2014 Jaguar XFR-S super sedan is 550-HP worth of cool

The 2014 Jaguar XFR-S was considered last year, teased last week and now has been totally let loose. The most powerful sedan the company has ever made and the newest addition to its line of R-S performance cars - following the XKR-S - and we'll be getting even fewer of them than we thought. 200 had been the rumored allotment for the US, but the official word now is that we'll see just 100.
Each XFR-S will use the same 5.0-liter supercharged V8 that powers the XKR-S, meaning a 40-horsepower and 41-pound-foot bump over the XFR for 550 hp and 502 lb-ft in total. Shifting through the adaptive, eight-speed ZF transmission gets it from standstill to 60 mph in 4.4 seconds, but for all that, it gets the same gas mileage as the XFR, aided by its stop/start system, and so doesn't get hit with a gas guzzler tax.
Other XKR-S bits have made the jump, including an upgraded suspension front and rear, the near-straight pipes for the cracking exhaust note we drank up like ambrosia and twenty-inch, six-spoke lightweight wheels that are an inch wider than on the XFR. Lateral stiffness is up 30 percent, the electronic systems have been recalibrated to handle the extra oomph, throttle response has been sharpened and can be made even sharper by going into Dynamic Mode.

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.
