| Predecessor | Jaguar XK8 |
The Jaguar XK (project code X150) is the second generation of the Jaguar XK. The vehicle was unveiled in 2005 at the Frankfurt Motor Show with the first generation's 4.2 V8 engine. The XK convertible was unveiled in 2006 North American International Auto Show in Detroit. A facelifted XK was launched in 2009 with a new 5.0 L V8 engine.
Design
The X150 design was based on Advanced Lightweight Coupé (ALC) which was first seen at the 2005 North American International Auto Show. The designer, Ian Callum, was also responsible for the Aston Martin DB7 and Vanquish coupés. The new XK's grille is inspired by that of the 1961 Jaguar E-Type.
The XK received a facelift in 2009 (known as 2010 models in the US)[1] with minor alterations to front and rear lighting and bumper designs, together with the introduction of a new 5.0 L V8 for both the naturally aspirated XK and the supercharged XKR. The interior also received some changes, in particular the introduction of the XF style rotary gear selector mated to the new ZF automatic transmission.
The range was extended in 2011 with the introduction of the new XKR-S at the Geneva Motor Show, featuring an upgraded XKR engine producing 550 PS (405 kW; 542 hp)[2] and torque of 680 N⋅m (502 lb⋅ft). The XKR-S badge was first used on the 2008 special edition XK. Jaguar claimed that this new version is the fastest production Jaguar ever, a top speed of 186 mph (299 km/h) and acceleration from 0 to 60mph in 4.2 seconds (0–100 km/h (62 mph) in 4.4 seconds).
The XK received a second facelift in 2011 with new front bumper and light design[3] and was presented at the New York Auto Show as a 2012 model.

Transmission

Safety
The new XK introduced a world first in pedestrian safety, PDBS (Pedestrian Deployable Bonnet System). In many pedestrian collisions with vehicles, head injuries occur when a pedestrian's head hits the bonnet of the vehicle. The injuries are usually sustained from the bonnet deforming and the pedestrian's head colliding with the engine block underneath rather than the bonnet itself.
Jaguar's innovation is to have sensors in the front bumper that determine if a pedestrian has indeed been struck and this then triggers two pyrotechnical charges that instantaneously lift the bonnet, providing extra distance between engine and head. The hood's sheet metal cushions the impact better than the solid engine block.
