Daimler to Show B 200 Natural Gas Drive for 2013 Sale

Daimler’s Mercedes-Benz unit is talking up its Mercedes B 200 Natural Gas Drive sedan for 2013, with a new arrangement of fuel cylinders allowing for no loss of storage space, CNG range topping 300 miles, “and around 50% lower fuel costs than a comparable petrol model.”

The Mercedes B 200 Natural Gas Drive has three CNG tanks in an ‘Energy Space’ –€“ holding the equivalent of about 31 liters of gasoline/petrol or nearly 28 liters of diesel (8.2 U.S. gallons of gasoline and 7.4 gallons of diesel) –€“ affording CNG range of better than 300 miles.

The compressed natural gas B-Class vehicle will debut at the Paris Motor Show. Mondial de l’Automobile runs September 29-October 14 at Paris Expo-Porte de Versailles.

The B 200 Natural Gas Drive’s “Energy Space” modular body consists of a partial double floor beneath the rear seat bench, affording space for one large and two smaller CNG cylinders.

“Thanks to this intelligent packaging method, the five-seater model is able to retain the generously proportioned luggage compartment for which it is known.”

They sell CNG by the kilogram in Germany, which is why ‘earthgas’ looks to be more costly than diesel or gasoline. It’ll actually take the new B200 about twice as far per euro, Mercedes says.

The three CNG tanks hold a total of 125 water liters of fuel. That’s about 21 kilograms, Mercedes says – the equivalent at Europe’s 3,000 psi/200 bar of pressure to about 31 liters of gasoline/petrol or nearly 28 liters of diesel (8.2 U.S. gallons of gasoline and 7.4 gallons of diesel).

No CNG? The car has a 12-liter (3.2-gallon) gasoline tank. “In the event that the [natural] gas tank should ever run dry, the vehicle switches over automatically, and imperceptibly, to petrol operation,” Mercedes says.

“Because drivers are not able to select petrol mode themselves, the B 200 Natural Gas Drive is taxed more favorably as a natural gas vehicle.

“The range in natural gas mode is around 500 kilometers” – about 310 miles.

The B 200 Natural Gas Drive is due to arrive at dealerships at the beginning of 2013. It will be available with manual or 7G-DCT dual clutch transmission.
