Chronology
PredecessorJaguar XJ (X358)

The Jaguar XJ (X351) is the latest Jaguar XJ luxury saloon from Jaguar Cars. Completely new styling combines with underpinnings based on the previous X350 version.

Launch

Jaguar Land Rover invited Jay Leno to unveil the new XJ during the launch at the Saatchi Gallery in London on 9 July 2009.[3] The unveiling was broadcast live on the Jaguar website. US model was unveiled in 2009 Pebble Beach Concours d'Elegance.[4]

Production of the car was due to begin in September 2009, with first deliveries being made in early 2010.[5] However, the sale was delayed to December.[6]

On 11 May 2010, the Prime Minister of the United Kingdom took delivery of a long wheelbase, armoured, dark grey XJ as the official state car of the United Kingdom.[7]

Design

The XJ was designed at Jaguar Land Rover's Whitley plant in Coventry, by a team led by design director Ian Callum.[8] The new design is a complete break from any earlier XJ although mechanically the car is a development of the previous version[9]

Specifications

Models

In addition to the standard version with a 3,035 mm (119.5 in) wheelbase, a long wheelbase version is available with a 3,160 mm (124 in) wheelbase.[3] However, unlike other full-size flagship luxury cars, the long wheelbase variant was designed first and is expected to make up 67 percent of sales in the United States market.[10]

Transmission and speed

All 2010 models of the Jaguar XJ include standard 6-speed automatic transmission with Jaguar Sequential Shift carried over from the previous car, the main change being steering wheel paddles rather than the "J" gate. The car has an electronically limited top speed of 155 mph.[11][12]

Chassis

The XJ features a lightweight aluminium floorpan & 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 electronically controlled as before but with driver selectable modes.[13] The aluminum alloy uni-body makes the XJL among the lightest of the full-size luxury sedans despite its exterior proportions, weighing in at 4,131 pounds, which is 245 pounds lighter than the mid-size/executive BMW 550i.[14]

Equipment

Driver information and entertainment is provided by a Bowers & Wilkins 1200-watt, 20-speaker Dolby 7.1 surround-sound system [5] and a bi-directional touch screen display - on which the driver can only see the vehicle functions (and satellite navigation data), but a front passenger can simultaneously view a DVD movie or a television transmission.[13] Standard equipment levels on the United States-spec XJL 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 luxury saloons.[15]

Fuel economy and emissions

The diesel engined version will have a fuel economy of better than 40 miles per imperial gallon (7.1 L/100 km; 33 mpg‑US) and a CO2 emission rating of 184 g/km.[1]

Production

The vehicle is produced at the Castle Bromwich Assembly plant in Castle Bromwich, UK.[16]
