIGITAL LIGHT is available as an optional extra. The light is created by a matrix of LEDs in the headlight unit that can be individually controlled.

Conclusion

This stylish premium SUV in the plug-in hybrid form as we tested here for you marries the best of all worlds. It gives you the pleasant “Zen” feeling of E-driving, with the range and long distance performance of a conventional IC engined supercar. All this in utter quietness and comfort, combined with sleek styling, a cabin which is a pleasure to look at and touch, with an opulent and tasteful interior and instrumentation which makes you indeed feel utterly at home. It offers all the room and space you want, is at home on any road, and even off the road too. Last but not least, it is even a very practical and sturdy towing car. Last but not least, it is future proof with its 140 km E-range… so a car to have and cherish indeed…
