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 C-X17 resurfaces in China with gold finish, five-seat cabin [w/video]

Some concept cars make the rounds of the auto shows and are then retired. But a number of automakers are showing that a fresh coat of paint can go a long way towards rejuvenating a show car and giving it a new lease on life - at least as far as the auto show circuit is concerned. Lexus did that recently with the LF-LC concept, initially unveiling it in red at the 2012 Detroit Auto Show, then repainting it a dark shade of blue for the subsequent shows in Australia and LA. Mini did the same with the Rocketman concept. And now Jaguar has done it again with its C-X17.
Initially unveiled in electric blue at the Frankfurt Motor Show, Jaguar then rolled the crossover out again in liquid silver for the Dubai Motor Show earlier this month. Now the concept is back again at the Guangzhou Motor Show in China with a fresh coat of rose gold.
Looking decidedly more luxurious than the previous iterations, this gilded C-X17 concept also bears another change: while the previous versions featured a four-seat cabin, this one has been redone with a more conventional five-seat configuration that more buyers would likely go for. It's also got a new interactive infotainment system and another system that warns passengers of pedestrians or cyclists approaching from the rear before they open the door. Check it out in the high-res image gallery above and the video clip below for a closer look.

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.
