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.

40+ cars that barely avoid the gas guzzler tax

The Gas Guzzler schedule, with mpg ratings and charges that haven't changed since 1991, lays out which fuel-swillers owe what to Uncle Sam.
I started thinking about the "Gas Guzzler Tax" - considerably less well known as The Energy Tax Act of 1978 - when I was driving Dodge's new Challenger SRT Hellcat last week. Unsurprisingly for a car that can burn 1.5 gallons of gas per minute at max tilt, theoretically able to empty a full tank of premium in about 13 minutes, the Hellcat will be subject to the Gas Guzzler Tax schedule when it goes on sale.

Xcar focuses on famed Jaguar test driver Norman Dewis

If you have any interest at all in motoring history, especially when it comes to European sports car racing from the '50s and '60s, do absolutely whatever you can to set aside 38 minutes for this interview with former Jaguar test driver Norman Dewis from XCar. Dewis had a hand in developing the British brand's vehicles from 1952 to 1985, and as expected over that time, he amassed some fantastic stories. Xcar did a great job of teasing a few of those great tales out of him here. From the very beginning, Dewis was gifted with a natural talent to read a car as a test driver. When he was just 16, he was taken out on his first chance to evaluate a vehicle and picked out even more intricacies than his instructor. Dewis eventually wound up at Jaguar, and that's where his career really took off. Among his many accomplishments there, he had a role in developing disc brakes both for racing and the road, set multiple world top speed records, and helped bring the E-Type to the world. Dewis even made the famous overnight drive in an XKE convertible from England to display it at the Geneva Motor Show. Dewis tells a first-hand account of being in the Jaguar paddock during the tragic accident during the 1955 24 Hours of Le Mans that took the lives of dozens of spectators. It's a story that we usually can only read about or watch in black-and-white films. Hearing Dewis' side really brings this history to life.
