This classic Jaguar XJ has a 720-hp ungentlemanly secret

Forget Tawny Kitaen. If you want to make a Jaguar XJ rock, just do what this guy did: stuff a heavily modified and turbocharged General Motors V8 under the hood, and take it to the track.
The video calls this Series 1 XJ a sleeper, but with its open exhaust and obvious turbo whistle, the once-gentlemanly sedan is anything but. The owner says that the engine is GM LQ9 V8 that has been stroked to 402 cubic inches putting out around 720 horsepower with 12 pounds of boost (in standard form, this 6.0-liter V8 was used in the second-gen Cadillac Escalade). Check out the video below to see what that kind of power does for this classic Jaguar in the eighth-mile.

Latest Jaguar XJ snaps show old versus new

It is a rare day when automakers line up their current models and test cars right next to each other and allow us to compare them directly. However, Jaguar ending up doing just that during cold weather testing of the face lifted XJ, providing the perfect chance to see just what the company is changing.
We spotted the refreshed XJ testing last year, and it hasn't evolved much since then. The updated model sports clear turn signals and a slightly revised front air dam. The modifications are similarly minor at the rear. The bumper appears to dip down slightly further on the new sedan. Thankfully, those gorgeous taillights are still draped over the back of the car. The exhaust outlets have switched to oval shapes rather than the current parallelograms. This alteration could just be chalked up to it being a test car, but the previous tester we saw had a similar design. It's possible that the camouflage could be hiding other revisions, but don't expect anything radical from the facelift.
Our previous report indicated that Jaguar is also planning some interior upgrades with new infotainment and ambient lighting. The company seems to feel that there isn't a point in messing with the XJ's design just yet, since all of the changes we see here are very subtle. No problems, here - to our eyes, the big Jag is still one of the prettier sedans on the road today.

Jaguar F-Type greets US, shows off range of personalization

While the debut of the XFR-S is likely fresh on everyone's minds and browser windows, the other big story of late at Jaguar is the F-Type coupe and convertible. Originally unveiled in Paris, the LA show was the first opportunity that the sub-XK performance machine will be seen Stateside. However, it was not just the same news that we first heard in Paris, as Jaguar used LA to showcase its newly available "Black" design pack.
This styling package includes gloss black finishes for the grill surround, side vents, a flat-bottomed sport steering wheel, gloss black interior touches, and instrument panel rings. This package is available with Ultimate Black, Polaris White, Italian Racing Red, Rhodium Silver, Grey and Firesand (seen above) body colors.
The Black pack can be had on either the 3.0-liter supercharged V6 model, or the 5.0-liter supercharged V8 version. Specific additional "Black" tweaks are available based on which derivative you select. Specifically, a gloss-black rear valence is a V6-only modification.
