Even if it was a Ford design made at the Ford plant in Bridgend! It is used in other cars, including the Lincoln LS the 2002-2005 Ford Thunderbird as well as in several Land Rovers and the Aston Martin V8 Vantage.
Bottom line: a cracking engine, especially the supercharged version in my friends S Type R.
The engine was designed by Jaguar not Ford, and a simplified version is used in the Lincoln etc.
The supercharged version is indeed a fabulous engine. I've been fortunate to own an S Type R which of course uses the 4.2 version. That has got to be one of the most underrated cars ever.
The 5.0 litre supercharged engine would have been magnificent in the new Aero.
