A V10 engine is a V engine with 10 cylinders in two banks of five, which produces a distinct exhaust note.[citation needed]
The V10 is essentially the result of mating two even-firing straight-5 engines together. The straight-5 engine shows first and second order rocking motion. Here it should be assumed that the crankshaft with low second-order vibration is used and the first order is balanced by a balance shaft. By mating the straight-5 banks at 90 degrees and using five throws the balance shafts balance each other and become null. The firing sequence is odd (BMW M5, Dodge Viper). Using an 18° split journal crankshaft the firing order can be made even, and the two balanced shaft do not balance each other completely, but are combined into a single very small balance shaft (Lamborghini Gallardo, Ford 6.8 V10). Using a five-throw crankshaft and 72° bank angle the firing order can be made even, and the two balanced shafts do not balance each other completely, but are combined into a single small balance shaft (Lexus LF-A). A 36° degree bank angle and a 108° flying arm crankshaft would allow even firing without a balance shaft and smaller counterweights, but would be impractical.
