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 F-Pace SUV teased on YouTube [UPDATE]

UPDATE: Stuart Schorr, Jaguar Land Rover North America's VP of communications, reached out and explained that the Detroit section of the F-Pace video was recycled from the car's confirmation announcement at the 2015 North American International Auto Show, shown here. "There is 100 percent no subliminal message and Frankfurt is the debut location," Schorr told Autoblog. The story has been edited to reflect this information. With the Jaguar F-Pace slated to debut in less than 90 days, at the 2015 Frankfurt Motor Show, the teasers are starting to ramp up. That means videos like this, featuring Jaguar design master Ian Callum, which give us short, sweet peeks at the British brand's very first crossover. The big teasers come in the form of Callum's drawings of the F-Pace, combined with short clips of its headlights and taillights as it zooms around the streets of downtown Detroit. That said, none of the images shown are so dramatically different from the C-X17 Concept, the vehicle that previewed the production model and makes an appearance here. We aren't really sure why the Motor City features in the teaser, considering the F-Pace is being unveiled in Germany, but one of the final sequences sees a set of taillights streak past Cobo Center, home of the annual Detroit Auto Show. It's a weird decision to be sure, and leaves us wondering just how much truth there is to reports of the Frankfurt debut. Why would Jag make such a decision if the D weren't going to play some role in the car's future? Take a look at the video up top, and let us know what you think of Jag's first F-Pace teaser. Is there any particular design detail we missed? What do you think of the potential Detroit connection? Head into Comments and let us know.

Ex-Jaguar design boss Ian Callum starts his own design firm

A month ago, Ian Callum stepped down from his position as Jaguar's director of design. In a 20-year career with the English sports car maker, Callum's pen has traced the lines of everything from the original XK, the XJ, the F-Type, I-Pace, and more. Before that, he made use of employ at Aston Martin by contributing to the original DB7, the DB9, the previous Vantage, and the first Vanquish. After a career in service to OEMs that's been brilliant enough to earn him a CBE, for Commander of the Most Excellent Order of the British Empire, Callum has stepped up to take the reins at his eponymous design firm, called "Callum." Established with four fellow ex-Jaguar executives, Callum will design and engineer bespoke and limited-edition creations in the worlds of art, audio, automotive, fashion, lifestyle, and motorsports. The other trio of founding members are program director David Fairborn, engineering director Adam Donfrancesco, and commercial director Tom Bird. Fairbarn was the head of bespoke and special commissions at Jaguar Land Rover, where he helped bring the Lightweight E-Type to life. Donfrancesco left his role as engineering manager for JLR 's bespoke and special commissions; before that, he developed road and race cars like the Aston Martin GT8 and GT12. Bird, after stints at PWC and Barclays, had been commercial manager at JLR, where he shepherded the C-X75 concept into the James Bond movie Spectre. Callum said of the venture, "I wanted to get back to the essence of creativity; the challenge of producing something wonderful and personal. To design the alternative has always been my mantra, but always the beautiful alternative and something to enjoy." The man's still contracted to Jaguar as a brand ambassador, but at 64 years old, he feels "I've got maybe 15 years of design aptitude left, and I want to make the most of it." With 18 employees and based in a 20,000-square-foot facility in Warwick, the firm is ready right now with the engineering and manufacturing machinery to create products in-house. Even with the company's wide remit, we expect to see Callum take a stand in the automotive space. He admitted that he'd "like to take some of the cars I've designed and maybe redo them a little bit," but the team will always consider the entire vehicle, looking to upgrade dynamics and handling, too. We're told the first project will be announced soon.
