Electrification continues: C 200 with EQ Boost

A new generation of four-cylinder petrol engines is being launched in the new C-Class. At the same time these models are equipped with an additional 48 volt onboard network with a belt-driven starter/alternator (EQ Boost). The new petrol model will be launched as the C 200 and C 200 4MATIC with a displacement of 1.5 litres, with a 2.0-litre variant to follow later.

The combination of a 48 volt onboard network and EQ Boost creates the conditions for additional functions that help to reduce fuel consumption even further, while improving agility and comfort characteristics. When accelerating, EQ Boost can assist the 135 kW (184 hp) engine with an additional 10 kW (14 hp), bridging the brief moment until the turbocharger has built up its full charge pressure. This boosting is also used to reach the engine's ideal rpm as quickly as possible during gearshifts. The shift time of the automatic transmission is shortened as a result. During deceleration, the starter/alternator recuperates kinetic energy and charges the battery. The water pump is electrically driven and actuated by a characteristic map. This optimally adapts the cooling output to the current need.

Future outlook: Plug-in diesel hybrid in the C-Class

For the first time, Mercedes-Benz is uniting an externally chargeable hybrid system with a diesel engine. At the same time, the combination of the new four-cylinder OM 654 diesel engine and the latest-generation 9G-TRONIC 9-speed hybrid transmission is a special technological highlight. 90 kW of electrical output, an additional electrical torque of 440 Nm and an intended electric range of around 50 km (NEDC) will enhance the experience of locally emission-free mobility.

The planned plug-in diesel hybrid is based on the third generation of the plug‑in hybrids that had their debut at the 2017 IAA in the S-Class S 560 e (combined fuel consumption 2.1 l/100 km, combined CO₂ emissions 49 g/km, combined electrical consumption 15.5 kWh/100 km^[2]). This has a new lithium-ion battery with a capacity of 13.5 kWh. The new onboard charger increases the charging capacity from 3.6 kW to 7.2 kW, which means that the battery is fully recharged at a wallbox after approx. two hours. This should be possible within seven hours even at a domestic power socket.

The third-generation hybrid technology will support the driver with further improved, intelligent drive management. Through the extended use of data from the navigation system and information from the camera and the radar sensor, the third hybrid generation looks ahead and adapts itself to the speed and route profile. Events such as negotiating towns on the way to the destination are taken into account when planning the available electrical energy, and during recuperation and thermal conditioning of the drive components.

Apart from a serene driving experience, the hybrid technology will ensure extra comfort. This is because in addition to the drive compoinents, the high-voltage onboard electrical system also supplies the electric refrigerant compressor and the high-voltage heater booster. Both will allow pre-entry climate control of the interior not only in summer but also in winter.

La parte centrale della plancia continua ad essere oscena... 

Esce di scena il 1.6 OM626 di derivazione Renault e al suo posto c'è il nuovo OM654 (motore che ha debuttato sulla Classe E nel 2016) con cilindrata ridotta da 2.0 a 1.6.
E' dotato di due turbocompressori per una potenza di 160CV e 360Nm di coppia massima

Il 1,6 dCi rimarrà nella versione 115cv?

In tempi di rightizing/upsizing chissà perchè non hanno adottato sulla C il 2,0 depotenziato a 150cv di E?

No, anche il 115CV verrà sostituito con l'unità Mercedes

probabilmente sta cominciando a diffondersi troppo la voce del motore Renault.

Il 1.6 dCi va fuori produzione.
È stato sostituito dal 1.7 dCi

Arriva l'ibrido diesel-elettrico su Classe C, in veste 300de (berlina e wagon) e ibrido benzina-elettrico sulla C 300e (solo berlina)

Il comparto termico diesel è il 2.0 litri OM654 da 194 CV di cui non è stata dichiarata la potenza complessiva, idem per la 300e.

 

Le vetture sono tutte ibride plug-in, ma non è stato ancora dichiarato il consumo secondo WLTP.

L'autonomia in modalità solo elettrica è di 50 km e saranno presentate al Salone di Parigi il 2 Ottobre 2018 insieme all'anteprima mondiale della EQ-C
