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.

2017 Jaguar XE: We'll miss our long-termer, but not its diesel engine

This may be automotive journalist blasphemy, but diesels aren't always a good thing. And I don't mean that from an emissions standpoint. Sometimes the diesel in question isn't a good engine, and/or is a bad fit for the cars to which they're fitted. Our long-term Jaguar XE diesel is a textbook case of both issues. The first issue becomes apparent from the moment the 2.0-liter turbodiesel four-cylinder fires up with all the clattering, tapping and ticking that can only come from a compression-ignition engine. It's far from the shaking and knocking of full-size diesel trucks of a few decades ago, but it definitely feels a generation or two behind other diesel cars. For instance, we had a diesel Chevy Cruze in the office, which was quieter and smoother than the Jaguar despite a base price roughly $10,000 less. It becomes a bit smoother and less raucous as revs increase, but the volume remains rather high, making it sound as though the engine is struggling more than it is. Though, to Jaguar's credit, the company has managed to keep virtually all engine vibrations from entering the cabin. Now, the diesel engine's voice would be less problematic if it provided some engaging performance, but, outside of the high fuel-economy numbers, there's hardly any to be found. This may seem surprising considering the Jaguar's 318 pound-feet of torque, but that torque figure lasts only briefly from 1,750 rpm to 2,500 rpm. After that, the torque rapidly falls off, and you don't see the Jag's meager 180 horsepower peak until 4,000 rpm -- not far off of the engine's roughly 5,000-rpm redline. As a result, the XE has adequate passing power and around-town shunt, but anytime you want to play with more revs, it faceplants. But at least it does nail, and even exceed, its 40-mpg highway fuel economy rating without trying. The faults of this diesel engine are then exacerbated by the fact that it's in such a smooth and fun car as the XE. It positively glides across rough city streets and highways, keeping the chassis steady and its passengers soothed. Coupled with a quiet cabin, the XE is a peaceful place to be. At least it would be if the diesel didn't rudely interrupt every time the throttle pedal is pressed. Through some sort of black magic, the XE handles about as well as it rides. The incredibly sensitive and accurate steering is superb. It feels like adjustment knobs on a high-end stereo -- weighted perfectly and fine enough to get it right where you want it.

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:
