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.

Top Gear has an Extra Gear problem | Episode Review

When the BBC announced Extra Gear, I was excited. As an avid fan of show's like The Talking Dead – companion show to AMC's hit The Walking Dead – a behind-the-scenes look at my favorite motoring show sounded promising. But with the fifth episodes of each show, I'm worried that Top Gear is suffering to keep Extra Gear interesting. We'll start with Chris Evans, inarguably the most heavily criticized member of the new Top Gear team. Evans is progressively less shouty and more comfortable filming while driving in each episode – the fifth is no different. He's almost likable in the Zenos E10 video, like a ginger James May, and he delivers accurate and eloquent driving impressions. The review is entertaining, until Extra Gear shows the producers cut a huge element – an old-versus-new sprint around the Race of Champions circuit at the Olympic Stadium in London. Former Formula 1 ace David Coulthard would drive a Caterham 360, while current F1 pro Daniel Riccardo rocked the Zenos. If the entire premise of Evans review is that the Zenos E10 is the newest of the new for British super-lightweight track toys, why did the producers decide to leave a race against the segment's standard bearer for Extra Gear? It's a baffling move, cutting a segment of the film that reinforces Evans' excitement over the Zenos. Rory Reid's Jaguar F-Type SVR piece is excellent. Fifty five years to the day after Jaguar test driver Norman Dewis raced to the Geneva Motor Show in a second E-Type for display, Reid would attempt the same feat in an SVR. If he failed, Jaguar wouldn't have a car to display. Dewis made the 750-mile trip with 13 hours of notice, and Reid would need to do the same. It's a brilliant, simple premise that reminded me of Jeremy Clarkson's so-called "Race against God" in a Jaguar XJ, way back in season 16. The history of the challenge and Dewis' gravelly commentary add gravitas. But the entire film goes by so fast. It's longer than Evans' Zenos video or Harris' BMW M2 film, but at less than ten minutes, Reid and the SVR deserved more screen time. Extra Gear poured salt in that particular wound with a great segment featuring Norman Dewis that deserved to be in the main show. Reid takes the famed test driver for a spin around the Dunsfold track, then, instead of the comedian of the week, the hosts interview Dewis on Extra Gear's couch.

On Location in Montenegro with Jaguar

I didn't know much about Montenegro until just a few weeks ago, when Jaguar invited Autoblog to the country to test out the 2017 F-Pace. In case you missed our write-up, the vehicle is excellent. So, it turns out, is Montenegro. According to the all-knowing Wikipedia, "It has a coast on the Adriatic Sea to the southwest and is bordered by Croatia to the west, Bosnia and Herzegovina to the northwest, Serbia to the northeast, and Albania to the southeast." That's a dry way of saying that Montenegro is situated in a beautiful part of Europe, with mountains galore, glorious coastlines, and spectacular rocky cliffs that plummet into the Adriatic Sea. Getting to Montenegro is a bit difficult. There are two airports in the country, neither of which is particularly large or easily accessible. Driving can be a challenge, too; since most of the country is mountainous, there are exactly zero highways within its boundaries. There are, however, lots of winding two-lane roads with picturesque views and a ferry system to shuttle vehicles across some of the larger bodies of water. Montenegro is a great place to experience a vehicle like the Jaguar F-Pace, which offers great driving dynamics across a wide variety of road surfaces. And as you'll see in the video above, surfaces vary widely in Montenegro. If you want learn more about the 2017 Jaguar F-Pace, stick around for the second video in the playlist.
