[edit] 3.4

The first use was in the 1949 Jaguar XK120, where it was billed as the 3 1/2 liter. This was a 3.4 L (3442cc) version with an 83mm bore and 96mm stroke. It had an iron block and an aluminum cylinder head which delivered 160 bhp at a compression ratio of 8:1, rising to 210 bhp with the C-Type head as raced at Le Mans. A 4-cylinder XK variant was never produced.

This engine was used in the following cars:

[edit] 3.8

The larger 3.8 L version was released in 1958. It was a bored (to 87mm) version and produced up to 245 hp.

This engine was used in the following cars:

[edit] 4.2

The 4.2 liter version was officially released in 1965, though racers had been boring the 3.8 out all the way to 4.2 liters for years. The official bore was 93mm, and the engine produced from 170hp(DIN) in the Series 2 XJ6, to 265hp(Claimed) in the E-Type.

This engine was used in the following cars:

It was also used in the following military vehicles:

The 1987 Jaguar XJ6 was the last Jaguar car fitted with the XK6 engine. In 1992 the last Daimler DS420 Limousine was produced. Like all other DS420 limousines, it was equipped with a 4.2L XK6 engine.

The amount of time the 4.2 XK engine has remained in production means it has the rare accolade of having been in service in cars spanning 6 consecutive decades.

[edit] 2.4

The 2.4 was a de-stroked (to 76.5mm) version of the 3.4, and produced 133 hp. It featured Solex downdraft carburettors in the original Mark I and Mark II saloons.

This engine was used in the following cars:
