ENGINE BALANCE: Inline 6 vs. V6 vs. VR6 vs. Flat / Boxer 6

Step by step explanation of primary and secondary engine balance: Today we’re hitting on all sixes as we explore the engine balance as well as the strengths and weaknesses of the four most popular six cylinder engine configurations, the inline six, the v6, the vr6 and the flat six. Let’s start with the inline six cylinder engine. We already covered it twice in our videos and many of you by now know that the inline six is a beautifully simple and beautifully balanced engine configuration. It’s beautifully simple because it needs only 1 cylinder head and only 1 or two cams. It also needs only 1 exhaust manifold. It’s only real downside is that it’s long so fitting it transversely is extremely difficult and it needs a relatively long engine bay to fit in longitudinally. But other than the length it’s very hard to fault the inline six. When it comes engine balance the inline six is essentially two inline three engine’s mirroring e
