Mercedes-Benz have updated their evergreen C-Class saloon and Estate with what Gordon Wagener, the chief design officer of the Daimler group said reflected the desire to apply “sensual purity”. It’s due for release in the northern hemisphere’s summer season.
The new C-Class will feature both forms of hybrid tech, being petrol and PHEV, and will run 48V technology. The battery alone will power the C-Class for up to 100 kilometres, the company says. The petrol engines will be four cylinders from what M-B call FAME (Family of Modular Engines). Along with turbocharging both the petrol and diesel engines the C-Class will have, M-B add in an ISG or integrated starter-generator. This provides low speed assistance using a 48 volt on-board electrical system that ensures functions such as gliding, boosting or energy recovery. Fast re-engagement has seamless switching from off to on when at lights or a stop sign.
Two engines with petrol will be available, one of 1.5L, the other of 2.0L. 125kW/250Nm for the C180, 150kW/300Nm for the C200 and C200 4MATIC from the 1.5L, with 190kW/400Nm for the C300 and C300 3MATIC versions. A pair of 2.0L diesels factor in, with 147kW/440Nm and 195kW/550Nm. Top speeds are limited at the upper end of the range to 250kph.
The plug-in hybrid C-Class will operate in all-electric mode in many cases thanks to an electric output of 95 kW (129 hp) and an all-electric range of around 100 kilometres. For many areas in Europe this could mean little to no ICE (Internal Combustion Engine) usage. The battery is an in-house design and built in a “pouch configuration” with 96 cells, with a total capacity of 25.4kWh. There is an internal cooling system fitted, managing heat discharge in any driving environment. The high density structure allows a charge rate of 30 minutes to full from empty using a 55kW charger. An 11kW charger is standard.
Energy recovery rates can be driver controlled via rocker switches in the console across all driving modes except for Sport. Lifting the foot from the accelerator has the regenerative system act like brakes, slowing the C-Class whilst simultaneously feeding back energy to the battery. Mercedes-Benz have engineered in two additional driving modes which will enable the driver to take advantage of what the powertrain offers: BATTERY HOLD: Maintaining the charge state of the high-voltage battery is given priority, e.g. when intending to drive in a city centre or green zone later on; selection of the most suitable drive configuration by the hybrid powertrain system, depending on the driving situation and route, and ELECTRIC: Electric driving up to 140 km/h, adjustable energy recovery rate in overrun mode, adaptation of Active Distance Assist DISTRONIC for electric driving, activation of the combustion engine using a pressure point of the accelerator pedal (kick-down).
Extra tech sees optional rear-axle steering with 2.5 degrees of angle reducing a turning circle to 10.5 metres. These have the rear wheels in an opposite direction in steering at speeds up to 60kph, then align with the direct front steering above 60kph. The rear steering also effectively reduces the steering ratio to 2.1 turns lock to lock, down from 2.35.
Notable changes to both the saloon and wagon have seen increase to the overall dimensions. The previous model saloon jumps from 4,686mm to 4,751mm in length, the Estate from 4,702mm to 4,751mm. Width is up by 10mm and 20mm respectively to 1,820mm each. Both share an increased wheelbase of 2,865mm, up from 2,840mm each. Luggage capacity for the Estate ranges from 490L to 1,510L, with a slightly lower load lip, and the rears eats have a 40/20/40 split for extra versatility. A powered tailgate is standard across the range.
