Jaguar F-Pace V6 reminds us why we love supercharged engines

There are many things we like about our 2018 Jaguar F-Pace long-term car, as well as some things we don't care for, but easily one of the best things about it is the engine. Under the hood is the 380-horsepower supercharged V6 that Jaguar offers on other models. That amount of power would be fun in just about any car with any engine, but there are specific reasons why this particular engine is special, and it's because of that supercharger. Supercharged engines have a very different character than increasingly common turbo engines. One of the most noticeable differences being engine response. Unlike turbo engines, the F-Pace's V6 feels hardwired to your foot. Every extra millimeter of pedal travel yields a slightly greater amount of tug. And the tug is felt immediately. Even the best turbo engines have a hard time recreating this response. The power band is very linear, as well, so you know exactly what you're getting every time you hit the gas. The engine is wonderfully torquey, too. Because the Jaguar's engine uses a classic Roots-type blower, there's a major improvement in low-end torque. This means that our F-Pace has loads of grunt for punting around at low-rpm and can seriously move when tromping on the gas. And because of the near-instant throttle response and linear power band, it doesn't slam you in the back unexpectedly like some turbo engines do. Despite how great these supercharged engines are to experience, we're concerned that supercharged engines like this may disappear in all but ultra-limited production, high-performance cars such as the Chevy Corvette Z06 and Cadillac CTS-V. The reason being that car companies have to keep making cars more fuel efficient and lower emitting. Putting a supercharger on an engine is adding a handicap, since it takes engine power to spin the belt-driven supercharger. And when a turbo, which uses wasted energy from exhaust gas to spin the compressor and built boost, can effectively do the same thing, it's hard to make a case for a supercharger. We won't give up hope completely, though. Mazda is using superchargers on its spark-assisted compression ignition gasoline engines. And while we're not sure how powerful and sporty those will be, Mazda has said that it's going with superchargers for exactly the reasons we like the Jaguar engine: smooth power and fast throttle response.

2018 Jaguar XJR575 First Drive Review | Everyone loves an underdog, right?

The number is right there, nestled smack in the middle against the windshield in red: 575. In case you missed it, there are another four red 575s stitched into the seat backs. You might excuse Jaguar for the numerical ostentation, but with manufacturers taking the horsepower arms race nuclear, the 6-year-old XJR sure could use a hook. What better way to stand out than an engine output humblebrag? The $122,400 Jaguar XJR575 gains 25 horsepower for 2018 thanks to software recalibration, which helps scoot the 17-foot-long four-door to 60 mph in a claimed 4.2 seconds. I'm gunning the XJR575 along the mountainous passes near the Alvao Natural Park in northern Portugal to find out whether the upgrade is enough to keep this underdog relevant in the fevered pitch of the high-dollar sedan market. Glance at the Jag in profile, and you might doubt its athleticism. Though nearly identical in length to a long-wheelbase BMW 7-Series and Mercedes-Benz S-Class (and 1.8 inches shorter than the Audi A8L), the XJR575's sloping rear window and rounder styling lend it a somewhat lazier, more lavish appearance. It's also long in the tooth, this design having been first introduced in 2009, but it wears its age surprisingly well. Frankly, you just don't see XJ-series Jags as often as their strong-selling competitors, and that keeps them looking fresher, somehow. In contrast, the Germans have kept their exterior lines purposeful and contemporary looking, with more frequent redesigns furthering their cause. Climb inside, and the XJR's premium trim lends a bit more modernity to the familiar cabin. For starters, the diamond-quilted and perforated leather seats offer solid support, but they might be a bit firm for long hauls. Unlike other XJs, the XJR and R-Sport trims don't offer a massaging feature, an unfortunate sacrifice that is available on most, if not all, of the competitive set. The rear quarters do, however, offer enough legroom for serious stretching out. Tall swaths of carbon fiber trim the door panels while another thin rim of carbon extends around the dashboard, a design shorthand for sportiness despite the fact that the XJR is only available stateside in long-wheelbase form. An Alcantara headliner aids the high-end argument. A few aging elements show cracks in the facade, among them the ungainly seams at the dashboard's center and switchgear that's grown more than a bit long in the tooth.

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.
