Audi to lap Hockenheim in driverless RS7

An automaker like Audi will always have a number of different research and development projects going at the same time, and some of them might take on very different approaches. At one end, you'll have its racing programs, and at what you'd assume would be the other, self-driving prototypes. But Ingolstadt is preparing to bridge that gap by running an autonomous prototype at racing speed around the famed Hockenheimring.
Set to take place on Sunday, October 19, during the DTM season finale at Hockenheim, the driverless RS7 will motor at speeds up to 150 miles per hour, right up "to its physical limits with millimeter precision."
Audi anticipates that "the world's sportiest piloted driving car" will run a lap time of just over two minutes, at which the RS7 would stand not only to be the fastest driverless car ever to lap the circuit, but also potentially the fastest four-door - if it can beat the 2:02.71 lap time set by a BMW M3 sedan in 2007.

Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

Audi Traffic Light Assist helps you hit every green light

Before taking a ride in Audi's impressive Piloted Driving A7, we took a short spin up and down the Las Vegas strip to check out a smaller, but intriguing piece of Audi driver assistance technology called Traffic Light Assist that promises to help drivers make every green light.
Using both live and predictive data beamed into the vehicle's navigation unit via onboard wifi, TLA doesn't need a single camera to tell you when the light is going to change. Local data sources provide information about traffic light patters, and the in car system uses that data and the motion of the car to predict exactly how long it'll be until the green light goes red.
In practice, the system shows a traffic light icon in the central display (a head-up display would be a nice option), along with a countdown timer that reads the number of seconds before a light changes from red to green. Additionally, the system corrects (nearly instantly in our demo) for changing lanes and resultant changing signals; changing a straight-through traffic lane to a left-turn lane and signal, for instance.
