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.

Has the Jaguar XKR-S Sportbrake leaked out early?

Want to haul ass down the Autobahn with the whole family and all their gear in tow? Forget that Porsche Cayenne or Jeep Grand Cherokee SRT8 - what you'll want is a power wagon: something like an Audi RS6 Avant or Mercedes-Benz E63 AMG Estate. Unfortunately there are precious few of these performance station wagons on the market anywhere, especially with American offerings like the Cadillac CTS-V Sport Wagon on its way out and the Dodge Magnum SRT8 long gone. But there's a new challenger emerging.
That'd be the Jaguar XFR-S Sportbrake, a hi-po estate from Coventry that's been a long time in the making. And now it's apparently almost here. (Only by "here," we mean "there," as it's not likely ever to come to the United States.)
Apparently set to be unveiled at the Geneva Motor Show is a Frankenstein-style cross between a Jaguar XF Sportbrake and XFR-S performance sedan, taking the best elements from both. From the former, that means the extended roofline that gives it the cargo capacity of a small crossover. From the former, that means a 5.0-liter supercharged V8 producing 542 horsepower and 502 pound-feet of torque, driving the rear wheels through an eight-speed automatic transmission.

Junkyard Gem: 2002 Jaguar XJR

One thing that's a constant in the big self-service car graveyards is the presence of massively depreciated European luxury sedans. These cars come from the factory stuffed full of complex leading-edge technology, and they require the owner to check every box on the maintenance schedule, year after year. Once that 10-year-old A8 or S-Class reaches its fourth owner, broken stuff often goes unrepaired, convenience-store generic oil goes in the engine (that is, if the engine even gets any new oil), and the European Luxury Sedan Doomsday Clock starts ticking. Here's a factory-hot-rod Jag that sold new for quite a bit more than a BMW 745i and just 20 bucks less than a Mercedes-Benz S430, back when Enron's machinations were in the news and a lot of energy-industry execs were about to get their luxury sedans repossessed, now in a Colorado self-serve yard. We live in a golden age of forced-induction engines in U-Wrench junkyards, with all sorts of turbocharged and supercharged machinery just waiting to provide the raw materials for a really stupid engine swap. The 4.0-liter, 370-horsepower V8 in the 2002 XJR would be just about perfect for installation into, say, a Datsun Maxima. This yard charges just $44.99 plus $10.60 in core charges and environmental fees for any supercharger, be it the dime-a-dozen Eaton M62 found on GM 3800s or the mighty M112 that was once buried between the heads on this engine. Thing is, you need to get to a car like this immediately after it hits the yard, because the first junkyard shopper with sufficient tools is going to grab that ultra-cool blower right away. The price tag for this car started at $71,830, which comes to about $105,550 in 2020 dollars. We can assume that some four-figure repair became necessary, and that this car's final owner had to let it go to the highest bidder with cash on hand… which turned out to be U-Pull-&-Pay. Look, you could still get a cassette player in a high-end luxury car in 2002! When do you suppose CD players will finally disappear from new cars? Here in the junkyard, the lowly Kia becomes equal to the majestic Jaguar. Perhaps their metals will be reused in a Geely next year. This content is hosted by a third party.
