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.

2018 Jaguar F-Pace S is a fun but thirsty travel companion

I love road trips. I've moved across the country twice, spending weeks living out of my car, eating granola bars and sucking down energy drinks like it was finals week all over again. I get a huge kick out of calculating fuel economy, stretching out tanks of gas or diesel until the low-fuel light begins to sear itself into my retinas. I try to take each and every one of our long-term vehicles on some such trip. Not long after our 2017 Jaguar F-Pace S arrives, my wife and I decided to see some family in Asheville, North Carolina, roughly 10 hours and 700 miles from our home in suburban Detroit. Now, I knew from the outset this was going to be a far different experience than our previous long-termer, a 2017 Jaguar XE diesel. I managed to eek out nearly 700 miles per tank, averaging 42 mpg over 2,000 miles with that car. But the 380-horsepower supercharged V6 in the F-Pace is rated at 18 city/23 highway with a combined rating of just 20 mpg. Not good, and — unlike the XE — I didn't think I could do much better without greatly altering my admittedly aggressive driving habits. Still, I wanted to take our blue bomber to the Blue Ridge Parkway, so onward I went. There were a few other things I was worried about over what was sure to be another 2,000-mile trip. The F-Pace's suspension was a bit stiff thanks to the sporty S trim. The 20-inch wheels don't help matters, though things could be worse (some people on staff wanted to get 22s). At least they look good. Still, the seats are comfortable and the radio is top-notch. LCD Soundsystem's latest album had just come out, so I put it on repeat and headed south. The first part of the trip was going to be both the most boring and the most economical. The roads in Michigan and Ohio are flat and straight. It isn't until you hit Kentucky and head into the Appalachian Mountains that things get interesting. Just set the radar cruise control and barrel down Interstate 75 with as much urgency as you dare. I forgot my Valentine One at home. The ride was firm but not as bad as I imagined it might be, at least once we got off of Michigan's pockmarked pavement. The F-Pace tracked straight and true, but I became acutely aware that the steering wheel itself was out of alignment, leaning just slightly to the left. Fuel economy was fine, but I was just meeting the EPA estimate, not beating it like I usually manage to do.

Who picks car colors and materials? Designers like Hannah Custance

As automotive journalists, we're often asked "how did you get that job?" People usually didn't even know you could do such a thing. In this 7 Questions series, we're highlighting other jobs in the automotive industry that you might not have heard about before. What do they do, how'd they get to do it and other questions about their particular corner of the car world. Slowly but surely, the automotive landscape is becoming more colorful. Look beyond the unrelentingly conservative palette of white, black and gray most buyers opt for and you'll see the increased use of exterior trim types beyond the usual chrome. There's gloss black, of course, but also other metallic finishes like gold or copper. Those can be found inside, too, where there's also an increase in colorful leathers and trims, innovative fabrics, new wood types and finishes, and greater creativity in general. So where is this change coming from? The answer is designers like Hannah Custance, the color and materials design manager for Jaguar Land Rover. Her team's latest effort is also its magnum opus, the 2022 Range Rover. Although saddled with the expectations that comes with one of the automotive industry's classic nameplates, the all-new Range Rover is also a celebration of cutting edge manufacturing and fashion-forward materials selection. We sat down with Hannah at the L.A. Auto Show to find out more about color and materials designers, how she ended up in the industry, and advice she might have for young designers out there. It has been condensed for brevity. Autoblog: What does a color and materials design manager to do?Hannah Custance: I basically look after a team of designers who design finishes for every A surface on the car. So, that could be exterior finishes. It could be interior trim materials, soft materials, hard materials, chromes, metals, woods, ceramic – that's one of the new ones – anything you can kind of touch and see is color material design. Autoblog: How early in the design process does your team become involved.Hannah: Right at the very start. In fact, we look at materials that don't have a product assigned to them or a car assigned to them. So, it takes actually a very long time for us to get materials approved and fully validated. We have to find suppliers that are willing to work in automotive and our test standards are incredibly high, some of the highest in the industry.
