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: 1994 Jaguar XJ12

While Americans were able to buy new Jaguar two-doors with V12 engines under their bonnets from 1971 all the way through 1996, availability of new Jaguar 12-cylinder sedans was much spottier here. The Series 1 and Series 2 XJ12s were sold here from the 1973 through 1979 model years, and then there was a grim Jaguar V12 four-door drought here all the way until the 1994 model year. Here's one of those very rare felines, found in a Northern California boneyard in April. Jaguar had developed the XJ40 successor to the Series 3 XJ over an agonizingly protracted period that spanned the British Leyland era of the early 1970s through the first production cars being shown to the world in 1986. The XJ40 first appeared in the United States as a 1988 model. The following year, the Ford Motor Company bought Jaguar. The engineers in Coventry struggled to design a viable V12-engined XJ40 for years, giving it the XJ81 designation. At long last, the XJ81 was revealed to the motoring world in 1993… just prior to the replacement of the XJ40 by the XJ300 for the 1995 model year. All of the XJ81s sold in the United States—just over 1,500 of them in all—were 1994 models. This junkyard provided a bonanza of rare European iron when I stopped by on that chilly spring morning. Located within a few rows of this one-year-only XJ81 were a Volkswagen Phaeton and a Rolls-Royce Silver Shadow. The yard also had a running Peugeot 504 for sale in their "builders" section, and I'll admit I was very tempted by it. The April 1994 production date indicates that this is one of the very last members of the XJ40/XJ81 family to be built (though Jaguar continued to use platforms derived from the XJ40 until the X350a arrived as 2003 models). This 6.0-liter engine was an excruciatingly tight fit in this engine compartment (there are semi-credible tales that the XJ40's engine compartment was made so narrow as a sneaky office-politics means of preventing British Leyland from installing Rover V8s in Jaguars), and working on it must be a mechanic's nightmare. Output was 301 horsepower and 336 pound-feet. Meanwhile, Mercedes-Benz's V12 was rated at 389 horsepower and 420 pound-feet, while BMW's V12 had 296 horsepower and 332 pound-feet. The MSRP for this car was $73,200 for the dual-airbag version (and we can see that both airbags were deployed in this car's career-ending crash). That amounts to $151,889 in 2023 dollars.

Jaguar flagship J-Pace crossover due in 2021

We've been talking about a Jaguar J-Pace crossover for four years. In 2016, the large luxury SUV version of the XJ sedan was expected to arrive this year and challenge the Audi Q8, BMW X7, and Mercedes GLS. More recent information from Autocar put the J-Pace's length at roughly 4.9 meters (193 inches), putting the English offering in a bracket with the Mercedes-Benz GLE and the Porsche Cayenne. Dynamics will be the priority, with the J-Pace intended to "beat the Porsche Cayenne at its own game." The Jaguar will supposedly do this with a novel hybrid powertrain arrangement on the launch vehicle. The new Ingenium turbocharged inline-six, expected to be the "mainstream" engine, will turn the front wheels, the rear axle turned by an electric motor. That setup will provide more interior room thanks to the lack of a center tunnel, as well as finer control of torque to the rear wheels for better bad-weather and soft-roading character. Autocar said electric and four-cylinder versions were possible although not confirmed. The magazine said traditional gasoline and diesel versions without the electric motor out back would likely come only in two-wheel drive. However, not only is the phrase "front-wheel drive Jaguar" a terrifically un-sexy string of words, but the Modular Longitudinal Architecture (MLA) platform has supposedly been developed for rear-wheel- and all-wheel-drive cars. The Premium Transverse Architecture (PTA), an evolution of the aged D8 platform, supports the Range Rover Evoque, but all JLR products are planned to migrate to the MLA by 2025. The MLA will come in high-rise, mid-height, and low-rise versions. Products like the coming Range Rover and Defender will utilize the high-rise version. The J-Pace will use the mid-height MLA, along with the rumored Road Rover. The Jaguar F-Pace and Range Rover Velar take the low-rise PLA. These tiers would put a J-Pace roofline beneath the six-foot-two-inch-tall Range Rover and make for a sleeker appearance. Autocar also says that the J-Pace will have more luggage capacity than the Range Rover, quite the trick since the Jaguar won't be as tall and will be around six inches shorter. If it arrives in 2021, the shape could define the next stage in Jaguar design; the next-generation F-Pace has been predicted for 2022, so it could fall into line established by the big brother.
