Audi RS3 spy shots foreshadow an ultra-hot hatch

Not all vehicle prototypes and mules require heavy camouflage - sometimes they can be hidden in plain sight. That's probably what Audi was hoping for while testing its new RS3 wearing S3 duds, but thanks to some visual and audible telltales, our spy photographers were able to recognize this as a precursor to the marque's ultra-hot hatch testing near the Nürburgring.
Our photographer noticed the signature exhaust note of a five-cylinder engine, which suggests the RS3 could borrow its motivation from the excellent TT RS. Producing at least 340 horsepower, this 2.5-liter turbo powerplant could be the perfect answer for the new A45 AMG from Mercedes-Benz. The big brakes on this RS3 mule give us our best idea about the car's high-performance intentions, with Audi RS wave brake rotors and six-piston calipers peering out from behind the oversized wheels.
In production form, the RS3 should have a much different appearance from what you see here, with sportier design cues including oval-shaped dual exhaust outlets and a more aggressive front fascia. While we're still waiting for our first taste of the S3 in the North America, we'll be holding our breath for the RS3 to make its way here, as well.

Next Audi R8 to eschew engine downsizing, go on diet instead

Looking across the Audi landscape, many models that used to get the company's high-revving, naturally aspirated 4.2-liter V8 are now powered by smaller, yet similarly powerful, forced-induction engines. From what Auto Express is reporting, though, the next-generation Audi R8 will not meet this same fate.
Rather than ditching its V8 and V10 powerplants, the next-gen R8 - expected to debut in 2015 - will shed pounds from its curb weight. The 2014 R8 currently weighs between 3,583 pounds and up to 3,957 pounds, but the report says that engineers are targeting a weight of less than 3,300 pounds. All models will get cylinder deactivation, which along with lower curb weights should help to improve fuel economy and emissions. Head on over to Auto Express for more reported information as well as a handful of renderings that take a stab at how the next R8 may look.

How Audi will make roads friendlier to autonomous cars

Today, Audi announced some of the new projects it will be implementing on Germany's Digital Motorway Test Bed, which comprises a few sections of highway on which the government and industry can test autonomous and connected tech. Among Audi's projects is one specifically aimed at making roads easier for autonomous cars to navigate. Audi is looking to make the road and other objects more visible. The company has been researching materials that could make guardrails and road markers reflect radar waves more readily, and Audi will install test versions soon. The goal here is to help make these objects easier for the autonomous vehicle's sensors to see in inclement weather, and at greater distances in good weather. The company will also test additional road markings that will be easier to see for onboard cameras and will help the car place itself on the road. Audi will also try out new vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I) technology that will be able to alert cars to speed limits, traffic conditions, ice patches and possibly allow for driving patterns such as platooning. This will be a significant step above the traffic light communication system Audi has released in select areas. The company will also be working on very detailed mapping of the area. Audi claims it will be accurate down to the centimeter. From what we've seen at MCity, the world as it stands presents all kinds of difficulties for autonomous vehicles, from worn-out signs to rough pavement. So any advances that make it easier for autonomous cars to see and communicate should help bring such vehicles to reality much sooner.
