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: Heated windshield option may drive you crazy

Our long-term Jaguar F-Pace is stuffed full of options. It's the top-trim S model with the most powerful engine, and we selected five of seven available option packages. The two we didn't pick were the cheapest ones. There were a handful of individual options we selected, as well, and one of them, the heated windshield, is one that you should definitely think twice about before choosing. The reason being that, in this editor's opinion, it's thoroughly irritating. I actually didn't even know our F-Pace had it the first time I signed it out for an evening. At the end of the day, I grabbed the key, walked down to the parking lot and drove it away without a second thought. A couple miles down Woodward Avenue, though, I noticed that my view out wasn't quite as clear as I expected. I figured the windshield was dusty or something, so on went the windshield washer for a few moments. After everything dried off, I had the same issue. I pulled the washer lever again and still nothing. I leaned forward and squinted my eyes, and that's when I spotted the minuscule heater wires across the entire pane of glass. And once I saw the wires, it was almost impossible to unsee them. My unobstructed view out the car suddenly turned into a CRT screen full of scan lines. They never kept me from safely driving the F-Pace (after all, they are extremely small), but I could never completely forget they were there. It's incredibly frustrating and it gets worse at night as the wires combine with oncoming headlights. I'm not the only one who dislikes them either, as Senior Editor John Snyder and Contributing Editor James Riswick voiced their displeasure with the feature. Not everyone in the office feels this way about the heated windshield, though. Associate Editor Reese Counts said that they don't bother him one bit. And in cold weather climates like Michigan, it should be handy for clearing snow, ice and condensation from the windshield. With these differing opinions, then, this is an option that you'll definitely want to experience for yourself before actually choosing it. You might find it unobtrusive or you might find it insufferable. As for me, I don't think I could deal with having those wires in my face all year 'round. I would rather spend 10 percent of the year when we have accumulating snow and ice scraping it off manually so that the other 90 percent of the year I have a crystal clear view of the road.

Artist imagines eerie world where cars have no wheels

The wheel ranks right up there with the telescope and four-slice toaster in the pantheon of inventions that have moved humankind forward. But what if a circle in three dimensions had never occurred to anyone, and we all had just moved on without it? Perhaps we'd be driving around in Lucas Motors Landspeeders with anti-gravity engines. Or maybe we'd have the same cars we do today, just without wheels.
That's the thought experiment that seems to have led French photographer Renaud Marion to create his six-image series called Air Drive. The shots depict cars throughout many eras of motoring that look normal except for one thing: they have no wheels. The models used include a Jaguar XK120, Cadillac DeVille (shown above), Chevrolet El Camino and Camaro, and Mercedes-Benz SL and 300 roadsters.
Perhaps one day when our future becomes our past, you'll be able to walk the street and see with your own eyes the rust and patina of age on our nation's fleet of floating cars. Until then, Monsieur Marion's photographs will have to do.
