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.

Watch four hours of fantastic machinery at Le Mans Classic 2016

The 24 Hours of Le Mans came and went, but it wasn't the end of the automotive activities at Circuit de la Sarthe. This past weekend, the venerable racetrack was host to the 2016 Le Mans Classic, in which seven decades of vintage racecars once again competed for glory. The event started with qualifying on Friday, July 8, and racing on the following Saturday and Sunday. Six "grids" of cars each included a different historic racing era, including the early days from 1923 to 1939, as well as that famous period from 1966 to 1971 that featured the all-conquering Ford GT40. The wide range of eligibility also permitted some unusual machines to show up, such as a 1950 Cadillac Series 61 and a 1974 Dodge Charger. This year also marked the debut of the Group C class for more recent Le Mans racers from 1982 to 1993. The 1991 Le Mans-winning Mazda 787B was not present, but one of the Peugeot 905 race cars that gave the marque a remarkable 1-2-3 finish at the 1993 Le Mans came back for the event. The Le Mans Classic also featured the Jaguar Classic Challenge just for cars made by the feline automaker, and the race attracted a bit of human star power. Chris Harris of Top Gear participated in the marque-specific race while behind the wheel of a new continuation Lightweight E-Type. And although the event happened over the weekend, you can catch most of the action via the recorded live stream above. It features a full four hours of vintage racing with commentary in both French and English. It's a great chance to see one of the best combinations of classic cars and historic venues out there.

Jaguar tests autonomous vehicle technology with 100-car fleet

Jaguar Land Rover is exploring how to take autonomous vehicle technology off the paved path. But the company has plans for technology on tarmac, too. The company announced that the Jaguar division will have a fleet of 100 cars testing autonomous technologies on public roads. The testing process will cover a period of four years and begin with vehicle-to-vehicle and vehicle-to-infrastructure communication systems, along with a stereo camera system and autonomous vehicle software. These systems will work together to provide a variety of features that could make their way into future Jaguars and Land Rovers. The first feature in development is called "Roadwork Assist." The system relies on the stereo camera to create a 3D image the car's software can analyze. The software can identify road cones and other barriers associated with construction sites. The car will then alert the driver about entering the construction zone and provide some steering assistance to keep the car centered in its lane. Tony Harper, Jaguar's head of research, said that this system can reduce stress on the driver, and the technology could eventually be used to allow the car to pilot itself through construction zones. Another of Jaguar's proposed features is "Safe Pullaway," which also relies on cameras and software. The Safe Pullaway feature is designed to prevent close-proximity collisions in traffic jams and even in the garage. To do this, the car watches the area immediately ahead of it for obstacles. If the car detects something nearby while the driver adds throttle or shifts into gear, it will apply the brakes to prevent driving into the object. The final project on Jaguar's plate is its "Over the Horizon Warning" system. This will be one of the first features to rely on Jaguar's vehicle-to-vehicle communication technology. The idea is that connected cars in constant communication will give drivers additional warning of upcoming hazards, such as out-of-sight animals and slowed or stopped cars. In Jaguar's example of a stopped car, the stationary vehicle would send a signal alerting approaching cars of the situation. In turn, the approaching vehicles would trigger audible and visual warnings to drivers about the hidden car. Jaguar says that the system could also be applied to emergency vehicles. Emergency vehicles would broadcast a signal to alert drivers well before the lights and sirens get their attention. This would give emergency vehicles a faster, safer path through traffic.
