Jaguar takes evolutionary approach for 2016 XF [w/videos]

One week ahead of its debut at the 2015 New York Auto Show, Jaguar has let loose a slew of images and details on the second-generation 2016 XF Sedan. The release comes alongside a high-profile stunt over London's Canary Wharf. A total of 75 percent of the XF's body is made from aluminum, which trims the big cat's curb weight by 132 pounds on the rear-drive model and 265 pounds on the all-wheel-drive variant. Aside from aiding acceleration, braking and fuel economy, the advanced structure promises an increase in torsional stiffness as well as a 50-50 weight distribution. Beyond that, the new car's dimensions differ only slightly compared to last year's XF. The wheelbase has been stretched by two inches, although the new model is 0.3-inches shorter and 0.1 inches lower. Double wishbones are used in front while an integral-link suspension sits in back with standard traditional dampers and optional adaptive dampers. Jaguar is also promising the Configurable Dynamics system that was pioneered on the F-Type. No surprise here, but an electric power-assisted tiller will be in use, although Jag says it benefits from lessons learned with the XE. Jaguar is mum on its full powertrain lineup, although it does mention that both 340-horsepower and 380-hp versions of Jaguar Land Rover's familiar 3.0-liter, supercharged V6 will be offered, paired with standard eight-speed automatic transmissions (likely the highly regarded ZF autobox). Jaguar's designers, led by design director Ian Callum, didn't rock the boat too much for the new sedan. Clearly inspired by the upcoming XE, the new XF gets a wider, but thinner grille. The headlights are slimmer, but retain a similar shape compared to last year's car, and as is the trend, they're now lined with LED accenting. The S trim, shown above, gets wide, menacing grilles in the front bumper as well as a total lack of chrome trim. The XE influence is most evident on the XF's tail, where the Aston Martin-aping taillights of the first-gen have been ditched, with broader, angled units, complete with an F-Type-inspired LED pattern. As with the current car, a thin chrome strip ties the lights together, while the lower bumper on this sportier model features a gloss black surround for the dual exhausts. Not surprisingly, the XF's profile is pretty classic, with a very long hood and a short deck that terminates in a handsome duckbill spoiler.

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.

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.
