Environmental badge does not stop Stinker

Are the current test methods of emissions inspection still time? Especially with diesel experts doubt the validity of the measurement method. The requirements for the diesel study are from the 80s.

The establishment of environmental zones has kicked up some dust. They are supposed to reduce pollution of the inner cities by dangerous particles. Therefore, older diesel vehicles that emit very much soot, were banned from smoking.

Into it since they can only if they are retrofitted with a particulate filter and provided as evidence of the cleaned exhaust gases with an environmental badge. New diesel models have the filter as standard now on board. What is the technological effort, however, brings to the residents, no one can say. For whether the required emission levels are met, not controlled.

The legislature is currently writing, for routine emission test (AU) for diesel vehicles, only one function test and an inspection before the so-called opacity of exhaust gases, said Bert corporal by TUV Nord. The examiner looks in determining whether the exhaust system is technically in order. For cars with on-board diagnostic (OBD) is also controls whether the electronic displays an error.

The measurement of smoke opacity of the exhaust is loud corporal with the so-called Opacimeter: This is the revving of the engine blown gas flow through a meter. This one light beam is sent through a tube filled with the exhaust gas and measuring the light fraction that is swallowed by the waste gases ". The absorption must not exceed specified limits.

A more detailed analysis of the emission behavior is by this method, which was introduced in the 80 years to get the biggest stinker diesel from the road, not possible. It can not determine the amount of corporal, according to the emitted soot particles. However, this is crucial, among other things, whether the car gets an environmental badge - and if so, which.

The experts therefore had to consider within the AU is no possibility that a diesel vehicle bears the red, yellow or green sticker on environmental law, recognizes a corporal. Also says nothing about the measurement of whether a retrofit soot filters to function properly and the car still allowed to drive in the LEZ. "The AU we would not notice."

The testing organizations can not be blamed. You must abide by the legally established procedures. "Not" The measurement methods conform to the current state of technology, said Hans-Juergen Maeurer, head of development for testing the expert organization Dekra. The AU-measurement lags behind kind of engine development.

From the consumer perspective is not the current situation unacceptable, says Gerd Lottsiepen of Transport Club Germany (VCD), "Today, customers pay for something that does not work. It would have to come urgently a new trial. "Acknowledges that not a meaningful emissions inspection for customers will be more expensive. It must however be at least ensures that key technical systems work well in the car.

"If you make an environmental test, the test also measure it, is to measure what he" says Lottsiepen. After all, he has not given up hope that the legislature in the future but still grinds to a better measurement methods. Thus, there exists at least a first reflection, the framework of the AU to adapt accordingly.

For the exhaust emission test (AU) for passenger cars are basically the same terms as for the main study (HU). For new cars, according to the ADAC, the first test date after 36 months is due. All the following tests are then at the 24-month rhythm. Freed from the AU principle gasoline remain first registered before 1 July 1969 and diesel first registered before 1 January 1977. Even vehicles with red plates or temporary plates and of agricultural and forestry tractors, self-propelled machinery and trucks are excluded from the investigation.

The Porsche in the ear doctor

The Porsche in the ear doctor

In the automobile will actually leave nothing to chance. True to the motto: "Who wants to feel, must be able to hear," drive the manufacturer great expense to the sound of their vehicles right to vote. Then come even speakers in the exhaust is used.

"The sound of a car is part of the charm of driving," says Rainer Schmidetzki. This has the developers at Volkswagen in Wolfsburg, no doubt. For vehicles for a broad customer base, although one eighth of a possible subtle and balanced engine sound. Not for nothing is about the new Golf the quietest Golf of all time. "But the sport, a model is positioned to sound more meaty and powerful must be the engine."

"The sound there is not an engine," says Bernhard Pfafflin from the Porsche Development Centre in Weissach near Stuttgart. "What we hear from the drive is always a combination of the intake noise, mechanics in the motor and the mouth of the exhaust sound." And the art is to compose these three votes a good sound.

"We have set screws while many", says VW developers Schmidetzki and exhaust system, the engine and the switching logic counts on the transmission. There are also numerous active systems to the speaker in the exhaust system, with which the developer can vary the pitch of a car.

"But the margin is narrow, because the legislature makes us harsh." While only the volume and the tone was not prescribed, but the quieter one car is, the harder you can hear nuances. For high-volume models, the developers strive to beat these limits to partially clear: For quiet sounds noble and puts even a small car in the direction of subjective upper class. "But with cars like a GTI, or even an R-model, we irritate the limits full» says Schmidetzki.

can make only the volume but not of it, however, restricts Pfafflin: "According to everyone, nice contrast, not all sounds." Setting the tone were ignited in the first place, the engine and exhaust system itself: After how many injections as a diesel, how much fuel / air mixture is blown into the combustion chambers of a V6 and the pistons have to travel that way - all that determines the timbre as well as length and diameter of the exhaust system and their pots. The so often quoted tailpipe but has nothing to do Schmidetzki says: "There can let off steam only designers."

In addition to these so-called passive variables, there are a range of active measures for sound tuning, ranging from valves in the air flow to pneumatic valves in the exhaust system, as they are about in the silencers of the Maserati Gran Turismo S used.

