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.

2020 Jaguar XE First Drive Review | The outlier's unusual charms

ST. TROPEZ, France — It's tough out there for compact sports sedans, even top contenders like the Audi A4, BMW 3 Series, and Mercedes-Benz C-Class. Jaguar resorted to a big-winged, bestial XE Project 8 that toppled a Nurburbring record to try and gain some attention, but the regular 2020 Jaguar XE will have to attain relevance on its unwinged charms against stiff German competition. We piloted the updated underdog through jagged hills above coastal France to see how its improvements stack up. For 2020, the XE receives a few subtle but effective styling tweaks — a resculpted front bumper, a wider and more purposeful grille, and a rear bumper with slimmer LED tail lamps that make the backend appear wider and more aggressive. Aerodynamic efficiency is slightly improved or equal to the previous model, depending on equipment. But the cabin receives more critical updates, specifically a much-needed upgrading of interior materials and trim. While higher-quality materials lend the XE a distinctly more luxurious feel, also welcome is a 12.3-inch driver display screen, Jag's familiar InControl Touch Pro Duo infotainment system (optional), and modern features like a wireless phone charging pad and a new steering wheel with updated illuminated controls. Small touches like wider, softer armrests, posher seat coverings, and more spacious door pockets also elevate the passenger experience — although the rear seats are tight at the knees and head for my 5'11" frame. Speed freaks and diesel fanatics will be disappointed to learn that the XE's engine options have, in Jaguar's words, been "rationalized" for 2020, dropping the 380-horsepower supercharged V6 and 180 hp four-cylinder turbodiesel. The only available engines for 2020 are both carryover units: the turbocharged 247 hp 2.0-liter four-cylinder (dubbed the S / P250), and the R-Dynamic S / P300, which is essentially the same mill with a bigger turbo producing 296 hp. Expect 0-60 mph times of 6.2 and 5.4 seconds, respectively. All-wheel drive is optional in the P250 model ($39,900 or $41,900 with AWD), and mandatory with the P300 ($46,295). Click the gear selector into Drive, and the cabin feels quiet and well insulated as the XE accelerates. There's a noticeable, but not enormous difference between the P250 and P300's acceleration.

Junkyard Gem: 1990 Jaguar XJ-S Convertible

The Jaguar XJ-S sold for big money, cost big money to keep running, and depreciated hard once its edges got a bit rough. You'll still find examples of the XJ-S in the big American self-service yards nowadays, but this '90 is the first convertible I have found in many years. 4,715 1990 XJ-Ss were sold in the United States; I haven't been able to find a reliable figure for the number of convertibles, but it must have been small. That makes today's Junkyard Gem a real rarity— not as hard to find as a Ford Tempo All-Wheel-Drive, of course, but still a prize. Jaguar kept the 5.3-liter V12 in production from 1971 through 1992, and when it was running properly — which wasn't as often as XJ-S owners wished— it couldn't be beaten for smoothness. By 1990, Jaguar had switched from fuel injection by The Prince of Darkness to a system made by Magneti Marelli. This one is quite rough, and it shows signs of having been parked outdoors with the top down for a few years. Since you can buy nice examples for well under ten grand, restoring this one would have been a money-losing proposition. This content is hosted by a third party.

In it, Bunny Lebowski reveals that none of her toes have been cut off by kidnappers; some suspension of disbelief is required here, because Americans couldn't buy the '90 XJ-S with a manual transmission. Maybe it's a gray-market six-cylinder car. The price tag on a new 1990 XJ-S convertible was a stunning $57,000, which comes to about $113,000 in inflation-adjusted 2018 dollars. Still, BMW shoppers had to pay $70,000 for a new 750iL that year, and that V12-powered machine didn't even have a convertible top. This content is hosted by a third party.
