The luxury crossover isn\u2019t the only BMW of this size to wear a 40d badge. The 4 Series Coupe and Convertible are still available as 440d models in some parts of the world. That said, we\u2019re wondering how long these cars will stick around. Both body styles are expected to remain in production until mid-2029, but it\u2019s unclear whether the diesel M Performance versions will survive until the very end. With emissions regulations getting stricter across Europe, diesel engines remain the most vulnerable.<\/p>\n
Diesel Is Not Dead (Yet)<\/p>\n But that\u2019s not to say the B57 is on its way out. Aside from the X3, pretty much all of the larger BMWs can still be had with a 3.0-liter diesel engine. Munich also sells its compact cars with a four-cylinder diesel, and there hasn\u2019t been any news about the B47 going the way of the dodo anytime soon. Rumors suggest a detuned B57 could replace the B47 in the X3 20d<\/a>, but nothing is official.<\/p>\n While we don\u2019t have a crystal ball, logic suggests diesels will likely disappear first from smaller cars like the 1 Series\/X1 and 2 Series Gran Coupe\/X2. Although BMW isn\u2019t committing to a new diesel 3 Series just yet, we honestly can\u2019t imagine the lineup without at least one version with a \u201cd\u201d in its name. Even with the B57 out of the picture in the 3 Series, the B47 should soldier on for at least one more generation of the sports sedan.<\/p>\n Although diesel isn\u2019t about to disappear overnight, its slow death is becoming increasingly difficult to ignore. Once the default choice for high-mileage drivers and the backbone of the European car market, the diesel engine has steadily lost ground to gasoline, hybrids, and fully electric powertrains. In its heyday during the mid-2010s, diesel had a market share of a little over 50% in Europe.<\/p>\n Why Automakers And Customers Are Falling Out Of Love With Diesels<\/p>\n Stricter emissions regulations, increasingly expensive after-treatment systems, and changing consumer preferences have made diesel-powered cars harder and more expensive for automakers to justify. At the same time, hybrids have emerged as a more eco-friendly choice and increasingly efficient alternative for buyers who still want to avoid going fully electric.<\/p>\n![\"2027](\"https:\/\/www.europesays.com\/germany\/wp-content\/uploads\/2026\/09\/1788866954_570_2027-bmw-m350-review-49-830x553.jpg\" "\\"2027")