What influence can have the electronics, shown by the example of the Mercedes SLK, which has received a facelift in 2008 with the so-called sports engine. The six-cylinder sporty looks but not only because of the higher performance, but also by "a deliberately powerful sports engine acoustics" with strikingly emotional sound design decelerates, says Mercedes. In plain language: The six sounds tough and a little louder than before. And on top of the engine blows when switching back additional fuel into the cylinder, because this blipping sounds a little race track.

Sounds like a car from the outside, but only one side of the coin, restricts VW Schmidetzki developer: "Just as important is the sound in the interior." Where the legislature does not prescribe them, the engineers have a larger playing field - and benefit from them. It is conceivable, for example, the so-called fire wall, so the dividing wall between the engine and interior, electronic stimulating as the membrane of a loudspeaker. "In principle, one could also even" import songs, says Schmidetzki. But instead Madonna roars on this channel, only the engine.

Even with the attention of the Porsche sound developers is at least partially on the interior. must feel, "The driver not only acceleration, but can also hear, that he experienced as pleasure," says developer Pfafflin. No wonder the intake system of the Boxster directly behind the driver's door or the air filter of the Carrera was open to the interior out. "The driver has the engine literally better in the ear."

The fact that the sound designer for the car manufacturers with the advent of electric cars could be inactive, is hardly to be feared. Although electric motors run really silent, and for many customers makes that what the appeal of these cars. But his job at Porsche developers Pfafflin therefore afraid not, "These are new challenges and technologies on which we make our already mind. One thing is certain: even an electric Porsche we would give his own unique sound. "

The fighter jet of the little man

The fighter jet of the little man

Since 1973, there is him. And so far, the Lancer was a very brave and boring sedan with a notchback. But now, the Mitsubishi is combative: The new Lancer is served as "Jetfighter".

For example, while the martial Audi front grill of his current car fleet rather innocuous "single-frame has dubbed" the Japanese say the Mitsubishi Lancer from a "Jetfighter" front-view review.

The fighters from Nippon to make, especially in the lower middle class booty. When will "wolf in wolf's clothing, Mitsubishi's European chief Daniel Nacar said at the presentation, it is expected that a" capture rate "of 50 percent - every second Lancer buyers so you get hold of the competition.

According to Mitsubishi's dynamic martial and designers from the hotel's European Design Centre near Frankfurt in Trebur the new generation of models have marked the five-seat "sports sedan".

One of the most distinctive features include the Japanese, because even "the Jetfighter-front" with obliquely tapered nose sharks and large, trapezoidal grille. There are also muscular flanks and pinched-looking front headlights.

Incorrigible whiners will form in the folding of the bonnet hints at the formal language of Volvo. And feel through the narrow, horizontal taillights reminiscent of the Alfa 159th At Mitsubishi we speak rather of the "wedge-shaped waistline," "short body overhangs" and "a powerful short tail." Unity should prevail in all, at least in the conclusion that the new Mitsubishi Lancer is the sportiest and most striking of the produced series for 35 years.

And the most comfortable. With a length of 4.57 meters, it is almost up to the scale of resources such as the Toyota Avensis graders. The 2.64-meter wheelbase not only provide short overhangs of the body but also for a decent space inside.

Even the back is still enough room for adult Central Europeans - even with front seats pushed back. The offer, moreover, a decent side support. Only the 400-liter trunk is for the vehicle category was somewhat more concise.

The interior itself appears quite high quality - but seems a bit cautious because of the instrumentation a little bad modest. One can also see the positive: The Lancer is easy to use and intuitive. The necessary switches and displays are all available - and where they belong. A functional cockpit without unnecessary frills.

And as usual for Mitsubishi, well processed. A few more trays you would probably want more. And just as easily as the rest-to-use navigation system. Just the search for the demolition button for guidance is the lively guessing game.

Initially, the new Lancer is available in Germany with two units to choose from: a 1.8-liter gasoline engine and a 2.0-liter diesel. Is from the VW and despite the harsh, especially in cold run something and dusty total pump-injector technology but certainly the better choice. He will, of which one is convinced at Mitsubishi in Europe of the volume engine until it is expected to be replaced in 2009 own a Mitsubishi diesel with common rail technology.

With its 140 bhp, the ignition is not a race engine drives, the 1.5-ton Lancer but moving quite fast - even at low engine speeds. It also has the beefy torque of 310 Newton meters of its share, which lies at 1750 revolutions per minute.

The sprint from standstill to 100 km creates the diesel Lancer in 9.6 seconds - only a split more than a comparable BMW 318d strong and heavy. The top speed is achieved at 207 mph.

The consumption is officially at 6.1 liters per 100 km. This is not just a little comparison in the class - the corresponding motorized VW Golf TDI is officially at 5.4 liters of diesel, the 318d even with 4.7 liters. A particulate filter is standard equipment.

Specific value have put the Japanese on the European coordination of the suspension - and with success. It's comfortable enough cushion on one side to make the Lancer a long-distance touring car. But ever so tightly that the sporty driving potential fulfilled the promises of external appearance.

