2013 Jaguar XFR-S

Why Ask Questions When You Already Know The Answer?
"Is it fast?"
We get that question a lot. Several times a month, in fact, and it comes from every corner of our lives - friends, family, complete strangers and even colleagues from time to time. And it's an understandable query. After all, speed, either in a straight line or around a twisty bit of tarmac, is a universally accepted line of demarcation between the typical family sedan and something much more fun and therefore desirable.

2013 Jaguar XF 3.0 Supercharged

Generally speaking, I don't get too upset about the growing need to replace displacement in modern cars. Sure, there are exceptions (don't you touch my 6.2-liter AMG V8), but honestly, the industry's new forced induction powertrains are all lovely, and their gains in fuel economy - when they actually make good on them - can make up for the ever-so-slight losses in performance or driving character.
But I'm having a hard time keeping my chin up with this Jaguar XF. For the 2013 model year, Jaguar has killed off the naturally aspirated 5.0-liter V8 and fitted a supercharged 3.0-liter V6 with an eight-speed automatic in its place (and even offers a turbocharged four-cylinder engine below that). That all sounds perfectly well and good, but a week behind the wheel of this British Racing Green sedan just left me missing that V8. And then some.

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.
