Fuel consumption: The socket car cheats the hardest-hardest

Refill fuel – depending on the type of drive, the real fuel thirst of cars deviates sometimes more, sometimes less from the standard values ​​in the brochure

Anyone who buys a hybrid car hopes for low consumption. The biggest gap between the theoretical and practical thirst for fuel is here. Another alternative drive is best.

ZIt is well known that theory and practice are worlds apart. Another well-known example is the consumption figures in new car brochures, which often have little to do with the real thirst of the cars on the road. But there is news to report: hybrid cars cheat the most in this regard, and some petrol engines are better than those in the catalog. That was the result of a test by the ADAC.

But let’s start with the honest types of drive: Natural gas cars have the smallest difference between paper and everyday value. As the ADAC found out in its everyday check with a total of 345 vehicle models, the CNG-burning cars only consume an average of nine percent more than promised.

The front runner among the natural gas vehicles is the VW Caddy Ecofuel, which even undercut the prospectus value by four percent. On the other hand, the Fiat Panda Twinair CNG needed 27 percent more than stated. The testers attribute the overall good result to improvements in the conversion from petrol to gas operation as well as the use of particularly heat-resistant materials. These ensure good drinking habits even with high load requirements.

The conventional gasoline-powered vehicles performed hardly worse than the natural gas-powered vehicles, with an average deviation of up to ten percent. Above all, the technical improvements of the past few years are finally having an impact, according to the ADAC.

Larger engines for a change a role model

Larger engines are largely responsible for the good cut. In practice, the Chevrolet Camaro Convertible with V8 engine requires 17 percent less fuel than indicated. The sports cars Audi R8 Spyder V10 and Nissan 370Z (with V6 engine) are also more economical than on the sheet..

The small cars are different: for example the two-cylinder small car Fiat Punto Twinair is responsible for an additional consumption of 34 percent according to ADAC. In general, small gasoline vehicles are often much more thirsty in everyday life than the manufacturer’s information suggests. The experts at the car club give one reason for this: Small cars would be driven under full load more often due to their low performance. That drives the thirst.

Vehicles with the third drive concept based on gasoline engines are on a similar level to petrol and natural gas cars: the LPG cars. On average they needed eleven percent more than promised, the extreme poles are the Opel Astra 1.4 LPG with a difference of only one percent and the Kia Picanto LPG with a deviation of plus 28 percent. In general, however, the testers welcome the successful adjustments made by the gas system converters to the alternative fuel.

Large deviations in the diesel

When it comes to comparing theory and practice, the diesel comes off worst of all non-electrified drive concepts. The testers measured an average deviation of 14 percent from the norm. The inglorious front runner is the Jeep Cherokee V6 Diesel with an additional consumption of a whopping 55 percent.

The Skoda Yeti 2.0 TDI 4×4, which even needs one percent less than stated, shows that there is another way. The fact that the diesel, which is actually advertised as a fuel-efficient engine, consumes so much more is mainly due to its relatively high thirst at high load requirements, for example on the motorway. This is not reflected in the official New European Driving Cycle (NEDC), it only takes into account speeds of up to 120 km / h.

In the case of hybrid cars, too, the large difference in consumption is due to the special features of the laboratory test. The testers attested an impressive 25 percent plus compared to the catalog values. Above all, the plug-in models, with their standard consumption levels close to the one-liter mark, ruin the balance sheet.

Hybrid cars don’t have to be sham

You can drive up on the roller dynamometer with a fully charged battery without the amount of energy stored there flowing into the measurement result. In addition, if the battery is empty after around 50 kilometers, the drive switches to conventional hybrid mode.

The disappointment is correspondingly great in everyday operation, where the mini standard values ​​from advertising are no longer even remotely achieved. The diesel plug-in hybrid model of the Volvo V60 showed an upward swing of 84 percent.

The Kia Optima Hybrid Automatic, a car without a socket outlet, shows that even hybrid cars don’t have to be sham packs. He only swallowed 0.4 percent more fuel than advertised. However, like every conventional hybrid car, it also has a much smaller battery than the plug-in versions. The effect for the statistics: even on the test bench, it has to burn far more fuel than variants with a socket.
