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 F-Pace will debut in Frankfurt

Jaguar makes sports cars and it makes luxury sedans, but it is set to expand into new territory altogether at the Frankfurt Motor Show this coming September. That's where and when it will reveal the F-Pace, Jaguar's very first crossover, and the production version of the C-X17 concept pictured here. Developed with critical input from sister-company Land Rover, the Jaguar F-Pace is being billed as a "sports crossover," with a more on-road focus than the SUVs of its off-road counterpart. Expect a range of engines to draw principally off of the new Ingenium family of four-cylinder gasoline and diesel powerplants, capped by Jag's signature supercharged V6 – just like the new XE sedan with which it will share much of its underpinnings. We can always hope, though, for an even more potent SVR version to follow with the JLR's sensational 5.0-liter supercharged V8. The Frankfurt reveal will mark two years since the C-X17 concept was first presented at the same show in 2013. Its arrival, coupled to that of the aforementioned XE, promise to push Jaguar's global output up from around 80,000 units last year to more than 200,000 once both models hit their stride.
