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 explains the perfect driver seating position

Although the shapes of car seats are one-size-fits-all, manufacturers have created numerous ways to customize how seats are positioned in efforts to cater to the multiple sizes of drivers. Whereas old vehicles only had the options of reclining and sliding forward or backward, new cars have seats that move up, down, forward, backward, and just about any other direction. In a new video, Jaguar demonstrates exactly how to use these features to find the perfect seating position. The advice comes from Steve Iley, Jaguar Land Rover's chief medical officer. Many people only think of seating position as a means to comfort, but when dealing with posture, it can affect a person's health. Iley's first tip is to empty out your pockets, thus avoiding any impingements. That includes anything from wallets to keys to cellphones to stowed-away snacks. Before putting a seatbelt on, the driver should then make sure his or her butt is all the way to the rear of the seat and that the entire back is touching the seat. Next are the seat adjustments. Iley suggests moving the back of the seat until the driver's spine and pelvis are aligned and straight. Note in this position the driver's thighs should be resting on the seats without any pressure points. Following this step, check the distance and position of the feet relative to the pedals. Jaguar says in the correct position, the leg should still be slightly bent when a pedal is fully pressed. The driver's elbows should be in a similar slightly bent position. With both hands on the wheel, make sure the arms aren't straight and have a slight kink at the elbow. In an ideal position, the driver's shoulders should remain in contact with the seat even during turning. Last, the headrest should be aligned with the top of the head. Not mentioned in Jaguar's advice is that NHTSA urges you to sit at least 10 inches from the steering wheel — as far back as you can while still comfortably reaching the pedals and wheel — in order to minimize the potential for serious injuries from airbag deployment, and the old 10-and-2 hand position is discouraged for the same reasons. Hands at 3 and 9 or at 4 and 8 are the new norm. AAA demonstrates in the video below. If any part of this doesn't make sense, you're in luck. Both videos are helpful.

The Jaguar XJR-15 is a 215 mph, barely-legal road car that's for sale

The late 1980s and early 1990s were awash with supercars from automakers across the globe. Classic Driver in the UK is selling one of the rarest of all of these supercars, the road-going racecar that is the Jaguar XJR-15. The XJR-15 is the lesser known sibling of the Jaguar XJ220. Only 27 were ever built. The XJ220 may not have received the same recognition and reverence as the Ferrari F40, the Porsche 959, and the McLaren F1, but for a time it held the record for the fastest road-going automobile, 217.1 mph. All of the XJ220's engineering and prowess is owed to the development of the XJR-15, which in turn owes everything to driver Tom Walkinshaw and his experience in touring and Le Mans racecars. Unlike the twin-turbocharged XJ220, the XJR-15 features a big, naturally-aspirated V12 that turned out 450 horsepower and 420 lb-ft of torque when new. The engine has a dry sump oil system, a Cosworth forged crankshaft, connecting rods, aluminum pistons, and fuel delivery from a Zytec electronically controlled sequential fuel injection system. The engine is mated to a five-speed transaxle from Tom Walkinshaw Racing, while the suspension - fabricated wishbones and horizontal pushrod-spring dampers at the front and coil springs at the rear - is pulled straight from the XJR-9 racecar. At the time, the car was capable of hitting 60 mph in under four seconds and topped out at 215 mph, just shy of the mark later set by the Jaguar XJ220. The XJR-15 was also the first road car to make extensive use of carbon fiber. In fact, at 2,315 lbs, the car's listed weight is less than that of a new ND Mazda Miata. The body was designed by future McLaren F1 engineer Peter Stevens. While the McLaren and Porsche were more complete and well rounded machines, the XJR-15 was a bare bones, uncompromised track machine. The interior was barely more than a carbon tub fitted with a pair of one-piece seats. The car in this listing is chassis number 21 and only has 1,400 miles on the odometer. Some minor modifications to the hinges allow the hood and engine cover to be quickly and easily opened. The car is listed for GBP450,000, or about $560,000.
