Audi S3 Cabriolet is a topless two-door temptress

Now that we've driven the Audi S3, we're pretty eager for it go on sale in the United States. And while we won't get the Sportback version, there's a teeny tiny chance that Audi may grace us with this new Cabriolet version that makes its debut at the Geneva Motor Show this week.
That certainly wouldn't be a shame, considering the topless S3 packs the same 290 horsepower and 280 pound-feet of torque as the sedan, all of which comes from a turbocharged, 2.0-liter inline four-cylinder engine. That folding roof mechanism adds a bit of weight to the S3 package, and thus, reaching that ever-so-special 62 miles per hour takes an extra half a second - 5.4 compared to 4.9 with the S3 sedan.
Looks-wise, we dig the aggressive little S3, though the chrome wheels of the show car are kind of throwing us off. Swap out a set of standard alloys, and we'll be good to go. Have a look in the gallery above to see the topless Audi for yourself.

Audi A5 DTM diesel sport coupe thumbs nose at scandal

While the diesel emissions scandal is damaging the reputation of the four-cylinder TDI engines, the torquey, fuel-efficient 3.0-liter TDI V6 at the heart of this latest special edition from Audi is so far unsullied. However that doesn't mean the 3.0 couldn't face investigation at some point in the future before the issue is settled. In the meantime, those outside of North America can look forward to the Audi A5 DTM edition's enticing features. The A5 DTM edition is powered by the same 3.0-liter V6 TDI that we can already get in the A6, A7, and A8 sedans as well as the Q5 and Q7 crossovers. Here, it produces 245 horsepower and 427 pound-feet of torque (in the US-spec A6, the engine is quoted as making 240 hp and 428 lb-ft). The A5 DTM channels its power to all four wheels through a seven-speed dual-clutch transmission. That's enough to propel it to 62 in a claimed 5.9 seconds and an electronically-governed top speed of 155 miles per hour. The sporty look is inspired by Ingolstadt's DTM touring car program. That includes a sportier front fascia, Misano red paint, gloss-black trim, 20-inch split-five-spoke alloys, and special badges inside and out. The interior packs the bucket seats from the RS5, Alcantara trim, stainless steel pedals, and more. Audi will only offer 50 examples, priced in Germany at ˆ74,540 – equivalent to about $85k at current exchange rates. Racing spirit – The Audi A5 DTM selection limited-edition model - Limited run going into production from October - 20-inch wheels, bucket seats and Misano red finish - Third DTM special edition from Audi Audi is taking the spirit of the DTM from the racetrack to the road – with the Audi A5 DTM selection* special edition. A powerful 3.0 TDI developing 180 kW (245 hp), 20-inch wheels, dynamic design and bucket seats reveal the two-door coupe's connections with the race version that has featured in the German Touring Car Masters (DTM). The Audi A5 DTM selection turns heads with its special racing design. The front lid, doors and rear window are emblazoned with dynamically designed DTM, quattro and Audi Sport logos. The Misano red paint finish contrasts with high-gloss black add-on parts on the front, sills and rear, giving added emphasis to the sports appeal of this limited-edition model. The front apron and the large air inlets with their rhombus-pattern grilles also contribute to its special looks. The cast aluminum wheels by Audi Sport embrace a five twin-spoke design in matt titanium look.

Watch Stanford's self-driving Audi hit the track

Sending a self-driving race car around a track with nobody inside seems pointless – there's no driver to enjoy the ride, and the car certainly isn't getting a thrill out of it. But the students performing research with Stanford University's Audi TTS test rig "Shelley" (not to be confused with Audi's own self-driving race cars) are getting a kick out of the numbers generated by the machine. "A race car driver can use all of a car's functionality to drive fast," says Stanford Professor Chris Gerdes. "We want to access that same functionality to make driving safer." The teams push the car to speeds over 120mph and the computers have executed lap times nearly as fast as professional drivers. However, they also spend a lot of time maneuvering at 50 to 75 mph, the speeds where accidents are most likely to happen. That way, the students can figure out how to incorporate braking, throttle and maneuvering to develop new types of automatic collision avoidance algorithms. Better technology, for instance, could have saved Google from a recent slow-speed accident where its vehicle was struck by a bus. During race days, students break into teams to perform different types of research. "Once you get to the track, things can go differently than you expect. So it's an excellent lesson of advanced planning," says Gerdes. In the latest rounds of testing, for instance, one PhD student developed emergency lane-change algorithms, while another recorded a skilled human driver in an attempt to convert his behavior into a driving algorithm. The main goal, of course, is to prepare students for something they may not have expected -- an automotive industry that is adopting self-driving technology at breakneck speeds.
