Learn the story of the Jaguar 6.0-liter V12—one of the Coventry car maker’s more memorable engines—in this original factory video.

There’s a intriguing mix of old-world craftsmanship and cutting-edge technology on display in this fine old factory Jaguar film—from drafting boards to color CAD animations. Developed by Harry Mundy and Walter Hassan and introduced in 1971, the mighty V12 was just the second engine series in the history of the English carmaker, following in the footsteps of the company’s legendary twin-cam inline six. In this clip, the spotlight is on the 6.0-liter version of the SOHC V12, created by stretching the stroke from 70 mm to 78.5 mm. Combined with the original oversquare bore of 90 mm, this boosted the total displacement from 5.3 to a full 6.0 liters, or as we like to say here in the USA, 365.7 cubic inches.

This final HE 6.0L version of the V12, updated with May Fireball high-swirl combustion chambers, electronic fuel injection, Nippondenso distributorless ignition, and other advanced features, was used to fine effect in a number of Jaguar models.  The 1993-97 XJ12, the XJS and XJS-R, and the Jaguar’s sister, the 1993-97 Daimler Double Six, all made use of the big Twelve-shooter. Jaguar mechanics bowed in respectful silence—and often, a touch of intimidation—when they opened the hood and stood face-to-face with all the magnificent hardware. Take in some of the Coventry magic and mystique in the video below.
