The two sedans Opel Insignia and Volkswagen Passat compete for the title of most fuel-efficient gasoline engine in the midsize class. We crown the super-economical with the lowest consumption in practice.
The revised Opel Insignia , Opel prices as fuel-efficient gasoline engine of the middle class – 5.7 liters of Super per 100 kilometers to meet him. Reason enough for us to examine what remains of the promising laboratory results into practice. We have faced the Opel Insignia ecoFLEX 1.4 Turbo VW Passat 1.4 TSI BlueMotion Technology, the standard consumption of 5.9 l/100 km little about it.
The two mid-size sedans try with start-stop system to save high-ratio six-speed transmissions, gear shift recommendation and an underbody panel fuel. Motor end both are equipped with 1.4 liter Turbobenzinern, where the VW is on the modern direct injection, while the Opel injects the fuel into the intake manifold. What really brings the effort, we have analyzed on three different trips consumption. First two limousines had to use the standard route of AUTOZEITUNG complete, consisting of a mix of urban, suburban and highway driving, including a full load share. It is approved, the Insignia smooth seven-liter or 0.7 liter less than the VW Passat . A surprising result is that trade not only around 130 kg lighter, they save as required by a regulated alternator. Second round: this time had the two candidates on the minimal consumption of stretch show how sparingly they can deal with the fuel. The route ran almost exclusively through remote country roads, we sailed with a maximum of 90 km / h constant. Here too, the Insignia with the radiator had just 5.2 l/100 km in front, the Passat approved a Kölsch glass more (0.2 liters more).
SURPRISE ON STAGE THREE
The third line should prove both that “running Turbo, Turbo drinking” the old saying has now lost its validity. On a free highway with no speed limit, we tested how much the turbo gasoline consumption under full load. And the result stunned. In order to reduce the exhaust temperature to protect the turbocharger that VW would have thanks to its direct injection and the resulting internal cooling of the combustion chamber richened the gasoline-air mixture actually less – thus increasing the gasoline fraction is less. Nevertheless, we calculated a consumption of 14.7 l/100 km. The Opel Insignia ranged 11.8 liters, so the third round went to the Opel Astra and the savings he may mount to Crown Law.
CONCLUSION
Opel has not taken the mouth too full, the Insignia ecoFLEX 1.4 Turbo turns out in this comparison as a very efficient fuel-saving car. He can distance the VW Passat 1.4 TSI with BlueMotion Technology package on the standard route of AUTOZEITUNG by a whopping 0.7 liters and is located at 7.0 l/100 km on small car level. Who creates it and is extremely economical way that can be achieved with two limousines values just over five liters. At the full load range of the VW increases consumption of 14.7 l/100 km, but at about the dimensions, while the Opel requires one to about three liters less shipping surcharge.
