Ian Callum, Brian Johnson and Lord March pick 10 top Jaguars

An automaker with as rich a heritage as Jaguar is bound to create a few experts along the way... and some divergent opinions, too. So on the eve of the debut of the new XE, Jaguar brought together three experts to whittle down the long list of classic Leaping Cats to just ten.
For this gargantuan task, it brought in Ian Callum (who, as the company's chief designer, knows a thing or two about Jaguars), Lord Charles Henry Gordon-Lennox (the Earl of March and founder of the Goodwood Revival) and Brian Johnson - who may be better known as the frontman of AC/DC, but also a classic car enthusiast, collector and racer in his own right.
So what did the designer, the nobleman and the celebrity choose? The SS100, XK120 (namely number NUB 120), the C-Type that competed at the 1953 Mille Miglia, the D-Type that won at Reims, the Mk II sedan, the E-Type that served as the Geneva show car, the one and only XJ13, company founder Sir William Lyons' personal XJ6 S1, the TWR XJS touring car and the 1988 Le Mans-winning XJR-9.

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 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.
