The only manufacturer to propose the combination of diesel and the rechargeable electricity, Mercedes has made a technical and strategic choice, which is giving excellent results, especially in the company fleet sector. Thanks to contained consumption, electric autonomy of up to 122 km and a significant reduction in management costs, a very advantageous solution is revealed compared to petrol alternatives

In the large crossroads of the energy transition, between increasingly stringent regulations and the urgency to contain management costs, Mercedes has cut out a leading role in the company fleet sector. The secret? A technology that no other manufacturer in the world wanted to or know how to bring to the market: Diesel Plug-in Hybrid. An apparently countercurrent combination, but in the facts winning. And to testify it is not only the sales data, but also the growing appreciation of a clientele more and more attentive to the TCO. Acronym for Total Cost of Ownership, represents the total cost of possession of a vehicle e It includes not only the purchase price, but also management, fuel, maintenance, insurance and residual value costs. In other words, it is the most realistic indicator to evaluate the overall economic convenience of a car over time.

The Mercedes recipe

In a world that has suddenly turned his back on the diesel, Mercedes has chosen a different road: electrify the diesel engine, combining it with the plug-in hybrid traction. A courageous and at the same time rational choice, especially for those who grind kilometers every day. The heart of this proposal is the 300 de engine, a unit that Equips nine models of the range: from the class C and E SE seats (also station wagon and all-termin), to the GLC and GLE SUVs, also proposed in the SUV coupe version. A complex technical architecture, which It combines a 197 HP four -cylinder 2.0 turbodiesel with a 136 HP electric motorfor a total power of 333 HP and a couple monstrous of 750 nm. Remarkable performances, which translate into a 0-100 km/h in 6.4 seconds and, above all, in Record consumption: less than 2 liters per 100 km in the mixed cycle And just 17 g/km of Co₂ according to the WLTP cycle.

important autonomy

Among the technical advantages of the GLC 300 de stands out autonomy in 100% electric mode, which can reach up to 122 kmthanks to a generous 31.2 kWh battery. A value that allows you to cover almost all of daily travel to zero emissions. The charging system supports powers up to 11 kW in AC (alternating current) and 60 kW in DC (continuous current), ensuring good operational flexibility. 4Matic all-wheel drive and the 9G-Tronic automatic transmission complete a technical package Designed to offer comfort, safety and fluidity, in the city as in long transfers.

also for private individuals

But the 300 de Motorization is also conquering private customers, especially those most attentive to their driving style and the real use of the electric component. According to Mercedes study, private customers travel on average 50 percent of the kilometers in electric mode, against 11 percent of business customers. A sign that, used in the correct way, this technology is able to drastically reduce costs and environmental impact. In 2024 in Italy they were Set up about 52,000 plug-in Hybrid cars, a lower figure even to full electric. Yet Mercedes recorded, in the long -term rental channel, a Phev share equal to 18 percent, which in the first quarter 2025 rose to 24 percent. A result that testifies to the effectiveness of the Diesel Plug-in proposal in the company context.

Comfort and technology

Inside, the interior of the GLC reflects all the Mercedes style in terms of materials, constructive care and innovation. The dashboard houses two large displays: the 12.3 -inch tools and the screen infotainment 11.9 inches arranged vertically, managed by the Mbux system with advanced voice commands and customizable functionality. Touch controls on the steering wheel, the environmental lighting system and the availability of ergonomic and heated seats complete an environment designed for daily comfort. The space is not lacking too: 470 liters of load capacity in standard configuration, which become 1,680 by breaking down the rear sofa.

accounts in your pocket

The GLC Diesel Plug-in is today the reference model for the Business channel: eight out of ten customers in the world of fleets prefer this engine compared to the Phev petrol alternatives, that is to say the rechargeable hybrids. A choice not only of performance, but also (and above all) economic. The simulations conducted by Mercedes-Benz Lease demonstrate how, With the same model, the Diesel Plug-in version guarantees saving up to 20 percent On the TCO compared to the plug-in petrol variant, with peaks of 30 percent in the case of the GLE. That’s why, Despite an initial list higher than about 10 percentthe choice of plug-in diesel is more advantageous in the long run. The reason? Diesel consumes less, especially when the battery charge ends, while petrol return to much higher consumption levels.
