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.

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.

Jaguar Vision Gran Turismo SV ups the performance of the virtual sports car

Last year, Jaguar created its very first concept car made specifically for the Gran Turismo video game series, and this year it's following it up with an even faster racing variant. It's called the Jaguar Vision Gran Turismo SV, and it has some pretty wild specifications. This virtual racing machine no longer uses three motors, but four, with the extra motor being fitted to the front and allowing torque vectoring at all four wheels. Output has increased substantially to 1,877 horsepower and 2,478 pound-feet of torque. The regular Jaguar Vision Gran Turismo "only" made 1,005 horsepower and 885 pound-feet of torque. Jaguar claims a 0-60 mph time for the SV of 1.65 seconds and a top speed of 255 mph. That top speed might be higher if it weren't for the various aerodynamic aids adding downforce. It has a huge splitter, diffuser and long adaptive rear wing. The car can create up to 1,000 pounds of downforce at 200 mph. One other wild performance feature is the cooling system for the lithium-ion battery pack. It has a coolant circuit with liquid nitrogen that ensures the battery doesn't overheat when discharging the massive amount of electricity to run the powerful motors. Though Jaguar will likely never actually produce a functional version of this car in real life, the company did at least create a full-size model of it. It should be impressive in person given its extraordinarily low, wide and long shape. We're hoping it shows up at car shows when the pandemic subsides. The virtual car is due to be available in 2021. Jaguar didn't specifically say which version of Gran Turismo is will be featured in. The regular car can be driven in "Gran Turismo Sport." The racing version could be added to "Gran Turismo Sport," but the launch date of 2021 has us wondering if it will instead show up in "Gran Turismo 7" for PlayStation 5. Related Video:
