Audi RS7 prototype is world's sportiest self-driving car [w/video]

Audi may not be the only automaker out there toying with self-driving automobile technology, but it is arguably the fastest of them. A few years back, it raced unleashed a driverless TTS on the Bonneville Salt Flats, then sent it up Pikes Peak and around Thunderhill. But now it's taking things a step further with the vehicle you see here.
This RS7 Sportback has been fitted with steering, brakes, throttle and transmission hooked up to a computer system that combines GPS, high-frequency radio signals and 3D imaging camera to drive the vehicle autonomously not just in slow-paced, stop-and-go traffic, but around the track at the same pace a professional racing driver would push it: full throttle on the straights, full braking before the corner and 1.1-g of cornering force.
As promised, Audi plans to unleash the self-driving RS7 - which it calls "the sportiest piloted driving car in the world" - at Hockenheim next weekend prior to the DTM season finale, where it is anticipated to pull a 2:10 lap time. The next stage will be to set it lose on the Nürburgring Nordschleife, all 154 turns and 13 miles of it, which ought to pose a heck of a challenge to the engineers from Ingolstadt. In the meantime you can scope it out in the high-res image gallery above and the second teaser video below.

Audi considering other variants, turbo V6 for R8

More details from the Audi R8 event at Spain's Ascari circuit have met the Internet, and they provide more intel on the supercoupe will evolve over the second generation. First, they note some small differences in stance with this new car, being wider than the current car and sitting 30 millimeters (1.18 inches) lower. Compared to its Lamborghini Huracan brother, it gets three extra centimeters in the wheelbase. Filling out the power numbers, the 'entry-level' V10 engine at launch rolls out 540 horsepower and 399 pound-feet of torque, does the 0-60 mile per hour dash in 3.5 seconds, and hits a top speed of 200 mph. The V10 Plus model rocks 620 hp and 412 lb-ft, which slices 0.3 seconds off that acceleration time and adds five more mph to the top speed. They'll transfer their power through a seven-speed S-tronic that shifts faster than before, and it will in turn send power through an electronically-controlled clutch at the front axle and a constantly variable limited-slip differential at the rear axle. The power split is said to default to 42/58 front-to-rear, but 100 percent of the torque can be sent fore or aft. Benchmarked against the 991-series Porsche 911, driving sensations travel through an electromechanical steering setup that can be had with a variable rack if preferred, leading to standard 19-inch wheels with the option of 20-inchers and tires developed specifically for this car. A Performance setting offers dry, wet, and snow modes; that first setting turns the ESC off except for situations of impending doom, and Audi racer and test driver Frank Stippler told Top Gear that understeer is reduced, to which TG added "it oversteers at will." Stippler said it's "a lot closer to the GT3 race car than ever before," and even though it's "a lot" less intense than the Huracan, it's just as fast on the track. His estimate is that the new R8 will lap the Nurburgring between ten and 15 seconds faster than the current car. R8 technical lead Roland Schala said the new chassis opens up new avenues of development because "there's no problem to change it," mentioning models like a Clubsport or Superleggera as no longer forbidden. Differentiation could come from a wider engine mix, too. Markets like China need smaller displacements, so Audi's twin-turbo V8 is expected to join the line-up at some point, bringing 500 horsepower.

2016 Audi TTS

We recently drove the Audi TT, and although we wish it were radically entertaining instead of merely very fun, it's nevertheless a sharp coupe that vaults ahead of its predecessor with an inspired interior and eager handling. That car will be precursor to this TTS when it gets here a year from now, with the TTS adding adjectives like "more" and "better" to just about everything found on the base coupe. With the standard car having already put on such a fine edge, we wheeled the TTS on Spanish roads and at the Ascari race track to find out how much better and higher-performing the S will be.
Driving Notes
As of this writing, today's TTS commands an $8,350 premium over the TT. Assuming a commensurate gap is carried over into this next generation model, that supplemental dosh will get you 310 horsepower and 280 pound-feet of torque instead of 230 hp and 273 lb-ft in the standard TT. That would mean more for your money, too, since the gap between the current TT and TTS is 54 hp and zero lb-ft of torque. To achieve the new numbers, the 2.0 TSFI engine from the TTS benefits from upgrades like sturdier valves, revised aluminum pistons and stronger connecting rods with new bearings, a reinforced crankshaft and a high-performance intercooler. The amplified brawn rips 0.7 seconds off the 0-60 mile-per-hour time, getting you there in 4.6 seconds.
