The German portal Bimmer Today reported sad news. In 2020, the story of a titanic turbodiesel with an in-plant designation B57 may end.
B57 is the apotheosis of diesel rage. Six cylinders in a row, 3.0 liter capacity and four turbochargers. The predecessor of the Bavarian genius masterpiece had three “snails”, but the B57 took a step further and received another compressor, ready to pump excess pressure into the inlet at the driver’s first request. The turbine operation pattern is consistent, with one of the high pressure superchargers coming into operation after 2500 rpm and with intensive acceleration.
The return of the “fifty-seventh” is only slightly higher than that of the aforementioned N57 engine with three turbochargers – go beyond 400 hp. and 760 Nm did not allow the possibility of an eight-speed hydromechanical “automatic machine”. However, is it worth worrying when 450 Nm is already available from 1000 rpm?
According to insider information, in the summer of 2020, the company will dismiss the unit, which is placed on the 750d xDrive, M550d xDrive and X5 M50d xDrive, X6 M50d xDrive, X7 M50d crossovers. Why? The answer is simple – a noose of environmental standards draws on their intake tract. The new standards, which will come into force in 2020, mean reducing the average CO2 emissions of the model line to 95 grams per kilometer. This is not easy to do with the B57, because, for example, the M550d xDrive sedan spits out 154 grams, and the station wagon 163 grams.
BMW is far from the only company preparing to put an end to the history of an interesting engine. A similar fate awaits the 4.0-liter V8 TDI from Volkswagen. Volvo abandoned the development of heavy fuel oil units and even Mitsubishi, which has a palette of professional SUVs, announced the abandonment of diesel engines on the main models.
