Is the Jaguar XFR-S really worth $17k more than the XFR? [w/poll]

Adding performance to a car is rarely cheap - whether you're looking to do it yourself or rely on the factory to do it for you. In the case of the new Jaguar XFR-S, the cost differential over an already-impressive (and somewhat expensive) XFR is a stout $16,800. Auto Express recently got a hold of both cars to see whether that price pays off on the track.
For that price, Jaguar gives the XFR-S an extra 40 horsepower and 41 pound-feet of torque - for a total of 550 hp and 502 lb-ft - to go with a stiffer suspension, beefed-up differential and, of course, meaner styling. We don't want to ruin the results of the AE video, but right off the bat, the host says that you can feel the extra power of the XFR-S, but that it's not a "night-and-day difference."
Scroll down to see what happens when two high-powered Jags go head-to-head on a track. And then be sure to let us know whether or not you think the added money is worth it for the XFR-S in the completely informal poll below.

Jaguar readying a pop-top F-Type Coupe? [w/poll]

Typically convertibles are spun off of coupes, but sometimes it goes the other way. Like the Porsche Cayman that was based on the Boxster, the Lotus Exige spun off of the Elise, and the Jaguar F-Type, which arrived as a roadster before the coupe debuted. But if the latest reports are to be believed, Jaguar could be planning something in between.
According to Auto Express (which has, mind you, been known to stretch the rumors out some), Jaguar is toying with the idea of offering a partial convertible version of the F-Type - something Porsche would call a Targa (and which we would too if Stuttgart weren't so litigiously protective of the name). The additional roof configuration would give the F-Type three body-styles, giving its customers more choices.
It wouldn't be the only sports car to offer three roof options: There's the Porsche 911, of course. Ferrari once offered GTB, GTS and Spider versions of the 348 and 355. The Chevy Corvette has been offered in all three forms, as was the Pontiac Solstice many moons ago. But that kind of variety in roof configurations has become scarce. Jaguar's decision reportedly depends on whether it can make the business case or not. Do you think there'd be enough demand for a lift-roof F-Type?

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.
