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.

Weekly Recap: Things you might not know about the 2015 Dodge Charger and Challenger Hellcats

If you're an enthusiast, and you don't know that Dodge spawned another Hellcat this week, you really must have been living in cave. The 2015 Dodge Charger SRT Hellcat is probably the biggest news for enthusiasts since the reveal of, well the 2015 Dodge Challenger SRT Hellcat.
But, there are some things you might not know or might have missed about the new Charger and Challenger Hellcats. For starters, reports that the Hellcat production would be limited to a low volume are not true.
"We have not capped the Hellcat on either the Challenger or the Charger," Dodge CEO Tim Kuniskis said.

2020 Jaguar I-Pace Suspension Deep Dive | All kinds of weird and wonderful

I’ve driven the Jaguar I-Pace a handful of times, and it always proves to be an enjoyable experience. In case youÂ’re not up to speed, this is JaguarÂ’s dual-motor all-wheel drive all-electric SUV. ItÂ’s quick, it looks cool in a running shoe sort of way, and it delivers a decent 234 miles of range. Sure, it has its faults, particularly when it comes to the infotainment and climate control layout. But the electric JagÂ’s smooth ride comfort and direct steering feel are clear strong points, and its handling stays nicely balanced and displays sharp reflexes as far as IÂ’ve pushed it. That is to say, a strong pace, but nothing that would land me in jail. The suspension plays a big role in all of this, of course. I wanted to see what theyÂ’d done, so I recently put an I-Pace HSE up on jackstands and took a look underneath. Electric powertrain notwithstanding, I found this to be an utterly weird and fascinating machine.    From this vantage it is easy to see the big air spring (yellow arrow). The use of this type of spring medium allows the I-Pace to run at different heights. It mostly runs at standard height, but can also lower the car at highway speeds to lessen aerodynamic drag. ThereÂ’s an even lower mode to ease the loading of passengers and cargo, along with a raised-height off-road mode because, well, this is theoretically an SUV. It looks like it has a double wishbone front suspension, too, with a high-mount upper arm (green). But we canÂ’t be sure until we move in closer.   With the wheel turned, we can see that this is a double wishbone front suspension in the sense that it has a single ball joint (green) at the bottom. ThereÂ’s lots of nice-looking forged and hollow-cast aluminum bits and pieces, too. But it looks odd in some other respects. The lower arm (yellow), for example, seems to have a joint of some kind in it. Meanwhile, near the top, you can see how the tall upright (or hub carrier, if you like) is curved (red) to provide tire and wheel clearance. Use the wheel studs as a reference point and you can imagine how the tire assembly will nestle into that area.   The shock absorber (green) runs up the middle of what is a doughnut-shaped air chamber. A very tall tower of a doughnut, but you get the idea. But you canÂ’t call this a coil-over. Do I hear bag-over? Anyway, a position sensor (yellow) is connected to the upper arm so the height-control system can regulate itself properly.
