How much is the power of the 12 cylinder V-engine: the power of the 12 cylinder v-engine is in a range from 264 bhp to 860 bhp.
Which cars use 12 cylinder V-engine: few automotive manufacturer engineered and built V12 engines.

Each bank of a V12 engine essentially functions as a straight-six engine with perfect primary and secondary engine balance and outstanding smoothness: at any given time, three of the cylinders in a V12 engine are in their power stroke, reducing gaps between power pulses.
Racing use of 12 cylinder V-engine: V12 engines are not the choice in last seasons but were often used in the past in Formula One. The first V12 engine used in Formula One was in the 1964 Honda RA271 and in 1966 season V12 engines was the choice with new V12 engines from Ferrari, Maserati, and Weslake.
