Who needs downsizing if he can get out 435 horsepower from a big V8 block with virtually no turbo lag while still using only 7.2 liters of diesel per 100 kilometers still quite can achieve moderate fuel consumption for such a big SUV? While the competition really is only six-cylinder, try the Ingolstadt with a big eight-cylinder for the Audi SQ7 and therefore give an outlook for future, powerful engines from the VW Group.
When the world's strongest diesel SUV, the Audi SQ7, the makers put first on a new unit and so squeeze 435 horsepower from a big V8 block. Named as "EA 898" new engine block with 4.0 liter engine to replace the previous 4.2-liter V8 that makes Cayenne S Diesel propulsion currently still in the Audi A8 or the Porsche. And with the new engine at the same time is an outlook on the drive options in other series of the Volkswagen Group are given because Andreas Fröhlich from Engine Development said: ". We strive for a group-wide use of"
And the developers put then also there the first time in the automotive industry employed, electrically driven compressor, which receives its power from a 48-volt vehicle electrical system part. Thus, the compressor can be ramped up to 70,000 rev / min within only a quarter of a second of 0th The result: "The turbo lag is gone now," as Klaus Bugelnig, Technical Project Manager at Audi reported. This enormous power is then a quite moderate consumption of 7.2 liters of diesel over 100 kilometers.
