Xcar flogs the 2016 Audi RS3

In its latest video, Xcar reckons that just as hypercars from brands like Pagani and Koenigsegg are taking supercars to a new level, the hyper hatch is now supplanting the hot hatch. Roughly defined as three- and five-door models making well in excess 300 horsepower, the reviewer holds up the new Audi RS3 as the poster child for this high-speed revolution that brings huge performance in a quite useful package. With 362 hp and 343 pound-feet of torque from its 2.5-liter turbocharged five-cylinder and a seven-speed dual-clutch gearbox, the RS3 certainly doesn't lack for performance. Audi claims that it can get to 62 miles per hour in 4.3 seconds and to a top speed of 174 miles per hour. Xcar portrays that power as quite livable, though. Apparently, this hyper hatch is made less for top performance at the track, than being sublime on the road. It seems that this hyper hatch isn't destined for these shores, though. Audi isn't bringing the five-door RS3 to the US, but a version in the body of the A3 sedan is highly rumored. If it's as wonderful as Xcar portrays the five-door, then this might be one to look forward to.

Nine-time Le Mans winner Tom Kristensen to retire

Le Mans icon Tom Kristensen is retiring. The Danish driver, who was an integral part of Audi's absolute dominance at the 24 Hours of Le Mans, captured a record-breaking nine wins at the legendary endurance race, along with six overall victories at the 12 Hours of Sebring in a career that spanned 26 years.
"Over the past couple of months, my thoughts of retiring have been stronger, and therefore, it feels right to inform you today that I am retiring from motor racing," Kristensen told Autosport. "I still feel I am in peak physical form and possess the necessary mental toughness both in and outside of the car: it has been important for me to stop while I am still strong and able to deliver top performances at Audi."
While the World Endurance Championship's season-ending race at Interlagos on November 30 will be Kristensen's last as a driver, it won't be the end of his long-running association with Audi. According to Autosport, TK will take on a new role as an ambassador for the German marque and will work with team's drivers in an unspecified role.
