2016 Jaguar XF mule spied in Germany

From our best guess, the Jaguar test mule shown in these spy shots could very well be our first glimpse at the next-generation Jaguar XF, due out around the 2016 model year. The current XF has been around for five years already (launched in 2008), and this mule is likely testing powertrain or chassis components for a new version of the midsize Jaguar sedan.
With what seems to be a stretched wheelbase and wider track, this is almost certainly not a mule for the 3 Series-fighting Jaguar XS. That being said, though, there is also the outside chance that this could be a mule for other future Jaguar Land Rover products including a production version of the Jaguar C-X17 crossover or the Jaguar-based Range Rover Grand Evoque. Only time will tell what these images truly foretell, but if nothing else, it proves that Jaguar is definitely staying busy these days.

Jay Leno hits the road in a 1951 Jaguar XK 120 Hot Rod

The 1951 Jaguar XK120 featured in this episode of Jay Leno's Garage might look vaguely like a classic Jag roadster at first, but underneath this cat is something completely different. It was built by Leno's buddy Jason Len of XK's Unlimited when he grew tired of keeping these convertibles stock, and this aluminum-bodied beast was the result. Practically the only major Jaguar part left is the engine. It's a tuned 3.8-liter inline six from an E-Type with Weber carbs that makes an estimated 300 horsepower out of some gorgeous side-exit exhausts. The mill is backed up to a BorgWarner five-speed manual. However, the big surprise is the chassis. In place of Jag's original solution, Len has a custom tubular space frame that he claims sheds some 1,000 pounds over the stock example. There are still some classic Jaguar touches left, though, such as the fin over the driver's head that is reminiscent of the D-Type, and both the wheels and gauges are replicas based on that classic racer. Of course the best part is watching Jay drive this Jag hot rod. This big cat really knows how to purr.

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.
