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 releases C-X75 concept build story

If you want to know what was going through the minds of decisionmakers at Jaguar when the company decided to build the batty C-X75 Concept, look no further than the quick video after the jump. Jaguar set about building a car with the performance of a Bugatti Veyron, the electric range of a Chevrolet Volt and the emissions of a Toyota Prius, and they turned to a legendary engineering firm to help make it happen. Williams, the same crew behind Williams F1, helped Jaguar stitch the concept car together, and the result is unlike anything we've seen before.
The twin-charged 1.6-liter four-cylinder mounted amidship is paired with an electric motor at each wheel for a combined output of over 850 horsepower. And, since the whole chassis is hewn from carbon fiber, a production version would've been light enough to give machines like the McLaren P1 and Ferrari LaFerrari a run for their money. Shame they apparently couldn't make the business case work. Watch the concept build story in the video below for yourself.

Stunning Jaguar E-Type Lightweight tribute featured by Petrolicious

This is a Series 1 Jaguar E-Type Coupe. Enzo Ferrari, Il Commendatore himself, called it "the most beautiful car ever made." It can count among its owners Steve McQueen, Brigitte Bardot and a number of other celebrities from the 1960s. It remains one of the prettiest and coolest cars ever.
While we don't normally prescribe to modifying classics like the E-Type, cars that are used for vintage racing, like this particular example, are certainly the exception. It's owned by Jason Len and is the subject of the latest video from the team at Petrolicious.
Len's 1964 E-Type has been fashioned to look like one of the rare Lightweight E-Types from 1963 and 1964. The aluminum-bodied E-Types, of which only a dozen were built, were all intended exclusively for racing, much like Len's heavily modified example. While it retains the 3.8-liter straight-six, its engine, transmission, suspension, brakes and body have been extensively tweaked and fettled to allow this classic Jag to compete with a field of V8s.
