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.

2016 Jaguar XJ sedan revealed

Jaguar has been steadily updating its sedan lineup, launching the entry-level XE and a new version of the mid-range XF – and now it's revealed an refreshed version of its flagship XJ. A facelifted version of the existing model (which was first launched in 2009 and arrived in the US in 2011), the 2016 Jaguar XJ benefits from a few key enhancements to keep it current. The principal visual updates revolve around the exterior lighting, which now includes full LED headlights, new daytime running lights and redesigned LED tail lights. There are new oval exhaust tips as well, but some of the most vital updates have been carried out inside. The refreshed interior includes a new InControl Touch Pro touchscreen infotainment system, with multi-touch control and backed up by a 60-gig solid-state hard drive. A new 17-speaker Meridian sound system comes standard, and the instrument cluster has been redesigned as well. The XJ also benefits from Jaguar's All-Surface Progress Control system and a raft of driver assistance features. Rear-drive models also get a new electric power-assisted steering rack and semi-automated parking system. Between engine options, drivetrain choices, wheelbase lengths, and trim levels, the updated XJ continues to offer an array of configurations – and Jaguar has worked to further differentiate them from one another. The base model carries the 340-horsepower, 3.0-liter, supercharged V6 and can be specified with rear- or all-wheel drive. There are regular and long wheelbase versions, and in R-Sport and Portfolio trim lines (the former now coming standard in the shorter car). Though the entire range is supercharged, the model designated as the XJ Supercharged packs a 470-hp version of the company's celebrated 5.0-liter force-fed V8, while the performance flagship XJR packs the same engine but with 550 hp (once again in either wheelbase) and now comes standard with the Black Pack. The 2016 Jaguar XJ is slated to reach US showrooms this fall. The updates will surely go a long way towards keeping Coventry's flagship sedan in the game for longer until an all-new model is ready. The question is whether these updates will be enough to keep the XJ competitive against the newer BMW 7 Series, Mercedes S-Class, and Maserati Quattroporte. Or for that matter with the Audi A8 that's just as old but was also recently refreshed, or the Lexus LS that's been around for longer with similar updates along the way.

Jaguar F-Pace V6 reminds us why we love supercharged engines

There are many things we like about our 2018 Jaguar F-Pace long-term car, as well as some things we don't care for, but easily one of the best things about it is the engine. Under the hood is the 380-horsepower supercharged V6 that Jaguar offers on other models. That amount of power would be fun in just about any car with any engine, but there are specific reasons why this particular engine is special, and it's because of that supercharger. Supercharged engines have a very different character than increasingly common turbo engines. One of the most noticeable differences being engine response. Unlike turbo engines, the F-Pace's V6 feels hardwired to your foot. Every extra millimeter of pedal travel yields a slightly greater amount of tug. And the tug is felt immediately. Even the best turbo engines have a hard time recreating this response. The power band is very linear, as well, so you know exactly what you're getting every time you hit the gas. The engine is wonderfully torquey, too. Because the Jaguar's engine uses a classic Roots-type blower, there's a major improvement in low-end torque. This means that our F-Pace has loads of grunt for punting around at low-rpm and can seriously move when tromping on the gas. And because of the near-instant throttle response and linear power band, it doesn't slam you in the back unexpectedly like some turbo engines do. Despite how great these supercharged engines are to experience, we're concerned that supercharged engines like this may disappear in all but ultra-limited production, high-performance cars such as the Chevy Corvette Z06 and Cadillac CTS-V. The reason being that car companies have to keep making cars more fuel efficient and lower emitting. Putting a supercharger on an engine is adding a handicap, since it takes engine power to spin the belt-driven supercharger. And when a turbo, which uses wasted energy from exhaust gas to spin the compressor and built boost, can effectively do the same thing, it's hard to make a case for a supercharger. We won't give up hope completely, though. Mazda is using superchargers on its spark-assisted compression ignition gasoline engines. And while we're not sure how powerful and sporty those will be, Mazda has said that it's going with superchargers for exactly the reasons we like the Jaguar engine: smooth power and fast throttle response.
