If a 560 PS hybrid Porsche is specified with an average consumption of 2,2 liters per 100 kilometers, the physical question arises as to whether that is even possible. Answer: theoretically yes, unlikely in everyday reality. The official value is in part actually window dressing that has been devised at many green tables in Brussels and approved by our government. It was to be expected that the car opponents from the “Environmental Aid” association would make these surreal consumption figures a topic.
The fact that the association is now criticizing the auto industry is, however, completely wrongly addressed. That is simply easier than questioning the EU Commission's “New Green Deal”, which the Greens supported so enthusiastically, at this point. It's actually shocking which kindergarten games are played in both Brussels and Berlin. The "give-you-me-give-you-I-you-game" in the negotiation procedure leads to abstruse excesses, which are then regularly hailed as a "breakthrough" after the nightly meeting.
Is the test procedure a scandal?
The "environmental aid" association has tested four plug-in hybrids (Mercedes A250e, Porsche Cayenne E-Hybrid, Volvo XC40 T5, Volvo XC90T8) in a "practical test" and allegedly found that the standard values were exceeded by more than 600 percent. This realization culminates with the "environmental helpers" to the "extent of a new scandal in the automotive industry". The club has a particular brand in its sights: “At 499 g CO2 / km, for example, the monster SUV Porsche Cayenne Plug-In Hybrid, which is supposedly particularly environmentally friendly, emits more than five times the EU fleet limit in Sport Plus driving mode . "
The "scandal" will be staged right on time for next week's auto summit initiated by the auto federal states at the Chancellor's premises, who incidentally has long since withdrawn her favor from the auto industry and appears to be ready to use the EU's Green Deal for further instruments of torture to allow. “It makes me angry,” a division manager of a large car manufacturer tells me, “how superficially our government is acting and helping to destroy an important pillar of our economy. I don't have the impression that Ms. Merkel thought the strangulation of our industry from the end, as she always claims. "
Full throttle without an electric drive naturally increases consumption
Back to the plug-in hybrids: The car opponents are right that the low consumption figures for plug-in hybrids are determined by an "absurd laboratory test procedure". And these values are suitable for suggesting extremely low fuel consumption to car buyers. However, the test procedure used by the “environmental workers” is no less absurd. To put it simply: While the test procedure assumes that the plug-in's battery is fully charged when it starts and that up to 70 kilometers can be driven electrically, the "environmental workers" started with an empty battery and immediately gave full throttle to the combustion engine. It is actually logical that under these circumstances normal premium gasoline is burned instead of electrical energy.
The subject is complex and the truth is not easy to discern. "I drive my plug-in to and from the office every day, hang it on the charger in the evening and almost never have to fill up," reports a convinced plug-in. He reassured him that he could still drive long distances if necessary, then with gasoline. “But in everyday life I drive purely electrically.” What is the “real value” demanded by the environmental aid association that should be shown? Is it the plug-in commuter or the long-distance driver?
The auto industry did not do the testing procedure
If the "environmental workers" triumph now and pretend that they have caught the auto industry cheating, that is not only dishonest, but crude populism. The Association of the Auto Industry (VDA) has rightly rejected the allegations. “Here the obvious attempt is being made to defame a modern type of drive. Plug-in hybrids are proven to be on the road with zero emissions on distances of up to 70 kilometers, provided the e-batteries are charged. If, however, a plug-in hybrid is driven with an empty battery and in extreme sport mode, the consumption figures are higher - as with conventional combustion engines. ”However, the“ environmental workers ”do not want to follow this physical reality.
In addition, the car manufacturers did not do the test, but EU bureaucrats. These specifications have led to the fuel consumption data for a Porsche Panamera with 560 system horsepower showing 2,2 liters of gasoline consumption, but the consumption of 18,1 kW / h of electricity per 100 km, which is also mentioned, is often overlooked. If you drive off with an empty battery and only use the 440 hp petrol engine, you shouldn't be surprised if your petrol consumption is well over 2,2 liters.
The consumption measurements cannot be perfectly standardized
The discussion about plug-in hybrids now makes it clear that the entire EU consumption regulation cannot do without mathematical somersaults, if not to say sleight of hand. Because plug-in hybrids are undoubtedly the right step towards e-mobility, but the consumption specifications (cannot) respond correctly to the reality of all drivers, purely theoretical approaches remain. No consumption standard will ever be able to map the actual consumption of individual driver personalities. While the plug-in commuter proves that he can even stay below the consumption figures if he always drives off with a fully charged battery and only covers distances of up to 70 kilometers, the hurried long-distance driver will also find completely different consumption levels in the plug-in.
"Environmental Aid" Federal Managing Director Jürgen Resch says: "We are calling for this absurd promotion of climate-damaging plug-in hybrids to be stopped." However, it is not to be expected that the Chancellor will be able to respond. In addition, autopilot driving will be on the agenda for the next auto summit on September 8th. In order to get actual consumption values, an electronic consumption control proposed by EU politicians would have to be installed in every vehicle, which, like the mileage, stores the absolute consumption for years. This - so it is intended - could be read out at the next TÜV appointment. This is the only way to determine exactly how much each vehicle actually consumes or how much CO2 it has produced.
