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.

Jaguar testing hardcore F-Type R-S GT?

Some automakers make a hardcore model, then sit back and revel in its awesomeness. Jaguar does things a little differently. It takes a standard production model, gives it more power, bigger brakes and a tighter suspension and slaps the letter R on it. Then it gives it even more power, even bigger brakes and an even tighter suspension and calls it an R-S. Sometimes the engineers in Coventry don't even think that's enough, so they strip out some weight and dial things up even further and call it an R-S GT.
So far, they've only gone that far with the XK (transformed first into the XKR, then the XKR-S, and finally the XKR-S GT), but with that model on its way out, Jaguar seems to be preparing to give the newer F-Type a similar treatment. Now we can't be sure that what we're looking at is an F-Type R-S GT, especially since the 550-horsepower engine from the XKR-S and XFR-S is already powering the existing F-Type R Coupe, but it does seem to have all the makings of a hardcore performance model.
Compared to the existing F-Type, the development model pictured here has a bigger front splitter (like the one on the Project 7 concept), a big rear wing and a set of what looks like pretty big lightweight alloys. It's also, tellingly, a roadster, which (unlike the coupe) has until now topped out at 500hp with the V8 S model. So while it may be hard to say exactly just what Jaguar has in store for us here (or what they'll call it), one thing's for sure: it's gonna be fast and loud.

2017 Jaguar XE First Drive

For the first time in decades, the prize for the best-driving compact luxury sport sedan is very much up for grabs. BMW's 3 Series, the segment's longstanding archetype, has grown a bit soft, distant and pricy. Its Japanese rival from Infiniti, the Q50, lost the plot thanks to its video game steering and dated powerplant. The Audi A4 is due for replacement and the fantastic Mercedes-Benz C-Class skews luxury over sport. The Cadillac ATS? With an excellent chassis hobbled by middling powertrains and the devil's own infotainment system, it isn't selling. Unlikely as it sounds, the Lexus IS is probably the segment's best driver, but you've got to learn to love those turn-to-stone looks. So, where's a segment malcontent to look? Provided he or she is patient enough to wait for this car's spring 2016 arrival, allow us to recommend the 2017 Jaguar XE. Let's be honest. Jaguar really needed to come out with guns blazing. The last time the British brand battled in the compact premium sport sedan segment, its much-maligned X-Type slinked into the underbrush, tail between its legs after just a single generation. While the X was in some ways a better car than history will begrudge it, there's no getting around that Jaguar brought a front-wheel-drive-based knife to a rear-wheel-drive gun fight. This new XE will need to be a very different kitty, and it is. Internally known as X760, Jag's latest rides atop an all-new aluminum-intensive modular architecture wearing a handsome mosaic of aluminum and steel body panels. While the XE's design has struck us as very familiar since it first bowed in September, it's an attractive shape. Its longish, 111.6-inch wheelbase and wheels-at-the-corner stance gives the design a planted look emphasized by its wide rectangular grille and prominent lower air intakes. Jaguar claims a super-slick .26 coefficient of drag, but that's the skinny-tired overseas base model that we'll never see – ours will likely ring up a few hundredths higher. The aluminum body-in-white is itself an impressive piece of work, weighing just over 550 pounds. Vehicle engineering manager Jonathan Darlington says it's 20-percent stiffer torsionally than the XF, and "the lightest in the sector by far." What's more, the chassis incorporates liberal amounts of recycled aluminum (a claimed world first) and increased use of structural adhesives.
