I know this might sound like a stupid question, but I don't know anything about cars. I was looking on wikipedia about the new Jaguar XJ models (X351), and it says there are three different types of engines: the 3.0 litre V6 Diesel, 5.0 litre V8 Petrol, and the 5.0 litre V8 Petrol supercharged. I don't understand the difference between these engines. Can someone explain it to me? Thanks.|||The litre size is the engine displacement (the amount of air and fuel that can fit in the cylinders). The "V" denotes the type of engine - specifically the way that the cylinders are oriented in the engine block. The number after the "V" is the number of cylinders. The petrol/diesel is obviously the type of fuel that is used. A supercharged engine has a compressor (or supercharger) that compresses the air/fuel mix before it goes into the cylinders effectively making that cylinder able to burn more air/fuel than it could without the supercharger.
Knowing nothing about cars....most of that is irrelevant to you. Focus on the power and fuel consumption for the different engines and whether you want petrol or diesel. You may also want to test drive the different configurations as they will have different driving characteristics.|||The diesel offers a reasonable amount of power and both good economy and great longevity too.The V8 petrol is the base engine and would satisfy most people. The supercharged engine offers the most power when you need it and reasonable fuel consumption if you do not press too hard on the gas pedal too often.
