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.

How Jaguar optimized the Ingenium gas engine for the F-Type

At the 2017 New York Auto Show, Jaguar showed off the new entry-level F-Type, packing a 2.0-liter, turbocharged, gasoline-fueled inline-four that produces 296 horsepower, which is built in-house in the UK. It's the debut of this branch of the Ingenium engine series, and it's also the top of the Ingenium gas range; most JLR vehicles will offer a less powerful 247-hp version. We caught up with Jaguar's engineers to figure out exactly how this high-output Ingenium engine differs, and what Jaguar had to do to fit it in the F-Type's engine bay. While all Ingenium 2.0-liter gas fours share major architecture – the aluminum block and heads, as well as the bore and stroke – there are some internal differences. The most important are the low-compression pistons, which allow for more boost without detonation. The new compression ratio is 9.5:1, compared to the 10.5:1 ratio in the 247-hp spec engines. To make the most out of more boost, you need new plumbing and a way to get more fuel into the combustion chamber. So Jaguar fitted a larger twin-scroll turbocharger that's unique to this application. It features low-friction ceramic ball bearings – Jaguar says this improves transient response. There are also new fuel injectors and a fuel pump to accommodate the increased demand for gas in the high-output engine. On the back end, there's a unique exhaust system with active flaps to give it a louder bark when called for. Of course, some new hardware and more boost means the various electronic systems that control the engine needed changes. For one, Jaguar's changed the cam timing and valve lift mapping, as well as the ignition timing. The throttle mapping and transmission calibration have also been optimized for the new engine.

As far as the driver's concerned, the biggest change from the 247-hp engine to the 296-hp one – other than increased scoot – will be where the power peak is. The 296-hp engine makes peak power at a higher point in the rev range, which should reward drivers who generously prod the throttle and hold gears in manual mode. Remember, F-Types equipped with this engine will only be available with an automatic transmission. You should also remember that it's an excellent gearbox overall, with rapid, smooth shift characteristics, if the other 8-speed Jaguars are anything to go by.

2018 Jaguar XJR575 First Drive Review | Everyone loves an underdog, right?

The number is right there, nestled smack in the middle against the windshield in red: 575. In case you missed it, there are another four red 575s stitched into the seat backs. You might excuse Jaguar for the numerical ostentation, but with manufacturers taking the horsepower arms race nuclear, the 6-year-old XJR sure could use a hook. What better way to stand out than an engine output humblebrag? The $122,400 Jaguar XJR575 gains 25 horsepower for 2018 thanks to software recalibration, which helps scoot the 17-foot-long four-door to 60 mph in a claimed 4.2 seconds. I'm gunning the XJR575 along the mountainous passes near the Alvao Natural Park in northern Portugal to find out whether the upgrade is enough to keep this underdog relevant in the fevered pitch of the high-dollar sedan market. Glance at the Jag in profile, and you might doubt its athleticism. Though nearly identical in length to a long-wheelbase BMW 7-Series and Mercedes-Benz S-Class (and 1.8 inches shorter than the Audi A8L), the XJR575's sloping rear window and rounder styling lend it a somewhat lazier, more lavish appearance. It's also long in the tooth, this design having been first introduced in 2009, but it wears its age surprisingly well. Frankly, you just don't see XJ-series Jags as often as their strong-selling competitors, and that keeps them looking fresher, somehow. In contrast, the Germans have kept their exterior lines purposeful and contemporary looking, with more frequent redesigns furthering their cause. Climb inside, and the XJR's premium trim lends a bit more modernity to the familiar cabin. For starters, the diamond-quilted and perforated leather seats offer solid support, but they might be a bit firm for long hauls. Unlike other XJs, the XJR and R-Sport trims don't offer a massaging feature, an unfortunate sacrifice that is available on most, if not all, of the competitive set. The rear quarters do, however, offer enough legroom for serious stretching out. Tall swaths of carbon fiber trim the door panels while another thin rim of carbon extends around the dashboard, a design shorthand for sportiness despite the fact that the XJR is only available stateside in long-wheelbase form. An Alcantara headliner aids the high-end argument. A few aging elements show cracks in the facade, among them the ungainly seams at the dashboard's center and switchgear that's grown more than a bit long in the tooth.
