Rumors put forward at the end of 2019 are confirmed. BMW will withdraw its 3.0-liter four-turbocharged diesel engine in September.
Known internally as the B57S, the quad-turbo diesel was introduced in 2016 and was an exception in the diesel world. Considered a formidable compromise between performance, comfort of use and consumption, it was first introduced on the 750d xDrive and 750Ld xDrive limousine, then fitted to the BMW M550d sedan and Touring, and recently the BMW X5, X6 and X7 SUVs .
The 3.0-liter quad-turbo inline-six engine produced 400 horsepower with a whopping 760 Nm of torque. The X5 M50d only took 5.2 seconds to sprint from 0 to 100 km / h. The larger X7 M50d does it in 5 ″ 4. Expensive to produce, not profitable enough and too expensive to convert to the new standards, the big 4-turbocharged diesel is not yet available for replacement.
Final edition… Romanian!
The B57S will nevertheless be entitled to a strong start with two special editions of the X5 and X7, rightly named “Final Edition”. However, these special editions will be reserved for Central and Eastern Europe, and mainly Romania, where this engine has been very successful. For this swan song, the models will be over-equipped with "Final Edition" entry thresholds and a fairly long list of features, such as laserlight headlights, semi-autonomous driving, head-up display, Harman Kardon premium audio system, acoustic glass, side windows soundproof glass, a "Crafted Clarity" trim on the interior, etc.
In the meantime, the honor of the famous 3.0-liter 6-in-line diesel is being defended by the new 40d biturbo with its 340 hp and 700 Nm of torque. The latter complies with the Euro 6d standard applicable in 2021 thanks to, among other things, an alternator-starter and a 48V electrical system. It will equip the xDrive40d versions of the X5, X6, X7, 5 and 7 series.
