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.

Lister introduces 666 hp, 208 mph limited edition Thunder

Lister is one of the most storied nameplates when it comes to Jaguar-based racing cars, with tons of Le Mans heritage on its shoulders. The company says it's Britain's oldest surviving racing car company. As well as racing cars, Lister has produced several road-going specials, such as the widened XJ-S derivative called Le Mans and the Storm, whose 7-liter V12-engine was not only based on the XJR-9 racing car, but also the biggest V12 engine fitted to a production car since WWII. Now, in addition to continuation specials like the reborn Knobbly, there is a new Lister on the market — boldly called the Thunder. The Thunder is based on the F-Type, but its supercharged 5-liter V8 has been re-engineered to reach 666 horsepower. It will reach 62 mph in just 3.2 seconds, 100 mph in 6.8 seconds and go all the way to 208 mph. To compare a production F-Type SVR to the Thunder, the Jaguar-badged car has 99 less horsepower and takes half a second longer to hit 62 mph. There will only be 99 units built, and they are priced at almost $200,000 in the UK — we reached out to Lister for a confirmation whether the cars will be made available to U.S. buyers. But they are selling out soon, as Lister today announced that in the 24 hours since the unveiling of the Thunder, 22 customers already put in an order, worth in excess of $4.37 million. But the Thunder will be much more than a limited edition plaque in the dashboard (and that 99 extra horsepower); the paintwork and the interior will be bespoke to the specially built car. The modifications to turn an F-Type into a Lister Thunder will be carried out at Lister's historic facility in Cambridge, UK.

Jaguar designs Tour de France racing bike [w/video]

Jaguar is known for designing luxury sedans, and it's known for designing GTs. But once in a while it dabbles in a new area of transportation design. It's working on its first crossover at the moment, and even did a speedboat concept a couple of years ago. Now it's turned its attention to bicycles.
While many automakers have designed bikes in the past, Jaguar's project has a bit more of a direct correlation. It's been working with Team Sky - the outfit that has won the Tour de France two years running now - since 2010, furnishing the team with support vehicles for bicycle races around the world. But now it's stepping its collaboration up a notch by redesigning the team's bike.
Working with frame manufacturer Pinarello, Jaguar took the existing Dogma 65.1 racing bike design back to the drawing board. Jaguar's designers and engineers reshaped the frame tubes, seat post, front fork, derailleur and all the components attached to the frame, each part streamlined for aerodynamic efficiency. They ran it through Jaguar's Computational Fluid Dynamics processor 300 times then verified the results in the wind tunnel.
