The V8 Jaguar engine is an awesome piece of kit and one of the best engines Jaguar have made.
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.
