Economical gas

Economical gas

Drivers can currently enjoy low fuel prices. Alternative drives have therefore slipped out of sight for many people. But even without the cost advantage, natural gas (CNG) and autogas (LPG) offer a benefit: they burn cleaner than gasoline and therefore emit less carbon dioxide. Before deciding on a variant, it is important to inform yourself carefully.

Gas-powered cars are not profitable for everyone. "For those who only drive on freeways with a lead foot, the gas drive is hardly worthwhile. Consumption increases exponentially at high speeds, unlike gasoline cars", says Michael Kruttschnitt from TÜV Süd. Also who drives only few thousand kilometers in the year, is better advised with a conventional gasoline engine.

LPG more expensive than natural gas

Natural gas is a compressed natural gas (CNG), LPG is a liquefied petroleum gas (LPG). Natural gas consists mainly of gaseous methane, while LPG is a mixture of propane and butane that is liquid in the tank. While the tanks in natural gas cars take up a lot of space, the autogas tanks are smaller and lighter. As a result, they often fit into the recess of the spare wheel. Therefore hardly reduce storage space – ideal for retrofitting.

If the vehicle retains its original gasoline tank, it has the advantage of a longer range – even away from a gas station network. However, Michael Kruttschnitt points out: "Driving with gasoline is an uneconomical emergency solution for bivalent vehicles." Driving on natural gas costs only about half as much as on gasoline. Autogas is in turn around 35 percent more expensive than natural gas.

According to ADAC, natural gas vehicles have the advantage that manufacturers offer many standard models. Audi, Fiat, Mercedes, Opel, Seat, Skoda and VW offer various natural gas models ex works. LPG systems, on the other hand, are primarily suitable for retrofitting to gasoline engines. However, there are also a dozen manufacturers who sell a total of 80 model variants ex works as LPG vehicles.

Natural gas suppliers promote the purchase

According to the German Federal Motor Transport Authority (KBA), there are more than half a million gas-powered cars on German roads, of which around 80.000 with natural gas. Last year, more than 6,000 new car buyers bought LPG-powered cars and more than 8,000 buyers bought CNG-powered cars. Used vehicles are correspondingly common on the market.

A subsequent conversion to LPG costs between 1800 and 3500 euros. In the case of natural gas vehicles, the conversion can be quite expensive, depending on the car model. System type costs 3000 to 4800 Euro. In return, many regional natural gas suppliers promote the purchase of a natural gas car.

"We cannot make a recommendation for or against LPG and natural gas, as many parameters have to be taken into account when making a decision", says Andrea Gärtner from ADAC Fahrzeugtechnik. Not all conversions are profitable. ADAC has developed a cost calculator for this on its website, which interested parties can use to compare fuel types. "For a retrofit the vehicle should not be too old and in a good condition, so that the investment still amortizes", says Gärtner. Another aid to decision-making is provided by the website www.Amortization calculator.

"The nearest refueling station in the vicinity is also important. The more often a gas vehicle has to run on gasoline due to a lack of fuel, the less economical it becomes," says Gärtner, says Gärtner. For example, there are currently around 6700 filling stations in Germany with autogas dispensers, but only around 900 with natural gas dispensers.

If you drive a lot abroad, you should bear in mind that adapters are required in some places. Once the special gas is in the tank, gas-powered vehicles are generally no different from gasoline or diesel-powered vehicles when they are being driven.

Main inspection is more expensive

However, the main inspection (HU) will be a bit more expensive. For example, a gas system inspection (GAP) is carried out as part of the main inspection, which costs an extra 20 euros. The auditor can waive this if the last CAP was not more than twelve months ago. A CAP is also due after every repair of the gas system and after an accident in which the gas system was impaired. Older natural gas steel tanks that have been approved in accordance with the Pressure Vessel Ordinance must be inspected by TÜV every five years. If they are housed in the vehicle in a corrosion-protected manner, the period is ten years.

The inspection costs can also be higher than for gasoline or diesel vehicles. The reasons for this are special spark plugs, a valve clearance check and additives that have to be topped up. "In order to have an overview of the height of the possible additional inspection costs, one should let these point out before the autogas conversion or the purchase of an autogas vehicle of the workshop ", says Gärtner.

But regardless of whether a gas-powered car is converted or purchased new. Who decides for it, should not hesitate too long. The reason for this is that the rates for gasoline engines, which are more favorable than those for diesel, still apply for motor vehicle tax. However, for the time being only until 2018.
