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.

2016 Jaguar XE pounces on the Parisian port

It's been about five years since Jaguar discontinued the misguided X-Type and exited the compact luxury sedan market, but today marks the British automaker's re-entry into the segment with the public debut of the all-new XE.
Pitted against the likes of the BMW 3 Series and Mercedes-Benz C-Class, the new Jaguar XE is based on an all-new aluminum architecture that will underpin many new felines to follow, and packs a new family of four-cylinder engines. That is, aside from the range-topping XE S pictured above, with the super-six borrowed from the F-Type.
Conservatively styled but elegant and uniquely Jaguar, the XE isn't set to arrive Stateside until 2016. So unless you're planning a trip overseas (with a stop at a Jaguar showroom on the itinerary), our gallery of live shots from the floor of the Paris Motor Show here at the Porte de Versailles may be the best look you'll be getting at Coventry's latest for the next couple of years.

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.
