Jaguar XE promises to net 'over 75 mpg,' just not for us [w/video]

With around a month away from its world debut on September 8, Jaguar continues to issue a constant drip of updates about its upcoming XE compact luxury sedan that's aiming to take on the BMW 3 Series and Audi A4. Where the company's last bit of info focused on the car's suspension setup, this time Jag's putting the spotlight on the new model's modular platform and making some big promises about it, too. How big? Try over 75 miles per gallon big.
That's the headline figure that Jaguar is claiming for its new sedan, but it's keeping mum on just what powertrain will realize that figure. Furthermore, that result is on the European test cycle, which is more lenient than America's EPA testing regime. In any case, when the XE hits the road, Jag says it will be the most efficient vehicle from the company, ever.
That's thanks in no small part to the aluminum-intensive monocoque chassis underpinning the sedan. It's constructed from a new grade of the lightweight metal called RC 5754 that uses a high portion of recycled material. "The Jaguar XE body uses over 75-percent aluminum content, which far exceeds any other car in its class. This gives us a body structure with unrivaled low weight: it's light but also immensely strong with extremely high levels of torsional stiffness," said Dr. Mark White, Jaguar Chief Technical Specialist; Body Complete.

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 likely moving HQ to Britain's most iconic racetrack

Jaguar Land Rover looks increasingly likely to make Britain's iconic Silverstone race track the automaker's new headquarters. There isn't a final deal in place yet, but the British Racing Drivers' Club, which owns the circuit, plans to have the membership vote on whether the negotiations should move forward, according to Autosport. BRDC leaders already presented the plan to members, and they were open to the idea. "The response was favorable so we will now set up an EGM for the members to vote and give the board a mandate to proceed with the deal and continue with the negotiations with JLR," BRDC president Derek Warwick told Autosport. There's no guarantee yet that JLR actually completes the deal. "There's still a lot of work to do to get the deal to where both sides are happy and more importantly what's right for the BRDC and its members." Warwick said. Rumors in early December suggested JLR was among the firms submitting bids to purchase the track, and the automaker allegedly offered 22.7 million pounds ($34.1 million at the time) for it. The company would also reportedly invest nearly $80 million to renovate the site, including adding a museum, experience center, hotel, and offices. The track would still be open for motorsport, too. Silverstone has hosted the Formula One British Grand Prix many times over the decades, and organizers signed a 17-year deal in 2009 to keep things that way well into the future. Series like the FIA World Endurance Championship, MotoGP, and British Touring Car Championship also compete there. Related Video:
