Jaguar envisions future without V8 engines

With tighter emissions and fuel economy regulations looming, Jaguar may have to do more than make a small, fuel-efficient hatchback to lower its model range's consumption figures - it also might give up its venerable V8 power, Drive reports. But not anytime soon, says Steven de Ploey, Jaguar's product and marketing director, who recognizes that the V8 can be replaced only by something that offers the same, or better, performance. But he has a word of caution: "We are not wedded to V8s."
In the meantime, de Ploey says there are other ways to reduce emissions. One of the first steps Jaguar could take is to shift away from the use of superchargers, which aren't as good as turbochargers at maintaining efficiency and making power. But he adds that supercharging still is "at the heart of Jaguar's performance proposition," and that the company has addressed the current downsizing trend by "replacing our naturally aspirated V8 with a 3.0-liter supercharged V6."
Consider one of de Ploey's comments on the cancelled C-X75 supercar (pictured) for some clue about Jaguar's future: "Some of the stuff we have already exploited to the extreme in the C-X75 is the kind of thinking for us and is an essential test bed to see how we could evolve from today to something that is sustainable in the future."

Jaguar previews XF sedan ahead of New York debut

Jaguar is in the midst of an aggressive product expansion, with the new F-Type taking it back into sports-car territory, the upcoming F-Pace putting it in the crossover market for the first time and the XE renewing Jag's assault on the entry-level luxury-sedan segment. But it hasn't forgotten about its core models. The British automaker has a new flagship XJ under development, and Jag will showcase a brand-new XF at the New York Auto Show next month. But before it does, Jaguar has given us something to chew on with these teaser images: one showing the new sedan from above, and one showing the new cockpit. Now it may be hard discern much from that overhead view – which is not a typical teaser – but it's clear the new XF will feature more sharply creased body lines and a large panoramic sunroof. Meanwhile the interior looks like a modern update of the current model, borrowing some elements from the smaller XE. There's a wider infotainment display, the rotary knob for the transmission has moved toward the center, some (but not all) of the air vents appear to hide away when not in use, and there's a sportier steering wheel – though we do appear to be looking at the more performance-oriented S model. The XF, for those having trouble keeping track, is Jaguar's challenger to the likes of the Mercedes E-Class, BMW 5 Series, Audi A6 and Maserati Ghibli. It was introduced in 2007, and has been available (in certain markets anyway) in sedan and wagon forms, with engines ranging from a 2.0-liter turbo four with 240 horsepower all the way up to a 5.0-liter supercharged V8. With the New York show fast approaching, we won't have to wait much longer for a complete view of the new XF. But even before then, Jaguar promises to reveal the new XF in dramatic fashion in London: on March 24, it will drive the new sedan on two wires barely more than an inch thick suspended high above the river.

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.
