先更正英文 inline， 一般开头用I6，不是L6
从书到抄的，绝对不完全翻译，希望可以减少争论。
inline 6 cylinder engines, flat 6 cylinder engines（水平对置） and V-6 engines.
3种6缸机
If you built all three of these six cylinder engines to the exact same specifications -- same displacement, same valves, same intake and exhaust systems, etc. -- they would likely perform nearly identically. Displacement is displacement.
如果前提条件相同，3种没有什么大不了的，争论无必要。
However, there would be a number of differences between the engines in use. Here are several of them to give you a taste:
实际使用，3种有区别。
An inline engine is long and narrow. In small cars in particular, a long, narrow engine mounted transversely can allow a very short hood. In an air-cooled engine, the inline configuration is sometimes harder to cool.
直列，长而窄。
A flat engine is wide and flat. This gives it a low center of gravity.
水平对置，重心低
A V engine is a compromise between the two. It tends to be more cubical in shape.
V型，刚好两种之间，但V型比较大件。
The inline shape needs only half as many camshafts as a V configuration (if using overhead cams), which can lighten things slightly.
直列稍微轻，比V型少一半凸轮轴。
There can be differences in the amount of metal required in the block, meaning that one type might be lighter than the other.
金属的用量有些差别，重量当然就有不同。
There can also be cost differences during manufacture.
厂家的设计最大考虑是成本。
Designers choose among a number of variables when deciding which configuration to use in a car. Variables include cost, space available under the hood, position requirements, existing manufacturing facilities, power to weight ratio, etc.
成本，发动机舱大小，位置，原有生产设施。动力，重量比
People sometimes get religious about engine configuration.
盲目崇拜很无聊。 |

楼主
一个告诉你奥迪2.4发动机会比2.0T发动机好的人，好打极都有限啦，V6造价贵就等于一定比L4好吗？
希望帖子以后保留在技术讨论方面～
