Eco-friendly and fit for the future
The Mercedes B 200 Natural Gas Drive boasts CO2 emissions that are over 16 percent lower, markedly cleaner exhaust emissions than with petrol or diesel, and fuel costs which are some 50 percent below those of a comparable petrol-powered car.
When running on natural gas, the fuel consumption of the 115 kW (156 hp) B 200 Natural Gas Drive stands at only 4.2 kg/100 km – corresponding to CO2 emissions of 115 g per kilometre. The emission figures are thus about 16 percent lower than those of the petrol-driven B 200 BlueEFFICIENCY, which offers equivalent performance. The new model is classified as an efficiency class A vehicle and meets the EURO 6 emissions standard. But it is not only the environment that benefits – your wallet does too: If you convert the consumption of the B 200 Natural Gas Drive into the energy equivalent of petrol, the resulting price per km is about 50 percent lower than the fuel costs for covering the same distance in the petrol model.
Performance is on a similarly dynamic level: the B 200 Natural Gas Drive can reach speeds of up to 200 km/h (124 mph), and accelerates from 0 to 100 km/h (62 mph) in 9.1 seconds (with 7G-DCT automatic transmission; with six-speed manual transmission the figure is 9.2 seconds). The B 200 Natural Gas Drive operates according to the monovalent+ principle. This means that its engine generally runs on gas. For emergencies, however, there is a small 12-litre petrol tank on board. In the event that the gas tank should ever run dry, the vehicle switches automatically, and imperceptibly, to petrol operation. As the driver is not able to select petrol mode himself/herself, the B 200 Natural Gas Drive is taxed more favourably as a natural gas vehicle. The range in natural gas mode is around 500 kilometres (311 miles).
The trip computer menu in the instrument cluster has been extended in the case of the B 200 Natural Gas Drive: the respective operating mode is displayed. In addition, a fill level indicator and remaining range are included for petrol mode. In gas mode, the driver has access to all of the regular trip computer functions.
Vehicles fitted with natural gas drive are not only particularly environmentally friendly, they are also sustainable. This is because in addition to mineral natural gas, they can also be operated using biogas. Even synthetically produced gas can be used: this is produced using “excess” energy from solar power plants or wind farms, and in the future could help to resolve the storage problems encountered with alternative power generation. In this respect, taken overall, the B 200 Natural Gas Drive can be considered to be emission-free.
Thanks to the “ENERGY SPACE” modular concept, the B-Class was designed from the start with the need to accommodate alternative drive systems in mind: various interface points in the bodyshell make it possible to modify the main floor for the versions with alternative drive and to exploit use of a partial double floor beneath the rear bench seat.
This underfloor area houses one large and two smaller natural gas tanks. Due to this intelligent packaging method, the five-seater model has been able to retain the generously proportioned luggage compartment for which it is known.
In order to accommodate the natural gas tanks in the underfloor area, the suspension has been specially adapted and raised compared with the B-Class models with combustion engine – in the case of the B-Class Natural Gas Drive by 37 mm both front and rear.
The B-Class Natural Gas Drive is produced as part of a coordinated production system between the competence centre for emission-free mobility at the Mannheim plant and the Rastatt plant. The gas system with petrol tank, exhaust system, heat shields and all the relevant electric systems, is produced at the Mannheim plant and supplied as a complete module to Rastatt. Production of the bodyshell, including complete assembly of the B 200 Natural Gas Drive, takes place at the Rastatt plant.
Separation of the production processes in this way ensures that responsibility for the natural gas-related elements rests completely with the competence centre for emission-free mobility at the Mannheim plant. The Rastatt plant remains responsible for all petrol engine-related aspects. The final, coordinated handover of the B 200 Natural Gas Drive to the Sales and Marketing division in readiness for delivery to the customer takes place at the Mannheim plant.
