Is the BMW V8 flat-plane crank? BMW's 4.4-liter V8 doesn't actually have a flat-plane crankshaft, but as we explained back in 2014, it does have a crossover exhaust manifold that sends an evenly. « Previous Thread Next Thread Building your own flat-plane "P65" engine. A V8 flat plane crankshaft is special and the concept changes the way one must think about engine performance.
Traditional V8 cross planes can build large torque quickly due to the load distribution in two planes at the rod journals. Flat-plane crankshafts are generally associated with European sports cars such as Ferrari and Lotus V8 engines, and cross-plane cranks with American manufacturers. There are some exceptions such as the Ferrari-designed crossplane crank V8 of the Lancia Thema 8.32 and the flat-plane crank 2014-2023 Ford Mustang GT350.

Despite your personal preference, I think we can all agree that these two engines are some of the. This is why flat-plane designs can only be used with small light V8 engines found in some sportscars with smaller displacements, shorter strokes, and lighter piston heads and rods (such as F1 racing cars, Ferrari V8s, and the Lotus Esprit V8). The difference is the flat-plane crank fires each bank at equal intervals, for better intake breathing and exhaust scavenging, at some sacrifice in smoothness.

An inline-6 already has evenly spaced firing pulses and minimal excess weight anyway, so it has many of the same benefits as a flat-plane crank in a V8 -- plus perfect natural balance (i.e. minimal vibration).
