542-HP Jaguar XJR to debut at New York Auto Show

Jaguar has just announced that a higher-than-ever performance version of its XJ flagship will be coming to this year's New York Auto Show next week. Joining the company's R lineup is this XJR, which will boast a stonking 542 horsepower from its supercharged 5.0-liter V8 engine.
Though details about the new XJ are pretty slim - you can read Jag's teaser of a press release - we are told that the car will ride on a "bespoke chassis" and that some aerodynamics work has been done, as well. The one sultry image we have of the car shows a set of trim-specific wheels, lower sills and unique badging on the front grille.
The new XJR would seem to slot above the current top-dog XJ, the XJ Supersport. With a bump up of 32 hp versus the Supersport, performance should get a meaningful shot in the arm, as well. As for pricing, we'll have to wait for the NYC show to be sure. But other Jaguar models show an increase of between 15- and 20-percent between the R model and the next one down; that would indicate a price tag in the $130k range for a standard wheelbase XJR is in order.

Jaguar to offer high-performance SVR models like Land Rover?

At the Goodwood Festival of Speed this past weekend, Land Rover previewed its upcoming performance version of the Range Rover Sport. Only instead of wearing the R-S badge that adorns the most hardcore of Jaguar models, the performance SUV from JLR's Special Operations unit introduced the letters SVR. And now, it seems that badge is here to stay.
Following the Range Rover Sport SVR, a new report from Motor Authority now says that Jaguar Land Rover will use those letters to distinguish the top-of-the-line performance models from both marques moving forward. As such, we might expect SVR models of the upcoming Jaguar XE compact sedan and Land Rover Discovery Sport, as well as potential new performance models based on the new F-Type and next-generation XF.
If accurate, the move would seem to separate Jaguar in particular from the R-S badge that has adorned performance models like the XFR-S and XKR-S. Both Audi and Porsche use the letters RS to distinguish its most hardcore models as well (e.g. Audi RS7 Sportback and Porsche 911 GT3 RS). Whether the similarity was a factor in shifting to the SVR moniker, we don't know, but either way, we welcome the arrival of a new generation of Jaguar and Land Rover performance models - especially if they pack the 575-horsepower version of the company's ubiquitous 5.0-liter supercharged V8. Not incidentally, that delicious powerplant gained a couple of new engine bays to call home at Goodwood as well - it's not just found in the forthcoming Range Rover Sport SVR, it's found a home in the F-Type Project 7, too.

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.