He is consistently good-natured even when it comes to something snappier curves - only with a lot of tuition forces to the rear of a light fawn and the tires to an indignant squeak. To great exuberance sets the electronic down early. The precise steering also helps with there. The six-speed manual transmission is well matched to the engine and can be accurately, quickly and switch to a sedan quite crisp.

The diesel (140 hp) at a price of € 21 490 up available, the gasoline engine with 143 horsepower from 19 250 €. That is quite cheap - especially since even in the basic facilities, "Invite" neatly with what has been hineingepackt.

The competitors are usually more expensive way. The VW Jetta costs about the same practical diesel at least € 25 550, and even the Golf 2.0 TDI is still a few hundred euros more expensive. Already in the pipeline is a sedan version of the Lancer, which will follow in the autumn of next year.

The Lexus IS-F will in the traditional area of AMG and BMW M3 poaching. dell battery In two parts, we say if he can offer the Teutonic competition forehead. Read today really as emotionally and especially how the Asian sports racer is.

The harshest of the Lexus sports car roars when it is slow: each downshift via steering wheel paddles are in a lower gear, the engine with a powerful blow blipping. Eight levels, the circuit - plenty of room for much blipping.

But it is not the rich sound alone, the Lexus fast sprint in one class with AMG-Mercedes and BMW M-leaves. The performance fit into this society and the still relatively understated outfit. And the price even more so.

Who here have so far wanted to be on the road in a thoroughbred sports car that inspiron 1545 battery still have the space of a normal sedan and the one's brute power should not see at first glance, the usually employed at the Mercedes AMG BMW shop or wherever the M stood on it.

Now there is from Lexus, Toyota's premium brand, is another alternative: the IS-F competes against M3 and C 63 AMG. The car share solll Toyota's own admission, the notchback cars in this class standards.

Quite want that the IS-F, because the competition is to be but too well. Let's start with the performance. PS 423 brings the V8 from its 4660 cubic capacity. Certainly not bad - but not necessarily the measure of things. The BMW M3 is just three including HP, which offers 63 C 34 horses more. The power delivery is as close together like.

4.8 seconds is to Lexus for the sprint from a standstill to 100 km / h. That is the level of a Porsche 911 Carrera S and who losprescht on the open road with him, has no doubts about the veracity of this promise.

But the M3 only one - not noticeable in everyday life - takes longer and 100ths of seconds, the AMG is brisk with 4.5 seconds on it. Deadline is the German racers in electronically limited 250 km / h. The Japanese paid a premium rate to 270, before the inspiron 1525 battery electronics intervene.

The details to enter in optimized aluminum engine that is based on the engine, the LS 600h, creates a maximum torque of 505 Newton meters. With an average consumption of 11.4 Super IS-F is expected, not just a cheaper version. But who is out to find it is already closer to the hybrid models from Lexus.

In addition, the AMG are at 13.4 liters Super Plus and the M3 with 12.4 liters of the Lexus values. In reality, all three values are only theoretical anyway - who is traveling with one of the longer route to three, the motor will spin richly anyway faster than the computer on the standard chassis dynamometer.

Outdoor exercise, the Lexus IS-F in similarly subtle hint of his potential as his two rivals. A little spoiler cosmetics, the four tailpipes at the rear, forged in the grille drawn lamps, developed together with BBS, 19-inch alloy wheels - you have to look really close to notice who you have going on.

More than meets the eye is the motto of this vehicle class - even inside. Tasteful leather, fine workmanship, sportsmanship suggestive materials. The seats are comfortable and anatomically and provide for fatigue during long trips to arrive. In fast corners but they could offer a little more lateral support.

Rear is not quite so lush. The knee-is just as intoxicating as the low for the head - but that's no different with the competitors. In contrast, however, is the transmission, which provides in the IS-F for a comfortable blend of luxury and sporty driving. The eight-inspiron 15 battery Direktschaltautomatik just fits perfectly. If you have to work itself, which can unscrew in manual mode with steering wheel controls the corridors min each up to 6800 rpm.

Each gear change is implemented without noticeable delay immediately. The automatic mode, however, is faster than any manual work. In addition, the automatic interpretation of different speed levels vary. The eighth gear is about to optimize fuel consumption for longer kept, the first gear, however, is very short to make for a powerful start from the state.

Driving can be the Lexus IS-F fast and very, very athletic. However, he comes to the agility of a M3 not approach - ensuring even the higher weight and the sportier suspension of the BMW. The steering of the Lexus might be a bit more direct and precise view of the performance.

And the electronics sometimes even a slight problem with the traction at the rear. AMG and the M3 especially when driving then give it a sporty feel safer.

Fairly confident are Lexus is in pricing - again, at least at first glance. The Japanese will cost € 69 600 for its luxury sports - almost 5000 € more than an M3 and even more than 1770 € a C 63 AMG.

At least around this price perspective but then when you look at the additional cost makes lists lenovo thinkpad t61 battery: The Lexus comes equipped largely complete - the other other hand, we may cheerfully order in addition to come to a similar equipment level to pay - and.
