What's the difference between a V8 engine and a V12 engine and which is better?

Answer:That means, that a V8 needs larger cylinders with bigger bore and more stroke ... That is the reason that many luxury sedans rely on V12 engines - they run significantly smoother than V8 engines. On the other hand a V8 engine is simpler, lighter and has a better efficiency (less moving parts).

it really depends on what u want if you want more power usually a v12 has more or if you want a lighter engine I would go for a v8
