Mercedes details all-aluminum 2.0-liter diesel for E 220d

Mercedes has released a more in-depth description of its newly developed turbodiesel 2.0-liter four-cylinder engine powering the E 220d.

 

It’s the first all-aluminum four-cylinder diesel engine from Mercedes and manages to be around 13% more economical than the previous 2.1-liter unit. Displacement has been reduced to two liters and weight is down from 447 lbs (202.8 kilograms) to 371.2 lbs (168.4 kg) in a more compact size.

 

Aside from being more frugal and refined, the 2.0-liter unit is also more powerful as output has increased from the 2.1-liter’s 168 horsepower (125 kilowatts) to 192 hp (143 kW) at 3,800 rpm. The maximum torque of 295 pound-feet (400 newton meters) is delivered through the nine-speed automatic transmission from 1,600 rpm to 2,800 rpm.

 

In E 220d guise, the 2016 Mercedes E Class will cover the sprint to 62 miles (100 kilometers) per hour in 7.3 seconds before topping out at 149 mph (240 kph). As for fuel consumption, it needs 4.7 - 4.3 liters / 100 km in the city, 4.1 - 3.6 liters on the highway, and 4.3 - 3.9 liters in the combined cycle, with CO2 emissions varying between 112 to 102 g/km.

 

The E Class equipped with the OM 654 engine is slated to go on sale this spring and will kick off at €47,124 in Germany.
