Jaguar releases C-X75 concept build story

If you want to know what was going through the minds of decisionmakers at Jaguar when the company decided to build the batty C-X75 Concept, look no further than the quick video after the jump. Jaguar set about building a car with the performance of a Bugatti Veyron, the electric range of a Chevrolet Volt and the emissions of a Toyota Prius, and they turned to a legendary engineering firm to help make it happen. Williams, the same crew behind Williams F1, helped Jaguar stitch the concept car together, and the result is unlike anything we've seen before.
The twin-charged 1.6-liter four-cylinder mounted amidship is paired with an electric motor at each wheel for a combined output of over 850 horsepower. And, since the whole chassis is hewn from carbon fiber, a production version would've been light enough to give machines like the McLaren P1 and Ferrari LaFerrari a run for their money. Shame they apparently couldn't make the business case work. Watch the concept build story in the video below for yourself.

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 XJ220 leaps into Jay Leno's Garage

Having sadly canceled the C-X75 project and sat out today's hybrid hypercar race, it would be all too easy to forget about Jaguar as a supercar manufacturer altogether. But back in the early '90s, the British automaker didn't just play in the supercar game – it dominated it. The XJ220 was, for a time, the fastest car in the world. Jay Leno pays tribute in this latest video. Originally envisioned with a V12 engine and all-wheel drive, the XJ220 ultimately surfaced with a 3.5-liter twin-turbo V6 driving the rear wheels alone. None of that kept it from eclipsing the top speed achieved by every supercar that came before with a terminal velocity that didn't quite reach the 220 miles per hour initially promised, but came pretty darn close. The disappointment in the change of specification lead some to dismiss the XJ220 as a failure, but it was still the fastest thing on the road until another British supercar (in the form of the McLaren F1) took its place at the pinnacle of automotive bragging rights. Two decades later, Jaguar quite nearly drove down the same road when its initial plans for the C-X75 changed from an experimental turbine powertrain to a multi-charged inline-four. Only this time the Leaping Cat marque didn't put it into production at all, save for a few prototypes and movie props – which is a bit of a shame, and then some. Watching Jay speed down memory lane in the supercar that almost never was, we're glad that Jaguar still built the XJ220, and saddened that it never followed up with another groundbreaking supercar today.
