Mercedes Benz reveals its new E-200 NGD will be available from December 2013

The automaker is adding this particularly economical and environmentally friendly variant to the E-Class family featuring bivalent drive. It uses 4.3 kg of CNG per 100 kilometers (NEDC combined), which corresponds to CO2 emissions of 116 g per kilometer. Driving 20,000 kilometers a year, the car owner can save more than 1,000 euros annually in Germany. The E 200 Natural Gas Drive will cost EUR 47,808 (including VAT).

The bivalent drive offers advantages with respect to the car's range, which is more than 400 kilometers when running on natural gas. As soon as the gas tank becomes empty, the vehicle automatically switches to run on petrol. This boosts the range of the bivalent natural gas model (the only one of its kind in the luxury segment) to more than 1,300 kilometers. With the optional 80-litre petrol tank, it can drive as far as 1,600 kilometers without stopping for petrol.

The natural gas is stored securely in three containers - one behind the rear backrest and two under the floor of the boot. Together they hold 121.5 liters (19.5 kg) of natural gas. Despite the additional gas tank, the large boot offers 400 liters of space. 

The heart of the E 200 NGD is the new four-cylinder petrol engine with spray-guided direct injection, part of the BlueDIRECT family of Mercedes Benz petrol engines. The engine generates an output of 115 kW (156 hp) and maximum torque of 270 newton meters at 1250 revolutions per minute. This allows for a highly dynamic driving performance: the vehicle manages the standard sprint from 0 to 100 km/h in 10.4 seconds, with a top speed of 220 km/h. 

In CNG mode, the car qualifies for the efficiency class A+, or B when running on petrol. In both cases, the vehicle already meets the Euro 6 standard valid from 2015.
