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.

Jaguar teases four-door EV grand tourer; electric Range Rover orders open this year

Jaguar just revealed a few vital details about a new EV it says will be revealed by the end of 2023, and Land Rover shared a little update about its upcoming electric Range Rover, too. Starting with the Jag, JLR — the new, official name for Jaguar Land Rover — announced that its next electric vehicle will be a four-door GT car. The image above is the teaser the company provided. Power output will be greater than any previous Jaguar, with the current record holder being the XE SV Project 8 at just over 590 horsepower. Range is claimed to be about 430 miles on a full charge (Jaguar doesn't specify the test cycle type), but that number could be different (and likely lower) here in the United States once EPA testing takes place. Jaguar says the grand tourer will debut its new in-house EV platform that is officially named JEA, which is unrelated to the electric XJ that was scrapped a couple years ago. And lastly, Jaguar says the vehicle will start at GBP100,000 in Great Britain. Pricing for the United States wasnÂ’t estimated, but a direct conversion at todayÂ’s rates puts it at about $124,000. Considering the price point, power level and range, this Jaguar is shaping up to be a potential Porsche Taycan competitor. The single teaser image at the top of this post suggests the same, as the photo shows a car with a fast-sloping roofline and wide, bulging fenders. ItÂ’s an exciting teaser, as it pretty much confirms that Jaguar will be coming in hot with a spicy-looking electric four-door. The last detail about this Jag confirmed today is its production site, as Jaguar says it will build the vehicle at its Solihull plant in the West Midlands, England. As for the Range Rover news, weÂ’ve known an electric Range Rover was on its way, now we know that the vehicle will launch in 2025. JLR says it will begin accepting orders for the electric Range Rover later this year, but didnÂ’t set an official date. The electric Range Rover will be built at JLRÂ’s Halewood plant in Merseyside, England. Those are all the details we know about today, but expect more teasers and information leading up to the reveal of these new EVs later in 2023. Related video: This content is hosted by a third party.
