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.

Take a trip down Jaguar's memory lane with Xcar

For decades, Jaguar has been a company of two minds. On one hand, there are its luxurious, British saloon cars. They might be quick, even sporty, but when it comes down to it, they usually put a focus on comfort and accommodations above all. On the other hand, Jag has its sports cars to really get its buyers' blood pumping. Think about it: the XJ might look pretty sweet, but you know deep down that you would rather take the F-Type for a spirited drive, reveling in its snorty exhaust note. In its latest video, Xcar Films takes us on a very enjoyable history lesson covering some of the Brit brand's most exciting models ever.
Xcar hits all of the highlights, starting with the often-overlooked C-Type from early '50s with its somewhat bulbous shape. Things then progress to the drop-dead gorgeous D-Type. The one in this video is actually the first ever made and therefore worth a fortune. Because of that, the host isn't really able to get too aggressive, but it's fantastic to get an idea of what it's like to experience being behind the wheel of this icon. Finally, it ends with a Series 1 E-Type. This was when the classic model was still something of a sports car; instead of the grand tourer that the E-Type became in its later days.
All three of these cars are legends in their own right, and maybe one day the F-Type could be too. Scroll down for a history lesson on some of Jaguar's best sports cars.

Jaguar XJ electric sedan debut pushed to late 2021

Jaguar's been testing prototypes of the coming all-electric XJ sedan for a while now, an example we saw earlier this year testing in the cold having reached an advanced stage. The plan had been to launch the battery-powered flagship fastback this year, with sales to commence early 2021. A report in The Sunday Times says that plan has changed, Jaguar pushing the XJ back to the third quarter of next year while the automaker focuses on its finances and its most profitable models. The site FormaCar reports, "The presentation date on the official website now reads, 'October 2021,'" but we haven't found that XJ-specific page. In response to questions about the Jaguar canceling the XJ, a spokesperson responded, "Our engineers continue to work on the next-generation all-electric Jaguar XJ. We remain committed to our long-term strategy and our product portfolio remains the same, but the unprecedented situation will inevitably have an impact on our immediate plans." The Jaguar Land Rover group, coming off a string of deep losses during 2018 and 2019, was working through a cost-cutting and turnaround plan when Covid-19 hammered the global economy. The whispered concern among outsiders is that Jaguar will drop the XJ entirely, but that doesn't appear to be the case for now. The automaker cut thousand of jobs while investing more than a billion pounds into its Castle Bromwich factory to prepare for electric-car assembly. At the moment, Castle Bromwich normally builds the XE and XF sedans, those offerings also in flux while Jaguar reportedly considers turning one or both of them into a small hatchback or a compact plug-in hybrid sedan. We write "normally" because the factory was put on pause to deal with Covid lockdowns, and isn't scheduled to restart until August 14. And above all of this, JLR is on the hunt for a new CEO to replace Ralf Speth. We've been expecting the new sedan to open the book on mainstream luxury EVs, the same way the I-Pace did for SUVs, but it appears that won't happen. The electric XJ will come on the Modular Longitudinal Architecture, and we've understood the specs include a 90.2-kWh battery pack, the same size as the I-Pace pack. There have been rumors about a four-motor setup, but odds favor a twin-motor arrangement. The motors in the I-Pace produce 394 horsepower and 512 pound-feet of torque. For an XJ flagship, we'd expect an even more powerful option in the range.
