An evolution of the 1964 DOHC prototype “XJ13” engine, the Jaguar V12 engine is a family of SOHC internal combustion V12 engines with a common block design, that were mass-produced by Jaguar Cars for a quarter of a century, from 1971 to 1997, mostly as 5.3‑litres, but later also as 6‑litres, and 7‑litre versions that were deployed in racing. Except for a few low-volume exotic sports car makers, Jaguar's V12 engine was the world's first V12 engine in mass-production. For 17 years, Jaguar was the only company in the world consistently producing luxury four-door saloons with a V12 engine. The V12 powered all three series of the original Jaguar XJ luxury saloons, as well as its second generation XJ40 and X305 successors.
The Jaguar XJ-S is a luxury grand tourer manufactured and marketed by British car manufacturer Jaguar Cars from 1975 to 1996, in coupé, fixed-profile and full convertible bodystyles. There were three distinct iterations, with a final production total of 115,413 units over 20 years and seven months.
The Jaguar XJ220 is a two-seat sports car produced by British luxury car manufacturer Jaguar from 1992 until 1994, in collaboration with the specialist automotive and race engineering company Tom Walkinshaw Racing.

According to Jaguar, an XJ220 prototype managed a Nürburgring lap time of 7:46.36 in 1991 which was faster than any production car lap time before it.

It was later upgraded to the Porsche LMP1-98 before being retired. Only two cars were ever built.

The Eagle MkIII won 21 out of the 27 races in which it was entered and is considered one of the most successful and technologically advanced designs of the IMSA GTP era — "a car that proved so overwhelmingly dominant that the class for which it was created has now been assigned to history", according to Racer magazine.
The Jaguar XJR-10 is an IMSA GTP sports prototype race car, designed, developed, and built by TWR for Jaguar, with the aim of competing, from 1989, in the IMSA GT Championship. Jaguar XJR-10s competed until 1991, before Jaguar replaced it with the Jaguar XJR-16.

The Jaguar XJR-17 was an IMSA Lights racing car, built by Tom Walkinshaw Racing. Rebuilt from a Jaguar XJR-16 for the IMSA Camel Lights, the XJR-17 never competed in the event due to funding issues and has since only been used in a few minor British events and historic races. It used a modified version of the XJR-16's 3.5-litre V6 engine, stripped of the twin-turbochargers and producing a claimed output of 450 hp, whilst its bodywork was cobbled together using various parts from older Jaguar XJR Sportscars.
