With sales down, Jaguar is just relentless with their publicity and press releases. They have just announced that another XF variant will enter the Jag lineup. It will be a supercharged version that would pack a whopping 470 horses.

Power will come from a supercharged 5.0 L AJ-V8 Gen III engine that was showcased in last Detroit Auto Show. The 470hp boasts of a 12% increase over the 4.2L XF and can generate 424 lb/ft of torque. This gives the car a not-at-all slow 0-60 mph time of 4.9 seconds.

Aside from the beefed up engine, the car will also feature a computer-controlled variable damping system, an e-differential, ventilated disc brakes, and new bits of trim. Surely you can just slap on a supercharger and not do anything about braking and handling. A few added touches inside won’t hurt as well.

“The Jaguar XF Supercharged will offer consumers a compelling luxury sedan choice with benchmark handling ability and truly memorable performance,” says Mike O’Driscoll, Managing Director, Jaguar Cars. “This new luxury performance XF Supercharged sedan builds on the tremendous momentum Jaguar has achieved by introducing beautiful fast cars such as the XK sports car, the XF and the XKR and XFR models.”

The XF Supercharged is set to go on sale this October and MSRPs starting at $68,000.

Jaguar has just launched the first Jaguar XF intended for police use in the United Kingdom, and it is currently undergoing evaluation by law enforcement forces nationwide.

The police-spec XF is based on the diesel S trim, which makes the car good for 271 brake horsepower with the standard 3.0-liter engine. For this edition, a roof-mounted light bar and flashing LED lights around the car are all standard fare. There’s also a Home Office-specification ‘police pack’ that supply power to the car’s electronic equipment such as emergency lights and the radio.

“Police forces are looking for vehicles that represent value for money, have good environmental credentials and deliver the power and performance required of a pursuit vehicle,” said Jaguar’s UK managing director Geoff Cousins. “The police officers driving pursuit vehicles demand a very high level of performance and handling, as well as safety and comfort.”

Looks like the UK police will continue pursuit in style. This looks good on paper, starting from the fact that it’s Jaguar, which is British-made in contrast to the crop of BMWs that some of the plod currently use.

There’s a new Jaguar on the prowl and it’s running on Satan’s fuel (according to Clarkson) – namely, the Jaguar XF Diesel S, tagged as the most advanced and perhaps most powerful diesel Jaguar yet. Jaguar Cars Managing Director Mike O’Driscoll said that the XF Diesel S is “the best of both worlds”, citing the car’s high performance along with great mileage and emission levels.

The XF Diesel S is equipped with a 2.7-liter 275PS engine. This allows the car to go from 0-60 in 5.9 seconds. There is also a 3.0-liter 240PS engine variant available. What’s equally impressive is that the 2010 Jaguar XF Diesel S has a combined average mileage of 42 mpg, a 10-percent improvement for the 2.7-liter engine. The car also posts an improved 179 g/km CO2 emission rating.

Additional features of the car include 19-inch wheels, a boot lid spoiler for added aerodynamics, and new sequential turbochargers. Ron Lee, the chief engineer for the car’s powertrain, said that the new turbocharger “delivers V8 levels of performance from very low revs. It’s a power unit that offers superb flexibility and remarkably low fuel consumption and emissions, while building on the refinement that has become a trademark of our Jaguar diesel engines.”

Edmund’s came up with another head to head to head to head comparison. This time with mid-sized sports sedan featuring the Jaguar XF Supercharged, the BMW 550i, Mecerdes-Benz E550 and Audi A6. They took into consideration performance, handling, styling, price, and some of the bells and whistles that come with the cars. To round up, here are giblets of numbers for each of the cars.

• Jaguar XF Supercharged: 4.2L V8, 420 hp, 408 lb-ft of torque, 0-60 at 5.1 seconds.
• BMW 550i: 4.2L V8, 360 hp, 360 lb-ft of torque, 0-60 at 5.4 seconds.
• Mercedes-Benz E550: 5.4L V8, 382-hp, 391 lb-ft of torque, 0-60 at 5.4 seconds.
• Audi A6 4.2: 4.2L V8, 350 hp, 325 lb-ft of torque, 0-60 at 5.8 seconds.

Jaguar has had received a lot of negative criticism over the years. Probably the horrible styling of recent models. Probably its the performance that can be put to shame by some other entry-level car. And those are some of the things that their XF line is trying to do.

The 2009 Jaguar XF Supercharged is powered by a supercharged 4.2 liter V8 engine producing 420 hp with a max pull of 408 lb-ft mated to a 6-speed automatic transmission with Jaguar’s Sequential Shift accessible via flappy paddle shifters. 0-60 is achieved in a little over 5 seconds. Edmunds got a piece of some Jaguar XF action and they’re glad to show us some of the good stuff.
