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 Land Rover recalls Takata airbag-equipped cars

In the latest chapter of what feels like the never-ending recall, Jaguar Land Rover announced that it's calling back 2009-2011 Jaguar XFs and 2007-2011 Land Rover Range Rovers for defective Takata airbags on the front passenger side. These Takata airbags have propellant that may have degraded and, if activated, could release metal shrapnel. The company is breaking up the recall into four phases, since currently there are not enough parts to do a full recall. Since the airbags can be more seriously affected by high heat and humidity, the first phase will cover vehicles that were sold and/or registered in regions with high temperatures and humidity. The regions included are as follows: Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands, and the US Virgin Islands. Other phases will begin as parts become available, and priority will be given to regions at greater risk of having defective equipment. Jaguar Land Rover encourages owners of affected vehicles to go to www.SaferCar.gov to check if their vehicle is included in the current recall. The first phase includes 54,000 of 108,000 affected vehicles. The company is also notifying owners of the issue, who will eventually get a second notification when parts are available so they can schedule a time to have the airbags replaced. Related Video:

2013 Jaguar XF Sportbrake

Editor's Note: Our reporter was anxious to get some time behind the wheel of the XF Sportbrake, even though Jaguar only had a very small window available for us to drive it. As a result, we weren't able to capture our usual original images to go with the Quick Spin story. Please accept our regrets, and Jag's lovely stock photography, instead.
The last wagon attempt from Jaguar was the X-Type, built between 2003 and that model line's unceremonious end in 2009. That X-Type and its legacy represent a real dog of a chapter for Jaguar, and for the Halewood factory where the barker was built. It was the final joke told prior to the brand's proper rebirth phase - a phase we're enjoying the heck out of today.
Current magnanimous Jaguar owner Tata can be thanked for this new wagon, the XF Sportbrake. Like all newness coming from Jag these days, this new wagon also feels lightyears more serious an offering, ready to compete squarely with established premium wagon makers across Europe. A Jaguar wagon in America is a far-off priority for the company, frankly. Still we deserve to know what we're missing for the time being from this (sometimes overly) cherished British firm.
