It’s no surprise that with the advances in electrification that automakers are starting to thin out their engine offerings. Just a few years ago, for example, you could buy Mercedes-AMG C63 with a big, beefy V-8 engine. Today, however, the entire C-Class lineup will only be offered with a four-cylinder. Mercedes has a good reason, of course, but it’s a clear sign of how much the industry is changing. So is the introduction of cars like the BMW i4 or the recently leaked BMW i4 M50. Now, we have word that BMW is actually about to kill off some 50-percent of its engines, leaving us with one major question: What BMW engines stay and which ones go?
