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.

Junkyard Gem: 1977 Jaguar XJ-S

The Jaguar XJ-S was big, powerful, swanky, and expensive, just the sort of luxury coupe a high-roller in the late 1970s craved. Unfortunately, these temperamental cars needed plenty of regular maintenance, and many of them suffered from neglect once they left the hands of their original owners. I see plenty of V12 Jaguars during my junkyard journeys, but it still gives me a twinge of sadness when I see another one parked among the ordinary Jettas and Grand Vitaras in the import-cars section of a big self-service wrecking yard. Here's a forlorn-looking, V8-swapped '77 in a San Francisco Bay Area yard. Chevrolet small-block V8 swaps were very common with the Jaguar XJs of the 1960s and 1970s, since an ordinary 350 would make power similar to that of the 326-cubic-inch V12 and parts obtainment was much easier. Still, swapping in a reliable-if-oil-leaky Detroit V8 didn't solve all the Jag's reliability woes: the Prince of Darkness retained a powerful grip on this car's soul. The patina on this car suggests decades spent forgotten in an outdoor storage area somewhere. There's a AAA map of California from the 1980s inside. This car listed for $20,250 when new. That's about $87,500 in inflation-adjusted 2018 dollars, but still $5,000 cheaper in 1977 dollars than a new Mercedes-Benz 450SLC (and a grand more expensive than a new Cadillac Fleetwood Brougham). Nobody in their right mind would have been willing to pay to restore this car, but we can hope that it provides some good parts to Jaguars that are still on the road.

Has the Jaguar XKR-S Sportbrake leaked out early?

Want to haul ass down the Autobahn with the whole family and all their gear in tow? Forget that Porsche Cayenne or Jeep Grand Cherokee SRT8 - what you'll want is a power wagon: something like an Audi RS6 Avant or Mercedes-Benz E63 AMG Estate. Unfortunately there are precious few of these performance station wagons on the market anywhere, especially with American offerings like the Cadillac CTS-V Sport Wagon on its way out and the Dodge Magnum SRT8 long gone. But there's a new challenger emerging.
That'd be the Jaguar XFR-S Sportbrake, a hi-po estate from Coventry that's been a long time in the making. And now it's apparently almost here. (Only by "here," we mean "there," as it's not likely ever to come to the United States.)
Apparently set to be unveiled at the Geneva Motor Show is a Frankenstein-style cross between a Jaguar XF Sportbrake and XFR-S performance sedan, taking the best elements from both. From the former, that means the extended roofline that gives it the cargo capacity of a small crossover. From the former, that means a 5.0-liter supercharged V8 producing 542 horsepower and 502 pound-feet of torque, driving the rear wheels through an eight-speed automatic transmission.
