1968-1973 JAGUAR XJ6 SI 4.2 specificationshttp://www.classicandperformancecar.comClassic and Performance CarClassic and Performance Car
The optimum Jaguar XJ came with the XK engine in 4.2-litre form, and once again proved that Browns Lane was capable of producing the best affordable saloon in the world. Unlike the 2.8-litre version, of which few survive, the 4.2-litre XJ in Series I form was popular with buyers and has a good survival rate today. It’s easy to see why, as the ride quality and interior comfort are astounding, and the roadholding is tenacious. Rust is a significant issue, though, and few unrestored cars remain. The best examples are now appreciating rapidly.
