A newly developed four-cylinder petrol engine boasting the performance of a high-capacity six-cylinder engine yet with significantly reduced fuel consumption is set to celebrate its world premiere in the E‑Class Coupé and Cabriolet. The engine generates 220 kW/299 hp from a displacement of 1991 cc and in the E 350 Coupé achieves a fuel consumption (combined) of 6.7 l/100 km (combined CO2 emissions: 149 g/km), while in the E 350 Cabriolet its fuel consumption (combined) is 6.8 l/100 km (combined CO2emissions: 154 g/km). Pioneering technologies such as the EQ-Boost starter-Generator, 48 volt on-board electrical system and a particulate filter for petrol engines contribute to enhanced environmental compatibility. The basic price for the new E 350 Coupé is 59,738 euros, and for the E 350 Cabriolet 65,212 euros (incl. VAT in each case). New highlights for individualisation are available with immediate effect: these include new paint finishes and trim parts, a Night package for the Cabriolet, plus ENERGIZING comfort control which can help to enhance the well-being and performance levels of the occupants. In addition, in future drivers will even be able to make use of specific office functions directly in the vehicle and also access important data if required – almost as if they were in their office.
High performance with the characteristics of a hybrid
The engine’s special features include twin-scroll turbochargers, belt-driven 48 V starter-alternator (EQ Boost) and electric 48 V water pump. In conjunction with the modern on-board 48 V technology, the starter-alternator enables outstanding efficiency by making hybrid functions available. In practical terms these are seen in such features as
- easy start, in which the engine starts and accelerates almost imperceptibly,
- boost – this function can support the combustion engine in the engine speed range up to 2500 rpm with additional output of up to 10 kW and 150 Nm of torque from the electric motor,
- recuperation of up to 12 kW when braking,
- operation within favourable engine characteristics,
- gliding with automatic engine switch-off when the driving conditions permit this.
Further new additions to the E-Class Coupé and Cabriolet range include the model E 220 d 4MATIC (fuel consumption (combined) for Coupé [figures for Cabriolet in square brackets]: 4.8 l/100 km [5.1 l/100 km]; combined CO2 emissions: 126 g/km [133 g/km]), plus the E 200 4MATIC (fuel consumption (combined) for Coupé [figures for Cabriolet in square brackets]: 7.0 l/100 km [7.3 l/100 km]; combined CO2 emissions: 158 g/km [164 g/km]).
