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 F-Type US order guide loose online

An alleged US order guide for the 2014 Jaguar F-Type has made its way online courtesy of the good people at F-TypeClub.com, documenting everything from wheel color options to special equipment packages. From the looks of things, buyers will be able to choose from a total of eight wheel designs in sizes ranging from 18 inches on the base model all the way up to 20 inches. While most of those rollers are available in either silver or black finishes, the 20-inch blade-style wheels are not only forged, but come with carbon-fiber trim. Fancy.
Depending on trim, F-Type buyers will get to choose between two types of seat, including a set of performance-style 14-way power adjustable thrones, complete with seat belts in black, red or tan. Other fun tricks include available power folding side view mirrors and a 770-watt, 14-speaker Meridian sound system.

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.
