Powertrain: Powerful and efficient

Sophisticated petrol and diesel engines, all equipped with ECO start/stop function, provide for spirited performance and driving pleasure. There is a choice of two ratings for the newly developed four-cylinder diesel engine. All engines are available with the 9G-TRONIC.

The new Estate is being launched with a choice of two four-cylinder petrol models – the E 200 (135 kW/184 hp) and E 250 (155 kW/211 hp) – as well as the E 220 d (143 kW/194 hp) featuring the brand new four-cylinder diesel engine. The E 200 d with an output of 110 kW (150 hp) will follow in the fourth quarter of 2016, accompanied by the E 350 d, which has a six-cylinder diesel engine developing 190 kW (258 hp), and the E 400 4MATIC powered by a six-cylinder petrol engine with an output of 245 kW (333 hp) and a torque of 480 Nm. All models will feature the new 9G‑TRONIC nine-speed automatic transmission at market launch, while the four-cylinder petrol models will also be available with a 6-speed manual transmission from spring 2017.

All engines are equipped with ECO start/stop function. The new OM 654 four-cylinder diesel engine is already designed with future RDE limits in mind.

All-new four-cylinder diesel engine: packed with innovations

The new four-cylinder diesel unit marks the birth of a new Mercedes-Benz engine family and opens up new dimensions in efficiency. It is the first passenger car diesel engine to use the stepped-bowl combustion process – named after the shape of the combustion bowl in the piston. The innovations furthermore include the combination of aluminium case and steel pistons as well as the further advanced NANOSLIDE® cylinder wall coating.

Despite having a lower displacement than its predecessor, reduced to just under two litres, and weighing around 16 percent less, the new diesel powerplant in the E 220 d has an output of 143 kW (194 hp), precisely 18 kW more than the previous engine, and delivers an NEDC combined consumption of 4.2 litres per 100 kilometres, which is equivalent to CO2 emissions of 109 grams per kilometre – a figure that until now only significantly smaller vehicles have been able to deliver. Alongside optimised airflow on the intake and exhaust sides and the use of fourth-generation common-rail injection with pressures up to 2050 bar, the fuel saving is due to a reduction in internal friction by around 25 percent. On top of all this, the engine is also more compact than its predecessor.

The E 200 d likewise equipped with the new four-cylinder diesel engine will be available from December 2016. It is rated at 110 kW (150 hp), while the fuel consumption and CO2 figures are on a par with those of the E 220 d.

The engine is already designed to meet future legislation on emissions (RDE – Real Driving Emissions). In future, exhaust gas aftertreatment systems will not only have to meet the prescribed emission limits on the test stand, but also under a wide range of real-life conditions.

All components of relevance for efficient emissions reduction are installed directly on the engine. Supported by insulation measures and improved catalyst coatings, there is no need for engine temperature management during cold starting or at low load. In addition to the advantages in terms of emissions, this results in fuel savings, especially on short journeys. Thanks to the near-engine configuration, exhaust aftertreatment has a low heat loss and optimal operating conditions.

The new engine is equipped with multi-way exhaust gas recirculation (EGR). This combines cooled high-pressure and low-pressure EGR. This makes it possible to significantly further reduce the untreated emissions from the engine across the entire engine mapping, with the centre of combustion being optimised for fuel economy.

Tried-and-trusted six-cylinder diesel engine: now even more agile

The E-Class carries over the six-cylinder diesel engine with 190 kW (258 hp) output and 620 Nm torque from the previous model series. The intercooler has been changed to an air/water system, which contributes to increased agility. The E 350 d will be available from December 2016.

The petrol engines: powerful, fast and clean

The BlueDIRECT four-cylinder petrol engines in the E-Class combine spontaneous response and high output with efficiency and low emissions. They feature third-generation direct injection with spray-guided combustion. The system pressure is up to 200 bar, the pressure being variably optimised according to the engine's mapping. Piezo injectors enable optimal mixture formation with up to five injections per power stroke.

The third-generation direct injection is supplemented by rapid multi-spark ignition (MSI). The MSI system enables up to four sparks to be discharged in succession within one millisecond, creating a plasma with a larger spatial expansion than conventional ignition.

The rapid multi-spark ignition can be controlled to vary both the timing of the sparks and the combustion period to suit the relevant operating point. This provides scope for optimising the centre of combustion and improved residual gas compatibility. This in turn reduces fuel consumption. The result of this is good utilisation of the fuel with minimum emissions.

Nine-speed automatic transmission: more comfort and efficiency

At market launch, all models come with the new 9G-TRONIC nine-speed automatic transmission. Its broad spread (9.15) of gears one to nine allows an overall reduction in engine speed a key factor for high energy efficiency and ride quality. Shortened shift and response times ensure optimum spontaneity combined with outstandingly smooth gear changes. This is combined with the transmission's high efficiency, which is a noticeable advantage in terms of fuel consumption.

The four-cylinder petrol models will also be available with a 6-speed manual transmission from spring 2017.

4MATIC all-wheel drive: traction even in difficult road conditions

The E 400 4MATIC (available from December 2016) rated at 245 kW (333 hp) features permanent all-wheel drive and benefits from improved traction and driving stability, especially in difficult road conditions. As ever, the combination of the ESP® driving dynamics control system with the 4ETS electronic traction system makes regular differential locks superfluous. This saves weight and noticeably improves handling safety as well as ride comfort.
