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 Land Rover offers (some) detail about new Ingenium engine

Jaguar Land Rover officially announced its Ingenium family of engines with the unveiling of the 2.0-liter version in the Jaguar XE concept at the 2014 Geneva Motor Show, but it kept details very thin at the time. All we knew was that the new turbocharged mills could be configured to use gasoline or diesel, and be positioned longitudinally or transversely. Months later, JLR is finally letting some more info slip about its new baby, but there are still some big questions to be answered.
For the Ingenium project, Jaguar Land Rover gave its engineers a clean sheet of paper and told them not to worry about using any previous parts or machinery. In the end, the designers came up with a family of turbocharged, aluminum-block engines based around modular, 500cc cylinders to allow it to grow or shrink as the market demanded. The layout was also made adaptable enough to incorporate hybrid drivetrains, if needed. "Being configurable and flexible are the two key strands of Ingenium's DNA because we have future-proofed our new engines from the outset," said said Ron Lee, the company's director of Powertrain Engineering.
To maximize efficiency, Jaguar promises that all versions of the Ingenium engines come with computer-controlled, variable oil pumps and water pumps to use only as much energy as needed. They also get direct injection, roller bearings for the cams and stop/start. The diesel version alone has 17 percent less internal friction than the mill it replaces, the company claims. JLR is also promising class-leading figures for Ingenium's torque and horsepower too, but it's not giving away those specs just yet.

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.
