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 Heritage Driving Experience throws you the keys to the museum

As automotive journalists, we get to drive a lot of really cool, high-performance vehicles. It really is the single best thing about this job. However, our access to vehicles is generally limited to the newest offerings on the market. That means, much like the general public, we don't really get access to vintage iron.
Jaguar is trying to rectify that issue for journalist and enthusiast alike, with a new program called the Heritage Driving Experience. It allows British enthusiasts to pop into the brand's Warwickshire testing site, drop anywhere from 100 to 300 pounds ($160 to $480) and go for a spin in some of the brand's most legendary offerings. That includes the more typical classics, like the Mark 2 saloon and the E-Type sports car, but you can also pay for access to stunners like the XK150, XKSS and the race-spec D-Type. In addition to the classics, most of the tests include time in their modern successors. So an hour with the Mark II can be split with time in an XFR-S, while the E-Type is complemented by its spiritual successor, the F-Type.
Most of the events are limited to 30 or 60-minute sessions, although the brand does offer a half-day and full-day event. The former, the Jaguar Le Mans Experience, includes time in the C-Type, D-Type, XKSS and F-Type R. The full-day Grace and Pace Pack, meanwhile, gives you access to nine vehicles, covering a huge gamut. That means time in the C-, D- and E-Type, XK150, Mark II, XKR-S GT and F-Type R, among others. Not surprisingly, prices aren't listed for the half- and full-day pack. Much like Jag's finest cars, if you have to ask, you probably can't afford them.
