Is the Jaguar XFR-S really worth $17k more than the XFR? [w/poll]

Adding performance to a car is rarely cheap - whether you're looking to do it yourself or rely on the factory to do it for you. In the case of the new Jaguar XFR-S, the cost differential over an already-impressive (and somewhat expensive) XFR is a stout $16,800. Auto Express recently got a hold of both cars to see whether that price pays off on the track.
For that price, Jaguar gives the XFR-S an extra 40 horsepower and 41 pound-feet of torque - for a total of 550 hp and 502 lb-ft - to go with a stiffer suspension, beefed-up differential and, of course, meaner styling. We don't want to ruin the results of the AE video, but right off the bat, the host says that you can feel the extra power of the XFR-S, but that it's not a "night-and-day difference."
Scroll down to see what happens when two high-powered Jags go head-to-head on a track. And then be sure to let us know whether or not you think the added money is worth it for the XFR-S in the completely informal poll below.

Junkyard Gem: 1973 Jaguar XJ6

It requires a certain high level of commitment to keep an old Jaguar on the road, and so plenty of first-generation Jaguar XJs end up as projects that never get finished, sitting in yards or garages for decades before winding up in the nearest U-Wrench yard. As I clomp through car graveyards around the country in search of interesting machinery, I see so many 1980s XJs that I don't bother to photograph many of them … but a genuine Series I early Jag is a different story. Here's a '73 XJ6 whose final parking space (prior to facing the cold steel jaws of The Crusher) sits right next to that of a same-year Mercedes-Benz 450SLC in an East Bay yard. How the mighty have fallen! The C107 was too picked-over to be worth photographing, but you can admire the photos of this much nicer '72 I found in Denver a few years back. Unlike the last Series 1 XJ6 that I've photographed (in the very same yard, albeit 13 years ago), this car has not had its original straight-six engine replaced by a small-block Chevrolet V8 (because Jaguar parts were expensive and Chevy parts were cheap during the 1970s, that swap happened frequently). The US-market XJ6 got 150 horsepower from this smooth-running DOHC six, 40 fewer horses than the (far more expensive) 450SLC that year. The interior looks ravaged by the decades, but you can still discern the opulence that once reigned in this wood-and-leather-lined space. The dash boasts a full complement of authentic Smiths gauges, with a tasteful Kienzle clock right in the middle. Here's why we can assume that fewer than two of those instruments functioned at any given time during the life of this car: wiring by The Prince of Darkness! Working on electrical faults in these cars built up your patience while undermining your faith in symptom-to-problem relationships. The six-digit odometer ensures that we'll never know if we're looking at a 56,819-mile car or a 356,819-mile car. I'd guess 156,819 if I had to, based on pedal wear. These cars were very popular in the Bay Area, which has been full of European-car aficionados since the first Renault AXs sputtered off the docks of the San Francisco waterfront. Back in the 1970s and 1980s, you'd never see an old XJ without one of these pre-EU "GB" stickers on the back. The faded condition of this one suggests decades of sitting in the sun, probably while the car sat dead in the driveway due to electrical problems.

Jaguar XJ220 owners will finally be able to get new tires

Bridgestone announced today that the underserved Jaguar XJ220 used-car market would finally have access to new tires. Apparently a number of years ago, companies stopped supplying road tires for the XJ220 altogether. Don Law, owner and operator of XJ220 parts and restoration company Don Law Racing, brought the issue to the attention of Bridgestone. Now, Bridgestone and Don Law have assembled a team that includes the vehicle's original chief development engineer and test driver to create a modern tire for the 213-mph supercar. Bridgestone was also able to get access to pre-production car 004 for testing purposes. The company plans to have the new tire ready for the car's twenty-fifth anniversary next year. From the sound of it, the tire will likely outperform the original one, as Bridgestone's vice president of consumer OE tires cited the advancement of tire technology over the years when talking about the project. This whole project also raises an interesting question. Are there any other supercars that don't have original equipment tire options anymore? The XJ220 certainly wasn't the only supercar of the '90s with fat tires on relatively small-diameter wheels. Also, what will happen to the tire market for modern supercars? The Bugatti Veyron famously has special tires designed to handle its extremely high top speed. It certainly is an interesting first-world conundrum, and one we're going to keep tabs on. Related Video:
