The Jaguar XJ (X351) is a saloon car built by British manufacturer Jaguar Cars, later known as Jaguar Land Rover, from 2010 to 2019. It is the fourth-generation of the Jaguar XJ model. Referred to internally within Jaguar as the X351, it was announced in 2009 before going on sale in 2010, and combines revised styling with underpinnings of the previous Jaguar X350 generation.[4] [5] The model was discontinued in 2019. It is the final generation of the XJ, after the electric Jaguar XJ was cancelled in February 2021.[6]

Overview

Jaguar invited Jay Leno to unveil the new XJ during the launch at the Saatchi Gallery in London on 9 July 2009.[7] The event was broadcast live on the Jaguar website. The US model was unveiled at the 2009 Pebble Beach Concours d'Elegance.[8]

Production of the car was due to begin in September 2009, with first deliveries being made in early 2010.[9] Production later began in 2010, with the car arriving in dealer showrooms in May 2010.[10] [11] Production was initially carried out only at the Castle Bromwich Assembly plant in Birmingham, England.[12] From 2014, assembly from complete knockdown kits, or CKD, of the XJ commenced at Jaguar Land Rover's facility in Pune, India.[13]

Design

The XJ was designed at Jaguar Land Rover's Whitley plant in Coventry by a team led by design director Ian Callum.[14] Design work began in 2005, with final design approval taking place in November 2006 and the design being frozen in the first half of 2008.[15] [16] The new design is a complete departure from any earlier XJ model; mechanically, the car is a development of its predecessor.[17]

Models

In addition to the standard version with a 3035mm wheelbase, a long-wheelbase version was available with a 3160mm wheelbase.[7] At the 2010 Moscow Motor Show, a high security version of the car called the XJ Sentinel was introduced.[18] [19] This is an armoured version of Long Wheelbase XJ with B7-level ballistic protection as well as providing protection against 15 kg TNT or equivalent explosive. It has the 5.0 L supercharged V8 engine shared with the XJ Supersport having a power output of and 19-inch wheels with Dunlop Self Supporting Technology run-flat tyres.[20] Unlike other full-size flagship executive cars, the long-wheelbase variant was designed first and was expected to make up 67 percent of sales in the US market.[21]

Transmission and top speed

All 2010 models of the Jaguar XJ include standard six-speed automatic transmission with Jaguar Sequential Shift carried over from the X350, the main change being steering wheel shift paddles rather than the J-gate gear selector. The XJ has an electronically limited top speed of 250km/h; the limiter has been raised to 280km/h for the XJR model.[23] [24] An eight speed automatic transmission was introduced from 2013 onwards.[25]

Chassis

The XJ features a lightweight aluminium floorpan and body (with 50% recycled material content) based on the X350 chassis and retaining a proportion of the earlier floor pan. The biggest change is reversion to steel coil springs for the front suspension, retaining air suspension for the rear only. Continuously variable damping is electronically controlled as before but with driver selectable modes.[26] The aluminium alloy uni-body makes the XJ L among the lightest of the full-size executive saloons despite its exterior proportions, weighing in at 4131lb, which is 245lb lighter than the mid-size/executive BMW 550i.[21]

Equipment

Driver information and entertainment is provided by a Bowers & Wilkins 1,200-watt, 20-speaker Dolby 7.1 surround-sound system,[9] along with a bi-directional touch screen display on which the driver can only see the vehicle functions and satellite navigation data; a front passenger can simultaneously view a DVD movie or a television transmission.[26] Standard equipment levels on the United States-spec XJ L with the base engine includes a panoramic dual-pane moonroof, lane-departure warning, navigation, quad-zone climate control, and power sunshades, which is considered to be generous at this price point compared to other flagship executive saloons.[21]

Fuel economy and emissions

The diesel engine version had a fuel economy of better than and a emission rating of 184 g/km.

Special uses

The car has been used by British prime ministers. Dating back to the Jaguar XJ (Series III), various versions of the XJ were used by Margaret Thatcher, John Major, Tony Blair, and Gordon Brown.[27] On 11 May 2010, David Cameron took delivery of the dark grey car No. 10 Jaguar XJ Sentinel as his prime ministerial car.[28] In 2011, Cameron took the delivery of another XJ Sentinel featuring bomb proof doors, bullet proof glass, and armoured plating beneath the floor of the car, respectively replacing the previous XJ Sentinel.[29] The car was used for transporting Theresa May,[30] [31] and was also used by Boris Johnson.[32] Under Johnson, the XJ was replaced for the first time since 1979 by the Range Rover Abio Sentinel as the prime ministerial car in 2019.[33]

Models 2017-2019 received an upgraded 10" infotainment LCD, up from 7" LCD that was offered on all previous models.

Discontinuation

On 30 May 2019, Autocar reported that Jaguar would discontinue the X351 in July 2019, partly to make way for a new flagship XJ electric car planned to be built at Castle Bromwich.[46] The article mentioned that, despite its status, it was Jaguar's least popular model, selling 301 in September 2018 compared with 4,492 Jaguar F-Pace SUVs and 2,252 Jaguar XE saloons.[47]

In February 2021, it was announced that the electric XJ successor was cancelled for the present.[48] The company said: "Following a thorough technology review against the exponential change in the automotive industry, we concluded that the planned XJ replacement does not fit with our vision for a reimaged Jaguar brand."[49] As reported by Richard Porter of Sniff Petrol in August 2022, the prototypes of the cancelled successor still existed and were SORN,[50] and subsequently found out other prototypes existed and were still being tested on the road.[51]

In a September 2022 retrospective, James Howe wrote: "Fans of the XJ may regard the X351 as too far removed from the familiar flowing lines of its seven predecessors, but even 12 years after it was launched at the Saatchi Gallery in London, and two years since production ceased, it still looks modern and unmistakably Jaguar."[2]

The last XJ rolled off the production line in 2019 and at that point, it was announced that it would not get a direct replacement.
