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.

Is Jaguar's 3 Series-fighter the brand's last chance?

The upcoming line of compact 3 Series-fighters from Jaguar, often referred to as the Jaguar XS, could consist of a sedan, wagon and possibly a coupe and GT model (think BMW 5 Series GT). The car's all-aluminum architecture also will provide the basis for two new sports utility vehicles. Just how important is the much-touted "baby Jag" project to parent company Jaguar Land Rover? A JLR executive reportedly says the brand's survival is directly linked to the success of the XS, codenamed X760, Autocar reports.
The brand's survival is directly linked to the success of the XS.
"If the X760 fails, it will probably be the end for the [Jaguar] brand," the executive says. But Adrian Hallmark, Jaguar's global brand director, claims Jaguar will "build the most advanced, most efficient, most refined car in that [compact luxury sedan] segment. Not almost as good as, but better than the best in the world."

Jaguar Project 7 concept is an F-Type in a D-Type mold [w/video]

In addition to the XJR, XFR-S and XKR-S GT models Jaguar is bringing to the Goodwood Festival of Speed this weekend, the manufacturer announced that the F-Type-based, D-Type-inspired Project 7 design study will make its "dynamic" debut at the festival, with driving duties assigned to Mike Cross, Jaguar's chief engineer of vehicle integrity. Here's the cool part: With Jaguar's Director of Design, Ian Callum, leading the team responsible for Project 7, it went from the drawing board to track testing in only four months, Jaguar states, with a claimed 0-60 time of 4.1 seconds and top speed of 186 miles per hour.
Project 7, which was named in honor of Jaguar's seven wins at the 24 Hours of Le Mans, will be making runs up the hill at Goodwood over all three days of the festival, which starts at the Goodwood House in West Sussex, England, this Friday.
Far from a fragile concept car, Jaguar says, the single-seat Project 7 is a fully functional sports car. It uses the all-aluminum chassis and body of the F-Type, retains that car's 550-horsepower, supercharged 5.0-liter V8 and eight-speed automatic transmission but features lots of bespoke carbon fiber aerodynamic bits, some of which were inspired by the Le Mans-winning D-Type of the 1950s. The most obvious nod to that classic is the rear fairing with integrated rollover hoop - the F-Type's convertible top is gone. The windshield was also lowered, giving the roadster a more rakish silhouette as it sits on 20-inch forged-alloy wheels with carbon fiber inserts.
