Mercedes-Benz has unveiled the C-Class Plug-in-Hybrid at the 2015 Detroit Motor Show. It is the company's second vehicle to get the most advanced hybrid technology after the flagship S-Class. Being christened as the 'C 350 PLUG-IN HYBRID', it is being offered in both saloon and estate guises with the hybrid technology. The hybrid saloon could make its way in India in saloon guise, since estates or shooting brakes aren't offered in India by Mercedes-Benz. However, it would go on sale globally by mid 2016.
Following the C 300 BlueTEC HYBRID, the C 350 PLUG-IN HYBRID is the second hybrid model in the new C-Class and the second Mercedes-Benz model to feature PLUG-IN HYBRID technology. The C 350 PLUG-IN HYBRID uses the currently most advanced form of hybrid technology. Its electrical energy storage unit is a high-voltage lithium-ion battery with a total capacity of 6.2 kWh, which can be charged from an external power source and so makes an effective contribution to the low consumption and emission figures. The battery is water-cooled, weighs around 100 kilograms and is mounted in a sheet steel housing underneath the rear axle in order to maximise crash safety, driving dynamics and boot space.
Thanks to an intelligent on-board charging system, the battery can be recharged in around 1 hour 45 minutes at a wallbox or at one of the growing number of public charging points (230 V, 16 A, 3.7 kW single-phase), which in some cases offer privileged parking. Alternatively, charging via a standard domestic socket is of course also possible. Depending on the connection, a charge time of around two hours is achievable (with 230 V and 13 A, 3.0 kW). Despite the space taken up by the battery, the C 350 PLUG-IN HYBRID still has a boot capacity of 335 litres in its Saloon format and of 350 in the Estate model, or in the latter case of 1370 litres with the rear-seat backrests folded down and, as ever, a level load compartment floor. PLUG-IN HYBRID for the first time now with four-cylinder petrol engine.
In the new Mercedes-Benz C 350 PLUG-IN HYBRID, this hybrid drive concept is combined for the first time with an efficient four-cylinder petrol engine. From a displacement of just under two litres, it produces 211 bhp and maximum torque of 350 Nm. Its direct injection system with spray-guided combustion uses electronically precise controlled multiple injection and fast multi-spark ignition to deliver outstanding performance coupled with high efficiency and exemplary emissions. The electric motor of the C 350 PLUG-IN HYBRID has an output of up to 60 kW and delivers torque of 340 Nm. A total system output of 279 bhp, as well as torque of 600 Nm, are thus available to be called upon. The hybrid module of the standard 7-speed automatic transmission 7G-TRONIC PLUS incorporates both the electric motor and an additional clutch between the combustion engine and the electric motor.
