Over the many years, BMW engineers in Munich have delivered some impressive engines in their cars as well as SUVs. From the creamy straight six engines to the powerful diesel engines that delivered near M3 petrol powered performance.
However, emissions have become a big issue in Europe and North America and this has resulted in the slow demise of the diesel engine.
Yes, diesel engines are not emission friendly and this is why the BMW management decided recently that their popular B57D30S0 diesel engine will be put into retirement.
To the oil-burning fraternity though, the engine that would be remembered most fondly would perhaps be the soon-to-be-retired B57D30S0.
This engine code may not mean much to the wider car community, but those in the know would tell you that this sequence of letters and numbers refer to BMWs quad-turbocharged straight six diesel engine.
A spin-off from the conventional B57 series of single turbo diesel straight six, BMW strapped on three additional snails in 2017 as a response to the increasing demand for more performance in the Bavarian brand’s increasingly large number of larger-sized SUVs.
BMW is no stranger to strapping ludicrous amounts of turbochargers to its oil-burning engines, as demonstrated by the tri-turbocharged N57 range. However, this quad-turbocharged successor was another giant leap ahead in terms of performance and efficiency.
With the same number of turbochargers as a Bugatti Chiron, this power plant has been known to put out 294 kW and an earth-moving 760 Nm of torque.
Mated to an eight-speed Steptronic transmission, this powertrain combination has been said to easily provide brisk acceleration and ample amounts of overtaking power in even the heaviest of BMW vehicles, such as the gargantuan 2.5 tonne X7 SUV.
This powertrain was not only immensely powerful, but also had commendable efficiency. When installed in the smaller X5, BMW claims that a cruising fuel consumption 14.2 km/l was an achievable goal.
In addition to that, the powertrain combination was also deemed refined enough to make its way into the flagship BMW luxury sedan in the form of the 750d.
Usually denoted with the 50d suffix, this engineering marvel found its way into the X5, X6 and X7 SUVs and also the 5-Series as the M550d and the 7-Series as the 750d.
Alas, this engine will soon be killed off by BMW due to cost and the lack of sales. The calls for electrification and the dirty truth about diesels has also not helped matters.
A limited run of X550d and X750d will be produced to commemorate the end of this fascinating oil-burner. No word on the exact specs yet but these ‘Final Editions’ will only be sold in limited markets around Eastern Europe.
