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 vs. Jetman: Place your bets

As many car-versus-jet races as we've seen on video, we never seem to tire of them. This latest one, however, doesn't so much pit a car against a jet airplane, per se, but a guy in a jetpack against a supercharged Jaguar. That in and of itself might make this clip worth a watch. The guy in question is one Yves Rossy, otherwise known as the Jetman. The Swiss air force aviator developed, wears, and pilots a six-and-a-half-foot-wide fixed wing fashioned from carbon fiber and fitted with four jet turbines strapped to its underside, each good for 88 pounds of thrust. He's flown it over the Alps, across the English Channel, and above the Grand Canyon, but now he faces off against another adversary. That, of course, would be the Jaguar XJR, complete with 5.0-liter supercharged V8 good for 550 horsepower. Piloting the performance sedan is none other than Martin Brundle, a former F1 driver, Le Mans winner, and television commentator. The two line up on and above a 1.75-mile stretch of road in the deserts of Dubai for the showdown. We could tell you who won, but you'll want to watch the video above for yourself to find out first-hand. And if you want to know more about the Jetman and his amazing flying creation, watch the video below.

Brundle, who drove in F1 alongside Michael Schumacher and is now a commentator, had the new all-aluminium 550PS, 5.0-litre Supercharged V8 Jaguar XJR at his disposal while Rossy was strapped to his 2m-wide fixed wing, powered by four Jet-Cat superchargers. The race took place on a closed private road and in the skies above it, and was captured in a three-minute short film.
