It is onerous to argue with the unique. Later generations had higher efficiency and fancier interiors, however the Jaguar XJ Collection I (1968-1973) set the tone for all of them. Jaguar founder Sir William Lyons used the XJ to exchange Jaguar’s earlier sedan lineup. And whereas it borrowed some styling components from the earlier Mark X and 420, similar to quad headlights, the XJ was a lot sleeker.
The primary XJ was powered by the identical 4.2-liter dual-overhead-cam inline-six used within the E-Kind, making 246 horsepower. Jaguar claimed a sub-nine-second zero to 60 mph time and a high velocity of 124 mph. A 5.3-liter V12 (additionally shared with the E-Kind) was launched, growing the highest velocity to 140 mph and making the XJ the quickest four-seat automobile on the planet on the time.
The X350/X356/X358 (2003-2009) in the meantime was the final word conventional Jaguar XJ, combining the acquainted styling from earlier generations with an aluminum monocoque physique shell. Tesla would later use aluminum to cut back the load of the Mannequin S, however on the time solely Audi was constructing luxurious sedans utilizing the light-weight metallic. Switching to aluminum diminished the load of the physique shell by 40%, based on Jaguar.
Regardless of the same styling, the X350 (and X356 and X358 facelifts) was additionally brawnier than its predecessor. The V8 engine grew to 4.2 liters and 294 hp, whereas the XJR obtained a supercharged model making 390 hp. This was the final XJ developed below Ford’s possession. The Blue Oval bought Jaguar to India’s Tata Motors in 2008.
