#MERCEDES 2019 C-Class Driving Event Luxembourg C 300 Cabriolet Diamond White

The secret of the Mercedes-Benz C-Class's success is partly down to the wide model range, also including two sporty two-door versions: the coupé launched at the end of 2015 and the cabriolet available since the summer of 2016 address the heart and mind in equal measure. The design of the vehicles is one of the main reasons for purchasing in Europe. Both models are produced at the Mercedes-Benz Bremen plant.
Shortly after the saloon and estate, the two-door models too are benefiting from extensive revisions. The most important enhancements at a glance:
New four-cylinder engines, some of which with 48 V on-board electrical system (EQ Boost) for sporty driving pleasure with high efficiency
Advancement of the sporty design in particular at the front and tail end, new light-alloy wheels, new colours
Now standard-fit LED High Performance headlamps with new design or optional MULTIBEAM LED headlamps with ULTRA RANGE Highbeam
Enhanced interior with digital cockpit (31.2 cm/12.3 inches), larger media display (26 cm/10.25 inches), new multifunction steering wheel with touch-control buttons. Many opportunities for individualisation, e.g. through new open-pore trim elements
Lounge atmosphere thanks to ambient lighting now with 64 colours and ENERGIZING comfort control to enhance wellbeing and fitness
Additional sound system with nine loudspeakers and an output of 225 W as a new optional extra between the standard sound system and the Burmester® surround sound system
Individually configurable driving experience with new DYNAMIC BODY CONTROL suspension including damping characteristics adjustable in three stages and Sports Direct-Steer system or AIR BODY CONTROL suspension
Future-oriented driving assistance systems from Mercedes-Benz with S-Class functions and cooperative driver support
Electrification continues: C 200 with EQ Boost
A new generation of four-cylinder petrol engines (M 264) is being launched in the new C-Class. The new petrol model is coming initially as the C 200 and C 200 4MATIC with a displacement of 1.5 litres. At the same time these models are equipped with an additional 48-volt on-board network with a belt-driven starter/alternator (EQ Boost). A 2.0-litre variant will follow later.
The combination of a 48-volt on-board 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. During deceleration, the starter/alternator recuperates kinetic energy and charges the battery.
Other advantages include gliding mode with the engine switched off, and the recuperative brake with intelligent engine stop when the vehicle is coasting: recuperation only begins with overrun cut-off when braking. When the speed falls below a certain minimum level, the powertrain is decoupled and the engine is switched off. This has the advantage of maximum fuel savings through recuperation together with comfortable vehicle response.
The exhaust gas turbocharger uses a twin-scroll system. CAMTRONIC variable valve timing is also on board. This allows two-stage adjustment of the valve lift on the intake side.
In-engine measures to reduce friction round off the efficiency strategy of the new four-cylinder power unit. These include the Mercedes-Benz patented CONICSHAPE® process, known in-house as conical honing: When form-honing the cylinder walls, the cylinder wall is opened out slightly towards the bottom, so as to reduce friction at the piston skirt for lower wear and fuel consumption.
Alongside the diesel engines, the petrol engines are also equipped with a particulate filter in Europe.
State-of-the-art diesel: C 220 d
The new C 220 d opens up new efficiency dimensions and offers improved performance. The model has been certified in accordance with the latest Euro 6d-TEMP standard. In this diesel engine Mercedes-Benz uses the "step recess" combustion process - named after the shape of the combustion case in the piston. The innovations also include the combination of an aluminium engine block and steel pistons, as well as the further-improved NANOSLIDE® coating of the cylinder walls.
