We’ve already broght you news of the new Jaguar XJ AWD on the news pages at www.europeancarweb.com and we have additional news about updates for the XF and XK models as well.
For 2013, the XF gets two new forced-induction powertrains – one is a 240hp 2-liter turbocharged four-cylinder that returns a very respectable 29mpg highway.
The technologies including direct injection, a low-lag turbo and variable valve timing on both the intake and exhaust cams. It also delivers 251 lb-ft of torque from 2000-4000rpm.
The second new engine is a 340hp supercharged 3-liter V6 replacing the naturally aspirated 5-liter V8, with which it shares the same basic architecture and technology. It provides performance comparable to the 5.0, such as 0-60mph acceleration in 5.7sec, but with better fuel efficiency (EPA-estimated 28mpg highway for RWD) and a 16000-mile/12-month service interval.
The V6 version will also have Jaguar’s news Instinctive All-Wheel Drive system to aid traction as well as a new eight-speed ZF automatic transmission, that will appear on all models to bring them in line with the latest offerings from other luxury manufacturers.
The AWD system has active power transfer technology that combines all-season traction with sporting agility and RWD steering feel. This is possible because in dry conditions, the electronically controlled wet multi-plate clutch sends a small amount of "pre-load" torque to the front wheels as the vehicle pulls away. It then sends most torque to the rear wheels once underway. The Instinctive AWD can transfer up to 50% of available torque to the front wheels, either in response to slip or to pre-empt rear-wheel slip. So in Winter mode, the system sends more "pre-load" torque to the front wheels before switching to a 30:70 torque share to maximize traction on slippery surfaces.
Additionally, there’s an Auto Stop/Start feature for the supercharged V6 and V8 models that will again improve fuel efficiency from these powerful engines.
The Speed Pack option that was recently introduced for the XJ is now offered on the XFR. It includes suspension and aerodynamic enhancements in order to unlock the top speed limiter, allowing the car to reach up to 174 mph.
Furthermore, there are improvements to the navigation and infotainment system, with new premium audio systems from Meridian.
