It’s not unusual to find an engine that was built by chopping cylinders off of a bigger engine. Jaguar’s supercharged V6 used to power the F-Type was created by blanking out a couple cylinders from a V8, and shrinking the remaining cylinder bores a little. The Gen-V 4.3-liter Chevy V6 found in the 2014 Chevy Silverado is another example, being an aluminum-block six-cylinder built by slicing a couple cylinders off of a V8. Turning a V12 into a V8, though, seems to be one of the least common ways to build a new engine out of an old one, and we can see why: You’ve already got a splendid V12, so why cut it off at the knees?
