The Jaguar XJ is a series of different Jaguar’s most luxurious sedans. The series was built from 1968 to 2019, and the abbreviation stands for ‘experimental Jaguar’, which explains much of the cars’ uniqueness. Over the decades, the XJ series had a range of different model codes and names, often based on the splendid engine configuration. In addition to offering ‘ordinary luxury’, Jaguar decided to offer ‘supreme luxury’ under its subsidiary brand, Daimler.
Jaguar XJ Mk IV – X351
The Jaguar XJ Mk IV, also known by its internal reference ‘X351’, represented a futurization from its predecessor in series, the more classic and even somewhat antiquated XJ Mk III X350. It was manufactured from 2009 to 2019 and served as Jaguar's swan song to the XJ series, although initially there were plans for an electric XJ to enter the market.
By modern standards, the X351 boasts an array of sophistication. Under the hood of this luxury car, there are various high-performance engines available, catering to different customer preferences. These include a turbocharged V6 engine with a displacement of three litres, a five-litre V8, and the same V8 engine with a supercharger. There's also a very fuel-economical three-litre V6 diesel engine. Each of these engines holds its ground impressively, as Jaguar ensures no disappointment, and all variants are electronically limited to a top speed of 250 kilometres per hour or 155 miles per hour.
As mentioned, the X351 introduced a lot of new features. The car's frame is made of lightweight aluminium, half of which is composed of recycled materials. In terms of luxury, the vehicle features a touchscreen, a built-in GPS, ergonomic leather seats, ample legroom, and steering wheel controls. The X351 is the quintessential long-distance cruiser, seemingly tailor-made for the average dignitary. British politicians like Margaret Thatcher, David Cameron, and Theresa May chose wisely for the X351 to get transported in.
Production of the XJ Mk IV continued until 2019, but the earlier announced electric XJ never came to be built. The X351 embodies the classic Jaguar spirit with the flair of a British icon.
