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.

2016 Jaguar F-Type S Coupe Quick Spin [w/video]

The Jaguar F-Type – as either a coupe or a convertible – has proved easy to fall in love with. It's one of the best looking cars in the world, period. And it has been endowed since launch with lovely engine options on either end of the range, athletic rear-drive handling, and a tuneful exhaust that sets one's heart to thumping. So how does Jaguar improve on such a winning formula? The answer that enthusiasts have hoped for is that Jag offer its sports machine with a traditional manual gearbox. And for the 2016 model year, those hopes have been fulfilled. Always wiling to take one for the team, I flew out to New York state to drive the 2016 F-Type S Coupe, fitted with the new manual transmission. (The trip included time in the F-Type R AWD that you'll hear more about later, and a long stint in the Range Rover Sport SVR, so I wasn't exactly shy about requesting the gig.) The short version is that the F and the 6MT get along like special sauce, lettuce, and cheese. But for the detailed blow-by-blow follow along. Driving Notes So, how is the manual? That's the primary force animating this review, after all. The short answers are: great, fine, just dandy. The middleweight clutch (not too light, not too firm) is easy to operate at speed or in heavy traffic. The gearlever offers positive, smooth action, not particularly mechanical, with throws that are of average length. The closest analogous experience I've had is with BMW manuals, though the Jag's clutch is slicker. But the biggest win for the stick shift in the F-Type is spiritual (if you'll excuse my being a bit romantic). This is after all the heir to the E-Type legend, a stirring rear-drive coupe (or convertible) that looks like wet sex and goes like heaving hell. The eight-speed automatic will continue to offer a more modern driving experience, but the manual just feels right with the car. You're going to have to prefer that kind of purity over outright speed to get the manual, too. Jag with sell you a hand-shaker with the base, 340-horsepower F-Type or the 380-horse F-Type S, but not with the V8 or new-for-'16 AWD variants. The supercharged V6 in the S is far from disappointing. Keep the sport exhaust active and you're likely to be the best sounding thing on the road that day, unless you run up on a coffee klatch of Ferraris.

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.
