That looks like a 4.2 Supercharged Jag engine. Made by Ford. |

MPG is an extremely subjective and often contentious topic. Some folks claim to get x, whereas other claim to get x/2.

Wow. I didn't know that. I'm guessing that 4.4 is the old BMW unit. But looking at the picture I don't think it is??? |

The older models (like early 2000's) I believe were BMW....but 2008 is I believe the jag engine. Ford would be my second guess. 2014 FF Autobiography 5.0 SC

Well being that my M5 gets 10 MPG I'll take 14 lol. But on the highway its only rated 18MPG...I can get a little more then that on the highway. Most of my commute to work is stopping and going. If I want better MPG I'll hop on the Triumph Speedie....gets around 35-40 2014 FF Autobiography 5.0 SC

According to Wikipedia they did, perhaps it was for US Markets only? Micro cat certainly lists a "4.4 AJ Petrol" engine.
The AJ-V8 was also made in a 4.6 litre capacity for Aston Martin apparently. |

This might have something to do with it.
From wikipedia so may not be accurate, but it looks like the standards for octane rating differ in the US from British Standard. Octane is only half the story, the calorific values may be lower too, which means the engine needs more of it to generate the same power. |

It's made in a Ford factory (Bridgend in Wales i think), though it was designed by Jaguar for Jaguars. The only Ford it was used in was the Thunderbird, it's basically a factory within a factory. Saying it's made by Ford is a bit simplistic. On the same basis the Aston Martin V12 engine is made by Ford in Cologne, though again it's built in a separate compound within the Ford factory. |

Stan, I have one too. NAS spec included the 4.4 AJV8 (non Supercharged) from 2006-2009. Only petrol engined FFRR that's not "Premium fuel required."  They're all badged HSE here, but the spec varies between an UK Vogue and Vogue SE. Actually, rather more common than the premium SC models.
