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.

2014 Jaguar XFR-S super sedan is 550-HP worth of cool

The 2014 Jaguar XFR-S was considered last year, teased last week and now has been totally let loose. The most powerful sedan the company has ever made and the newest addition to its line of R-S performance cars - following the XKR-S - and we'll be getting even fewer of them than we thought. 200 had been the rumored allotment for the US, but the official word now is that we'll see just 100.
Each XFR-S will use the same 5.0-liter supercharged V8 that powers the XKR-S, meaning a 40-horsepower and 41-pound-foot bump over the XFR for 550 hp and 502 lb-ft in total. Shifting through the adaptive, eight-speed ZF transmission gets it from standstill to 60 mph in 4.4 seconds, but for all that, it gets the same gas mileage as the XFR, aided by its stop/start system, and so doesn't get hit with a gas guzzler tax.
Other XKR-S bits have made the jump, including an upgraded suspension front and rear, the near-straight pipes for the cracking exhaust note we drank up like ambrosia and twenty-inch, six-spoke lightweight wheels that are an inch wider than on the XFR. Lateral stiffness is up 30 percent, the electronic systems have been recalibrated to handle the extra oomph, throttle response has been sharpened and can be made even sharper by going into Dynamic Mode.

2014 Jaguar XKR-S GT takes fiercest feline further [UPDATE]

If there were any car to overshadow the 542-horsepower Jaguar XJR that's coming to the New York Auto Show, this is it. Meet the Jaguar XKR-S GT - a street-legal, higher-performance version of the already hardcore XKR-S that will be headed to North America in very limited quantities. Only 30 will be offered on our continent, with 25 earmarked for the United States and the remaining five going to Canada. The cost of entry? $174,000 when it goes on sale this August.
What that gets you is a coupe that is, without any doubt, ready to attack any racetrack it might encounter. The XKR-S' supercharged 5.0-liter V8 has not been upgraded in terms of power - not that 550 horsepower and 502 pound-feet of torque is anything to sneeze at - but instead, Jaguar focused on tuning the bits of the car that help effectively put all that grunt to the ground. There's a new hood with rows of louvers to aid in engine cooling, and elsewhere on the car's body, you'll find carbon fiber on the redesigned front air splitter, dive planes, extended wheel arch spats, as well as a new rear diffuser, an aluminum front under tray and an absolutely massive wing out back to keep downforce to a maximum.
Underneath that hot body are retuned and height-adjustable adaptive dampers; spring rates have been increased by 68 percent in front and 25 percent at the rear versus a standard XKR-S. Most of the front and rear suspension geometry has been upgraded, larger carbon ceramic brakes have been fitted at all four corners, and wider 20-inch forged alloy wheels are found here, wrapped in Pirelli Corsa tires - 255/35-series rubber in front and 305/30-series stuff out back. There's also a revised active exhaust system, which should only improve the already thunderous roar coming out the back of the Jag coupe, and a faster steering rack has been added for improved agility.
