Audi reveals S3 Cabriolet ahead of Geneva debut

It used to be if you wanted an Audi S3, your choices in bodystyle came down to hatchback or... hatchback. That is, in markets where the model was offered at all. But Audi has been expanding the A3 global family upon which the S3 is based, and it intends to offer the performance-minded derivative as a three-door hatch, five-door hatch, four-door sedan and - with the introduction of the version you see here - a two-door convertible.
Set to be presented in public for the first time at the Geneva Motor Show early next month, the new Audi S3 Cabriolet packs the same 2.0-liter turbo four as its fixed-roof counterparts - all 290 horsepower and 280 pound-feet of it - but ditches the extra doors and the tin top in favor of the two-door cabriolet bodystyle of the A3 Cabriolet.
The added weight of the folding fabric roof mechanism and the extra body reinforcement required means that the S3 cabrio takes half a second more to reach 62 miles per hour from a standstill than it would take the sedan version, clocking the run at 5.4 seconds instead of 4.9. This, despite more generous use of magnesium, aluminum and high-strength steel in its construction. Top speed, as is the German custom, remains pinned at 155 mph.

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.

Delphi thrilled with results from autonomous car's cross-country trip

In the first trip across the United States ever made by an autonomous car, engineers from Delphi Automotive were surprised to learn that, in some cases, their vehicle behaved a lot like a human driver. "The car was scared of tractor trailers," said Jeff Owens, the company's chief technology officer. "The car edged to the left just a little bit when it would pass trucks, and that was an interesting observation." Engineers made hundreds of notes throughout the drive, as the autonomous car covered 3,400 miles through 15 states en route to a showcase near the New York Auto Show. Overall, company officials said the car performed better than anticipated in a variety of road and weather conditions. In the course of the cross-country drive, drivers actually controlled the car only for about 50 miles, and those cases were limited to on-and-off ramps and the occasional construction zone where lanes were not marked or only sporadically marked. The purpose of the trip was to glean information on how the autonomous car worked in a real-world environment. Google and others have tested autonomous cars and autonomous features in select real-world environments before, but Delphi's adventure was the first to trek into a test with such varied challenges over a nine-day trip that began near the Golden Gate Bridge on March 22. There are some things the engineers have already learned, like the fact the camera systems had the occasional blip when the sun-angle was low. And there are some things to still be learned, as they pour over three terrabytes worth of data from cameras, radar and lidar sensors in the weeks ahead. "It's going to take us a couple weeks to digest all this," Owens said. "But we had all the data from tests. It was time to put this on the road." Built into an Audi SQ5, the vehicle was striking, if only for the fact it looked like a normal car. Many other autonomous vehicles have quirky sensors atop the roof or other features that make them stand out as experiments. Delphi arranged this one to look as much like a normal car as possible, right down to stowing an army of computers under cargo mats, so the rear contained as much trunk space as the production model. If a fellow motorist didn't know where to look -- or take the time to notice the person in the driver's seat didn't have their hands on the wheel -- there was no reason to suspect this was anything other than a regular car.
