Available in the A180d model, with 114 horsepower.
While Toyota and Nissan are preparing to get rid of the diesel engine, Mercedes believes this powertrain will still be viable. The company’s smallest vehicle will be available starting in March with a 1.5-liter turbodiesel four-cylinder engine. The German model is powered by a diesel engine that is “state-of the-art”. It starts at EUR31,398 in Germany. The new codenamed “OM 608” is an evolution from the “OM 607”. It packs an additional 7 horsepower (5 kilowatts), for a total of 114 hp and 85 kW at 4,000 rpm. Many people will be curious to know how much torque is available from the diesel engine: 260 Newton-meters (192 pounds-feet) at 1,750 rpm. The A180d can sprint at 62 mph (100 km/h) in just 10.5 seconds, and reach a top speed reaching 126 mph (220 kph).
The A Class diesel engine consumes just 4.1 liters/100 km (57.3 mpg) during the combined cycle. There are corresponding CO 2 emissions of approximately 108 g/km. Mercedes claims the new diesel engine is cleaner than the predecessor. The compact exhaust-gas system, located near the engine, and complemented by high and low exhaust gas recycling, reduces nitrogen oxide emissions to levels well below the limit. The A180d is the first model to feature an SCR catalyst and AdBlue exhaust fluid.
The new OM 608 is more environmentally friendly than its predecessor. It also has a quieter engine as the sump has been covered with a polyurethane foam, while the interior foam lining covers the engine. The 1.5-liter diesel engine was developed in partnership with Renault. However, it features a number of Mercedes-specific components, including an engine mounting, dual clutch transmission (7G-DCT), two-mass flywheels, start/stop function, custom ECU, alternator, and compressor. Mercedes introduced two new diesels in its E-Class and the larger six-cylinder OM656 in their S–Class. The launch of the OM 608 follows the introduction of two more diesels in Mercedes’ E–Class . This shows that Daimler believes diesel engines will continue to be available in the future.
