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's latest beast is the 2018 XJR575

Hot off the rear wheels of the insanely quick XE SV Project 8, Jaguar is back with another pumped-up sedan. It's called the XJR575, and although it isn't as extreme as the aforementioned XE, it still packs a version of the company's 5.0-liter supercharged V8 that makes 575 horsepower and 517 pound-feet of torque. According to Jaguar, that will get the full-size luxury sedan to 60 mph in 4.2 seconds on its way to a top speed of 186 mph. There isn't much on the outside to tell this hot-rodded kitty from the regular XJR. The front bumper, rear spoiler, hood vents, and side skirts are all the same as the lower-powered version. It does come standard with black wheels, but they can also be optioned on a normal XJR. There are only a couple of unique points. One of which is the addition of XJR575 badges. The other is the application of a model-specific paint color. Buyers of the XJR575 will have the option to coat their cats in the Satin Corris Gray seen above, or a hue called Velocity Blue. Inside, seats are upholstered in black leather with red stitching. They feature diamond-stitched panels, as well. In the seat backs, the number 575 is embroidered. The sill plates also feature the XJR575 logo. The infotainment gets an upgrade, too, in the form of a bigger 10-inch touchscreen. Jaguar hasn't announced pricing or availability of the XJR575 yet. However, we will likely know soon, as the company will be revealing some updates for the rest of the XJ line-up for the 2018 model year. We expect to get details on pricing and availability at that time. Related Video:

550-hp Jaguar F-Pace SVR revealed ahead of New York Auto Show

"I love this car." So said Jaguar designer Ian Callum, quite genuinely, as the Jaguar F-Pace SVR drove onto the stage at the company's new headquarters in Mahwah, N.J. Despite accepting and even embracing Jaguar's decision to produce SUVs, it's quite obvious (because he says so repeatedly) that Callum is still a guy with a lust for high-powered sports cars. The F-Pace SVR melds these two elements to create something he gleefully describes as "ridiculous." Boasting Jaguar Land Rover's now-familiar supercharged 5.0-liter V8, the SVR produces 550 horsepower and 502 pound-feet of torque. Jag estimates it'll hit 60 mph in 4.1 seconds and a top speed of 176 mph, which will make it one of the quickest and fastest SUVs on the road when it arrives in dealerships this summer. View 15 Photos It's not just the big engine, however. Upgraded mechanical improvements and enhancements include stiffer springs, wider and lighter forged alloy wheels (21- or 22 inches), bigger brakes (15.5-inch front, 15.6-inch rear), an electronic active rear differential, a variable active exhaust that's 14.5 pounds lighter than the standard one, and specially tuned software for the adaptive suspension, electric steering, eight-speed automatic, all-wheel drive and Dynamic Driving Mode. Callum's team also massaged the aerodynamics with larger air intakes, rear bumper side strakes, and fender vents that lower pressure in the wheel arches to reduce lift and increase cooling. A unique hood features vents designed to, well, vent hot air from the engine compartment. There are also wheel arch extensions and lower body moldings to create a more muscular appearance, while the rear sees fat quad tailpipes that one would assume should bark and burp like any good Jaguar SVR. Inside, there are thinner, light-weight sport seats done up in snazzy quilted leather. The rear seat also gets sportier seats with a similar fixed headrest design as those up front. The pistol-like sport gear selector shifter, as used in the Jaguar F-Type, replaces the standard rotary shifter design. It still takes up way too much room on the center console. Pricing starts at $80,985. One would assume Mr. Callum will gets his for less than that. Related Video:
